Google Keyboard updated with personalized suggestions
You had to know that this was coming at some point. Google didn't push its own keyboard app into the Play Store simply to add gesture typing. The plan was likely always to make the Google Keyboard more Googley, and today starts the rollout with that update. Google has begun a rollout of an update to its keyboard which adds personalized suggestions.
You can turn off this feature and delete the data Google has gathered to power this feature if you want. If not, your keyboard should get quite a bit smarter in a very short period of time, assuming you have used other Google services enough. And, as always, if you don't like the privacy implications of this feature, and turning it off and deleting the data isn't enough for you, there are plenty of keyboard alternatives in the Play Store that you can grab instead of Google's offering.
The update will be rolling out over the next few days, but if you want to sideload the update, you can grab the APK at the source.
