Surechart Support

Where is my data? On your device only. Surechart has no account and no server. Use Settings › Your data to export a CSV or create an encrypted backup file, and keep that file somewhere safe. Export is free, subscription or not.

Moving to a new phone. Create an encrypted backup on the old phone, save the file (Files, AirDrop or any cloud drive you trust), then restore it in Surechart on the new phone with the same passphrase. Apple's device backup also carries the record across when you restore the whole phone.

Apple Health. Surechart only reads sleep, resting heart rate and steps, and only if you turn it on. Change access any time in the Health app under Sharing › Apps.

Reminders did not arrive. Check that notifications are allowed for Surechart in iOS Settings, that a Focus mode is not silencing them, and that the daily check-in time in Settings is what you expect.

Subscriptions and refunds. Subscriptions are managed in your Apple ID settings. Refunds are handled by Apple at reportaproblem.apple.com. Restore purchases is in Settings › Premium.

Medical questions. Surechart cannot answer them. It records what you enter and does not give medical advice, calculate doses or interpret results. Please talk to your clinician.
