# Data ownership The ownership of the transferred data between Mage and Angel belongs to the Mage. In every research, the participant gives the right to Mage to access their data that has been provided voluntarily. Also, participants are free to give access to their bio-signal data to over one researcher (Mage) and participate in more than one research project (Contradiction with the Mage’s data ownership). Because of the decentralized nature of the Zarela, no personal information such as telephone number or email or any private information will be revealed to any Mage or never stored elsewhere. Zarela does not build any database of its users’ choices and decisions. To facilitate and enhance the user experience when using the application, Zarela has a built-in feature that allows the users to store and retrieve information of their choice in their browser. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
