Get notified when sites update their terms of service▲190
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! [0]: https://news.ycombinator.com/item?id=37052508
