Safari’s old Block All Cookies option was designed to prevent websites from storing cookies on your iPhone. Blocking every cookie can interfere with sign-ins, shopping carts, preferences, and other website features, so it is not usually the best everyday privacy setting.
- Open Settings on your iPhone.
- Go to Apps > Safari on current iOS versions.
- Review the privacy and security options available for Safari on your version of iOS.
- Use Safari’s current tracking protections and website-data controls rather than assuming an older Block All Cookies switch is still present in the same place.
What cookies do
Cookies are small pieces of website data used for tasks such as keeping you signed in, remembering settings, and maintaining a shopping cart. They can also be involved in advertising and tracking.
How to remove stored website data
If your goal is cleanup rather than permanently blocking cookies, Safari provides controls for clearing history and website data. You can also use Settings > Apps > Safari > Advanced > Website Data to review or remove stored site data. Menu names can vary somewhat by iOS version.
