Link to download apk options page in my website

Hello, I have an app on Play Store with ads. Also due to Google Policy it does not contain adult content. I have same version of the app without ads, and another with adult content. I want to let user download apk directly from my website and advise users of these options inside the app on google play.
Is it legit for Google? Specifically I would like to implement it in settings page, adding a button like “Check other download options on our webiste”

Hi, i was also thinking about this. Does anyone know if Google allows it?
