Data Storage
We prioritize your privacy. FastSlow is a local-first application. We do not store your routines, session history, or settings on our servers. All data is stored locally on your device using LocalStorage.
Third-Party Services
We integrate with YouTube for music playback. By using this feature, you agree to be bound by the YouTube Terms of Service and acknowledge that your use is subject to Google's Privacy Policy.
Cookies & Analytics
We use minimal local storage to remember your theme preference and routine data.
We use PostHog to collect anonymous usage data to help us improve the application. This is configured in "cookieless mode", which means meaningful usage data is collected without placing tracking cookies on your device.
