Telegram is very clear that they do store our stuff on their servers. And in clear text unless you choose end-to-end encryption.

My concern is not about my data being stored on their servers. My concern is about having having marketing data being sold to third parties in order to target advertising at me, just as when you leave "third party cookies" active on your browser. That is creepy and invasive. Would Zuckerburg ever do such thing?
