Cookies are tiny text files that a website places on your computer. They act like a name tag so the site knows it is still you when you move to a different page.

Digital Crumbs called Cookies

Your browser automatically sends your cookies back to the website every time you visit. This is how a site knows you are already logged in without you having to type your password again.

Automatic Delivery Service

Some cookies vanish the moment you close your browser, while others have an 'expiration date.' This determines if a site remembers you for just one visit or for many months.

Temporary vs Permanent Cookies

SessionStorage is a special closet that only lasts for as long as a specific browser tab is open. If you close that tab or window, the information is instantly wiped away.

The Single Tab Storage

Cookies are like a small wallet that can only hold a few cards, while LocalStorage is like a large suitcase. You use cookies for small IDs and LocalStorage for bigger things like saved drafts or themes.

Comparing Storage Space

The website's computer can see your cookies directly, but it cannot see your LocalStorage. This makes LocalStorage faster for the browser to use, but it requires a different method to share that data with the site.

Website vs Browser Access

A 'Session' is like a temporary ticket the website gives you when you log in. As long as you show this ticket (usually hidden in a cookie), the site lets you stay in the 'members only' areas.

The Concert Ticket Trick

Because these storage spots are on your device, sensitive data like credit card numbers should generally not be kept there. Hackers sometimes use sneaky tricks to try and read this data.

Keeping Information Safe

You can manually delete cookies and local data through your browser settings. This is like hitting a 'reset' button that makes websites treat you like a brand-new visitor.
