Why this matters for digital sovereignty
Privacy-friendly DNS services see every domain you look up and can therefore reconstruct your entire browsing pattern, which makes hosting location and vendor ownership relevant. Check whether the service maintains a no-logs policy, where its servers are located and whether self-hosting the DNS resolver is an option.
