Clear Private Data, Empty Caches, and Remove Cookies in Safari

To remove your browsing history across synchronized devices and computers, cookies, caches and other website data from Safari after visiting an email service on the web from, perhaps, a public computer:

  1. Select Safari > Clear History from the menu in Safari.
  2. Select the desired time period—the last hour and today are typically most appropriate—under Clear.
    1. You can also choose all history, of course, to delete all data.
  3. Click Clear History.

Note that this will remove that data from iCloud and all Safari browsers on other computers and devices as well, if you use iCloud to synchronize browser data.

Clear Data (but Not History) for Specific Sites in Safari

  2. Go to the Privacy tab.
  3. Click Details under Cookies and website data.
  4. Find all sites (by domain name) that store data via cookies, a database, the cache or files.
  5. For each site whose data you want to remove:
    1. Highlight the site in the list.

    2. Click Remove.
  6. Click Done.
