Privacy Policy
Last Updated: May 27, 2026
Compliant with Digital Personal Data Protection Act (DPDPA) 2023, India
Our Core Privacy Promise
ShareLync operates on a Zero-Knowledge Architecture. This means your bio-data is encrypted on your device before it reaches our servers using AES-GCM encryption. We (ShareLync) do not hold the decryption keys, which means we physically cannot read your profile data or personal information. Profile photos are stored securely on Firebase Storage with authenticated access controls. Full photo encryption is on our roadmap.
Notice & scope (DPDPA 2023, Section 5)
This Privacy Policy constitutes the notice required under Section 5 of the Digital Personal Data Protection Act, 2023 (“DPDPA”) and the rules made thereunder. It informs you, the Data Principal, about the categories of personal data we process, the purposes for which we process it, the manner in which you may exercise your statutory rights under Sections 11–14 of the DPDPA, and the manner in which you may submit a complaint to the Data Protection Board of India.
Data Fiduciary: “ShareLync” refers to the founders Alefiya and Zainab operating the service at sharelync.app and its subdomains (hub.sharelync.app and admin.sharelync.app) from India. ShareLync is the Data Fiduciary for personal data collected through the consumer mobile and web applications and the Introductions Hub Owner surface. Contact: admin@sharelync.app.
Legal basis for processing. We process personal data on the basis of your free, specific, informed, unconditional, and unambiguous consent (DPDPA Sections 6 and 7(a)), signified by your affirmative action of creating an account, submitting a waitlist form, or accepting an invite, as the case may be. Where a processing activity is grounded on a different basis (for example, processing payment data through a payment aggregator for a contract you have entered into, or retaining audit-trail records to comply with a legal obligation under DPDPA Section 8(7)), the alternative basis is identified inline in the relevant section below.
Withdrawal of consent (DPDPA Section 6(4)). You may withdraw any consent you have given to ShareLync at any time, by writing to admin@sharelync.app from your registered contact, by tapping “Delete account” in the mobile app, by replying STOP to a WhatsApp message we have sent, or by clicking the unsubscribe link in any email we have sent. Withdrawing consent does not affect the lawfulness of processing carried out before withdrawal, and may necessarily affect our ability to continue providing parts of the service that depend on the withdrawn consent.
Definitions used in this notice. Capitalised terms have the meanings given to them in the DPDPA. In particular: “Personal Data” means any data about an individual who is identifiable by or in relation to such data; “Data Principal” means the individual to whom the Personal Data relates; “Data Fiduciary” means the person who determines the purpose and means of processing; “Data Processor” means a person who processes Personal Data on behalf of a Data Fiduciary; and “Processing” means a wholly or partly automated operation performed on Personal Data.
Grievance Officer. Per DPDPA Section 8(9), ShareLync has designated a Grievance Officer (see Section 14 below). The Grievance Officer will respond to your request or complaint within 72 hours of receipt and will act on substantive matters within the timelines set out in Section 10.
1. Information We Collect
We collect minimal data necessary to operate the service. This is broken down into the following categories:
Account Information (Visible to Us)
- Phone Number - For OTP verification via Firebase Authentication (when you sign in with phone)
- Email Address - When you sign in with Google or Apple, your email (or Apple's private relay address if you choose 'Hide my email') is stored as part of your account
- Display Name - When you sign in with Google or Apple, your name is stored as part of your account
- Firebase User ID - A unique identifier for your account
- Device Information - Device type and OS for app compatibility
Account Recovery Hash: When you create or sync a profile, we compute a one-way cryptographic hash (HMAC-SHA-256) of your phone number or email using a server-side secret that never leaves our backend. This hash is stored alongside your encrypted profile so you can recover your account on a new device using the same sign-in method. The original phone number or email is NOT stored in plaintext alongside your encrypted profile, and the hash itself cannot be reversed to recover the original value.
