Whether it's aimed at large companies or not, I'd still rather not see misinformation spread. People already have poor enough understandings of what companies actually do and don't collect. There exists ongoing conspiracy theories that phones actively listen to conversations while in your pocket, despite there being no evidence to such a claim.

Facts do matter, and I appreciate those that make an effort to state them correctly.

Yeah, the facts were stated correctly. They just didn't provide a source. That doesn't make it misinformation. It means it's a claim without a source.

But to answer the question, Gboard absolutely uses your data. And it's right there in its privacy policy.
