Hey Stennie 
Thanks for the reply!
the first link if you enter “realm self hosted”, is this one: https://docs.realm.io/sync/v/3.x/self-hosted and on there there is nothing about deprecation, so its not some burried document, but the main documentation on your site. I hope you can fix this, since it did cost us quite some time now, and does not breed confidence in the company if the official docu is out of date 
Regarding my concerns towards data privacy and protection, they are less concerns than they are simple laws, you cannot, without legal binding contracts and agreements like a DPA be a data processor for another company under current law in most countries, which no matter if realm is setup technically well, and also is willing to sign those contracts, is putting a hurdle on people to use your, really nice and cool, product.
ad my support ticket, yes I got an initial answer, asked another question and then did not hear back for my follow up question.
Since self hosting is something you don’t want to offer, and any contract work usually takes some time & hustle, and we are currently in the prototype phase with a new idea, I am not sure if going with firebase, parse, etc. is maybe a more viable option. I think realm is the better product, but the legal hurdles you put in place for use-cases like ours, are maybe enough reason to exclude you since we cannot do this kind of paperwork for every prototype, and thus it won’t lead us to using it in production. Which I find sad, since I really enjoy the platform.
Best,
Lukas
