There's very little to say here as I only use Google Ads, so it's their own privacy policy which would be of more interest to yourselves.
The only logs I collect are generic access logs, this contains your IP Address, the request you made, the Date and Time of that request and your browsers header info, here is an example of such a log:
123.45.6.789 [27/Nov/2021:01:23:45 +0000] "GET /vids/bigbuckbunny/mp4/av1/1080/Big_Buck_Bunny_1080_10s_5MB.mp4 HTTP/2" 200 5252644" "https://example.com/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0b12) Gecko/20100101 Firefox/95.0b12"
This shows that a request came from 123.45.6.789 on the 27th November 2021 at 01:23:45. They requested the following data: /vids/bigbuckbunny/mp4/av1/1080/Big_Buck_Bunny_1080_10s_5MB.mp4, this request actually came from a different website, https://example.com, (this just means they have a link to my video) and the browser reported it was the Mozilla Firefox browser running on a Windows 10 64bit machine.
These logs are kept for a maximum of 10 days before being deleted.
I don't store anything else about users who use this site.
