Google Classroom Dark Mode is a free add-on for Chrome that transforms Google Classroom into a cooler, more stylish dark version. The extension is fully functional but may have areas that were untouched and are being worked on currently. The code used for the dark mode is original, so there might be bugs and areas that are not the correct color, style, etc.

The extension has been updated to Manifest Version 3, and most bugs have been fixed. The teacher support has also been updated (WIP), and an issue where classrooms with a dark color scheme had a bad color contrast has been fixed. The extension uses the storage function to save your selected color mode on the extension, so the next time you come to classroom, your settings are saved and reapplied.

It's important to note that the extension does not collect any of your data. The developer encourages users to report any bugs or areas that do not look visually correct.
