> We don't collect and store IPs.

First, "IPs" might be confusing; "IP addresses" would be more accurate.

More importantly, you have to collect IP addresses (or any other value in the packet headers[1][2]) - even if you don't store it - if you want to receive any packets from the rest of the internet. Storage of those values is separate issue entirely, and it's good to hear that you are intending to NOT store IP addresses (and updating the documenting)!

Also, I strongly recommend using Drdrdrq's suggestion to lower the precision of the collected window dimensions, which should be done on the client i.e. "Math.floor(window.innerWidth/50)*50". This kind of bit-reduction makes fingerprinting a lot harder.
