It's free for now. I wanted first to see if there is an interest. The product is open source, so it'll be free forever anyway. I like the GitLab approach - free for everyone, but perhaps put some way to monetize this. I just have NO idea how. I honestly didn't think about it, because I wanted to have a side project that would be useful for people, and I don't know if people need this.
I think some may fear it for one of the natural monetization routes for a product like this, selling the personal info to marketers, intel-companies, credit agencies, etc.
