Your Android phone knows more about you than almost any other device you own. Where you go, who you talk to, what you search for, and what you spend your money on. Some of that data exchange is the cost of using services you genuinely want. A lot of it is happening without your informed consent, because the default settings on Android weren't configured with your privacy as the priority.This section covers Android privacy and security in practical terms. Not in the abstract, and not with alarm tactics designed to sell you something you don't need. You'll find step-by-step guides for auditing your app permissions, locking down your Google account, setting up two-factor authentication properly, configuring a VPN, understanding what each privacy setting actually does, and recovering from a compromised account.The approach here is honest: some of these measures will meaningfully improve your security, and some are overkill for most people. The guides tell you which is which.
