What are trackers?

There are proprietary or third-party cookies. The latter are called trackers.

Proprietary cookies are small files that the browser uses to record data about the sites you've visited. Websites use cookies to “recognize” individual users. For example, to avoid asking for their username and password every time they visit the site.

Trackers (or third-party cookies) are small pieces of the website software code. When you open a site, trackers load automatically, collect information (such as location, device type, or IP address), and send it back to their owner. A tracker can be hosted both by the site administrator and by site partners. For example, the site that you're viewing has an ad banner from This banner sends your browser a cookie that stores information about your activity on the site. If you visit another site with an ad banner from, the ad network makes a connection between these visits.

Why are trackers useful?
  • Site owners can use trackers to estimate how many people visit their site, where they're from, and what devices they use. This data can help them optimize the site for audience needs.
  • Trackers let you use the same login or social network widget on multiple sites. For example, you can register on Yandex with the same username and password that you use for VK. When you log in to Yandex, you'll automatically log in to all its services.

Trackers from sites that you visited yourself (such as social networks) are most likely used in good faith.

Examples of malicious use

Malicious tracker owners may collect the personal data that you enter on a website, such as your phone number or email address, and sell it to third parties. As a result, you may receive emails with unwanted ads or get annoying calls from advertisers who you never gave your phone number to.

We consider malicious data tracking to be a violation of your privacy. To protect you, Yandex Browser has developed a special YTP technology that's part of the Protect security system.

What is YTP?

Your Tracking Protection (YTP) is a technology that restricts trackers. By using it, you can choose which resources to trust with your data.

YTP has a simple underlying principle: only the websites that you've visited before are allowed to run trackers. Only these sites can transfer your data from site to site and show you relevant ads. If you haven't visited a website for 45 days, Yandex Browser starts blocking its trackers.

Advertising allows site owners to receive income, and you don't have to pay for viewing their sites. Yandex aims to find a balance between free services and unobtrusive ads.

This way, you can continue using the internet in a way that's convenient for you (such as use the same login on different sites), while websites can support themselves financially without using irrelevant ads that bother users.

Pages where trackers are blocked load much faster.

You can also use the YTP technology to find out what trackers are running on a page and block the ones that you don't trust.

Blocking trackers for all sites

  1. Click   → Settings → Websites.
  2. At the bottom of the page, click Advanced site settings.
  3. In the Cookies section, select what you want to block:
    • Restrict third-party cookies: Only allow them to be used by websites that you've visited before.
    • Block third-party cookies: Block them for all websites.