Encrypted Profile Data (NOT Visible to Us)
The following data is encrypted on your device before upload. To our servers, this appears as random encrypted data:
- Personal Details: Full name, date of birth, gender, height, marital status, physical status
- Cultural Background: Community, caste, sub-caste, gotra, manglik status
- Education & Career: Education level, occupation, employment type, annual income, work location
- Location: Country, state, city, residential status
- Family Details: Father's occupation, mother's occupation, siblings information, family type, family values
- Lifestyle: Diet preferences, smoking habits, drinking habits
- About Me: Personal bio/description
- Partner Preferences: Your personal preferences and priorities
- Profile Photos: Up to 6 photos (compressed and encrypted)
Optional Link Preview Data (Public Card)
When you enable 'WhatsApp Link Preview' in Settings, the following minimal data is stored separately in unencrypted form to power social media link previews:
- Display Name - Your name shown in the preview card
- Location - City and state for the preview card
- Profession - Your occupation shown in the preview
- Profile Photo - Your primary photo shown in the preview
Link Preview Control: This feature is optional and enabled by default. You can disable it anytime from Settings → Privacy. Disabling instantly deletes the public card from our servers. All other profile data (salary, education details, family info, religion, caste, lifestyle preferences) is NEVER included in link previews and remains end-to-end encrypted.
Locally Stored Data
Some data is stored only on your device and never sent to our servers:
- Profile Slug/Username - Your unique shareable link identifier is stored only locally
- Draft Photos - Temporarily stored during profile creation
- Cached Profile Data - For offline access
App Analytics & Improvement (Anonymous, First-Party)
To maintain app stability and improve the user experience, we collect anonymous, first-party usage data. This data is processed internally and is not shared with third-party advertising networks or data brokers.
- Crash Reports - Technical logs (stack traces) when the app malfunctions, to help us fix bugs
- Usage Metrics - Aggregate counts of features used (e.g., 'Profile Created', 'Share Clicked') to understand product performance
- Attribution - Anonymous data on how you opened the app (e.g., via a shared link or QR code) to measure our invite system
Privacy Protection: We have disabled the collection of the IDFA (iOS) and Advertising ID (Android). No ad tracking is performed. This analytics data is not linked to your name, phone number, or payment details. We collect this data strictly for the purpose of app functioning, security, and product improvement.
Viewer Analytics (Anonymous, IP-Derived)
When someone views a biodata via a shared link, we collect anonymous, approximate location data to help profile owners understand where their biodata is being viewed. This data is derived from the viewer's IP address and is never linked to any personal identity.
- Approximate Location - City, region/state, and country derived from the viewer's IP address using a server-side geolocation database. Accuracy varies (typically city-level in urban areas, less precise in rural areas)
- Visit Count - How many times the same device has viewed the biodata, for deduplication
- Timestamps - When the first and most recent view occurred
- Device Hash - A one-way cryptographic hash of the device identifier (mobile app) or IP address (web browser). The original identifier is never stored
Viewer Privacy: Viewers remain completely anonymous. Profile owners can see approximate locations and visit counts, but never names, phone numbers, photos, or any other identifying information about who viewed their biodata. No location permissions are requested from viewers — all location data is derived server-side from IP addresses, which is standard web analytics practice. IP addresses are hashed immediately and never stored in plain text.
AI-Processed Data (Temporary)
When you upload a biodata document or image for automatic profile creation, it is processed by a third-party AI service to extract profile information:
- Uploaded Document - Your biodata PDF or image is sent to Google Gemini AI for text extraction and field mapping
- Extracted Fields - The AI reads your document to fill in profile fields (name, education, family details, etc.)
- No AI Training - Your data is processed via Google's API and is NOT used to train or improve AI models
- Automatic Deletion - Your uploaded document is automatically deleted from our temporary servers within 30 seconds after processing
AI Processing Transparency: The AI only extracts text and structured data from your uploaded document to pre-fill your profile form. You can review and edit all extracted information before saving. The original document is never stored permanently — it is deleted from our servers within 30 seconds of processing.
Age Protection: In compliance with DPDPA 2023, we do not collect analytics data from users under 18 years of age. Our app is intended for adults (18+) only.
2. How We Use Your Information
We use your data solely for:
We use first-party analytics (Firebase) to improve app stability and performance. This data is not shared with third-party ad networks.
3. Third-Party Services
We use the following trusted third-party services:
- Firebase (Google): For authentication (phone OTP, Sign in with Google, Sign in with Apple), cloud storage, and privacy-preserving analytics (with Advertising ID disabled). Firebase processes data in accordance with Google's privacy policies and our strict configuration to block ad tracking.
- Sign in with Google: Optional sign-in method. When you choose this, Google authenticates you and shares your email address and display name with ShareLync. We do not request access to your Google contacts, calendar, or other Google services. Google's handling of your data is governed by Google's Privacy Policy.
- Sign in with Apple: Optional sign-in method. When you choose this, Apple authenticates you and shares your email address and (on first sign-in only) your full name with ShareLync. If you choose “Hide my email,” Apple provides a private relay address (‘xxxx@privaterelay.appleid.com’) which forwards email to your real address — we never see your real email in this case. Apple's handling of your data is governed by Apple's Privacy Policy.
