  3. Device and technical information (where applicable), such as device model, OS version, app version, network type, and diagnostic or crash data to maintain security and improve stability.

We do not use your personal information for unrelated marketing unless we obtain your separate consent.

You may exercise these rights through in-app settings where available, or by contacting us using the details at the end of this policy. We will respond within a reasonable time as required by law.

9. Children

We do not knowingly collect personal information from children under the age required for valid consent in your jurisdiction without parental consent. If you believe we have collected such information, contact us and we will take steps to delete it.
