How to clear my iCloud/Apple subscription history for apps on iPhone 13

I see you are asking about how to "clear" your subscription history. You are not asking about how to cancel a subscription.

You can't delete subscriptions from your purchase history but you can hide them. See this document: Hide purchases from the App Store; click here --> Hide purchases from the App Store - Apple Support . Confusingly 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.

To end your subscriptions go to settings>your name>subscriptions

to end your iCloud + suscription go to settings>iCloud>downgrade your storage
