How do you use my health data?

We use your heart rate and health data to improve Cardiogram’s features and accuracy. For example, the automatic tagging feature uses machine learning to detect heart rate spikes, which are then displayed on your Timeline. To power this feature, your heart rate data is securely uploaded to Cardiogram’s web servers for analysis.

What we do with your data

• We use your data to improve the Cardiogram app and its health-related features

• We do not sell your data or use it for advertising or marketing

• We never share your individual data unless you give us explicit permission
