If you are concerned about your privacy, you can use an OSS keyboard app. Hacker's keyboard is one for android. There are some on F-Droid. You may even prefer them to Google's offering.
The problem is that even if you install one of those privacy-protecting keyboard apps, chances are that the person you are talking to on the other end is using the stock Google keyboard that sends what they type to Google. Even if only half of the conversation leaks that way, that is still a major blow to the privacy of both parties.
