Privacy Policy

MemoryLens is operated by EdgeMind AI, a trading name of Nirav Prajapati (sole proprietor) ("we", "us"). It is built on one founding principle: your photos and face data are yours alone.This policy explains exactly what we collect, what we don't, and how we protect you.

No account required

You can use MemoryLens without creating an account. All core features work locally on your device — your photos and face data never leave it. The only data we ever hold about a normal user is anonymous purchase status, managed via RevenueCat, so Pro features unlock correctly.

What we collect

• Purchase status — so Pro features unlock correctly on this device, managed via RevenueCat. No payment card data is stored by us.
• App preferences — theme, scan settings, and other in-app choices, stored on your device.
• Photo & face data — stored locally on-device only, never uploaded.
• Founding Tester email — only if you join our invite-only Founding Tester programme (see below).
• Waitlist details— only if you sign up on our website (see "Website & waitlist" below).

What we never collect

• Your photos — they never leave your device.
• Face embeddings or biometric data — all AI processing runs on-device (TFLite on Android). Embeddings are stored only in your device's private, encrypted app storage.
• Analytics on photo contents, people detected, or your search queries.
• Your email address or any personal identifiers on our servers — except for the Founding Tester and waitlist cases described in this policy.

Photo metadata & location

When MemoryLens indexes your gallery, it reads photo metadata (EXIF), which can include the date a photo was taken and, if present, the GPS location embedded in the photo by your camera. This metadata is used only to organise and search your library and is stored only in your device's private, encrypted database. It is never uploaded to us or any third party. MemoryLens does not request the device location permission and does not track your live location.

On-device AI processing

Face detection, embedding computation, and clustering all run locally on your device. The 128-dimensional face vectors produced by our AI models are stored only in your device's private SQLite database (encrypted at rest) and are never transmitted to our servers or any third party.

Founding Tester programme

MemoryLens runs a limited, invite-only Founding Tester programme (Android only) that grants complimentary Pro access. If you choose to participate, we collect the email address you enter so we can send you a one-time verification code and confirm you're on the approved tester list. This email is stored in a dedicated Founding Tester record (via Supabase) and is not linked to any other app data. Participation is optional and entirely separate from normal use of the app or the Lifetime purchase.

Website & waitlist

If you join the waitlist on our website, we collect the email address you provide and any optional survey answers you choose to share (such as your device type, gallery size, photo categories, and what you'd like the app to solve). We use this to notify you about availability and to improve the product. This data is stored via Supabase and the confirmation email is sent via Resend. It is separate from the app and you can request its deletion at any time (see below).

Third-party services

• RevenueCat — manages in-app purchase entitlements. View their privacy policy at revenuecat.com/privacy.
• Google Play — handles payment processing. We do not receive your payment card details.
• Supabase — hosts our backend for the Founding Tester verification flow and website waitlist storage.
• Resend — sends transactional email (such as waitlist confirmations).
• Upstash — provides rate limiting on our web and verification endpoints, which processes your IP address to prevent abuse.
• Vercel Analytics & Speed Insights — collects aggregate, cookieless, non-identifying usage metrics on our website only (not in the app) to measure performance.

International data transfers

The limited server-side data described above (Founding Tester and waitlist emails, survey answers, and purchase records) is stored in our Supabase database, which is hosted in the European Union (West Europe region). Some supporting providers process data in other regions: Resend (transactional email) and Vercel (website hosting and aggregate analytics) process data in the United States, and Upstash (rate-limiting, which processes your IP address to prevent abuse) may process it outside your country. Where personal data is transferred internationally, we rely on the safeguards those providers offer (such as standard contractual clauses and their data-processing commitments). Your photos, face data, and embeddings are never transferred anywhere — they remain on your device.

Data retention and deletion

All photo data, face embeddings, and folder content exist only on your device and are removed when you uninstall the app. For the limited personal data we hold on our servers:

• Founding Tester email — retained for as long as the programme is active, and deleted within 30 days of a deletion request.
• Waitlist email and survey answers — retained until you unsubscribe or request deletion, and in any case no longer than 24 months after your last interaction.
• Purchase records — anonymous entitlement status is retained while the purchase is valid; deletion is subject to the records Google Play and RevenueCat keep under their own policies.

To request deletion of any purchase data, Founding Tester email, or waitlist data we hold, see our Delete Your Data page or email memorylens.support@gmail.com. We respond within 30 days.

Your rights

Depending on where you live, you have rights over the personal data we hold — including the right to access, correct, and erase it:

• European Union / EEA & UK (GDPR) — you may access, rectify, erase, restrict, or object to processing of your personal data, and request portability.
• India (DPDP Act 2023)— we process personal data in accordance with India's Digital Personal Data Protection Act 2023, and you may access, correct, and erase your personal data.
• Australia (Privacy Act 1988) — you may request access to and correction of the personal information we hold, consistent with the Australian Privacy Principles.

To exercise any of these rights, email memorylens.support@gmail.com. Because face embeddings never leave your device, there is no biometric data on our servers to export or erase.

Children's privacy

MemoryLens is not directed at children or users under the age of 18. We do not knowingly collect personal data from minors. If you believe a minor has used the app, please contact us at memorylens.support@gmail.com.

Changes to this policy

We will post material changes on our website at memorylensapp.com at least 14 days before they take effect. Continued use of the app after that date constitutes acceptance of the updated policy.
