Your data
is yours.

The Parabellum Program stores everything locally on your device using your browser’s storage. No account, no cloud, no tracking.

What's stored

The tools you enable, your accent colors, and the entries you log live in local storage on your device only.

MARK and your key

If you enable MARK with your own Anthropic API key, that key is stored on your device and used to call Claude directly. If you use a proxy instead, the key lives in your own server, never ours.

What leaves your device

Nothing automatically. Messages you send to MARK go to Anthropic’s API to generate a reply. A workout graphic is shared only where you choose to send it.

Clearing data

Use “Reset all data” in Settings, or clear your browser/app storage, to erase everything permanently.
