Lightbrary collects nothing, sends nothing and has no server to send anything to.
None. There is no account, no sign-in, no analytics, no crash reporting service, no advertising identifier and no tracking of any kind. The app makes no network requests of its own, with a single exception you control: choosing Check for Updates… from the menu fetches a small file listing the current version number. Nothing is sent about you or your library, and it happens only when you ask for it — never on launch, never in the background.
The app asks for access to your photo library so it can show you your photos. That is the whole reason. Photos are read on the device and never uploaded anywhere by this app.
On macOS the app can additionally read the analysis data the operating system has already computed for your own library — measures such as sharpness, exposure, detected faces and recognised screenshots. This requires Full Disk Access, which you grant yourself in System Settings. That data is read only; the app never writes to the system photo databases.
Ratings, deletion marks and the imported measures are stored in a database inside the app’s own container on your device.
If you turn on syncing between your devices, that data — not your photos — is written to a single file in a folder you pick yourself. If you pick a folder inside iCloud Drive, Google Drive or OneDrive, then that provider’s own privacy policy applies to the file while it sits there. The app has no access to any of those services beyond writing and reading that one file, and no copy is kept anywhere else.
Deletion goes through the system photo library, so the system asks for confirmation and deleted photos land in Recently Deleted, where they can be recovered for 30 days.
The app is not directed at children and collects no data from anyone.
If this policy ever changes, the new version will appear at this address.
