A question, a problem or an idea? Write to me. Period. is made by one person, and every message is read.

official.jns.on@gmail.com

You can also send feedback from inside the app; it opens a Mail draft that you send yourself. Please don't include health details you'd rather keep private: they aren't needed to help you.

Where are my entries?

Only on your iPhone, in an encrypted database. There is no account and no server, so I can't see, recover or restore your entries for you.

How do I move to a new iPhone?

Under Settings → Backup, save a backup protected with a password, for example to iCloud Drive. On the new iPhone, install Period. and restore that file. Keep the password safe: the backup can't be opened without it.

Can I bring my history from another app?

Yes. Export your data from the other app (for example Clue, Flo or Apple Health), then import the file in Period. through the Files picker. The file is read on your phone and not sent anywhere.

My reminders don't appear

Check that notifications for Period. are allowed in the iPhone's Settings → Notifications, and that the reminder is turned on in Period. under Settings → Reminders.

How do I delete everything?

Settings → Delete all data removes everything from your phone for good, as does deleting the app. Backups you saved elsewhere stay there until you delete them.

Can I use Period. for contraception?

No. Period. is a diary, not a medical device. Its estimates are windows of days, not a method of contraception or a diagnosis. For medical questions, please talk to a doctor.
