How can I make a private, complete backup of my Telegram chats including the secret chats?
I'm about to repair my iOS device which can likely result in factory reset. After repair, it will be still the same physical device, and I'll have a complete iTunes backup of it anyway.
If not possible, how can I export/save history of my secret chat(s) which were started on my iOS device?
Is there any better way of saving than making screenshots? (which is a tedious process, given the size of the history).
I'm using Telegram X client for iOS. I know it's discontinued, but my entire secret chat history is bound to it now.
