If you’re like most people, you probably use iCloud to keep track of your personal information and settings. But if you want to delete any of your word history on your iPhone, there’s a few steps you need to take. First, open up the iCloud app and sign in. Then, click on the three lines in the top left corner of the main screen and select “Delete All.” After that, type your password into the bottom right corner and hit “Delete.” If all goes well, your word history will be deleted and all of your data will be backed up in iCloud. If something goes wrong - for example, if you forget your password - then you’ll need to go back into the iCloud app and select “Restore All” to get everything back as it was before.