- Firestore Database: Stores your encrypted profile data. We only store the encrypted blob - the actual content is unreadable without your unique link.
- Google Gemini AI: Used to analyze and extract information from uploaded biodata documents during profile creation. Documents are processed via Google's API and are not used for AI model training. Processing is governed by Google's Gemini API Terms of Service.
- Google Cloud Functions: Used to temporarily receive and process uploaded documents for AI extraction, and to compute the account-recovery hash described above. Documents are automatically deleted within 30 seconds of processing.
- Meta WhatsApp Business Cloud API: Used to deliver a one-time qualification message via our verified ShareLync Business number when you submit a phone number to the Introductions waitlist (see Section 6). Meta receives your phone number, the rendered text of our message, and Meta-side delivery status callbacks (sent / delivered / read / failed). Meta's handling of this data is governed by Meta's WhatsApp Business Policy and Privacy Policy.
- Razorpay: Payment processor for paid Hub Owner subscriptions (see Section 7). When you pay for a paid plan, Razorpay receives the payment instrument details you enter on their hosted checkout — ShareLync does NOT see or store your card / UPI / netbanking credentials. Razorpay returns only the payment status, transaction ID, and the masked instrument summary to our servers. Razorpay's handling is governed by their Privacy Policy.
We do NOT sell your data to advertisers or any third parties.
4. Data Sharing & Disclosure
We do not sell, rent, or trade your personal data.
Since we cannot read your encrypted bio-data, we cannot share it with advertisers or third parties even if we wanted to.
Legal Requirements: If required by Indian Law Enforcement agencies under valid legal process, we may share your Account Information (Phone Number, Firebase UID). However, we cannot share your Bio-Data contents as they are end-to-end encrypted and we do not possess the decryption keys.
Profile Sharing: When you share your profile link with someone, they receive access to decrypt and view your profile. You control who receives this link.
Link Previews: When the Link Preview feature is enabled, a minimal public card (name, location, profession, photo) is stored in unencrypted form to generate social media preview cards (e.g., WhatsApp, Telegram, Twitter). This data is publicly accessible via the shared link but contains no sensitive details. You can disable this feature at any time, which immediately deletes the public card.
5. Family Hub (Optional Feature)
Family Hub is an optional feature that lets one ShareLync user (a “Hub Owner”) invite other users to add their biodatas to the Hub Owner's network. It is typically used by families managing biodatas on behalf of multiple relatives, or by community members who help others present their biodata. The feature is OFF by default and only becomes available when ShareLync enables it via Remote Config.
What the Hub Owner sees about you (if you join their Family Hub):
- The same minimal Link Preview fields described in Section 1 above: your name, city/state, profession, and primary photo.
- The fact that your biodata is part of their hub (an entry in their portal).
- Nothing else. Your encrypted biodata — date of birth, family details, partner preferences, contact information, additional photos, salary, education details — remains encrypted on your device with a key only you control. The Hub Owner cannot decrypt it without the link you choose to share.
How invites work: The Hub Owner generates a one-time invite link. The link contains a short random code; the code is the only secret. We store the invite (including the name the Hub Owner typed for you and any short note they wrote) in our database so the landing page can display it to you. This invite document is readable by anyone who has the link. Do not forward an invite link you received until you've read the landing page and decided whether to accept.
Your consent and your rights:
- Affirmative consent. Before your biodata enters a Hub Owner's portal, you must tick a consent checkbox on the invite landing page that explicitly identifies the Hub Owner and the data fields they will see. The Continue button is disabled until you tick it.
- Leave at any time. You can remove yourself from a Family Hub from your dashboard. The Hub Owner stops seeing your biodata immediately; your biodata itself stays yours and untouched.
- Erasure. If you delete your ShareLync profile, your entry is removed from the Hub Owner's portal automatically and the invite that bound you to the hub is invalidated.
- Independent users. Hub Owners are independent ShareLync users, not ShareLync employees or agents. We do not control how a Hub Owner uses the information you choose to publish.
DPDPA 2023 notice (recipients of your personal data):
For the purposes of Section 5 of the DPDPA 2023, the following parties may receive your personal data when you join a Family Hub:
- ShareLync (Data Fiduciary) — receives the encrypted biodata and the minimal Link Preview card, as described in Sections 1, 3, and 4 above.
