Analytics and Efficacy

This is a compilation of documentation available on how different countries approach analytics and telemetry of their apps and how they use that data to inform the potential efficacy of the exposure notification technology.

ENPA

If you are running ENX, please contact your Google and Apple developer relations teams about enrolling in ENPA. For those setting up ENPA, we strongly recommend including the opt-in for analytics to your current app sign-up process, even if you are not yet enrolled in ENPA. Having pre-authorization for anonymous, aggregated analytics will help you collect better information faster so you can adjust your system moving forward.

More information coming soon.
