trade free, no ads, no tracker, database regularly updated, vast expanding database

Kiwix can be considered as 100% trade-free, because of the following: “Kiwix is a registered not-for-profit entity. We do not collect user data, nor do we put ads anywhere. Kiwix is entirely free and open-source, meaning that you can share and distribute it without having to ask for our permission (do drop us a note as a courtesy so we know where our users are; pictures are awesome too).” (https://www.kiwix.org/en/documentation/) 5/5 blocks for that!
