Privacy Policy

Last updated: 24 August 2026

The short version:
LensMind runs entirely on your iPhone. It collects nothing about you and uploads none of your photos.

1. Fully on-device, no servers

LensMind runs entirely on your iPhone. All detection, classification, search and statistics happen locally on your device. We operate no servers and expose no endpoints that could receive your photos or analysis results.

Concretely: the app contains no networking code (no URLSession, no Network framework, no sockets). This is checked by an automated test on every build, so it is not a promise — it is a verifiable fact.

2. Permissions we request

  • Photo Library (read) — to clean, analyze and search your photos. Both “Full Access” and “Selected Photos” work.
  • Photo Library (write) — to save compressed media back, add photos to albums, and perform deletions.

Deletions go through the iOS system confirmation dialog and land in Recently Deleted, recoverable for 30 days. The app never bypasses that dialog.

3. What we never do

  • Never upload your photos or thumbnails anywhere
  • Never make any network request
  • Never use third-party analytics, advertising or tracking SDKs
  • Never collect personal information, location, or device identifiers
  • Never require registration or sign-in — there is no account system
  • Never share data with third parties (no data leaves your device to begin with)

4. Where data is stored

Analysis results (hashes, image feature vectors, capture metadata, category labels, scan progress) are stored in a local database inside the app sandbox. Deleting the app removes all of it.

5. Semantic search model

Search uses Apple’s MobileCLIP-S2 Core ML model. It ships inside the app (the main reason the download is ~190 MB) and runs inference entirely on your device, with no network calls.

6. Diagnostics and problem reports

The app keeps a local run log (capped at 8 MB, rolling) so that problems can be diagnosed when you choose to report them. This log is never uploaded automatically. It leaves your device only if you pick a destination yourself in Settings → Help & Feedback → Report a problem.

Included

Run log, app version, device model, iOS version, photo count, free storage, scan progress

Not included

Photos, thumbnails, file names, album names, search terms, location data

7. About this website

To be scrupulous about the “no tracking” claim above, here is how the site itself works: lensmind.ronn.fun is hosted on Vercel with Vercel’s built-in aggregate analytics (page views and load speed). It sets no cookies, does no cross-site tracking, and builds no user profiles. This site has no Google Analytics, Baidu Analytics, or ad scripts.

Website analytics are unrelated to the app — the app still makes no network requests.

8. Children’s privacy

This app is not directed to children under 13, and does not knowingly collect personal information from users of any age.
