Cookies are small data files websites store in your browser to track sessions, remember preferences, and enable targeted ads. They explain what data sites collect on you and why—primarily for functionality, personalization, and monetization through tracking—making periodic cleanup vital to curb privacy leaks and security risks like session hijacking.
What Cookies Are and Why They Matter
Cookies store session tokens for logins, user settings like language preferences, and trackers for cross-site ad profiling. Attackers exploit them via malware theft or hijacking, especially old ones from insecure (non-HTTPS) sites, risking identity compromise. Clearing them limits your digital trail and invalidates potential exploits.
Optimal Cleanup Frequency
Clear monthly on personal devices or after sensitive sessions; do it per-session on public PCs. Automate on close for finance pros, striking security-usability balance without endless re-logins.
