Food at Peace ("the app", "we") is a calorie and nutrition tracker for iPhone. This policy explains what data the app handles and where it goes. The short version: your data stays on your device by default. If you choose to sign in, your food log and profile sync through our server so they follow you across devices. The app has no advertising and no analytics or tracking SDKs.
The app stores the following locally on your iPhone (in the app's private storage):
If you never sign in, none of this leaves your device, and you can erase all of it by deleting the app.
Signing in is optional — every feature works without it. If you sign in with Apple to enable cross-device sync:
If you grant permission, the app reads from Apple Health: active and basal energy burned, body weight, height, date of birth (to derive your age), biological sex, and workouts (this includes Garmin and other data that flows into Apple Health). These power your calorie budget and targets. With permission, the app also writes back the food you log (calories, protein, saturated fat) and any weight or height you edit.
Health data is read and written on your device. We do not receive raw HealthKit data on our servers. If you enable the optional sync above, the profile values shown in the app (e.g. weight, height, age, sex) are included in your synced profile; nothing else from Apple Health is transmitted. Health data is never used for advertising or shared with third parties. Your use of Apple Health is also governed by Apple's Privacy Policy.
The Today screen can show your local weather. If you allow location access, your approximate coordinates are sent to the Open-Meteo weather service to fetch current conditions. If you decline, the app may instead use an approximate, city-level location derived from your IP address (via ipapi.co). Your location is used only to display the weather — it is not stored by us, not linked to your identity, and not used for any other purpose. You can decline location access and the app works normally.
The optional "analyze a photo" feature lets you take or choose a photo of a meal. When you use it, that single photo is sent over an encrypted (HTTPS) connection through our server to the Anthropic (Claude) API, which estimates the meal's calories, protein, and saturated fat. The estimate is returned to your device for you to confirm before logging.
If you use the in-app feedback form, the message you type is submitted to a Google Form so we can read it. Only what you write is sent — providing an email is optional and used only to reply to you. Don't include sensitive information in feedback messages.
The app's calorie, protein, and saturated-fat figures are general estimates for healthy adults, based on published formulas and guidelines (see the in-app "Sources & methodology" screen). They are not medical advice. Consult a doctor or registered dietitian before making significant dietary changes.
The app is not directed to children under 13 and does not knowingly collect information from them.
We may update this policy as the app evolves. Material changes will be reflected by updating the "Last updated" date above.
