Privacy Policy

Last updated: April 13, 2026

Lume is designed to be private by default. This page explains exactly what happens with your data when you use the app.

Short version

  • Lume does not send your photos, metadata, or usage anywhere. Ever.
  • Lume does not have servers, accounts, or cloud sync.
  • Lume does not use third-party analytics, crash reporting, advertising, or tracking SDKs.
  • Lume reads your photo library on-device only, with your explicit permission.

What Lume collects

Nothing — off your device. Lume has no backend. The app never transmits your photos, photo metadata, device identifiers, or any other personal data off your phone.

What Lume stores on your device

Lume keeps a local SQLite database on your phone containing:

  • References (local asset IDs) to photos in your iOS Photos library.
  • A "liked" flag and counter per photo.
  • Location and date metadata only when you explicitly enable location in settings, and only as cached values to make search faster.

You can wipe all of this at any time from Settings → Clear app data. Uninstalling Lume also removes everything.

Permissions Lume uses

  • Photo Library (read): required to show your photos. Lume uses Apple's native permission prompt. You can revoke access in the iOS Settings app at any time.
  • Photo Library Location metadata: optional. Only requested if you turn on location-aware search in Lume's settings.

Lume does not request, and does not have access to, the Camera, Microphone, Contacts, Location services, Notifications, or any other sensitive permission.

Third-party services

Lume does not integrate with any third-party SDK that transmits data. No Firebase, no Sentry, no Segment, no analytics providers, no ad networks.

Children's privacy

Lume is not directed at children under 13. Because Lume collects nothing, it poses no specific privacy risk to children beyond what iOS itself governs.

Changes to this policy

If Lume ever starts using any data beyond what's described here, this policy will be updated and the "Last updated" date bumped before the behavior ships. For material changes, I'll also note it in the app.
