Privacy policy

1. About this policy

This privacy policy explains what information the app KanKey (“the app”) handles, why, and how. The app is run by [OPERATOR NAME] (“we”).

2. What stays on your phone

Profile names, goals, your answers, review schedules and settings are stored on your phone. Without an account, none of this is ever sent to us.

Study and review reminders and the number on the app icon are set up on your phone. We never send notifications from our server.

3. Account and sync

When you turn on sync (Plus), we store this on our server:

• Sign-in details: your email address, or your Apple or Google account ID (if you chose Hide My Email, the forwarding address Apple makes)

• The sessions of the devices you are signed in on

• Whether you have Plus

• Your profiles, answers, review schedules and settings

We use it to keep your devices in step and to back up your progress. It is stored on Cloudflare’s servers in the EU (Western Europe).

4. Sign-in emails

When you sign in with email, we send you a 6-digit code (through Cloudflare Email Service). When you change your email address, we also tell your old address. We never send marketing email.

5. Purchases

The App Store and Google Play handle purchases and payment; we never see your card or payment details. To check whether you have Plus we use RevenueCat, which receives your purchase records and your account ID (or a random ID if you have no account).

6. Mistake reports

When you report a mistake, we receive the question or page, what you wrote and the app version. Your email address is optional and used only to reply to you.

7. Crash reports

If the app crashes, it sends the device model, the OS and app versions and the error to Sentry so we can fix it. Crash reports contain no names or email addresses.

8. What we don’t do

No ads, no usage analytics, no tracking, and we never sell personal information.

9. Who else handles it

Only the services named here handle this information: Cloudflare, RevenueCat, Sentry, and Apple or Google when you sign in with them. We share it with no one else unless the law requires it. It may be handled outside your country. [TRANSFER SAFEGUARDS]

10. Keeping and deleting

Progress on your phone is deleted when you delete the app. Server data is kept until you delete your account, even after Plus ends.

You can delete your account in Settings › Delete account, or on the web at kankey.app/delete-account. Everything on our server is erased, and from backups within [BACKUP PERIOD]. The progress on your phone stays.

Deleting your account does not cancel your store subscription; cancel it in the store.

11. Your rights

You can ask to see, correct or delete your information, or ask us to stop using it. Write to contact@kankey.app. [SUPERVISORY AUTHORITY]

12. Children

Children can use the app without an account. Anyone under [AGE] needs a parent’s or guardian’s consent to create an account.

13. Changes to this policy

If we change this policy, we will tell you in the app and on the web.
