Prevent cross-site tracking

Some websites use third-party content providers. A third-party content provider can track you across websites to advertise products and services.

With this option turned on, tracking data is periodically deleted unless you visit the third-party content provider.

Block all cookies

Don’t let any websites, third parties or advertisers store cookies and other data on your Mac. This may prevent some websites from working properly.

Manage Website Data: See which websites store cookies and other information on your Mac. Remove cookies and website data for individual websites or all of them.

Allow websites to check if Apple Pay is set up

When you are on a website that uses Apple Pay, the website can check if you have Apple Pay set up on that device. If you are using a Mac to which a card cannot be added, the website can check if you have Apple Pay set up on an iPhone or Apple Watch. You can disable websites you visit from checking if Apple Pay is set up at any time by deselecting “Apple Pay: Allow websites to check if Apple Pay is set up” on your Mac in Safari > Preferences > Privacy.

This option appears if you have either a:

Mac with Touch ID.
iPhone 6 or later (including iPhone SE) with iOS 10 or later, or Apple Watch with watchOS 3 or later. You must be signed in to iCloud using the same Apple ID on your device and your Mac (and your Mac must support Handoff).

If you allow websites to check if Apple Pay is set up, one of two things can happen:

If you have a card set up in Apple Pay: Websites might default your shopping cart to Apple Pay and you might see the Apple Pay button on product detail pages (it’s up to the website).
If you don’t have a card set up in Apple Pay: Websites probably won’t default your shopping cart to Apple Pay and you probably won’t see the Apple Pay button on product detail pages (because the website can see that you haven’t set up a card).
