This website provides different tools that may help working with clear and DRM-protected media. These tools exist mainly for debugging purposes, since they may help to identify and solve potential problems with the media playback, but they're not limited only by this single purpose. The tools can be found through the main menu. Also, check out the release notes (see below), since they may contain additional useful info about the tools and everything related to them.
Some tools work with sensitive data. Such data is never logged. It's only used by tools to do their job. Some tools may also help to identify a specific client. Tools on this website never do anything like that, and never log information that can be later used for that.
