BareMeta is built on excellent open-source software. The components below are bundled into the
app that runs in your browser, and we gratefully acknowledge their authors and licences.
Bundled runtime components
Map data & tiles
The optional GPS map preview displays map data from
© OpenStreetMap contributors. OpenStreetMap data is made available under the
Open Database License (ODbL), and the map tiles are used in accordance with the
OpenStreetMap Foundation's
tile usage policy.
See the
OpenStreetMap copyright page
for details. Map tiles are fetched live only when you open the preview and are never cached by BareMeta.

Wrangler — that are used only to build and test the project and are not shipped
in the app delivered to your browser. Each is distributed under its own license (predominantly
MIT, with Apache-2.0 for TypeScript). Their notices are available in their respective
repositories.