- The Hub Owner you joined — receives the Link Preview card fields (name, city/state, profession, photo) and the fact of your hub membership. The Hub Owner becomes a recipient of your personal data; we do not control their downstream use.
- Anyone with the invite link — can see the inviter's display name, the name the inviter typed for you, and any short note they wrote. Do not forward invite links carelessly.
6. Introductions Waitlist & Outreach
ShareLync operates an invitation-only waitlist for the Introductions product (the Hub Owner customer relationship management surface at hub.sharelync.app). Two web surfaces accept waitlist submissions: the “Introductions” section on the main landing page at sharelync.app, and the dedicated outreach page at sharelync.app/for-matchmakers (the latter being an unindexed page disclosed to potential customers in the course of one-to-one outreach). This Section describes the categories of Personal Data we collect through those forms, the purposes for which we process them, the lawful basis under the DPDPA, the third parties to whom we disclose them, and the manner in which you may exercise your rights.
Lawful basis (DPDPA Sections 6 & 7):
Processing of waitlist submissions and any subsequent outreach communications is grounded on your consent under DPDPA Section 7(a), signified by your affirmative action of clicking the “Request early access” or “Join the waitlist” button after having been shown, immediately above the button, a plain-English notice describing what will happen (including, if you have submitted a phone number, that you will receive a one-time WhatsApp Business message). You may withdraw this consent at any time by the means described in “How to opt out” below; withdrawal does not affect the lawfulness of processing carried out before withdrawal.
What the waitlist form collects:
- Your name (required) — used to address you in the qualification message.
- WhatsApp number or email (at least one required) — the channel we'll use to reach you. The phone number is normalised to international E.164 format (e.g. +91…) using the country you pick from the dropdown.
- City (optional) — helps us route you to a peer matchmaker we already work with in your area.
- Approximate biodatas you handle today (optional — 1-5, 5-20, or 20+) — qualifies the lead so we can prepare the onboarding conversation.
- Source tag — automatically set to the form you used (landing-introductions or for-matchmakers). Used to measure which outreach channels work.
- Submission timestamp.
WhatsApp Business contact — affirmative consent: If you submit a phone number, the form displays an explicit notice that submitting authorises ShareLync to send one WhatsApp message from our verified ShareLync Business number via Meta's WhatsApp Cloud API. The message introduces the founders (Alefiya & Zainab), thanks you for joining, and asks three short questions (volume of biodatas, current tooling, biggest pain point). The message is sent under Meta's Utility template category — it is not a marketing communication and we send it only once per submission. If you reply, Meta opens a 24-hour “customer-service window” under its commerce policy during which we may exchange freeform follow-up messages with you. Outside that window, we may only re-engage you by means of another approved Utility template, the rendered text of which is recorded in our internal message store; we will not send more than one such re-engagement message per calendar week, and you may opt out of all further re-engagement at any time by replying STOP to any of our messages. The opt-out takes effect immediately upon our receipt of the inbound message; we do not require further action by you.
Cross-border transfer disclosure (DPDPA Section 16):
The WhatsApp Business Cloud API is operated by Meta Platforms, Inc. (a company incorporated in the United States), through subsidiaries and affiliates. Where the WhatsApp Business contact described above occurs, Personal Data (your phone number, the message content, and Meta-side delivery metadata) is transferred to Meta's servers, which may be located outside India, including in the United States and the European Union. We rely on the standard data-processing terms made available by Meta to advertisers and businesses using the WhatsApp Business Cloud API, and on the safeguards Meta represents to maintain under applicable data-protection laws. The Central Government has not, as of the “Last Updated” date above, notified any country as a restricted territory under DPDPA Section 16; if any such notification is made, we will reassess this transfer mechanism. Email transactional messages are delivered by our email provider, which is similarly headquartered outside India; the same disclosure applies. See Section 16 below for the consolidated cross-border-transfer notice.
How we use this information:
- One-to-one outreach. A human on the ShareLync team reads your submission and writes back, on WhatsApp or by email, within a working day. No automated drip campaigns. No third-party advertising lists.
- Onboarding readiness. The qualification answers help us decide whether the product is a fit for you and what to demo on a working call.
- Distribution analytics. We track the count and source of signups internally to measure outreach health. These analytics never include your name or contact details — only the aggregate count per source tag per day.
