Native App Privacy

Full Title and Meme

An application that is installed on a user's computing device can be given access to some parts of user Privacy.

The first of the Laws of Security tell us that when an attacker gets to run their code on your computer, it is not longer just your computer any longer.
There are two parts to Privacy (the right to be let alone) that are should be subject to User Consent on a portable computer device, like a smart phone:
- Attention, or just how annoying do we want a device in our immediate possession to be?
- User Private Information that we would like to be able to share only with permission. This is the Data Sharing that is regulated by the GDPR and
Android App list of Data Categories that require User Consent. https://support.google.com/googleplay/answer/6270602?hl=en

Each company puts a majority of their settings under the settings tab, but then there are other setting that occur in other locations.
Each company also supplies an "Identity Server" that provide, Apple ID, Google ID and Microsoft ID that have a rich history of providing other services, especially email.
Each of those ID offerings are slightly different and are responsible for the Data Sharing part of privacy.
