How Much Data Does Google Collect from Your Android Phone

The hidden tracking inside a stock Android phone — and what you can do about it.

When Willem set up a budget Android phone, he discovered just how much data Google collects by default — location history, app usage, voice recordings, and more. Here's what he found and how to reduce it.

A stock Android phone with a Google account sends a remarkable amount of data back to Google. During setup, Willem documented each permission request and data collection toggle.

The defaults are aggressive: location history is on, web & app activity is on, voice & audio activity records what you say to Google Assistant, YouTube history tracks what you watch. All of this is tied to your Google account and used for advertising.

You can disable most of it: go to Settings → Google → Manage your Google Account → Data & Privacy. But the opt-out is buried deep, and some tracking can't be fully disabled without going Google-free entirely.

Willem eventually went further — running Android without Google services at all. That's documented in the Android without Google narrative.