Storage, security measures, and retention (DPDPA Section 8):
- Submissions are written to a Firestore collection (introducer_waitlist) operated by Firebase / Google Cloud. The collection is gated by Firestore Security Rules so that no client can read, list, update, or delete its documents; only authenticated members of our admin-users allowlist can. Field-level validation rules enforce a minimum and maximum length on each field, a regular-expression check on phone numbers (E.164) and email addresses, and a closed set of permitted source tags.
- Inbound and outbound WhatsApp messages exchanged with our Business number are stored in a separate server-only collection (whatsapp_messages) to maintain a complete conversational record. We store the message text, the recipient or sender phone number, the Meta-generated message identifier (the “wamid”), and delivery-status timestamps (sent / delivered / read / failed). We do not store WhatsApp media payloads (photographs, voice notes, documents) on our servers — only text.
- Qualification emails sent through our transactional-email queue (Firestore collection mail) carry your name, city, biodatas-count answer, and the rendered HTML body, retained for delivery-audit purposes.
- Inbound webhook payloads from Meta are authenticated using HMAC-SHA-256 signature verification against the Meta App Secret before any database write occurs (DPDPA Section 8(4) — reasonable security safeguards).
- Retention period. We retain waitlist submissions, conversational records, and qualification emails for the duration necessary to (a) onboard you as a customer or (b) demonstrate that we have responded to your submission. If you do not respond to our outreach within twelve (12) months and have not been onboarded as a customer, we will treat the purpose as having been served (DPDPA Section 8(7)) and erase your record automatically at the next quarterly retention sweep. If you have withdrawn consent, we will erase the record within seven (7) working days of receipt of the withdrawal request, retaining only that minimum information (your contact identifier and the timestamp of withdrawal) that is necessary to demonstrate compliance with the request itself, for a further period of three (3) years from withdrawal, after which it too is erased.
How to withdraw consent or request erasure:
- Before submission — do not submit the form. The notice above the submit button is the consent moment; the form is not transmitted to our servers until you click the button.
- By WhatsApp, after submission — reply STOP, UNSUBSCRIBE, OPT OUT, or any clear refusal to the qualification message. Our webhook records the inbound message immediately upon receipt; we will not send any further proactive messages and the conversation closes.
- By email, after submission — write to contact@sharelync.app with the subject “Remove me from the Introductions waitlist”, identifying yourself by the phone or email you submitted. We will acknowledge within 72 hours and delete the record (along with the corresponding WhatsApp thread, if any) within seven (7) working days, retaining only the proof-of-erasure entry described above.
- Withdrawing consent does not affect the lawfulness of any processing carried out before the withdrawal takes effect (DPDPA Section 6(4)). Messages that have already been delivered to your WhatsApp client or email inbox are not within our control to retract; you may delete them from your own client.
DPDPA 2023 notice — categories of recipients (Section 5(i)(c)):
- ShareLync (the Data Fiduciary) — reads your submission and any WhatsApp or email replies, and uses them to determine whether to extend an onboarding invitation.
- Meta Platforms, Inc. (Data Processor under DPDPA Section 8(2), acting on documented instructions of ShareLync through the WhatsApp Business Cloud API terms) — processes the WhatsApp messages we exchange. Meta receives your phone number, the message text and template parameters, and returns delivery-status metadata. Meta's servers are located outside India; see Section 16 (Cross-Border Data Transfer).
- Google LLC / Google Cloud / Firebase (Data Processor) — provides the underlying infrastructure on which the Firestore collections, Cloud Functions, and authentication services operate. Personal Data at rest is stored within Google's multi-region storage; servers may be located outside India.
- Our transactional-email provider (Data Processor) — delivers the qualification email if you submitted an email address. The provider receives your name, email, and the rendered email body. The provider is identified in Section 16.
7. Hub Owner Accounts (Introductions Customers)
If you are accepted into the Introductions program, you will receive a one-time invitation token entitling you to claim a Hub Owner account at hub.sharelync.app. This Section describes the categories of Personal Data we collect, retain, and process in connection with the Hub Owner account — distinct from the consumer biodata data described in Sections 1–4 and the candidate-member data described in Section 5. By claiming a Hub Owner account, you accept the additional terms set out in our separate Hub Owner Terms of Service.
Lawful basis (DPDPA Sections 6 & 7):
- Provision of the contracted service — we process your Hub Owner profile, member roster, notes, pairings, share log, activity log, and helper records to provide the Introductions service you have engaged ShareLync to provide.
- Consent (DPDPA Section 7(a)) — for any processing beyond the strict contractual minimum, including diagnostic analytics and product-improvement signals.
