Galaxi is a free Android app developed by Yleisradio Oy, designed for school-age children. It offers a range of game content and information on current issues in the Galaxy, bringing together all the Galaxy content in one place.

The app requires an internet connection to run, and its features include creating a community experience by providing information on current issues in the Galaxy, offering light gaming content, and bringing together Galaxy web content.

One of the best things about Galaxi is its focus on security and privacy. Users can use the app without making a nickname, and no personally identifiable information is collected from users. The creator of the nickname is only asked for a username and password, and all use is entirely anonymous. All links within the app lead to secure content that is almost invariably Galaxy's own content. If any content is produced by another party, it is declared safe by Galax.

Overall, Galaxi is a safe and fun app for kids that respects privacy and security while providing a range of engaging content.
