Focus Cycle Timer does not collect, transmit or sell any data.
No analytics, telemetry or tracking of any kind.
No network requests are ever made. The extension works fully offline.
No remote code is loaded; everything that runs is bundled in the package you installed.
Your settings (work and break durations, cycle count, sound preference) and your session history are stored only in your browser's local extension storage, on your own device. Nothing is sent anywhere and nothing syncs to any server we operate, because we do not operate one.
alarms: to end work sessions and breaks on time, even if the extension's background process has been unloaded.
notifications: to show a system notification when a session or break ends.
storage: to save your settings and session history locally.
offscreen: to play the optional end-of-session chime (a technical requirement of Manifest V3, which does not allow the background service worker to play audio directly).
The extension has no access to any website. It cannot read or modify the content of any page you visit.
Uninstalling the extension, or clearing its storage from chrome://extensions, permanently deletes all locally stored settings and history. There is nothing to delete on our end, because nothing ever left your device.
