OnCoord relies on a variety of open data sources to power our service. Each of these sources is governed by its own license, which places certain requirements on both OnCoord and you as a user of our services.
This attribution must remain visible to end users whenever map or geocoding results are displayed.

The OpenStreetMap project requires attribution whenever data from OSM may be displayed to an end user. OpenStreetMap data © OpenStreetMap contributors is used under the Open Database License (ODbL).
In general, geocoding results that include OpenStreetMap data do not trigger the share-alike provision of the Open Database License (ODbL), because they are considered "insubstantial database extracts".
This means that even if you combine those results with your own data and choose to release it publicly, you do not have to license that data under the ODbL.
However, if you use an OSM-based geocoder to systematically and methodically extract data from OpenStreetMap (for example, by reverse geocoding every square meter of an entire city or country), then you must use the ODbL for any publicly released data.
See our data sources page for the complete list of datasets used by OnCoord.
