Disagree that it's fairly close to the statement "they resell traffic logs" and the implication that they leak all queried hostnames ("secret hosts, like for your work, will be leaked"). Unless Quad9 is deceiving users, both statements are, in fact, completely false. https://quad9.net/privacy/policy/#22-data-collected https://quad9.net/privacy/policy/#22-data-collected

>and the implication that they leak all queried hostnames ("secret hosts, like for your work, will be leaked"). The part about sharing data with "a very few carefully vetted security researchers" doesn't preclude them from leaking domains. For instance if the security researcher exports a "SELECT COUNT(*) GROUP BY hostname" query that would arguably count as "summary form", and would include any secret hostnames. >https://quad9.net/privacy/policy/#22-data-collected https://quad9.net/privacy/policy/#22-data-collected If you're trying to imply that they can't possibly be leaking hostnames because they don't collect hostnames, that's directly contradicted by the subsequent sections, which specifically mention that they share metrics grouped by hostname basis. Obviously they'll need to collect hostname to provide such information.

  I'm implying that I'm convinced they are not storing statistics on (thus leaking) every queried hostname. By your very own admission, they clearly state that they perform statistics on a set of malicious domains provided by a third party, as part of their blocking program. Additionally they publish a "top 500 domains" list regularly. You're really having a go with the shoehorn if you want "secret domains, like for your work" (read: every distinct domain queried) to fit here.

By your very own admission, they clearly state that they perform statistics on a set of malicious domains provided by a third party, as part of their blocking program. Right, but the privacy policy also says there's a separate program for "a very few carefully vetted security researchers" where they can get data in "summary form", which can leak domain name in the manner I described in my previous comment. Maybe they have a great IRB (or similar) that would prevent this from happening, but that's not mentioned in the privacy policy. Therefore it's totally in the realm of possibility that secret domain names could be leaked, no "really having a go with the shoehorn" required.
