It does say that they collect this information in their “Data and Privacy Policy”. Specifically section 2.2 (Data Collected): https://quad9.net/privacy/policy/
Which policy are you referring to that implies they don’t?
Also I think you are assuming they store query logs and then aggregate this data later. It is much simpler just to maintain an integer counter for monitoring as the queries come in, and ingest that into a time series database (not sure if that’s what they actually do). Maybe it needs to be a bit fancier to handle the cardinality of DNS names dimension, but re-constructing this from logs would be much more expensive.
The section you mentioned does not say anything about having counters for labels. It only mentions that they record "[t]he times of the first and most recent instances of queries for each query label".
Well, the counters aren't data collected, they are data derived from the data they do collect. The privacy policy covers collection.
EDIT: I see they went out of their way to say "this is the complete list of everything we count" and they did not include counters by label, so I see your point!
I don't see how that is compatible with 2.2. They don't say anything about counters per label. It says counter per RR type, and watermarks of least and most recent timestamps by label, not count by label.
If an organization is going to be this specific about what they count, it implies that this is everything they count, not that there may also be other junk unmentioned.
