Altered Device State Policy
Amazon does not permit apps that override or alter the native device OS or user experience (e.g., lockscreens, widgets, launchers, picture-in-picture windows, floating windows, or other on-screen or in-app elements that impact the native user interface). In limited cases we may permit overlay widgets if they are unobtrusive, integral to the app, and do not further alter the device.
Device and System Abuse
We prohibit apps that interfere with users' devices, our services, or other servers, networks, or third-party apps. For example, apps that interfere with or block another third party app from displaying ads are not permitted.
