Best IOS app to share photos

Hello guys. Do you know any IOS app where i can share my photos and can be cool that no one will save them to their gallery or screenshot them, but at the same time i don’t want them to disappear from the app after any amount of time. I used secret chats in Telegram, but realised that i can save photos from there into my gallery, so i don’t like it anymore, and some people can even forward photos from there to other chats
