True Level 3 Privacy on your mobile device requires the use of a custom ROM. Stock Android is an excellent starting point, however, LinageOS and GrapheneOS have done a great job for a well thought out set of features, low hardware requirements, and great looks. Apple phones running with Zenfoil would be a good step to stop the data bleeding out to your network provider, but Apple service terms tie the hardware and system software together that make it a clear second choice in terms of privacy. Apple will capture GPS information at a system level whereas Stock Android, LinageOS, and GrapheneOS are fully functional without low level Google services and can be configured to have open source GPS and no system information leaking back to Google.
Computers, laptops, chromebooks, phones, and tablets (Apple, Microsoft, Google) running proprietary closed source operating systems all can only reach Level 2 privacy.
About Cloud Services
By using the ZenCloud, you replace the implicitly supplied cloud services of Google, Apple, Samsung and whomever else wedged their way onto your phone. This puts you in control of your data and stops your communications provider, commercial, state actors, or malicious private actors from having access to your data.
You may not even know that cloud services are part of your Bell or Rogers account. It’s automatically provided when you get a phone. Your service provider has a access to a complete copy of your phone. In the secure ZenCloud, only you can access your data from any of your devices.
