Privacy Policy

Summary

DNS queries together with the originating client IP address are stored for, at most, 24 hours until the logs are automatically purged. This is done to protect against DNS amplification attacks by using fail2ban. Fail2ban is a automated tool that do process the DNS query log file to listen for attacks, and requires no human intervention. The DNS query log, that also contain the originating client IP address, is automatically rotated and purged at midnight every day.

All our DNS servers do use the pi-hole privacy level: Anonymous mode: This disables basically everything except the live anonymous statistics. No history is saved at all to the database, and nothing is shown in the query log. Also, there are no top item lists.“. Note that the DNS queries are still stored in the query log for, at most, 24 hours in order to use fail2ban as explained above.

pi-dns will never go through, sell or share your dns query data with any third parties. We have no desire to impose on anyone’s privacy.

How can I verify the anonymous mode of the DNS servers?

Each DNS server expose an API available to everyone. This API is the standard API that ships with the pi-hole web service and have not been modified in any way. The response contains a parameter privacy_level and can be set to any of the following values depending on the pi-hole privacy setting:

0: Show everything and record everything, Gives maximum amount of statistics.
1: Hide domains: Display and store all domains as "hidden", This disables the Top Domains and Top Ads tables on the dashboard.
2: Hide domains and clients: Display and store all domains as "hidden" and all clients as "0.0.0.0", This disables all tables on the dashboard.
3: Anonymous mode: This disables basically everything except the live anonymous statistics, No history is saved at all to the database, and nothing is shown in the query log. Also, there are no top item lists.
4: No Statistics mode: This disables all statistics processing. Even the query counters will not be available.

It’s therefore possible for everyone to visit this API and inspect the privacy_level parameter. The API endpoints can be found at:
