Windows Phone Cortana in India

After applying WP8.1 GDR1 (Developer Preview), Cortana is available in India. But to use Cortana, we need to configure Speech language as English UK (or English US).

Cortana is not able to respond any voice commands. Perhaps it is not yet able to recognize Indian accent.

Below are some screenshots taken from Cortana.

What information is Cortana gathering in non-US region Windows Phone?

I am running WP8.1 Developer's Preview OS on my Lumia 620. I have set my phone for India region, and never changed to US region to check Cortana or any other features.
Yet today while checking Data Sense, I saw that few data was consumed by Cortana as "Cortana: Info gathering".

Just wondering what information could be Cortana gathering. Hope its not spying on my phone ;)
