how to delete purchase list
can i delete purchase history or not ?
iPhone 6s, iOS 15
You can't delete items from your purchase history but you can hide them.
For apps, see this document: Hide purchases from the App Store - Apple Support .
It only mentions hiding apps but according to Apple (as Recommended in: how do i delete an expired subscription - Apple Community ) subscriptions get hidden too.
Read this document about hiding music, movies, TV shows, audiobooks, and books - Hide and unhide music, movies, TV shows, audiobooks, and books - Apple Support
This doesn't remove the item in your purchase history but Family Sharing members won't see them and they won't appear in your Library on a device unless you downloaded it to a device.
