+## **Q:** What data is collected by Invidious?
+
+**A:** Invidious by itself does not collect any data about its users, but
+keep in mind that instance owners can log your IP address (like any other
+server on the internet).
+
+By default, the server logs which URLs were accessed, the associated error
+code (e.g 404 if the URL was not found) and the time it took for the server
+to respond.
+
+Here is what the server logs looks like:
+
+```
+2021-08-30 18:15:44 UTC [info] 200 GET /watch?v=GIAKHj9uJtM 781.21ms
+2021-08-30 18:15:49 UTC [info] 200 GET /api/v1/search?q=Fly%20away 500.0ms
+2021-08-30 18:15:49 UTC [info] 200 GET /vi/lJcqAzWFWLs/mqdefault.jpg 15.82ms
+2021-08-30 18:15:49 UTC [info] 200 GET /vi/JoP_Tte7z7o/mqdefault.jpg 70.64ms
+```
+
+When you create an account, your watch history and the list of channels you
+subscribed will be stored in the server's database. You can export, migrate
+or delete these data at any time from your user account page.
+

+
+## **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 know as a "proxy") between you and
+Google's servers, which will hide your IP address and the other information
+sent by your browser.
