Privacy Policy

Effective 20 July 2026

Cupbook is a coffee journal: you log and rate the coffees you drink. This policy explains what data the app handles and why. The short version: we collect only what the journal needs to work, we don't sell your data, and there are no ads.

What we collect

Account — your email address (or the identifier provided by Sign in with Apple / Google Sign-In) and a display name if you set one.
Your journal — the check-ins you create: ratings, tasting notes, brew details, and any photos you attach.
Scan photos — when you scan a coffee bag, the photo is sent to our server to recognize the label. Scan photos are used only for that recognition and are not stored; a photo is kept only if you attach it to a check-in yourself.
Catalog contributions — coffees you add to the shared catalog are visible to other users.
Diagnostics — basic crash and performance data, to keep the app working.

Where it lives

Your data is stored with Google Firebase (Google Cloud). Label recognition uses Anthropic's Claude API: the scan photo is processed to read the label and is not used to train AI models. These providers act as processors on our behalf; we don't share your data with anyone else, and we never sell it.

What other users see

Your check-ins are private to your account. Community ratings shown on a coffee are anonymous aggregates. Coffees you add to the catalog are public but are not attributed to you by name.

Deleting your data

Profile → Delete account removes your account and your check-ins, including photos. This is immediate and irreversible. Coffees you contributed to the shared catalog may remain, without any link to you.

Children

Cupbook is not directed at children under 13, and we do not knowingly collect their data.

Changes

If this policy changes, the current version will always be at this address, with the effective date above.
