The Felix Debugger browser extension processes data exclusively locally on your device.

  • No personal data is collected, stored or transmitted.
  • No tracking or usage analysis takes place.
  • No data is sent to external servers or third parties.
  • The extension only accesses GA4 network requests from the currently open tab to display them in the DevTools debug panel. This processing is entirely local in your browser.
  • Inputs (e.g. filters, comparison data) remain in your local browser storage and are not synced.

No personal data is transmitted to us through use of the extension.
