Tracker
In Turkish: İzleyici (takip aracı)
A small piece of code in a website or app that records what you do and sends it to other companies, mostly for advertising.
Most websites include trackers from several outside companies. They note which pages you visit, how long you stay and what you click, and link that across sites to build a picture of your interests. Some are in emails too, as tiny images that report when you open the message.
You cannot remove them all, but a tracker-blocking setting or extension and a look at which trackers a site uses reduce how much is collected.
What to do
- Check a site with the MyDefense Tracker Scan.
- Turn on your browser's tracking protection.
- Disable image loading in emails from senders you do not know.
