Your phone, laptop, and smart home devices can collect information about what you do, where you go, and which apps you use. Some tracking helps a service work, but some supports advertising or data collection you may not want. The good news is that a few free settings changes can reduce it without making your devices hard to use.
What Does Device Tracking Actually Mean?
Tracking is not one feature you can switch off. Apps, websites, and connected devices can collect different kinds of information. A maps app may need your location to give directions. A shopping app may record which products you view. A website may use cookies to remember your visit or measure which pages are popular.
Companies can also use information such as your account, advertising ID, device details, or internet connection to recognize your activity over time. The details they collect, and what they do with them, depend on the service and its settings. Turning off one form of tracking will not stop all the others.
Start with the apps and devices you already own rather than assuming a new gadget will solve the problem. If you are comparing phones, our guide to choosing a budget smartphone covers practical buying priorities. Whatever phone you choose, its privacy settings still deserve a look.
A useful question is: does this app need this information to do what I asked? That simple test helps you keep helpful features while cutting back on unnecessary access.
Ad IDs: A Setting Worth Checking
Phones may provide an advertising ID that apps can use for ad-related purposes. It is not your name, but it can help connect activity across apps that use it. Changing the ad ID setting can reduce one common way advertisers recognize your device; it does not stop every form of data collection.
On an iPhone, open Settings, then Privacy & Security, then Tracking. You can turn off “Allow Apps to Request to Track,” or review requests app by app. This controls the app-tracking permission covered by Apple’s system. It does not prevent an app from collecting information you give it directly, such as details entered into an account.
On Android, look in Settings for Privacy, Google, or Ads. Depending on your phone and software version, you may find options to delete or reset the advertising ID and manage ad privacy. Search Settings for “ads” if the menu is hard to find. Resetting an ID gives it a new value; deleting it is a different option where available.
You may still see ads after changing these settings. The aim is to reduce certain kinds of tracking or ad personalization, not to remove advertising entirely.
App Permissions: Give Access Only When Needed
Permissions let an app use parts of your device, such as the camera, microphone, contacts, photos, or location. Some requests are essential: a video calling app needs microphone access during a call. Others deserve a second look. A simple game, for example, may not need your contacts.
On iPhone or Android, open Settings and find Privacy or Permission Manager. Review access by category, or open an individual app’s settings. Where your phone offers the choice, use “only while using the app” for location, or allow camera and microphone access only when needed. You can change a permission later if a feature stops working.
Pay particular attention to apps you rarely open. Removing an unused app can be simpler than managing its permissions, though uninstalling it does not erase information the company already holds. If an old app is also taking up space, our guide to freeing up storage on an Android phone offers related cleanup steps.
Permissions are powerful, but they are not the whole privacy picture. An app can still collect information you type into it or generate while using its service.
Location: Choose How Precise and How Often
Location access is useful for maps, local weather, finding a lost device, and some safety features. It can also reveal sensitive routines, such as where you spend the night or which places you visit regularly. You do not have to switch off location for everything to make a meaningful change.
Check each app’s location permission. For an app that only needs your position while you use it, choose that option instead of allowing access all the time. If the app works with a general area, consider turning off precise location where your phone offers that choice. Keep precise access for tasks, such as turn-by-turn directions, that genuinely need it.
Wearables need the same attention. A fitness app may use location to map a run, while a step count may not need a route. Before connecting a wearable, it helps to understand the features you want from fitness trackers and smartwatches.
Also review any location history or timeline setting in your map account. Limiting an app’s current access and managing a saved history are separate jobs, so check both if you use those features.
Websites and Browsers Track Activity Too
Tracking is not limited to apps. Websites can use cookies and similar tools to remember visits, keep you signed in, measure traffic, or support advertising. Some tracking happens across different websites. Your browser may already block some of it, but its protection depends on your settings and the sites you visit.
Open your browser’s Privacy or Security settings and look for options that limit cross-site tracking or third-party cookies. You can also review saved site permissions for location, camera, microphone, and notifications. If a website no longer needs one, remove it. These changes are free and usually take only a few minutes.
Private browsing has a narrower purpose than its name suggests. It generally stops your browser from saving that session in its local history after you close the window. It does not make you invisible to websites, your internet provider, a school or workplace network, or services you sign in to.
Blocking more cookies may cause some sites to ask you to sign in again or remember fewer preferences. That is a trade-off you can adjust if a site you rely on stops working properly.
Smart Home Devices Need an Account Check
Smart speakers, cameras, TVs, and other connected devices may send information to a company account so their features work. What they collect varies widely. A camera needs video to show you a live view; a voice assistant needs to handle a request to answer it. That does not mean every optional history or sharing setting must stay on.
Open the device’s companion app and look for Privacy, Data, or History settings. Check whether you can manage saved voice recordings, activity history, personalized ads, or optional data sharing. If a setting is unclear, read its description before changing it so you know which feature might be affected.
Review who has access to the account, especially for cameras and doorbells. Remove people who no longer need access, use a strong unique password, and turn on two-factor authentication when offered. Keeping device software updated is important too: privacy settings do not replace security updates.
If you are planning a connected home, our smart home starter guide can help you think through which devices you actually need. Fewer connected devices can also mean fewer accounts and settings to manage.
A Simple Privacy Check You Can Do Today
You do not need to change every setting in one sitting. Start with the controls most likely to affect everyday tracking, then return to the rest when you have time. Menu names vary by device and software version, so use the search box in Settings if an option has moved.
- Review ad settings: Check your phone’s tracking or advertising ID options and choose what you are comfortable allowing.
- Check sensitive permissions: Look at location, microphone, camera, contacts, and photos. Remove access an app does not need.
- Limit location access: Prefer access while using an app when that is enough, and check whether precise location is necessary.
- Review your browser: Look at cross-site tracking or third-party cookie controls and clear old site permissions.
- Clean up accounts and apps: Uninstall apps you no longer use and check the privacy settings for services you keep.
After each change, try the feature you use most. If it no longer works as expected, you can restore the permission that feature needs without giving every app the same access. Repeat this check when you install a new app or set up a new device.
Frequently Asked Questions
Will turning off an advertising ID stop all tracking?
No. It can limit one way apps use an ID for advertising, but websites, accounts, and other app data may still be used to recognize activity.
Should I turn off location for every app?
Not necessarily. Keep it for features you use, such as maps, but choose access only while using the app when that is enough.
Does private browsing make my activity anonymous?
No. It mainly limits what your browser saves on your device after the session; websites and services you sign in to can still see your activity.
Will changing permissions break my apps?
A feature may stop working if it needs a permission you removed. You can grant that permission again for the app without changing permissions for everything else.
Final Thoughts
You cannot remove every form of tracking with a few switches, but you can reduce unnecessary access. Check ad settings, give apps only the permissions they need, and review the accounts connected to your devices. Small, deliberate changes let you keep useful features without sharing more than you intend.
