Common questions

How do I manage or cancel my Kairou subscription?

Subscriptions are handled by Apple. Open Settings → your name → Subscriptions on your iPhone, choose Kairou, and change or cancel there. You keep access until the end of the paid period, and your first 400 words stay free forever either way.

I bought Kairou when it was a one-time purchase. Do I need to subscribe?

No. If you bought Kairou as a paid app, you have lifetime access to everything. If something looks locked, email us and we’ll straighten it out.

How do I restore a purchase on a new device?

Make sure you’re signed in with the same Apple ID you bought with, and access restores automatically. If it doesn’t, email us with the rough purchase date.

How do refunds work?

Apple processes all App Store refunds at reportaproblem.apple.com. We can’t issue them directly, but email us if you’re stuck and we’ll help you through it.

Where is my progress stored?

On your device. There are no accounts. Progress, streaks, and card collections live locally, and everything works offline. Deleting the app deletes its data. Details on the privacy page.

Can more than one person use Kairou Kana?

Yes. Each player picks a name and keeps separate progress. Add or switch players from the menu on the Home screen or in Settings. Kairou Kana is free. No account, no ads.
