Privacy Policy

Last updated: July 24, 2026

MemoryLens 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 features work locally on your device. Your purchase status only — all photo and face data stays on-device. Purchases are managed anonymously via RevenueCat — no personal account is needed.

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.
  • Photo & face data — stored locally on-device only, never uploaded.

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 app storage.
  • Photo metadata beyond what you explicitly share.
  • Analytics on photo contents, people detected, or your search queries.
  • Your email address or any personal identifiers — except for participants in our invite-only Founding Tester programme, described below.

We do not collect your email address, photos, or any biometric data on our servers, other than as described for the Founding Tester programme below.

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 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.

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 and are never transmitted to our servers or any third party.

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.

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. To request deletion of any purchase data or Founding Tester email we hold, email memorylens.support@gmail.com.

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.

India — DPDP Act compliance

We process personal data in accordance with India's Digital Personal Data Protection Act 2023. You have the right to access, correct, and erase your personal data by contacting 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.
