Hey, founder of Sagefy here. Thanks for the reply :)
Currently Sagefy is a side project, so there's no income to speak of. There's some ideas I've had around potential revenue streams, but I want to avoid needless tracking, third party advertising, and pay walls. It's a ways down the road regardless.
I'm not a lawyer so I can't speak to GDPR, but there's a list of everything its currently using: https://docs.sagefy.org/technology-stack
Sagefy does not sell or rent data. https://sagefy.org/terms
