Not at all. Most commercial software has a publisher (as legal entity) that is responsible for privacy and takes reputational risks if something goes wrong.

So does this, it says at the bottom "© 2025 Runju Huang". Mister Huang is publishing this, presumably, he would be responsible for any wrong doing.

Is your objection that he is distributing this by himself, instead of through the app store? Or that it appears that he is doing it as an individual instead of a company?

Sure, it's a little sketchy, it's a guy with a website and a privacy protected domain and that's about it. But if anything were to happen you would be suing the developers of refine.sh.

I guess I do see your point though. For my software I have indeed created a legal entity and can be easily looked up.
