Concerns about the legitimacy of Phalanx International Limited's App Store presence

I am questioning the legitimacy of Phalanx International Limited.

Their website says: “Phalanx is a platform that distributes entertaining and engaging stories across social media. We help content creators by providing a robust set of monetization and content distribution technology.”

but they make an “AI Assistant: Integrated Clean” and “Heart Ease: blood pressure log”

the Privacy policy link on the App Store points to various generic boilerplate/ template policies without any contact information.

in replies to Reviews they answer “Hello dear, …” not very professional. Also they say “boarder” instead of “broader” in two replies.
