Loggr stores the data you add or connect: weights, GLP-1 logs, check-ins, notes, reminders, settings, share-card choices, and progress photo metadata.
Progress photos are stored in a private Backblaze B2 bucket with server-side encryption enabled. The app displays them through short-lived private links.
Public share cards are opt-in. They only show the fields you choose. Your email, photos, detailed weigh-in history, notes, and check-ins are not included on public share cards.
We do not sell user data. You can export CSV files from the Data page and delete scoped data or your full account from Settings.
No health app can honestly promise zero risk. Loggr uses private storage, account sessions, and scoped deletion controls to reduce exposure. Use a unique password.
