Cookies are like tiny memory cards that websites leave in your browser to remember you. Some are helpful (like keeping you logged in), others track your activity. Here's what you need to know:
1. What Cookies Actually Do
How Cookies Work
- You visit example.com
- Website saves cookie in your browser
- On return, your browser shows the cookie
- Site "recognizes" you
// Example cookie content
{
"userId": "123abc",
"lastVisit": "2025-07-11",
"preferences": {"darkMode": true}
}2. Should You Accept Cookies?
✅ Accept When...
- Using shopping sites (needs cart memory)
