Your progress stays on your iPhone.

What we collect

Nothing that identifies you. thinkin has no accounts, no ads and no analytics or tracking tools. Your game results, levels and settings are stored on your device and never sent to us.

Purchases

Subscriptions are handled entirely by Apple through your Apple Account. We never see your payment details. Apple tells the app whether your subscription is active.

Backups and deleting your data

Your progress is included in your iPhone’s iCloud backup, so it moves with you to a new phone. Settings › Reset all progress clears it in the app, and deleting the app removes everything it stored on your device. Your subscription always restores with your Apple Account.

Reminders

Daily reminders are scheduled on your iPhone. They are never sent from a server, and you can turn them off any time.

Permissions

Notifications are optional and used only for your daily reminder. If you choose Save Image when sharing a card, thinkin asks to add that one image to Photos; it can’t see your library.

Crash reports

If you’ve chosen to share analytics with app developers in your iPhone’s Settings, Apple sends us anonymous crash reports and usage statistics. We can’t link them to you.

Children

thinkin is rated 4+ and suitable for all ages. It collects no personal information from anyone, including children: there are no accounts, ads, analytics or tracking.

If you email us

We receive your email address and what you write, and use them only to reply. We never share or sell them, and we delete them within 12 months, or sooner if you ask.

This website
