โ˜… PERMISSIONS โ˜…

Checkbot will ask for the "Read and change all your data..." permission for the sole purpose of crawling and testing the websites you ask Checkbot to check. This is currently the most restrictive permission we can ask for that allows this and Google has also reviewed this extension to check it follows best practices on requesting permissions. Your regular browsing will be unaffected: Checkbot does not observe or modify anything outside of the Checkbot tab. If you still have concerns, you can opt to create a new Chrome user profile to install Checkbot inside of to isolate it from your regular browsing.
