What are cookies?

A cookie is a small file that a website creates and places on your computer. Cookies are normally helpful and harmless.

Safari helps you identify and manage cookies. When you visit a website that uses cookies, the site asks Safari to store cookies on your computer. When you return to the site later, Safari sends back the cookies that belong to the site. The cookies tell the site who you are so that the site can show you information that’s appropriate for you.

Cookies can store information that identifies you, such as your name and email address. A website has access only to the information you provide. For example, a website can’t determine your email address unless you provide it. A website can’t gain access to other information on your computer.

Safari accepts cookies only from websites you open. This might help prevent certain advertisers from storing cookies on your computer. You can change your cookies preferences so that Safari accepts no cookies or accepts all cookies.
