Since this uses Google Fonts, then Google may collect data about the users. You trade your data to Google in return for these fonts.
This project is a clean Rust implementation of TypeCatcher, which took about two days. It is a GTK3 application for browsing through and installing fonts from Google’s font archive from the comfort of your Linux desktop. Compared to TypeCatcher, which is written in Python, Font Finder also enables the ability to filter fonts by their categories, has zero Python runtime dependencies, and has much better performance & resource consumption.