- Legitimate use — compliance with a legal obligation (DPDPA Section 7(b) and Section 8(7)) — for the retention of billing, invoice, and audit-trail records to the extent required by applicable tax, accounting, and audit laws.
- Performance of a contract — for the processing of payment instructions and the issuance and settlement of invoices through Razorpay.
Important — your status as an independent Data Fiduciary for your members:
When you, as a Hub Owner, collect, store, or share personal information about candidates and their families — including private notes, pairings, share-log entries, and any information you choose to transcribe into the Hub from external sources — you are acting as an independent Data Fiduciary under DPDPA Section 2(i) with respect to that information. ShareLync acts as your Data Processor in respect of that information under DPDPA Section 8(2); we will process it solely on your documented instructions, in accordance with the Hub Owner Terms of Service. You are responsible for: (i) obtaining and recording the consent of the candidate or family before adding their information to your Hub; (ii) honouring withdrawal of consent, access, correction, and erasure requests received from candidates or families; (iii) complying with the DPDPA in your capacity as their Data Fiduciary. ShareLync provides tools (the affirmative-consent checkbox on invite landing pages, the leave-the-hub flow, the consent-record tombstoning mechanism) to assist you in meeting these obligations, but the legal responsibility for compliance with respect to your members rests with you. Where ShareLync receives a request directly from a candidate or family in respect of information you hold about them, we will forward the request to you and may inform the requester that you are the responsible Data Fiduciary.
Data the Hub Owner provides directly:
- Account identifiers — the Firebase Auth identity you signed in with (phone number, Google email, or Apple email/relay), plus a Firebase User ID.
- Hub Owner profile stored in the hub_owners/{uid} document: display name, optional photo, optional bio, primary city, the slug you publish at /i/<cardSlug> as the Introducer attribution card, and your billing plan / status (see “Billing” below).
- Member roster — the people who accepted your invite. Each entry stores the candidate's Link Preview card fields (name, city/state, profession, photo) plus the binding to your hub. Encrypted biodata content stays with the member — you (and we) cannot decrypt it without the link the member chooses to share.
- Per-member private notes stored at family_hub_notes/{hubOwnerUid}__{memberPublicHash} — freeform text you write about each candidate. Only you can read or write your own notes (Firestore rules enforce this). v1 stores notes in plaintext on the server; v2 will encrypt them with a Hub-Owner-derived key.
- Pairings board (Matches) stored at family_hub_matches/{matchId} — the two candidates you're pairing, the current stage (considering / in motion / engaged / married), stage history, and timestamps. Snapshot fields (name, age, city, photoUrl) are captured at create-time so your record survives even if a candidate later deletes their biodata.
- Activity log stored at hub_activity/{eventId} — an append-only log of share events, member joins, helper invites, and other operational events for your own audit trail.
- Share log — when you share a candidate's biodata link with a family, we record the candidate, the recipient family name (a freeform string you type), channel (WhatsApp / link copy / etc.), and timestamp.
Helpers (Phase B):
You may invite up to a small number of Helpers (a daughter, niece, assistant) to access your hub on your behalf. Each Helper accepts a one-time invite that gives them either full editor or read-only access. We store:
- The Helper's Firebase identity (phone or email + UID).
- The Helper-to-hub binding (which hub they belong to, their permission tier, the timestamp they joined).
- An audit trail of which Helper performed which write (so you can review who edited a member or sent a share).
You can revoke a Helper's access at any time from hub.sharelync.app/team. Revocation is immediate — their session is invalidated and they lose write/read access on the next request. The audit log entries they generated while active are preserved as part of your record (we do not retroactively rewrite history when a Helper leaves).
Billing (paid plans):
- Plan + status stored on your hub_owners document: plan id, billing status (active / trial / past-due / cancelled), monthly rate, currency.
- Invoices stored at billing_invoices/{invoiceId} with the period covered, amount, status, paid-at timestamp, and the Razorpay-side payment link or transaction id.
- Payment instrument data is NEVER stored by ShareLync. All card / UPI / netbanking detail is captured by Razorpay on their hosted checkout page. Razorpay returns to us only the transaction id, paid amount, masked instrument summary (e.g. “Visa ending 4242”), and the payment status webhook. See Section 3 (Third-Party Services).
- Billing audit log — every plan change, custom-rate override, refund, or admin intervention is appended to billing_audit_log/{eventId} for our own books and DPDPA accountability.
