jack.bio is the personal website of Jack LaFond, a security researcher based in Tampa. The site serves as a portfolio of his projects, blog posts, and resume. Since it's a personal blog rather than a store or service, the lack of a privacy policy or terms of service is expected β you wouldn't ask a friend's homepage for those. What matters more is that the domain has been active since at least 2021 and has never shown up on any blacklists or Google's safe browsing warnings. That's a good sign.
One technical note: the site still accepts older, insecure versions of TLS. It's a minor vulnerability, but for a site that doesn't handle logins or payments, the risk is low. If you're just browsing his articles or checking out his tools, there's no reason to be wary. jack.bio reviews from the community are positive, and the contact info and social links add transparency. So is jack.bio a scam? No, it's a legitimate personal blog from a known individual.
