What is the primary use of cookies in privacy practices?

• A. To replace the need for user consent.
• B. To identify returning users and collect preferences.
• C. To store payment data securely.
• D. To encrypt data in transit.

Answer: (B)

Cookies are small text files stored in a user’s browser that help a website recognize the same user over time and remember choices the user has made. This capability is what lets a site identify returning users and collect preferences such as login status, language, or theme settings, so the experience can be personalized without starting from scratch each visit. Cookies aren’t about replacing consent—consent governs whether cookies can be used—nor are they a secure place to store sensitive data like payment details, which should be handled by dedicated secure systems. Encryption in transit is separate, protecting data as it travels between the browser and server, not by cookies themselves. So, the main use in privacy practices is to identify returning users and collect preferences.
