After a regular review, we have determined that your app lowers a user’s device security by modifying or disabling SELinux on the device. To ensure a safe user experience for Play users, we have determined that apps with this functionality are noncompliant.
Please remove this functionality from your app within 14 days to achieve policy compliance. Once approved, your application will again be available with all installs, ratings and reviews intact.

You can avoid further administrative action by immediately ensuring that no other apps in your catalog are in violation of (but not limited to) the above policy.

All violations are tracked. Additional suspensions of any nature may result in the termination of your developer account, and investigation and possible termination of related Google accounts. If your account is terminated, payments will cease and Google may recover the proceeds of any past sales and/or the cost of any associated fees (such as chargebacks and transaction fees) from you.
