WE CARE ABOUT PRIVACY
Instead of simply pointing you to our privacy policy. We would like to address this topic in the most understandable language here.
This extension is serverless - no requests are being made. The only data it collects and stores locally (on your computer) is what type of font have you chosen and the preferred source code view.
