TOSBack is a collaboration between the EFF, the Internet Society, and ToS;DR. Every day, we check the Terms and Policies of many online services to see if any of them have changed. The project is currently in beta as we are working on some improvements to ensure greater reliability and coverage. For now, please double check any results with the website operator before relying on them for important legal or journalistic purposes. More crawl data (including the full html pages) is available at tosback.eff.org (same warning applies).
