Questions, problems or feedback about Fatlow? Email us.
It helps if you tell us your iPhone model, your iOS version, and whether you signed in with Apple or Google.
How do I delete my account?
In the app, go to Profile > Account > Delete account. This erases your account and all linked data from our database immediately. Copies in our backups roll off within 30 days.
You can also email us and ask us to delete it.
Deleting your account does not cancel a subscription. Cancel it first, as shown below.
How do I cancel my subscription?
Subscriptions are handled by Apple. On your iPhone, open Settings > Apple ID > Subscriptions, choose Fatlow and cancel.
If you are on a free trial and do not want to be charged, cancel at least 24 hours before the trial ends.
How do I get a refund?
Refunds for App Store purchases are handled by Apple, so please request one from Apple. We cannot issue refunds ourselves.
How do I restore my purchases?
If you reinstall Fatlow or move to a new iPhone, make sure you are signed in with the same Apple ID you used to buy, then tap Restore at the bottom of the plan screen in the app.
What does Fatlow read from Apple Health?
With your permission, Fatlow reads steps, active energy, resting (basal) energy, workouts, sleep, weight, height, date of birth and biological sex. It only reads. It never writes anything to Apple Health.
We use this data to estimate your daily energy burn and fat change, and we show it to the in-app coach. It is never used for advertising or marketing and never sold.
To turn access off, go to iOS Settings > Health > Data Access & Devices.
How does the coach work? Is my data sent to AI?
The coach and food reading run on Claude models from Anthropic. To read your food and write the coach's replies, we send Anthropic your messages, food photos, safety answers and figures derived from Apple Health.
The app asks for your permission before the first time it uses AI. You can withdraw it at any time in the Profile, and AI features then stop.
We do not use your data to train AI models ourselves. Anthropic processes it to provide the service, under its own terms. More in our Privacy Policy.
Is Fatlow medical advice?
No. Fatlow gives general wellness estimates: calorie burn from Apple Health, intake from what you log, and fat change as your calorie deficit divided by 7.7 kcal per gram of fat. These estimates can be wrong.
Talk to a doctor before you change your diet, especially if you are pregnant, have a medical condition, or have a history of an eating disorder.
Can I get a copy of my data?
Yes. Email us and ask for an export.
