How your data is stored
localStorage (this device only)
There is currently no account or login. Every timer you start with "GO!" is saved to your browser's localStorage under "History", purely so you can find and re-run it later. This data stays on this device and this browser — it is not synced anywhere.
No tracking or ads
This app does not use cookies for tracking or analytics, and no external service is contacted. Your data is never sold or shared with third parties.
Your rights
You can clear your history at any time using the "Clear history" button on the History tab, or by clearing this site's data in your browser settings.
