  • Text colors
  • Background colors
  • Display effects
  • Scroll speed

  • Precise location

9. Data Security

We take reasonable measures to help protect your information.

Since messages are stored locally on your device, you are responsible for protecting access to your device.

No method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.

10. Data Retention

Your locally stored information remains on your device until:

  • You delete it within the app

Emails sent to us are retained only as necessary to respond to your inquiries.
