TL;DR: We are GDPR compliant, aligning with one of the world's most protective data privacy laws. This ensures your data is handled with the highest standard of care, transparency, and security.

Information We Collect

Cronus collects information to provide better services to our users. We collect information in the following ways:

  • Information You Provide: This includes your name and email address when you register for an account.
  • Activity and Usage Data: We collect data from your device to power our automatic time-tracking features. This includes metadata about the applications you use and the websites you visit, such as window titles and URLs.

    For more accurate categorization, you can optionally grant permission for screen recordings. This feature captures screenshots that are processed locally on your device to extract text. These screenshots and the extracted text are never sent to our servers or stored. If you choose not to enable this optional feature, we only collect the basic metadata mentioned above.
