Deleting your App Store history can help protect your privacy and keep your device running smoothly. When you delete your history, Apple will remove all of the apps that you have downloaded, as well as any reviews or ratings that you have left. This can be helpful if you are selling or giving away your device, or if you simply want to start fresh.
To delete your App Store history, open the App Store app and tap on your profile picture in the upper-right corner. Then, tap on “Purchased” and then on “My Purchases.” From here, you can tap on “Clear” to delete all of your history.
