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.
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.
Some clinical links open trusted external sites (mayoclinic.org, fda.gov). Those sites have their own privacy policies.
You can delete every trace of your data at any time using the button below. This clears all Blu Harmony keys from this browser instantly.
Removes every Blu Harmony entry from this browser. Cannot be undone.
