Does this online meter transfer data to the server?

No, all audio data is being used locally.

What mode does this meter have?

It has the ITU-R BS.1770-4, or dB A-Weighted mode.

How accurate is this meter compared to other professional SPL meters?

Analyzing from the microphone will not give you accurate SPL-Loudness values since it is limited to the hardware on which it is being used. If you want to know the exact SPL-Loudness level please use professional hardware made for that use. However, if you want to compare the perceived loudness of two different sounds this meter will do a great job.
