Data And Privacy

Slowdown collects sensitive-feeling personal state data even if it is not clinical data. Treat it seriously.

Best default:

• store on device first;
• do not require login;
• do not sync unless the user opts in;
• do not run third-party product analytics on personal state fields;
• make delete/export easy;
• explain what is stored in plain language.

Optional sync can be valuable for multi-device continuity, but it creates more responsibility. If Firebase sync is enabled, the app should document:

• what is synced;
• who can access it;
• whether data is encrypted in transit and at rest;
• how account deletion works;
• how to disable sync;
• what remains local.

For FreeIdeaStore validation, the privacy promise is part of the product, not a footnote.
