Privacy policy
Last updated: October 28, 2026
This policy explains what GoodFat does with your information. We wrote it in plain language so you can understand it.
1. The short version
- Meal photos stay on your iPhone. Apple Intelligence and Apple’s Vision framework read the photo on the device. GoodFat does not upload it and does not keep a photo library of your meals.
- We do not sell your data. We do not share your food log or profile with advertisers or data brokers.
- We use a few service partners only to run the account, the synced food log, and paywalls. Meal photos and questions are handled on the iPhone. Details are below.
- You can delete your account anytime in Settings.
2. Who we are
GoodFat (“we,” “us”) is the GoodFat mobile app and website at goodfatbadfat.com. Questions: [email protected].
3. Food photos (important)
When you take or pick a meal photo, GoodFat reads it on the iPhone. Apple’s Vision framework looks for a barcode or label text. Apple Intelligence names the food. Both run on the device.
We do not upload your food photos. We do not store them in your food log, and we do not keep a photo album on our servers. The photo is not sent to GoodFat or to a cloud model such as Google Gemini.
Questions you type in Ask are handled the same way: Apple Intelligence on the iPhone, then a lookup in the nutrition catalog stored on the phone. If the catalog is missing a fatty acid, GoodFat does not fill it in from a cloud model.
4. What we collect
Account
GoodFat can run with an anonymous account so you do not need an email to start. If you add a name or email in your profile, we store those fields with your account id.
Food log
Foods you confirm (name, amount, nutrition fields, inflammatory score, and related details such as barcode or source). This is how your Today / Weekly / Monthly views work.
Chat
Questions and replies in Ask stay on the iPhone. GoodFat does not send that conversation to a cloud model, and we do not keep a server log of those messages.
On-device nutrition pack
A large US food catalog (sourced from public data such as USDA and Open Food Facts) lives on your phone. Lookups can happen without sending the whole catalog to us.
Subscriptions
If you subscribe, purchase status may be synced so Premium features unlock. See section 6.
5. How we use information
- To identify foods and show nutrition and score estimates
- To keep your food log and trends
- To answer questions on your iPhone with Apple Intelligence
- To unlock paid features you buy
- To secure the service and fix bugs
- To respond if you contact support
We do not use your food log to sell ads. We do not sell personal information.
6. Sharing — and what we do not share
We do not sell or rent your personal information to third parties.We do not share your user profile or food log with other companies for their own marketing.
To run GoodFat we use a small set of processors that only get what they need to do their job:
- Supabase — account auth, database, and secure edge functions
- Apple — Apple Intelligence and Vision run on your iPhone for meal photos and Ask. App Store billing applies when you buy Premium. Apple’s own terms cover on-device system features.
- RevenueCat — subscription status sync for Premium access
We may also share information if the law requires it, or to protect people from serious harm or fraud.
7. Where data lives
Meal photos and Ask stay on the iPhone. The nutrition pack is stored on the device. A copy of the food log also stays on the phone. If you have an account session, confirmed log entries (name, amount, nutrition fields, and score — not the photo) may sync to our cloud provider (Supabase).
8. Keeping data
- Photos: processed on the iPhone and not uploaded to GoodFat.
- Food log and account: kept on the phone, and in the cloud while your account exists.
- Ask: stays on the iPhone. We do not keep a server copy of those messages.
9. Your choices
- You can use Ask without attaching a photo. Ask still runs on the iPhone.
- You can edit or remove foods from your log in the app.
- Delete account in Settings removes your auth user and related cloud rows we control. Local copies on that phone are cleared when you delete the app.
For privacy requests, email [email protected].
10. Children
GoodFat is not directed at children under 13 (or the minimum age in your country). Do not use the app if you are under that age.
11. Security
We use standard industry protections (including encrypted connections). No method of storage or transfer is 100% safe, so please use a device you trust.
12. Changes
If we update this policy, we will change the “Last updated” date on this page. Big changes may also be noted in the app.
13. Contact
Email [email protected]. See also our Terms of use.
15. Website contact form
The support form checks the fields in your browser, then opens your email app with a draft to [email protected]. The public website does not store that form. We receive the message only if you send the email. We do not use it to market to you.
