What is a cookie?
A cookie is a small piece of data that's sent by the web server and stored on your device. Cookies contain information about you. For example, your login and password, location, language settings, or the goods added to your basket in an online store.
- Why cookies are useful
- You don't have to re-enter your username and password on a site that requires authorization.
- If you left an online store without placing an order, the goods in your basket are saved for when you return to the store.
- If you specify your city when you first visit a weather forecast site, it won't ask you for your location again.
In web analytics tools (for example, Yandex Metrica) cookies are used to track user activity online.
- Why cookies pose a risk to privacy
- If someone uses your device, and your logins and passwords are saved in cookies, they can access your accounts.
- If a hacker intercepts your cookies, they gain access to your personal data. They can be used to show intrusive ads.
