How bad is the tracking on the wikipedia mobile app?

> We assessed Wikipedia browsing data from 482,760 people collated across 50 countries or territories and 14 languages. Naturalistic Wikipedia browsing data were collected for the months of March 2022 and October 2022 from the webrequest logs (142). In general, these data are continuously and automatically collected for analytic purposes on Wikimedia’s infrastructure and deleted after 90 days. We only considered requests from the mobile app to articles in the main namespace. We discard requests marked as automated traffic or coming from bots (143). We identify unique readers via the wmfuuid (144) associated with the app installation (readers of the app have the option to turn off sending this ID with their requests).

Sure server log is fair game, but I don't see any option to opt out of wmfuuid on my app downloaded from f-droid.
