How do you use my health data?

Cardiogram uses heart rate and health data for internal research to enhance the features of the app. One such example is the tagging feature, which identifies spikes in heart rate using machine learning techniques. To perform this analysis, the heart rate data is uploaded to Cardiogram's web servers. This enables Cardiogram to analyze the data and identify spikes in heart rate for the user to tag and also helps to improve the algorithm.

  • Our internal projects are health-related. We won't share an individual's data with anyone unless we get his or her explicit permission. To be clear, data will not be used or sold for advertising or marketing.
  • If you were a part of the mRhythm study, your heart rate data may be shared with the UCSF (University of California San Francisco) team for the purposes of validating how well the Apple Watch can detect atrial fibrillation. As part of the mRhythm study, you will need to create a Health eHeart account and be asked a few additional questions about your medical history--this data will be managed by UCSF and stored separately from the Cardiogram heart rate data.  

Please visit our privacy policy if you have further questions. It's very important to us that Cardiogram users understand and are comfortable with how their data is used, so if you have further questions, please reach out to our support team. We can be reached at [email protected]
