That is not possible, either those games were not made using renpy or they would have asked. Also, as I mentioned before - the game is not ported by me, it is ported by DarkAssassin, you can check his website or connect with him on Discord for any technical issues - https://darkassassinda.wixsite.com/daports

I pressed on the "more information" tag in the site to check out other games made with Ren'Py.
1st game that popped up was "The Freak Circus", that game didn't ask me for any permissions (gallery access or otherwise) after I downloaded and opened it.
I don't know why you say it's not possible, but it is.
I'll check the link you sent me.
