Bypass Paywall Clean -call home

Having looked at various browsers and what calls they make, I noticed on Firefox and other android browsers that when Bypass Paywall Clean is installed from main source: https://gitflic.ru/project/magnolia1234/bypass-paywalls-chrome-clean

It makes calls to gitflic.ru quite often wether using a bypass website or not.

Anyone know on what the calls are about and if they are legitimate and or what telemetry is being shared?
