- The page calls itself a non-commercial unofficial preservation project by pieter.com.
- It says "Play Real Quake II in your browser · up to 8 players · no install" and shows a top-players list.
- It offers an "Enable notifications" control. That is a browser permission; you can leave it off.
What we could not confirm

- We did not confirm whether it needs game data from a copy you own.
- The page does not say whether the rights holders approve it.
