Permissions

In order to perform various tasks and provide a cohesive email client, K-9 uses various permissions. See our Privacy Policy for information on how we handle personal information obtained via these permissions.

For Android 6 and above, only the Contacts permission will be requested by a system dialog when you use the app. The rest are granted automatically when you install K-9.
