We run a public non-logging DNS server with advertising and tracker filtering. The Usable Privacy DNS (updns) service is accssible via DoH and DoT to protect your DNS privacy. Filterlists are based on AdAway and Peter Lowe's list. All upstream DNS queries are resolved encrypted via Digitale Gesellschaft and the Foundation of Applied Privacy.
We do not log client IPs, requested domains or any other personally-identifiable information.
We aggregate information on request types and blocked domains for performance monitoring.
The updns software stack is available under the BSD 2-Clause License on Github:
