The in-app assistant can talk with users. It is software, not a person at the studio, and not a stand-in for professional advice. Legal, medical, and financial questions are outside what it may settle. If a reply sounds certain, that tone is not a license, a diagnosis, or a plan you should treat as counsel.
What someone writes is used only to answer them. The words are not handed to other users, not posted to a shared board, and not saved as a portrait of the writer. The apps build no personal profile. There is no name, email, phone number, contact list, or precise location gathered to describe a person.
Users do not send personal data to each other through these apps. Two people can use the same product and still have nothing to exchange. The only identifying item in the product is a unique id, and it exists for attribution and push, not for introducing one user to another.
