I see you missing the point here. As a consumer, I don't want to be your customer.
When I buy stuff at the grocery store, I'm not the customer of the companies that produce food. Similarly, I just want to get your app, not become a marketing target for dozens of software vendors with varying privacy and data retention policies. I don't want you to upsell me on anything, it's literally the opposite of friendly to me as a consumer.
