How to un-sync the browsing history on your iPhone from your iPad or other iDevices
However, this is not always a convenient thing. After all, you probably won't carry both devices with you at all times, or you could just be using them for very separate purposes, so having them completely in sync is not always the best option. Thankfully, Apple is aware of that, and has given users the option to keep an iDevice's Safari browsing history and bookmarks off of the iCloud. If you happen to have all your devices synced currently, the following guide will show you how to get Safari off the cloud, and how to delete all browsing history, should you need to do that.

1: Go into Settings
2: Tap on your Apple ID banner at the top of the menu
2: Scroll down and find "Clear History and Website Data"
