Kii Keyboard using data?

view story

http://androidforums.com – Looked at my data usage and it says in the last week Kii Keyboard has used almost 16 MB. Is that normal? Should I uninstall? Has anyone else encountered this? Is this a known issue? I like that keyboard but not if it's eating data. Also, after some further checking it is using 2-3% battery according to Android Assistant. Thoughts? (General)
