So, on steam, the game requires you to accept 3rd party terms of services, which in themselves contain a link to the privacy policy. In both, things are held vague as it applies to all relic games, but things include account linking, which is a kind of drm gog now seems to support (on some products such as the new edition of Hexen/Heretic), collection and sale of private data (unless you somehow obscurely object from some countries), automatically installing third party anti-cheat software, etc... the usual package with games nowadays.

I find no mention of this on gog. So do the terms of service differ for relic products such as this bought on gog or is this just something gog isn't telling you? I'm confused on what the actual terms for the product are.
