AirDroid app uses too much data

Hi,
The Airdroid android app is using more data than any other service on my phone (20Mb in 7 days). I have it set to use wifi.
What is using all this data and how can I stop it?

Thanks.

@sherlock2 Your problem has been recorded and our developers are checking on it. Please kindly wait.

It's been over 2.5 YEARS. Are you ever going to fix this problem or is AirDroid a deceased application that should be deprecated?
