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 This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://whitepaper.zarela.io/challenges-and-solutions/data-ownership.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
