Is my data really private?
Your health entries are stored on your device unless you choose to export them. Ondelle does not use health entries for advertising. Apple and RevenueCat process purchase information to verify Premium access. See our Privacy Policy for details.
How do I back up my data?
Open Ondelle's Settings and choose Backup & restore to export a copy of your data. You choose where to save it. Backups are not encrypted, so keep them private and save one outside the app before deleting it or changing phones.
How accurate are the predictions?
Predictions are estimates based on information you log. They may be inaccurate, do not confirm ovulation, and must not be used for contraception or medical decisions.
How do I restore a purchase?
Open Ondelle's Premium screen and choose Restore Purchases while signed in to the Apple Account used for the purchase. Contact us if your Premium access does not return.
How do I delete my data?
Use the erase-data option in Settings to remove your local profile and tracking history from this device. Exported copies saved elsewhere remain under your control. Erasing local data or deleting the app does not cancel an Apple subscription; manage it through your Apple Account.
