Do I need to publish to an app store?

No. Users install from the website itself: Add to Home Screen on iOS, Install on Android and desktop Chrome/Edge. No review, no fees.

Yes. No account, no card, no watermark. Each visitor can run a tool a few times an hour; the limit exists only to keep the tools fast for everyone.

What happens to what I type?

Your input is sent to an AI model to produce the result and kept with the result for 90 days so you can come back to it. It is not used to train anything, and result links are unlisted.

Can I use the result outside Chattee?

Of course. Copy it, download it, share the link. "Build this with Chattee" is there if you want the app built, not a condition.
