Hey pacifika,
This includes data from your private repos to show a more complete picture for those that may have a lot of closed source contribs.
I totally get your hesitation to try it out, hence the link to the repo. You'd notice that your token isn't actually stored/sent to any database, or other internal system. It's kept as an HTTP-only secure cookie, encrypted using an RSA key-pair, on your browser only.
Happy to hear more feedback, or receive any contributions to support an public-only version of this.
