Effective September 9, 2026
Your data stays on your device
Momentum does not currently require an account, use analytics, or send your focus history to a server. Timer data, completed sessions, and preferences are stored locally by your browser.
Notifications and sounds
If you allow notifications, your browser and operating system deliver them. Momentum uses the permission only for timer reminders. Built-in sounds are loaded from the same site as the app.
Deleting your data
You can remove Momentum's local information by clearing this site's browser data. Clearing browser storage or uninstalling the web app may also remove your history and settings.
Future changes
If Momentum later adds accounts, cloud sync, payments, or analytics, this policy will be updated before those features collect data. Momentum is a productivity tool, not a medical service, and you should not enter sensitive health information into it.
