I agree that my health data (heart rate, HRV, stress values) will be processed for use of the app. I have read the privacy policy.

I expressly request that the provision of the digital service (licence activation) begins before the end of the withdrawal period. I acknowledge that I thereby lose my right of withdrawal for the digital service. The right of withdrawal for the hardware (pulse sensor) remains unaffected.

After activation we will ask for your year of birth and gender. These are used for scientifically correct Relax Index calculation according to the Lifelines Cohort Study.
