Dolunay support

Go to Settings > Data > Back up and follow “Create backup file”. Dolunay first asks you to set a passphrase (at least 10 characters). The file is encrypted with it and saved wherever you choose through the iOS share sheet: Files, AirDrop or email. The file is named like Dolunay-Yedek-YYYY-MM-DD.dolunay.

If you forget the passphrase the file cannot be opened; Dolunay cannot open it and neither can we. Keep the passphrase somewhere safe.

1. In Settings > Data > Restore, choose “Restore from a backup” and pick the .dolunay file.
2. Enter the passphrase. If it is wrong or the file is damaged, Dolunay says the backup could not be opened; the two cases cannot be told apart safely, so there is one message. You can try again and nothing changes.
3. The app summarises how many periods and day logs the backup contains.
4. If your phone already has records, they are replaced by the backup; there is no merge. Dolunay first keeps your current data as a local rollback copy for 7 days, and you can go back with Settings > Data > “Undo last restore”.

A damaged or incomplete file is never applied halfway: nothing changes until the file has been fully validated.

The way we can vouch for is the backup file: create a backup file on the old phone, send it to the new phone with AirDrop, then choose “Restore from a backup” there.

If you set up the new iPhone from the old one with Apple’s own transfer, your Dolunay data may come along, but we have not yet tested this with two devices, so we do not recommend relying on it. Before you erase the old phone, make a backup file and check that you can restore it on the new one.

Settings > Data > “Delete all data”. This deletes your day logs, cycles, settings, reminders, scheduled notifications, widget data, local rollback copies and the backup reminder state. If writing to Apple Health was ever turned on, you can also choose to delete the records Dolunay wrote; only the records Dolunay wrote are deleted.

Not deleted: backup files you saved elsewhere and exported files, and records written to Apple Health by other apps. Deleting the app also removes everything the app stored on the device.

If any step fails, Dolunay lists what remains and offers to try again; it never says it is done while data remains.

Yes. In Settings > Data > Export and import you can export everything as JSON or your day logs as CSV. These files are not encrypted; Dolunay says so before you share and offers the encrypted backup file instead. Sexual activity records are included in the JSON only if “Include sexual activity records” is on; it is off by default.

To import, you can use Apple Health or a CSV file of period dates (columns baslangic,bitis, dates as YYYY-MM-DD; bitis is optional). Before importing, Dolunay shows how many rows were read and skipped. Imported days never overwrite records you entered by hand. Dolunay does not claim to import any particular other app’s file.

In Settings > Apple Health, “Write to Apple Health from Dolunay” and “Import from Apple Health” are separate switches, and you can choose each record type to write. Dolunay writes only what you logged, never predictions. You can also change the permission in iOS Settings > Health. Dolunay works fully without Apple Health.

If Apple Health returns nothing, nothing is deleted in Dolunay. If both have data for the same day and they differ, your Dolunay record wins.

Cycle length varies from person to person and from month to month, and a single date looks more certain than it is. Dolunay shows a range and explains what it is based on in Settings > About > “How we calculate”. Dolunay is not a birth control method, does not diagnose and gives no accuracy percentage; predictions rely on calendar calculation and can change. Check with a doctor before medical decisions.

In Settings > Privacy and security you can turn on the app lock and choose the lock delay. It uses Face ID, Touch ID or your iPhone passcode. If your iPhone has no passcode at all, the lock cannot be opened and Dolunay explains why; the “Delete data and reset” link on the lock screen makes sure you are never stuck.

Dolunay is free; some screens show one card labelled “Sponsor” from a brand we deal with directly. The card is the same for everyone, is not based on your data, and Dolunay does not track you. Cards never appear in the logging flow, in notifications, in widgets or on the lock screen. More on the sponsorship page.
