Thirds privacy policy
Last updated November 1, 2026
Thirds collects no data. The app has no accounts, no analytics, no ads, no tracking and no network code. Your photos never leave your iPhone unless you save or share them yourself.
What stays on your phone
- Photos you take or import. Thirds keeps them, with your edit settings, in the app's own storage on your device. Deleting a photo in Thirds or deleting the app removes them.
- Photos you save. These go to your Photos library, and you control them there.
- Photos you share. The iOS share sheet sends them to the app or person you pick. Thirds never sees where they go.
Permissions
| Permission | Why Thirds asks |
|---|---|
| Camera | Shows the viewfinder and takes photos. Face detection for framing hints runs on the device and Thirds stores nothing from it. |
| Photo library (add only) | Saves your edited photos to Photos. |
| Photo library (read) | Opens a photo you pick in the system picker so you can edit it. Thirds only sees the photos you choose. |
| Motion | Reads the phone's tilt to show the level. Thirds stores nothing from it. |
You can turn any of these off in Settings → Thirds. The rest of the app keeps working.
Children
Thirds collects nothing from anyone, children included.
