from invidious faq:
Q: What data is shared with YouTube?
A: By default, the video stream is fetched directly from Google's servers (googlevideo.com) in order to reduce the bandwidth required by invidious, meaning that Google will be able to see your IP address and some other data commonly sent by web browsers, like your user-agent string.
If you don't want that to happen, you can go to the preferences page and check the Proxy videos option. When this option is enabled, the Invidious instance will be used as a relay (also known as a "proxy") between you and Google's servers, which will hide your IP address and the other information sent by your browser.
