Summary
Dual N-Back Challenge stores your app data locally on your device. We do not run analytics, we do not show ads, and we do not sell your information.
This Privacy Policy explains what information (if any) is collected when you use the app and how it is handled.
Data we collect
We do not collect personal data through the app.
- No account creation, no login, and no user profiles.
- No advertising identifiers.
- No third-party analytics or tracking SDKs.
- No payment or billing information (the app is currently free and not charging users).
If you contact us by email, we receive your email address and message content to respond to your request.
Local-only storage
The app’s data is stored on your device. We do not upload your app data to our own servers.
Note: Your device or operating system may provide backup features. Those are controlled by you and your platform provider.
App permissions
The app may request device permissions only to enable features you choose to use. Any data accessed via permissions stays on your device unless you explicitly export or share it.
You can manage permissions any time in Settings on your device.
Data retention and deletion
Because app data is stored locally on your device, you control retention.
- You can delete data within the app if the app provides a delete/reset option.
- You can remove the app from your device to delete locally stored data (subject to device backup behavior).
Security
We design the app so your data remains on-device. No storage method is perfectly secure, but local-only storage reduces exposure.
Children’s privacy
The app is not intended for children under 10. We do not knowingly collect personal information from children.
Changes to this policy
We may update this Privacy Policy as the app evolves. When we make changes, we update the Last updated date at the top of this page.
