After reading about what happened with NightOwl yesterday [0], I thought about what it would take to be aware of things like that in the future. I created ToSNotify to automatically notify you when a website's terms change.
A harder problem I've been thinking through is how to know which terms to track, since it'd be a pain to add every site I have an account with. One idea I had is to automatically get terms for apps you have installed from the app store. Any other ideas/feedback are appreciated!

Have GitHub run a daily/weekly pull of the site in question. Attempt to add the artifact to the repo. If identical, no action taken. Otherwise, a commit is made with the new content, and you can now trivially diff the changes over time.
