VisionCircadian does not collect, store, transmit, or share any personal or sensitive user data.
All circadian light calculations are performed locally within the user's browser. No browsing history, webpage content, or identifying information is recorded or sent to any external servers.
The extension only accesses visible color information on the active webpage for the purpose of estimating circadian light exposure. This data is processed in real time and is not retained.
If you have questions, you may contact the developer.
