Support

Subscriptions are billed through your Apple Account, so you manage them in iOS Settings:

1. Open Settings on your iPhone or iPad.
2. Tap your name at the top, then Subscriptions.
3. Select KAI Tutor and choose to change plan or cancel.

Cancelling stops future renewals; you keep access until the end of the current period.

New users get a free trial period. If you don't cancel at least 24 hours before it ends, it converts automatically to a paid subscription (¥1,800 / month or ¥20,000 / year). You can cancel any time during the trial from your Apple subscription settings.

Purchases and refunds are handled by Apple. To request one, visit reportaproblem.apple.com, sign in with your Apple Account, select the purchase, and follow the prompts. If you have trouble, email us and we'll help where we can.

You can permanently delete your account inside the app:

1. Open the app and go to Settings → Account.
2. Tap Delete account and confirm.

This removes your personal learning data. You can also email kai@trigluon.ai from your account address to request deletion. Note: deleting your account does not cancel an active subscription — cancel that in Apple settings. See our Privacy Policy for details.

Make sure you have a stable internet connection and are signed in to the same account. Fully close and reopen the app to sync. If the issue persists, email us with your account email and a short description, and we'll investigate.

Yes. We use your data to personalize tutoring and never sell it. AI features send your submitted text (and speaking audio) to third-party AI providers that process it on our behalf under contract. Full details are in our Privacy Policy.

KAI Tutor runs on iPhone and iPad with a current version of iOS. An internet connection is required for AI-powered lessons and feedback.
