Privacy Policy

Last updated: July 17, 2026

Blu Harmony is designed to work without an account. In the free tier, every input — your goals, medications, allergies, hydration logs, mood check-ins, habits, and feedback — is stored only in your browser's local storage on this device.

What we store on your device

  • Goal selections, entered supplements and medications, allergies
  • Daily hydration, mood, and habit logs
  • Feedback you submit through the Reset tab
  • Waitlist emails you enter (until the waitlist API opens)
  • A flag remembering whether you've seen the welcome screen

What we send off-device

Nothing that identifies you. The app does not require sign-in, does not sync your data to a server, and does not sell information. Anonymous errors may be reported to help us fix bugs.

Third-party services

Some clinical links open trusted external sites (mayoclinic.org, fda.gov). Those sites have their own privacy policies.

Your rights
