Cookies
The short, honest version.
No tracking cookies. No advertising cookies, no analytics cookies, no third-party cookies. Nobody is watching you here.
Two technical cookies, that is all. A session cookie, which is how your phone stays connected to your room, the site cannot work without it. And a security cookie that protects the forms you submit. Both are ours alone, and neither identifies who you are.
That is the whole policy. If you block cookies in your browser, the rooms will stop working, the rest of the site will mostly carry on.
