Telegram stores all data on own servers.

Just try the following trick:

- in a private Browser window open web.telegram.org

- enter your phone number, receive the code

- turn on flight mode on your phone

- now enter the identification code in your browser

- access your whole chat history while your smartphone can definitely not act as a source

Even WhatsApp is better in this regard.

What's this supposed to prove?

that it stores all of your messages on a server, and not on your phone. Your phone being in plane mode disconnects it from the internet, but you are still able to browse your messages.

You don't need to 'prove' it. Thats their selling point. Access your messages on every platform.

Isn't it as they describe it? Unless you created e2e chats specifically (Secret Chats).
