Your browsing habits: Trackers keep records of what websites you visit, how long you visit for, and what you purchase. They may also record what ads you tend to click on; it all helps to build an advertising profile.
Safari employs a feature called Intelligent Tracking Prevention which uses machine learning to determine which websites can track you across the internet. The browser will block and delete third-party trackers from sites you haven't visited over the last 30 days.
When you enable the toggle to prevent cross-site tracking on Safari, you will be protected against profiling. Therefore, your data will not be accessible for these trackers and hence, Safari will put out the number of trackers it has prevented from profiling you.
I would highly recommend you do so, in order to prevent companies from tracking you and using that data for targeted ads and keep tabs on how you interact with their sites.
It will be easily accessible by the criminal without the careful handling of your data. The worst of it is getting your money in a blink of an eye, usually in bank transactions. Others tend to uncover the hidden secrets and private pictures.
Stalkerware (and spyware) can monitor your device for data such as your location, which URLs you've visited and which apps you've recently run. It can even log keystrokes, giving away information about anything you've typed into your phone, including passwords.
Does Safari block all trackers? By default, Safari limits the number of third-party trackers. To block all trackers, you have to go to Settings → Safari → Block All Cookies. However, this might affect your browsing experience as some websites require cookies and trackers to function effectively.
For a Privacy Report that shows a list of known trackers who've been blocked from tracking you, choose Safari > Privacy Report. To start blocking trackers, see Prevent cross-site tracking.

The best way to block phone tracking is to use a VPN. But you can also change a few settings on your phone or switch to a different browser to stop tracking. You can hide your location via settings, block ad tracking with a dedicated private browser, and encrypt all of your internet traffic with a VPN.
However, if someone is spying on your phone, there are common signs you can look out for. You may notice a rapid increase in your phone's data usage, suspicious files or applications, or strange text messages that you don't remember sending. Your device may also show signs of malfunctioning behavior.
Go to Settings > Privacy & Security > Tracking. The list shows the apps that requested permission to track you. You can turn permission on or off for any app on the list.
To prevent this, whenever you visit a website, Safari presents a simplified version of your system configuration. Your Mac looks more like everyone else's Mac, which dramatically reduces the ability of trackers to uniquely identify your device.
Major Updates to Safari Private Browsing
Advanced tracking and fingerprinting protections go even further to help prevent websites from using the latest techniques to track or identify a user's device.
If you delete all your Safari cookies, you can reduce tracking from third-party sites and you'll likely see fewer targeted ads. But beware, clearing your cookies may also log you out of websites and make you log back in again.
For Android devices, there is usually no need for such a process. All a hacker would need to do is essentially tweak a few settings. For example, if they simply disabled Google Play Protect, then they would be able to install the spyware hassle-free.
