If you deny access, the app cannot see any of your health information. If you change your mind, you can go back to the app later and give it access again. Denying access does not affect your MyChart account or your care.
If you revoke access, the app stops receiving new information from your health record. However, the app might still have information it already received. To request deletion of that information, contact the app directly. The app’s information practices might be available on the review page you saw when you first authorized the app.
To revoke access:
After access has been revoked, the app can no longer receive new information from your health record.
Give an app access to your health information or a family member's information.
Go to Linked Apps and Devices in MyChart to see which apps have access to your health information.
