Consuming waaaaaay too much data

[crearo]

Apparently the app is consuming waaay too much data - over 400MB in 10 days according to some. Look into this.

Every refresh costs around 200kB - depending on how many emails your inbox has.
So at the most, in an hour with 3 refreshes per hour, a maximum of 1 MB can be consumed - per day ~25MB if you're online the whole time.
