uBlock Origin does not collect any data of any kind.

• uBlock Origin has no home server.
• uBlock Origin doesn't embed any kind of analytic hooks in its code.

As of version 1.11.0, the quoted passage below is not longer true -- uBlock Origin will no longer use the resource checksums/ublock0.txt (the quoted text will be removed once version 1.11.0 is widespread):

uBlock Origin will download the resource at https://raw.githubusercontent.com/uBlockOrigin/uAssets/master/checksums/ublock0.txt?_=[unix time stamp in ms]

• when you visit the 3rd-party filters pane in the dashboard;
• once in a while if you have Auto-update filter lists checked;

... to find out whether some assets used by uBlock Origin need to be updated.

The purpose of the unix time stamp in ms portion of the URL is to be sure the browser cache is bypassed.

The only time uBlock Origin connects to a remote server is to update the filter lists and other related assets. If you disable auto-update in the "3rd-party filters" pane in the dashboard, uBlock Origin will not connect to any remote server, unless you click "Update now" and only if there are assets deemed "out of date".

The servers behind githubusercontent.com are owned by GitHub, Inc., and thus are unrelated to uBlock Origin, so even if I was interested in analytics (which I am not), I have no access to whatever data is logged by githubusercontent.com.

That is all.
