JavaScript collects the text of your content blocks only to pass it through an MD5 function to generate a key. The hash is stored in chrome storage if you click "Reviewed", and never goes to a server. This value will be referred to as your "code hash" in the rest of this policy.
Any changes to settings in the extensions popup (as seen when you click on the extension icon) are stored in chrome storage. Nothing leaves your web browser; nothing goes to a server.
We use the code hash to determine if a subsequent commit has a change to that file that you have not previously seen.
The process looks like this:
Your information doesn't leave the browser. We don't collect it, thus it can not be shared.