Admin / staff access:
A small number of ShareLync staff hold admin privileges (the admin_users allowlist). Admins can: (a) provision a new Hub Owner account by minting a one-time claim link, (b) view billing state and invoice history, (c) suspend or revoke a Hub Owner, (d) edit a Hub Owner's profile fields on their behalf during a support call. Every admin write is recorded in the audit log with the admin's UID. Admins cannot read your members' encrypted biodatas — the encryption keys live with the members, not on our servers.
Retention period for Hub Owner data:
- While your account is active — for as long as you remain a Hub Owner.
- After account closure — thirty (30) days for the substantive records (hub_owners profile, member roster, notes, pairings, share log, activity log, helper records), after which the substantive records are permanently erased. We retain billing records (invoices, payment status, billing audit log) for a longer period as required by applicable tax and accounting law — typically eight (8) years from the close of the financial year in which the transaction occurred — under DPDPA Section 8(7) legal-obligation basis.
- Consent records and audit-trail entries that demonstrate your members' affirmative consent to join your Hub are tombstoned (not hard-deleted) and retained for three (3) years from the date of revocation or hub closure, as audit evidence under DPDPA Section 11 read with the DPB Rules.
- Backup copies of erased data may persist in our or our Data Processors' encrypted backups for a maximum of ninety (90) days after the primary erasure, after which the backups are themselves overwritten or erased.
Your rights as a Hub Owner (DPDPA Sections 11–14):
- Right of access (Section 11). Email founders@sharelync.app with the subject “Data export request” from the contact address registered against your Hub Owner account. We will provide, in a structured, commonly used and machine-readable format (JSON), a copy of your hub_owners document, member roster, notes, pairings, share log, activity log, invoice history, and helper records, together with a summary of the categories of Personal Data we hold, the identities of Data Processors, and the purposes of processing. We aim to respond within seven (7) working days and in any event within thirty (30) days, subject to the verification of your identity as required under DPDPA Section 14.
- Right of erasure (Section 12). Email the same address with the subject “Delete my hub account”. We will: (a) erase the substantive Hub Owner records within thirty (30) days; (b) retain only the categories of data identified under “Retention period” above for the stated longer periods on the lawful basis identified for each; (c) tombstone consent records and audit-trail entries that we are required to preserve under DPDPA Section 11 read with the DPB Rules. Erasure of your Hub Owner account does not erase your members' own biodatas — those are personal data of the respective members held on their own ShareLync consumer accounts, in respect of which the members are the Data Principals. We will remove the bindings between your closed hub and each member, terminate any helper authorisations, and notify Razorpay to cancel future billing.
- Right of correction and completion (Section 12). Edit your Hub Owner profile fields at hub.sharelync.app/settings at any time; for fields that are not user-editable, write to founders@sharelync.app and we will action the correction within seven (7) working days.

We do not charge a fee for the exercise of these rights.

11. Children's Privacy (DPDPA Section 9)
ShareLync is intended exclusively for use by individuals who have attained the age of majority in their jurisdiction (in India, 18 years of age) for the purpose of creating, managing, and sharing personal biodatas in the context of arranged-marriage introductions. The terms of service prohibit individuals under 18 from creating an account or submitting any waitlist or contact form.
In accordance with DPDPA Section 9, we (i) do not knowingly collect Personal Data of any child (individual under 18); (ii) do not undertake tracking, behavioural monitoring, or targeted advertising directed at children; and (iii) do not undertake any processing of Personal Data of children that is likely to cause any detrimental effect on their well-being. Analytics collection is disabled for users self-declaring as under 18, in compliance with this section.
If we become aware that we have inadvertently collected Personal Data of an individual under 18 — including a report from a parent, guardian, or any other person — we will erase that Personal Data without undue delay and in any event within seven (7) working days, and will discontinue any further processing. Parents or guardians who believe their child has provided personal data should write to admin@sharelync.app identifying the account in question.

We may update this policy as our technology evolves or as required by law. Significant changes will be notified via:
- In-app notification

Continued use of the service after changes implies acceptance of the updated terms.

15. Security Incident & Breach Notification (DPDPA Section 8(6))
ShareLync maintains a written incident-response procedure to identify, contain, investigate, and remediate any “personal data breach” as that term is defined under DPDPA Section 2(t) (any unauthorised processing of Personal Data, or accidental disclosure, acquisition, sharing, use, alteration, destruction or loss of access to Personal Data, that compromises the confidentiality, integrity, or availability of Personal Data).
