Unsure where to post this.
A few months ago I downloaded an app on my mobile that caused excessive data usage (1gb in a hour). I used the mobile to connect my laptop to the internet via USB tether.
At the time I also noted an unusual upload of 16gb, which seemed about the same size as my documents file on my laptop.
I uninstalled the app, and then later reinstalled, and haven't had any further issues with data usage. However I am still concerned that my personal documents may have been uploaded/stolen.
Is there any way to clarify what may have happened? Apart from using a separate computer to access the internet, is there anything else I can do to ensure safety? Thanks.
