Your phone knows where you are or is currently sitting. Most people know that. How else can you use GPS? Although locate tracking is essential for directions, it also helps to sell things with big tech."Targeted advertising" is a huge phenomenon. Companies want to flood your screen with ads that are mainly influenced by your daily habits. Facebook, Apple, Microsoft, Amazon, Google and many others earn money with mobile ads and need this information to power their data mining machines.
Why can your phone track you and share that data with unknown third parties? In short, you gave permission. Typical policies for data sharing are buried on pages and pages of the privacy policy and the terms of agreements. Companies usually have a reasonable explanation, such as Apple who keeps personal calls and e-mails to prevent fraud, which many consider to be a breach of privacy. Regardless of which device you use, you get access to behavior registration via the internet. If this practice bothers you, all hope is not lost.
Here are some ways you can take action:
1. Tweak the location settings of your phone
You can prevent iOS and Android from following you, but this process is not intuitive; the function is buried in privacy settings, and the standard is to record your daily routine. This is known as 'Frequent locations' and keeps track of where you are and how long you stay there. It even knows where you live and work based on how long you are there and how often you go.
If you find this restless, switch off the function. These are the basic steps, but depending on your specific model and operating system, you may have to look around a bit.

Disable location settings on Apple devices: 
1. Click on"Settings" 
2. Go to "Privacy" 
3. Select "Location Services" 
4. Scroll down to "System Services" 
5. Select"Significant Locations" to view the recorded record view from where you have been; switch it off to switch it off. You can also clear your history here by clicking on 'Clear history'.
To change location settings on Android devices:
1. Open the App drawer and go to "Settings"
2. Scroll down and tap "Location"
3. Scroll down and tap "Google Location settings"
4. Tap "Location Reporting" and "Location History" and disable the slider
5. To remove the location cache from your device, tap "Delete Location History" at the bottom of the screen under "Location History"
6. Repeat this process for each Google Account you have on your Android device
2. Limit ad tracking Ending location tracking may sound extreme, so you'd rather fight the ads yourself. iOS and Android also offer built-in options to minimize and minimize ad tracking. These tools will not stop companies from tracking your phone activity, and they will not limit the number of ads you see, but they will allow you to reset your advertising ID and all targeted advertising profiles associated with your specific gadget to disconnect. To limit tracking ads on both iOS and Android: iPhone, iPad or iPod Touch - Go to Settings >> Privacy >> Advertisements >> Switch "Limit ad verification" to On. You can also reset your advertising ID in this section to unlink previous data associated with your ID. Android - Go to Settings >> Google >> Advertisements >> Turn off "Sign out for personalization of ads"
3. Stop Google from following every move Google services have recently come under fire by storing your location data, even if you've adjusted the privacy settings on your iPhone or Android gadgets. Follow these settings to permanently disable Google's location tracking.
Disable Web and app activity:
1. Sign in to your Google account.
2. Click on 'Your personal details' in the 'Personal info and privacy' section.
3. In the left pane, click "Manage your Google activity" and select "Go to activity control." Here you can disable the different types of data that are stored in your Google Account. If you pause "Location History," Google location markers will not be completely disabled. Although Google is not allowed to add your movements to your 'timeline', location data is still stored on your 'Web and app activity'. This fun fact is important. To prevent location markers from being saved, you also have to pause your "Web and App Activity" switch bar. When this feature is paused, the activity of all your Google services will not be stored in your account.
4. Use a private browser on your phone Many computer users are familiar with private web browsers. Less known are the browsers that allow you to search anonymously on the internet on the mobile device. One such app is Mozilla's free Firefox Focus app. This anonymous mobile web browser blocks advertisements, analyzes and social trackers by default. It also clears passwords and browsing history after each session.
The mobile versions of Google Chrome and Microsoft's Edge also have incognito and In Private modes that you can use. If you do not want a mobile browser that is linked to big data brokers, you can use the Dolphin browser from third parties. If you are on a Samsung Smartphone, you can also use the company's Samsung Internet app. This browser has a built-in blocking of advertisements, which prevents other sites from following your online activity. If you do not like Google to include all of your search terms, alternative engines like Yippy, DuckDuckGo and Ixquick will not be that aggressive.
5. Check your online accounts The moment you create an account with a large company (for example Google, Microsoft or Facebook), you start entering data about your location, personality and preferences. Their algorithms follow each click, and data is used for targeted advertisements or 'relevant' messages. Fortunately, these companies and most advertising agencies offer tools to unsubscribe you from personalized ad delivery. For example, Google and Microsoft have account dashboards for privacy checks and to see what it knows about you. Google has updated the ad settings to make it easier for you to understand and restrict ad tracking.
Facebook also has options to disable behavioral tracking to prevent it from following you on the internet. The company is currently also monitoring its third-party apps and they are now more accessible for display and management.
6. Sign out for ads Believe it or not, you have the power to simply opt out of interest-based ads - or at least most of them. The Digital Advertising Alliance has a consumer choice page that lets you see which of the participating partners currently use custom ads on your computer. When you visit the website for the first time, the Alliance will scan your computer. After the scan is complete, a list of these partners is displayed. From there you can learn more about the practices these companies use for interest-based advertising and opt-out using "opt-out cookies" stored in your browser with your preferences. It is important to note that if you do this, not all ads you see online will be deleted. Advertisers can’t offer you targeted ads only.
7. Check your virtual assistants With the rise of virtual assistants such as Siri and Google Assistant, our smart phones are no longer used only for calls and chats. We can now use our voices to manage these gadgets ourselves. However, when you speak the wake-up signals of these virtual assistants, the audio file of your voice command is uploaded and stored on the Apple, Amazon or Google servers for processing. Chances are that this data, as with other tracking information, is likely to be anonymized and go through algorithms that look for behaviors and patterns that can be used for targeted advertisements.
8. Administrative rights for your apps Before you install apps, always check the necessary permissions on their Google Play or Apple App Store page. Android phones also give you an overview of the permission requests when installing an app. iOS apps usually show you a pop-up to access permissions when using a feature that requires specific access to your gadget. Sometimes apps ask for more information than they need. That information can then be sent to companies that might use it for advertising. This is why regularly checking your app permissions is a good practice. Not only will you gain more control over your privacy and prevent apps from spying on and exploiting your spying, but it can also undo apps that are continuously running in the background, which in turn can improve the battery life of your gadget.
