When you upload a dataset to Mozilla Data Collective, you have the option to make your dataset exclusive to MDC. The default [t](https://datacollective.mozillafoundation.org/terms/providers?ref=community.mozilladatacollective.com#2-data-supplier-rights-and-obligations)[erms of use for data providers](https://datacollective.mozillafoundation.org/terms/providers?ref=community.mozilladatacollective.com#2-data-supplier-rights-and-obligations) on the platform is that datasets are exclusive to MDC. Choosing to host your dataset exclusively with MDC means that you do not plan on hosting the same version of the dataset on other data-sharing platforms, or making it available through other access endpoints. 

Exclusively hosting your *dataset* on Mozilla Data Collective does not mean that the *data* in the dataset is not available in some form online, but instead refers to the collection of data as a whole. Many exclusively hosted datasets might have components of their data that have been sourced from various places online, but have had additional processing and structured added to them when they were included in the dataset.

Mozilla Data Collective provides protections, management controls and visibility for datasets hosted on the Platform. These safeguards and insights apply in full when your dataset is hosted exclusively on the Platform. If your dataset will also be hosted or made accessible in other places, certain of these protections and visibility features may not apply. 

During the upload process, you should consider whether you intend to make your dataset available through MDC, or if you will also be hosting it on another site. If you are planning to make your dataset available on different platforms in addition to Mozilla Data Collective, you should check this box when you submit your dataset and review [Appendix 1 for data providers in the terms of use](https://datacollective.mozillafoundation.org/terms/providers?ref=community.mozilladatacollective.com#appendix-1). If you are planning to make your dataset available through Mozilla Dataset exclusively, leave this box unchecked.
