What stays on your Mac
Everything the app makes or remembers lives on your machine, in places you can see and control:
- Recordings and photos go to folders you choose, as ordinary files. Move them, rename them, delete them — the app has no hidden copy.
- Settings (your chosen folders, sort orders, appearance) are stored in the app's macOS preferences, on this Mac.
- Take marks, edits and photo treatments are saved on your Mac so they survive quitting the app. Nowhere else.
What leaves your Mac
Nothing. The app has no upload, no sign-in and no account with anyone. Your footage stays on your Mac until you move it yourself, and it never talks to the internet at all.
The one network thing it can do is optional and local: if you switch on the iPhone remote in Settings, the Mac listens on your own Wi-Fi for your phone, and the camera's controls and live picture travel between the two over that network. Nothing goes beyond it, and the switch is off until you turn it on.
What we never see
We have no servers, so no data of yours can reach us. We don't know that you installed the app, what you shot, where it went, or that you exist — and we like it that way. There is nothing for us to lose, leak, sell, or be subpoenaed for.
This website
This site is plain, static pages. No cookies, no analytics, no tracking pixels, no forms. Your visit here is not recorded by us.
Permissions the app asks for
macOS will ask on the app's behalf for the microphone (only if you record sound, only for the length of a take) and the camera (for webcam preview). Saying no never breaks the rest of the app. These are standard macOS permissions you can change any time in System Settings.
Changes
If this policy ever changes, the change and its date will be posted on this page. Since the app collects nothing, the realistic direction of change is "still nothing".

To delete everything Tether knows about you: delete the app. That is the whole procedure, because Tether stores nothing on any server — there is nowhere else for your data to be.
