the app is designed to fetch bookmark info when sharing link to the android app via share button 'add bookmark'.
from what i observed, this is done to set a bookmark description based on that website's text.
however, this involves downloading the actual webpage from the link connecting to all it's endpoints in the process, including to telemetry/ads/3rd parties/google/ you name it (as seen in netguard)
THIS IS A HUGE PRIVACY ISSUE and should be fixed asap
i suggest adding a toggle in t he settings to disable URL fetching which should be disabled by default.
