Frequently asked questions
Can I keep my data when I switch or reinstall?
Yes. When you sign in with Apple or Google, your profile and daily records (check-ins and commits, and the streak, XP, and badges derived from them) are backed up to the cloud, so you can restore them on another device or after reinstalling with the same account. Signing in is optional.
How do I delete my account or data?
You can request account deletion from the app’s Settings. Deleting removes your profile and records from the cloud. See the Privacy Policy for details.
How is my step / health data handled?
Step and other device-sensor health data read from Apple Health / Health Connect never leave your device. They are used on-device for display only. See the Privacy Policy for details.
What are the weight, BMI, and estimated body-fat numbers based on?
These are general guides for tracking, not a medical diagnosis or advice. The in-app “weight trend” screen also links to the sources. The formulas are based on:
- BMI definition: World Health Organization (WHO) — Obesity and overweight (WHO)
- Estimated body-fat formula: Deurenberg P, Weststrate JA, Seidell JC (1991) — PubMed
Does it cost anything?
The current version is free to use. There are no in-app purchases.
