Co Maps delivers offline navigation for hiking, biking, and driving using only GPS — no mobile data required. The app searches waypoints on remote trails and plans routes abroad without a cellular connection. Built as a fork of Organic Maps and Maps.me, it runs on OpenStreetMap data and hosts its code on Codeberg under an open-source license.

Privacy sits at the architecture level: the app collects zero user data, performs no tracking, and carries an Exodus audit confirming no hidden telemetry. Battery consumption stays low compared to cloud-dependent alternatives, a practical advantage for multi-day backcountry trips where charging opportunities are scarce.

Community contributions drive development. Users add points of interest to OpenStreetMap, report issues, and submit patches directly to the repository. This model keeps map detail current in regions where commercial providers lag, especially on hiking paths and cycling infrastructure.

The project proves that privacy-respecting offline navigation can match cloud-backed features without compromise. For travelers and outdoor users, it removes the data-roaming tax and the surveillance trade-off in a single package.
