Is Bionic Reader safe?

Low risk

Bionic Reader imports Google Fonts CSS on webpages where it auto-applies its reading style.

With its default all-sites setting enabled, Bionic Reader injects CSS imports for Roboto font stylesheets before applying its page styling. The browser fetches those stylesheets from fonts.googleapis.com in the page context, sending referrer information according to the browser and site's referrer policy.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
