Sounds like option 3: "If this option is supported, Telegram will change its data structure and privacy policy for users from Germany."

I would prefer them to be clearer to say "we will redesign our systems so we no longer store IP addresses".

"Change our data structure" sounds like they might just host the servers outside the country and use a "Telegram Deutschland Inc" company that doesn't have access to any user data to run the service.

Even if they don’t store it: if they get a court order, and it requires to turn on IP logging, they will have yours the next time you log in.

Better than a history, at least.
