Privacy policy
JemRec has no servers, no accounts, and no analytics. Nothing it records or reads ever leaves your phone.
Last updated: September 2026.
What it collects
Nothing is sent anywhere. There is no backend to send it to. The developer cannot see your recordings, your contacts, your call history, or that you use the app at all.
What stays on the phone
| Data | Where it lives |
|---|---|
| Call recordings | The phone’s Recordings/JemRec folder, or a folder you
choose. Yours to play, share, move or delete like any other file. |
| Contact names and photos | Read from the phone’s own call log and contacts, only if you allow it, and only to label a recording. Nothing is copied or stored; the lookup happens each time the list is shown. |
| Settings | The app’s own private storage: whether recording is on, whether to ask before each call, where to save, and a random token the app uses to talk to its own recorder. |
Network use
The app holds the INTERNET permission and uses no network. Android
requires that permission for any TCP socket, including one to
127.0.0.1, and the app’s two sockets are both to the phone
itself: pairing with the phone’s own Wireless debugging during setup, and
talking to its recorder afterwards. Neither reaches your router, let alone the
internet.
This website
Static files served by GitHub Pages, with no analytics, no cookies, and no fonts or scripts fetched from anywhere else. The one thing it stores is whether you chose light or dark, in your own browser, where it stays.
The microphone
The app holds no microphone permission and opens no audio device. Calls are captured by a separate shell-privileged process, which the app starts during setup and which writes to a file the app collects afterwards.
Deleting your data
Delete individual recordings in the app, or the whole folder from any file manager. Start fresh in Settings undoes the setup and hands the permissions back, and deliberately keeps your recordings. Uninstalling the app removes the app and its settings; the recordings stay, because they are yours and are not the app’s to take.
Children
The app is not directed at children and collects nothing from anyone.
Changes
If this policy ever changes it changes in the open, in the same repository as the code, with the change visible in the history.
