> Although this automatic data transmitting function is switched off in the default setting, Sugiura found that Baidu IME secretly sends users’ information even when the function is turned off.
Simeji, on the other hand, is a bigger concern - it's a very popular Japanese keyboard for Android.
Either way, this is one hell of an information leak if the keyboard app is sending everything you type in somewhere else.
Simeji was originally created by an indie dev, but then Baidu bought the app.
But in general, nearly all non-geeks stick to what came with their OS.
1. It's a cloud based IME. Some data is uploaded to improve user experience.
2. Data upload is encrypted therefore no privacy concerns.
3. Servers are located in Japan and complies with local regulations.

edit: Found the "language" option on Google sign-in -- it's the scroller in the bottom right labelled "日本語". There's a small blue logo next to it that looks like the UN flag. Hope this helped someone.
edit #2: It's also in the URL, replace /intl/jp/ with /intl/en/ (for English)
I think users without prior IME experience may have a hard time image what is the purpose of sync or what does it do. It's a user trained Bayesian db where you can input your most used words/combinations very fast.
It's like auto-complete in IMEs or Google Suggest where you can get a list of "hints" ordered by popularity.
Baidu IME does the same, except, according to OP:
