Privacy Policy

Effective date: 15 November 2026

ZetCut ("the app") is made by an independent developer ("I", "me"), who you can reach at the email at the end of this page. This policy explains what happens to your information when you use ZetCut on Android.

Videos you choose

You choose which videos ZetCut opens, either through Android's gallery picker or by sharing a video to ZetCut.

When you tap "Select videos", ZetCut asks for permission to access your videos. It uses this only to read the name and folder of the videos you pick, so the trimmed video can be saved next to the original under a matching name. You can choose "Allow limited access" to share only some videos, or decline. ZetCut still works without it, and then saves cuts to a ZetCut album. ZetCut doesn't access your photos, and you can change this permission at any time in Android settings.

The app reads the videos you pick on your phone to find your training sets. To do this it detects body position (pose landmarks) in sampled frames. The pose data is used only on your phone, only to work out where to cut, and is never uploaded.

New videos you save are written to your phone's gallery, in the folder you choose in Settings. If you ask ZetCut to delete the originals, Android asks you to confirm first.

Information stored on your phone

ZetCut keeps a small amount of information in its own private storage on your phone:

• your settings, for example how many seconds to keep before and after a set, and where to save
• the cut points for videos you've opened, so you can reopen and adjust a cut
• the date you first opened the app

This stays on your device. If Android's own backup is turned on for your phone, Android may include it in your Google backup, under Google's control and your Google account settings.

Notifications

ZetCut can show notifications for progress and when your videos are ready. These are created on your phone, and you can turn them off in Android settings.

Data shared with others

None. ZetCut doesn't send your data to me or to anyone else.

Security

ZetCut has no servers and doesn't send anything over the internet, so your videos and data are never exposed in transit or stored by anyone else. All processing happens on your phone. The information listed above is kept in the app's private storage, which Android protects so that other apps can't read it. Videos you save go to your gallery like any other video you record.

Keeping and deleting your data

ZetCut keeps its stored information on your phone only for as long as the app is installed. Pose data used to find your sets is only kept while it's needed for the cut. I don't hold any of your data, so there is nothing on my side to delete.

You can delete everything ZetCut has stored at any time by uninstalling the app, or in Android Settings → Apps → ZetCut → Storage → Clear storage. Videos ZetCut saved stay in your gallery until you delete them, like your other videos.

Children

ZetCut isn't aimed at children under 13.

Changes

If this policy changes, the new version will be posted on this page with a new effective date.
