Hello, We appreciate your feedback. 

We are using Bunny Fonts as it is a privacy focussed and GDPR compliant provider. The reason we use fonts in our extension is to allow librarians to select their libraries preferred font type to provide a customised experience to their patrons.

However, if there are any concern and feedback on Bunny Fonts, we would really appreciate if you could get in touch with us at support@leanlibrary.com so we can look into this further for you.

Best
Lean Library team
