Terms

The short version: play as much as you like, in your browser, for free. Don't copy the game, and don't scrape the map data off our servers.

The software is ours

CHARTED's code, art and design are © 2026 CHARTED, all rights reserved. They are proprietary: you may not copy, modify, redistribute or host them anywhere else without our written permission. That includes putting the game on another site or in an app.

The third-party software it is built with (three.js, MapLibre, PMTiles and others) keeps its own licence; see data & credits.

The map data is open data

The world is drawn from open data, and that data stays under its own licences, which data & credits lists: OpenStreetMap-derived data (via Overture Maps and Protomaps) under the Open Database License (ODbL), Overture's own data under CDLA-Permissive-2.0, elevation from Mapterhorn under its sources' open licences (CC-BY and others), and the ocean floor (GEBCO) and Natural Earth in the public domain.

As the ODbL asks, the database we derive from OpenStreetMap data is available on request: contact us through playcharted.com.

Use it through the app

Our data host (data.playcharted.com) is there for the game, not as a download service. Don't download from it automatically or in bulk (scrapers, crawlers, mirroring, proxies or other sites hotlinking it); use the game in your browser. The underlying open data is freely available from its original sources.

No framing

Don't show CHARTED inside a frame on another site. Link to it instead.

No warranty

CHARTED is provided as it is, without warranty of any kind. Maps can be wrong, out of date or incomplete: never use it for navigation, at sea or anywhere else. We aren't liable for any loss that comes from using it, to the extent the law allows.
