How do I cancel Tideline Plus?

On your iPhone: Settings → your name → Subscriptions → Tideline → Cancel. You keep Plus until the period you paid for ends. Deleting the app does not cancel a subscription.

I was charged after the free month

The free month turns into the yearly plan unless it is cancelled at least 24 hours before it ends. Apple handles all refunds: go to reportaproblem.apple.com, sign in, and choose "Request a refund".

I paid, but Plus is locked

Open the plan screen and tap Restore at the top right. It looks for purchases made with the Apple ID that is signed in on the phone.

How do I move my record to a new iPhone?

Your record lives only on your phone, so it moves with your iPhone backup: set up the new phone from your iCloud or computer backup and Tideline comes with it. You can also save your record as a file first (You → Export my record).

Can I bring my period dates from another app?

Yes, if that app saves them to Apple Health (Flo, Clue and Apple's own Cycle Tracking can). In Tideline: You → Import from Apple Health. Tideline only reads; it never writes to Apple Health.

My partner's screen says the link ran out

A link works for 45 days. Send a new one from You → Share with a partner. There is no server in between, which is also why a link cannot be taken back once sent.

How do I delete everything?

You → Delete everything. It erases every entry, your cycle and your settings from the phone at once and cannot be undone.

Is Tideline a medical app?

No. It keeps a record and summarises it. It does not diagnose or treat anything, and it is not birth control. If you are in crisis or thinking about harming yourself, call your local emergency number or a crisis line now.
