About your data

Is my data stored securely?

Data is what powers ground-breaking research that makes the world healthier. Eureka empowers everyone to securely contribute data to health causes they are passionate about. Maintaining the safety of the data you contribute is at the core of our mission and this motivates all of our technical decisions. Eureka uses a HIPAA compliant, cloud-based system to store all research data.

Who has access to my data?

If you choose to consent to participate in a research study, the study team will have access to your data for research. Your data will not be shared with any other party without your explicit consent.

What happens to my data if I choose to withdraw from a study?

If you choose to end your participation in a study (withdraw), we will stop collecting new data. Typically, data you have already contributed will still be maintained securely.

About your participation

Can I stop receiving reminder messages?

A study you join may decide to send text (SMS) messages to your phone to notify you of important study activities. If you prefer to not receive text (SMS) messages from the study, reply “STOP”.

Some studies on the Eureka app send “push messages” to remind participants to complete study activities. To turn off push notifications, go into your phone’s settings and toggle off messages from the Eureka app. If you wish to stop participating in a study, you need to withdraw from the study. You may contact a study coordinator with more questions.

How do I stop participating?

To stop participating in one or more studies, email the study coordinator with a request to withdraw from the study.

How can I change my password?

Go to settings and find the password section under basic info.

How do I access my informed consent(s)?

You’ll be able to see all of the consents from your studies in your settings page.

Who can I get in touch with to ask questions?

For questions about a specific study, contact the study coordinator. You can find your study coordinator’s contact information on the study website or in settings on the UCSF Eureka Research app.
