Seems to be a nice UI around QtWebEngine which is based on WebKit or blink (chromium), with quite a solid effort through the years.
Are there any Google risks for being chromium-based? Honest question here.
Here's QT's note addressing your concern in QtWebEngine: https://wiki.qt.io/QtWebEngine#Relationship_to_Chromium
Auxiliary services that talk to Google platforms are stripped out- QtWebKit: https://wiki.qt.io/Qt_WebKit
