Additional request on my website

Hi!

I’m using your plugin, filters and everything work perfectly, but your plugin is adding additional request on the page using:
https://api.crashlytics.ru/tracking/script.js?

I don’t want to use crashlytics.ru

Can I somehow exclude this request from my website? You can see this request here in the “Waterfall” section: https://gtmetrix.com/reports/test.languagemix.com/d2zPMShq/

The page I need help with: [log in to see the link]
