Uploading the tool made on infinityfree to Play store legal?

I’m guessing that the “turn a website into an app” tool is just “build a small shim app with a WebView component that loads the website”. Which is fine by itself since you’re basically just slapping a different name and icon on a stripped-down web browser. However, I do vaguely remember that WebView components don’t play well with our bot protection system, so I’m not sure if it will work. As for the PDF conversion functionality, that’s a bit of a grey area because PDF conversion is more compute expensive than regular web activity. But the account CPU limits should help keep that in check. File hosting is also a bit of a grey area, but if it’s temporary, I don’t see any major issues with that either. All in all, I would say it’s safe enough to try, but do test the app beforehand because I’m not sure if it will work.
