I just noticed that whenever my WiFi is on this icon appears in between. I searched about this icon and I got information about it which says that this icon appears when "WiFi connection is being used to transfer data". Now I am little confused/ scared that if someone is transferring my mobile data using WiFi connection. I am not downloading or uploading any data and it still shows this icon. Kindly help me in clearing my doubts about this. Thanks in advance. Cheers 😃
There are a lot of background tasks to use the network
To name few:
- Store checking (and downloading) app updates
- E-mail sync
- Other services you use to sync your stuff (OneDrive, DropBox, etc...)
- Apps that run in background (such as Skype, Hike, WhatsApp, etc...)
- Automatic OS updates
- Sending of Feedback data
To answer your question

In Windows 10 Mobile Go to Settings->Network & Wireless->Data Usage. Check if data usage is allowed on Limited WiFi. Click Don't Allow button.
In Windows Phone 8.1 or lower, Go to Settings -> Cellular network. There is option "during limited WiFi connection" - make sure you have option "do not use cellular data" checked.
Also, your personal data are never transferred unless you specifically say so.
