Last Updated February 4, 2021

Sovrn strives to provide buyers and sellers with a safe, transparent, and fair marketplace. The following outlines the basic standards Sovrn employs to vet publishers wishing to participate on Sovrn’s ad exchange. This does not constitute a full list and is meant only as a guide for publishers wanting to work with Sovrn.

Sovrn reserves the right to update this list at any time without notice and to refuse or revoke participation of any publisher based on its own judgement.

If you transfer “personal data” (as defined by the General Data Protection Regulation (GDPR)) of individuals in the European Economic Area (EEA) to Sovrn’s ad exchange, and you want to make your inventory available to Google’s DBM platform, you agree: (1) to comply with Google’s EU User Consent Policy available here, and any updates to it, and (2) to obtain consent from your readers in the EEA to the processing of their personal data by the vendors listed here, and any vendors that may be added to this list in the future.
