Privacy

Focus25 has no accounts and no database. Here is everything it does with data.

Stored in your browser

Your timer settings, tasks, running-timer state and session history are saved in your browser’s localStorage so they survive a page reload. They never leave your device, and they are not visible to us. Clearing your browser data removes them, or use the button below.

AI study planner

If you press “Make my plan” on the study timer, the text you typed and your chosen time and rhythm are sent to our server and passed to a language model through Vercel AI Gateway to write the plan. We don’t store the text or the plan. The planner is never called unless you press the button. Don’t type anything personal into it.

Analytics

We use Ahrefs Web Analytics to count page views. It is cookieless and doesn’t track you across sites.

Notifications and sound

Desktop notifications are only shown if you grant permission. The chime is generated in your browser; no audio is downloaded or recorded.
