Does Yuzu connect to the official Nintendo servers?

Is there an official statement on whether Yuzu connects to the official Server for feedback/telemetry/multiplayer/… or not?

Or in other words, is there a ban risk when using the emulator, or is it local only?
(I assume that dumped games still contain details from the real switch they came from)

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

There’s no online service implemented, and outside of maybe local wireless in the future, there will never be.
Ban risk is 0.

Great to know, thank you.
