CoreSupport
Questions, problems or ideas: write to corefast.support@icloud.com.
Is CoreFast free?
Yes. There are no ads and no in-app purchases.
Do I need an account?
No. There is nothing to sign up for or sign in to.
Where is my data kept?
On your phone, stored encrypted. CoreFast has no server holding your fasting history or health readings. See the privacy policy for the few optional exceptions, such as Circles and Local weather.
How do I move to a new phone?
In Settings, export a backup file and keep it somewhere safe (Files, iCloud Drive, Google Drive or email it to yourself). On the new phone, install CoreFast and import that file in Settings. Without a backup file, your history can't be recovered, because it was never stored anywhere else.
How do I delete my data?
Settings › Delete all local data removes everything from your phone and, if you're in Circles, tells your circles you left.
Does CoreFast work with Apple Health or Health Connect?
Yes, if you turn it on. CoreFast only reads (sleep, steps, active energy, resting heart rate, HRV, glucose, and weight if you choose), and it never writes to them.
Is CoreFast medical advice?
No. It's a tracking tool for general wellness. Talk to your clinician before you start fasting, especially if you're pregnant, take medicines for diabetes, or have a history of disordered eating.
Something isn't working.
Email corefast.support@icloud.com with your phone model, the app version (Settings › About) and what happened. We read every message.
