Data & privacy

Privacy

Everything you enter stays on this device, in this browser. Nothing is sent to a server, except feedback you choose to send and the optional background alarm described below.

There is no account, no tracking and no cookies. The app uses the browser's local storage so your entries are still here next time.

You can export your data or delete it at any time. Clearing the browser's site data also removes it.

Background alarm (optional): if you allow notifications and start the purge timer, your browser's push address and the time the timer ends are sent to this app's server and to its scheduling service (Upstash) so the alarm can reach you with the app closed. No name, account or pipe data is included. Stopping the timer cancels it; the data is not kept after the alarm has been sent.

Calendar notes can contain personal information. Anyone who can use this browser profile can read them.

Offline mode & updates

Save the app on this device so it opens and works without an internet connection, for example from your home screen. Your entries already stay on the device.

Tip: add PipeCalc to your home screen first (iPhone: Share, then Add to Home Screen).
