How To Clear System Data On Iphone

Download Article

Your iPhone stores a lot of data about what you do. Usually this is used to make things easier for you, such as tracking down a website you've visited or finding a call you missed. If you're worried about someone seeing something they shouldn't, you can clear the history for the various services on your iPhone, or erase everything completely.

1

Open the Settings app (). You'll be clearing your browsing history from the Settings app, not from the Safari app. While you can delete your browsing history in Safari, this won't remove any autofill information or cookies. Clearing your history through the Settings app will ensure that everything is deleted.
2

Scroll down and tap "Safari." You should find this in the fifth group of options.
3
Scroll down in the Safari menu and tap "Clear History and Website Data." A window will pop up asking you to confirm.
- If this button is grayed-out, you'll need to disable website restrictions. Return to the Settings menu and select "Restrictions." Enter your restrictions passcode then tap "Websites." Select "All Websites" to allow clearing history. If you don't have the restrictions passcode, you won't be able to clear the history.^[1]
