## Licensing
38+
Like all other Delphi Epidata datasets, our COVIDcast data is freely available to the public. However, our COVID-19 surveillance streams include data from many different sources, with data licensing handled separately for each source. For a summary of the licenses used and a list of the indicators each license applies to, we suggest users visit our [COVIDcast licensing](covidcast_licensing.md) page. Licensing information is also summarized on each indicator's details page.
