Here’s how to clear information from your device:

Delete history, cache, and cookies

• To clear your history and cookies, tap Settings > Safari > Clear History and Website Data. Clearing your history, cookies, and browsing data from Safari won’t change your Auto Fill information.
• To remove other stored information, tap Settings > Safari > Advanced > Website Data > Remove All Website Data.
• When there’s no history or website data to clear, the setting turns grey. The setting might also be grey if parental controls are set for websites. To check your settings, go to Settings > General > Restrictions, then scroll to Allowed Content.

  Block cookies

  A cookie is a piece of data that a site puts on your device, so it can remember you when you visit again. Here’s how to choose whether Safari blocks cookies:

  1. Tap Settings > Safari > Block Cookies.
  2. Choose an option: Always Block, Allow from Current Websites Only, Allow from Websites I Visit, or Always Allow.

  If you block cookies, some web pages might not work. Here are some examples:

  • You might not be able to sign in to a site using your correct username and password.
  • You might see a message that cookies are required or that your browser’s cookies are off.
  • Some features on a site might not work.
    

    Use content blockers

    With iOS 9 and iPhone 5s or later, you can use content blockers in Safari. Content blockers are third-party apps and extensions that let Safari block cookies, images, resources, pop-ups, and other content.

    Here’s how to get a content blocker:

    1. Download a content blocking app from the App Store.
    2. Tap Settings > Safari > Content Blockers, then set up the extensions that you want. You can use more than one content blocker.
