Where your data lives
Your diary is stored on your device first and synced to your Gravl account — that's what makes offline logging and multi-device use work. Weight, measurements, and progress photos are shared with Gravl Workouts under the same account. You can download a copy of your whole history at any time — see Export your data.
What the AI features send
AI features send exactly what they need to produce your result, and nothing runs in the background on its own:
- Photo logging uploads the meal photo you took, which is also kept attached to your diary entry.
- Voice logging sends the transcript text — your phone's built-in speech recognition converts the audio, and the app never receives or uploads the recording itself.
- Label scanning sends the label photo; recipe imports send the photos, text, or link you provided.
- The coach cards send a compact numeric summary (targets, expenditure, trend) — never your diary, meal photos, weigh-ins, or identity.
Everything else — your targets math, trend weight, expenditure — is computed without AI involvement.
What the app doesn't do
- No ads, and no advertising SDKs.
- No third-party analytics tracking your behavior.
- Crash reporting is technical and scrubbed: a report identifies the error and the account it happened on, so it can be traced and answered if you write in — never your email or your network addresses, which are stripped before anything is sent.
- A food you create by hand is private, and cannot be contributed to the catalog at all. A food you build by scanning a barcoded label is the exception: it arrives with Contribute to the catalog already on, because the barcode and the label are what make a submission checkable. You can switch it off on that screen, and turn it off later by editing the food. Either way, contributing shares the food's information — name, brand, barcode, nutrition — never anything about you.
