• No account, no cloud. The app works offline; results are stored locally on your device.

Information We Do Not Collect

We do not collect contact information, identifiers, health data, sensitive data, location, usage data, diagnostics, purchase history, or any data used for tracking.

​

​

What Stays on Your Device

Your spiral drawings, tapping results, and settings are stored in the app’s local storage (e.g., on-device files/UserDefaults). We do not have access to this information. If you choose to export or share results using the iOS share sheet, the content you select goes only to the destination you choose.
Note: If you use iCloud Backup, iOS may include the app’s local data in your encrypted device backup. We do not access it.

​

Permissions

• Touch input / haptics: required for core features. No personal data is collected.

• Optional features (future): If a future version needs camera, microphone, or network access, we will request your consent in-app and update this policy before use.

Children’s Privacy

The app is intended for general audiences. If you are under the age required by your local law to provide consent, please use the app with a parent or guardian. We do not knowingly collect personal data from children.