In the event of a personal data breach, we will:
- Notify the Data Protection Board in the form and manner prescribed by the DPB Rules, within the timeline so prescribed.
- Notify each affected Data Principal in the form and manner prescribed by the DPB Rules, providing a description of the breach, the categories of Personal Data affected, the likely consequences, the measures taken or proposed to address the breach, and the contact details of the Grievance Officer.
- Implement remedial measures to mitigate the consequences of the breach and to prevent recurrence, including, where appropriate, the rotation of compromised secrets, the revocation of compromised authentication tokens, and the strengthening of security controls.
- Maintain a written record of the breach and the response, for at least three (3) years.
Security incidents may be reported to admin@sharelync.app with the subject line “Security incident report”. We welcome responsible disclosure from security researchers and will acknowledge receipt within 72 hours.
16. Cross-Border Data Transfer (DPDPA Section 16)
ShareLync is operated from India and the principal site of storage for Personal Data is Google Cloud's Indian multi-region. However, certain Personal Data is necessarily transferred to and processed in jurisdictions outside India by the Data Processors listed below. The Central Government has not, as of the “Last Updated” date above, exercised its power under DPDPA Section 16 to restrict the transfer of Personal Data to any specific country or territory. The following is a consolidated list of the countries and entities to which Personal Data is transferred and the safeguards on which we rely:
- Google LLC / Google Cloud / Firebase (United States; processing occurs in multi-region storage including India, the United States, and the European Union depending on the service). Safeguard: the data-processing addendum that forms part of the Google Cloud Terms of Service, supplemented by Google's Standard Contractual Clauses for international transfers; Google's certifications under ISO/IEC 27001, 27017, 27018, SOC 1/2/3, and the EU–US Data Privacy Framework.
- Meta Platforms, Inc. (United States and Ireland; WhatsApp Business Cloud API processing). Safeguard: the WhatsApp Business Solution Terms incorporated by reference at the time of API integration; Meta's certification under the EU–US Data Privacy Framework and the UK and Swiss extensions thereof.
- Google Gemini API (United States, processing of biodata documents during AI extraction). Safeguard: the Gemini API Additional Terms of Service which expressly prohibit the use of submitted content for training Google's AI models. Documents are deleted from our temporary storage within 30 seconds of processing.
- Apple Inc. (United States; only where you choose Sign in with Apple). Safeguard: Apple's data-processing terms applicable to Sign in with Apple integrators.
- Razorpay Software Private Limited (India). Safeguard: domestic transfer; Razorpay is a payment aggregator authorised by the Reserve Bank of India, governed by the RBI Master Direction on Payment Aggregators and Payment Gateways, and certified under the Payment Card Industry Data Security Standard (PCI-DSS Level 1).
In each case, the transfer is necessary for the provision of the service or the performance of your contract with us. Where the Data Processor is located outside India, ShareLync has entered into data-processing terms that require the Data Processor to process the Personal Data only on documented instructions of ShareLync, to maintain confidentiality, to implement appropriate technical and organisational security measures, to assist us in responding to Data Principal rights requests, to notify us of personal data breaches without undue delay, and to delete or return Personal Data on termination of services.
If the Central Government, by notification under DPDPA Section 16, restricts the transfer of Personal Data to any country or territory in which one of the above Data Processors operates, we will reassess and, where necessary, terminate the relevant processing arrangement or transition to an alternative provider located in an unrestricted territory.
17. Governing Law, Jurisdiction & Severability
This Privacy Policy is governed by, and shall be construed in accordance with, the laws of the Republic of India, including (without limitation) the Digital Personal Data Protection Act, 2023, the Information Technology Act, 2000 and the rules made thereunder, and the rules notified by the Data Protection Board under the DPDPA. Any dispute, controversy, or claim arising out of or relating to this Privacy Policy, or to the processing of Personal Data by ShareLync, shall be subject to the exclusive jurisdiction of the courts at Bengaluru, Karnataka, India; provided that nothing in this clause shall preclude a Data Principal from exercising the statutory right to complain to the Data Protection Board of India or any other competent regulatory authority.
If any provision of this Privacy Policy is found by a court or other competent authority to be invalid, unlawful, or unenforceable in whole or in part, that provision shall be deemed severed from this Privacy Policy and the remaining provisions shall continue in full force and effect.
No failure or delay by ShareLync in exercising any right under this Privacy Policy or under the DPDPA shall operate as a waiver of that right, nor shall any single or partial exercise of any right preclude any further exercise of it.
