What I really want is an app that goes through all my photos/chat history and deletes anything that might contain sensitive information after 30 days, such as from screenshots. I already use the iMessage feature that lets you delete history after 30 days, but I wish I could pretty much do this for everything. There are some things I might want to keep (like photos, for example), but I'd prefer to just have anything private deleted automatically. If it's information I really want to save, I'll make sure to save it somewhere safe.
