If you want to know how to stop app tracking on Android, you have to look beyond the standard privacy settings. Let’s be honest: Android is an advertising platform first, and an operating system second.
Google’s entire business model relies on knowing where you are, what you buy, and who you sleep next to. When you read generic privacy guides that tell you to “turn off cookies” or “ask apps not to track,” you are bringing a knife to a gunfight.
Most settings to turn off app tracking are placebos. They give you the feeling of control while the OS continues to hemorrhage your data to data brokers in the background.
To actually stop the bleeding, you need to go deeper than the “Privacy” menu. You need to kill the unique identifiers that link your identity across apps and, when necessary, cut the power to your sensors entirely.
Here is how to lock down any Android device—from Samsung to Pixel—the right way.

Layer 1: Delete Android Advertising ID (The Hidden Tracker)
Every Android phone comes out of the box with a unique digital license plate called the GAID (Google Advertising ID). Deleting this ID is the most effective way to block cross-app tracking on Android devices.
This is the mechanism that allows companies to track you across different apps. When you look at sneakers in a shopping app and then see sneaker ads in a weather app five minutes later, it’s not magic—it’s your GAID. Data brokers match these two interactions to build a single, cohesive profile of your life.
Most users “Reset” this ID thinking it helps. It doesn’t. Resetting just changes your license plate number; it doesn’t take the car off the road. You must delete it.
The Fix (Universal Path):
- Open Settings.
- Navigate to Privacy > Ads (On some phones: Security & Privacy > Ads).
- Tap Delete advertising ID.
- Confirm Deletion.
Note: Once deleted, apps that ask for this ID will receive a string of zeros. You have effectively blinded them.
Layer 2: The “Permission Audit” (Be Ruthless)
Most people treat app permissions like Terms of Service agreements—they just click “Allow” to make the popup go away. This is a mistake.
If a Calculator app wants your Location, it is spyware. If a Flashlight app wants your Contacts, it is harvesting your social graph. You need to audit your permissions with zero tolerance.
1. The “Nearby Devices” Trap
This is the sneakiest permission in modern Android. Apps use “Nearby Devices” (Bluetooth scanning) to see who is standing next to you. Even if you turn off Location GPS, Facebook knows you are at a bar with your ex-girlfriend because your phones’ Bluetooth radios shook hands.
- Action: Go to Settings > Privacy > Permission Manager > Nearby Devices. Revoke this for everything except headphones and smartwatches.
2. Location: “Precise” vs. “Approximate”
Uber needs your precise location. Instagram does not.
- Action: When an app asks for location, never select “Always Allow.” If you must grant it, select “Only while using the app” and toggle OFF the “Use Precise Location” switch. Force them to track you to a city block, not your bedroom.
Layer 3: The “Nuclear Option” (Sensors Off)
If you are truly serious about privacy—for example, you are entering a sensitive meeting or believe your device is compromised—software toggles aren’t enough. You need to cut the power to the sensors.
Android includes a hidden developer switch called “Sensors Off.” This is not a “soft” mute. It is a system-level override that physically ignores data from the Camera, Microphone, Accelerometer, and Gyroscope.
Step 1: Unlock Developer Mode
- Go to Settings > About Phone.
- Find Build Number.
- Tap it 7 times rapidly until you see the message: “You are now a developer.”
- Enter your PIN to confirm.
Step 2: Activate the Kill Switch
- Go back to Settings > System > Developer options.
- Scroll down to Quick settings developer tiles.
- Toggle ON the switch for Sensors Off.
Step 3: How to Use It
You now have a new button in your Quick Settings panel (next to your WiFi and Bluetooth toggles). It looks like a heart rate monitor line with a slash through it.
- Tap it ON: Your cameras, mics, and GPS sensors go dead. If you open the Camera app, it will crash or show black.
- Tap it OFF: Your phone returns to normal.
Layer 4: The “Quarantine Zone” (Android 15 Private Space)
If you own a device running Android 15 (released late 2024), you have the most powerful anti-tracking tool Google has ever released—though they market it as a way to hide “sensitive” apps.
Private Space is not just a hidden folder; it is a sandboxed operating system within your phone. Android 15 gives us a new, powerful method for how to stop app tracking on Android by isolating apps in a sandbox.
When you move an app like TikTok or Facebook into Private Space and lock it, that app suffers “process death.” It cannot run in the background. It cannot ping your location. It cannot upload your contacts. It is frozen in carbonite until you explicitly unlock the space again.
The Strategy: Quarantine the Spies
Don’t use Private Space for banking apps. Use it for the invasive apps you “need” but don’t trust.
- Setup: Go to Settings > Security & Privacy > Private Space.
- Authentication: Set a different PIN/Fingerprint than your main lock screen.
- Isolation: Create a brand new, anonymous Google Account for this space. Do not sign in with your main Gmail.
- Action: Uninstall Facebook/TikTok from your main profile and reinstall them inside Private Space.
Now, these apps can only track you when you are actively looking at them. The moment you lock the space, they cease to exist.
Layer 5: Cut the Cord to the Mothership (Usage & Diagnostics)
While you are busy blocking third-party apps, don’t forget the spy in your pocket: Google itself.
By default, your phone sends a constant stream of “telemetry” data back to Google servers. They claim this is for “battery life” and “system stability,” but it also includes granular details on how often you open apps and your network connections.
The Fix:
- Open Settings.
- Go to Google > Usage & diagnostics (or Security & Privacy > More privacy settings > Usage & diagnostics).
- Toggle it OFF.
Note: This does not break your phone. It simply stops you from being an unpaid beta tester for Google’s algorithms.
The Verdict: How to Stop App Tracking on Android Permanently
If you take one thing from this guide, let it be this: “Privacy” on Android is not a switch you flip once. It is a constant battle against an operating system designed to monetize your behavior.
- Deleting your Advertising ID stops the cross-app profiling.
- The “Sensors Off” tile is your physical shield against surveillance.
- Private Space is your quarantine zone for necessary evils.
Most users will leave their phones on default settings and pay for “free” apps with their personal data. You are now part of the 1% who knows how to fight back.
