What do cookies know about you and should you be afraid of them?


Have you seen the notification “We usecookie" when they visited some new site, but how it works, why advertisers love these "cookies" so much and what innovation Google is planning, experts from the Center for Digital Expertise of Roskachestvo told.

Cookies know and "remember" a lot:
● your IP address and location;
● when, what time and from what device you accessed the page;
● preferences (language, font size, etc.);
● viewed products in the online store;
● text entered on the site;
● what you clicked on and what you searched for.

Large advertisers like Meta and Google throughCookies collect analytical information about users' actions on the site to create targeted advertising. Thus, on the same site, each person will see their ads. Someone is about new sneakers, and someone is about vocal courses.

Is there a danger?
Cookies themselves are not dangerous and do not belong topersonal data. Only part of the cookie is stored on the user's computer. But if third-party frames from the site are integrated there, then with their help complete surveillance of the user is possible.

Google said last year that it no longer wantedviolate user privacy related to cookies, so it is testing new technologies to replace it. In particular, the FLoC web standard for the Chrome browser is considered.

That means new technology will make life harderthird-party companies to obtain information about users to create a target in Google products. Companies simply won't be able to embed their frames in cookies on the site. As a result, all data will go to one source - Google. Thus, she guarantees herself the further sale of targeted advertising. You can't say it's bad. This is the reality of the market. For example, Apple does the same thing and calls it promoting online privacy.

Sergey Kuzmenko, Senior Digital Product Testing Specialist of Roskachestvo: “Whatever web standards are applied,targeting will still use user data in many ways, which means there will always be options for abuse, as was the case with cookies. Users can control how cookies are used on individual websites. Most modern browsers allow you to delete cookies. Over time, they accumulate and can take up gigabytes of hard drive space. We recommend cleaning cookies manually every 2-3 months. Select sites that you rarely visit and delete cookies there. Still, you should not completely disable them, otherwise setting up personal site parameters and logging in to accounts will be difficult.”
