Are cookies good for privacy?

Cookies allow websites to store small amounts of data on your device, which can be used to store login information or preferences. However, they also enable companies to track user behavior across multiple visits. Some cookies are more privacy-intrusive than others. For example, session cookies only last while your browser is open and are deleted when you close your browser, whereas persistent cookies can store data for much longer. Additionally, third-party cookies are placed on websites by third-party services/companies. These allow your web browsing to be tracked across multiple sites for advertising and analytics purposes, which raises significant privacy issues.

While cookies themselves are not inherently bad, privacy precautions around invasive cookies are warranted.Companies should implement clear cookie consent banner on their websites to explicitly obtain users’ permission to use cookies on their devices.
