Privacy overview

The Relay service exposes a way for game developers to securely offer increased connectivity between players by using a join code style workflow without needing to invest in a third-party solution, maintain dedicated game servers (DGS), or worry about the network complexities of a peer-to-peer game. Instead of using DGS, the Relay service provides connectivity through a universal Relay server acting as a proxy.

This documentation is intended to assist products to display their privacy compliance to Developers. It is not intended to be used as legal guidance or as a replacement to reading Unity’s Privacy Policy. If you have questions about a term used, please see the Glossary below.

If you have further questions about the privacy implications of your product, please email with your question. For expediency, please list the product about which you are inquiring.

Personal data collected about app users/game-players

Default personal data collected (always collected in order for product to work)

  • IP address
  • Authentication Player ID

Developer defines

While this product allows for the collection of developer defined data, we require that you not collect personal data through this mechanism. Our systems will not understand that it is personal data and so such would not be treated as such in retention processes or data subject requests.

Relationship under privacy laws

Under GDPR, Unity is the Processor. You, the developer, are the Controller.

Under CCPA (as modified by CPRA), Unity is the Service Provider. You, the developer, are the Business.

As we are a Processor, we do not determine your legal basis for processing. Instead, it is your responsibility as the Controller to determine such a legal basis.

This product does not have a consent service. If the Developer determines they need to obtain consent, or provide an opt-out, they must implement it client-side in a way determined by the developer.

Data subject requests

Two of the most common data subject requests based in law are the request for access to personal data and the request for deletion of personal data.


This service has no native functionality to support data access requests. You, the developer, are responsible for actioning them. You can action them by reaching out to the Relay support team with the Player ID of the end user that requested access.


This service has no native functionality to support data deletion requests. You, the developer, are responsible for actioning them. You can action them by reaching out to the Relay support team with the Player ID of the end user that requested access.

Please note: This functionality only applies to this service. If you are using other services which collect app user personal data you will need to review that service's documentation for how it handles data deletion requests. To delete the Player ID created by the Unity Authentication SDK (if enabled), please use the Authentication API.

Data retention

Personal data is retained for 30 days.

Child privacy

If required to do so under applicable laws, you (the developer) must obtain Verified Parental Consent prior to submitting child-user data, as outlined in the Unity Terms of Service.

Privacy policy requirements

It is never appropriate to use Unity’s privacy policy for your application. You will need to ensure that the personal data practices are reflected in your Privacy Policy, as required in the Unity Terms of Service.

Data processing agreement (DPA)

The Unity DPA applies to the transfer of data for this product.
