BeanTrack — Privacy Policy

Last updated: August 27, 2026

BeanTrack is a one-person coffee app: track your beans' resting, log brews, score cups.

This policy covers three things — what we store, where it lives, and who can see it.

Written plainly; you shouldn't need a lawyer to read it.

1. You don't have to sign up

Tap "Try it first" on the login screen and the app works with no account andnothing uploaded — beans, brews, scores and photos all stay on your phone (on iOS theyride along with your regular iCloud device backup, which we can't see).

An account only adds cloud sync. The app is complete without one; without it you

just can't sync across devices, see the same data on the web, or post in the community.

2. What we collect when you do sign up

What	Why	Where
Email or phone number	Sign-in and account recovery	Supabase (hosted database)
Password	Stored only as an irreversible hash — we never see the plaintext	same
Username, avatar, bio (optional)	Who you are in the community	same

Phone verification codes are sent via Alibaba Cloud SMS; email codes via QQ Mail's

SMTP. The codes themselves are not stored in the database.

3. The data you record

Beans, roast dates, brew parameters, scores, notes, photos, and — optionally — the

location and altitude of a brew.

Local mode: stays on your phone.
Cloud mode: stored on Supabase (database + object storage). The database usesrow-level security: every row is tied to your account id, and other users cannotread your data.
You can migrate either direction at any time under Settings → Where data is stored.

Location is opt-in per record: we read it once only when you tap "Get" on the
