Privacy-first design

• IP masking — built-in functionality masks Layer 3 IP addresses (IPv4 and IPv6), which prevents tracing DNS queries back to individual users.
• Local deployment — dnsmonster runs inside your own infrastructure. You have complete control over what is collected and how it is stored.
• No data collection by us — the dnsmonster developers do not collect, store or have access to any data processed by your installations.

Your responsibilities

When deploying dnsmonster, you are responsible for:

• complying with applicable privacy laws and regulations in your jurisdiction
• implementing appropriate data retention and deletion policies
• ensuring proper access controls to DNS data
• obtaining the necessary consents for monitoring DNS traffic
• configuring IP masking and other privacy features appropriately

Changes to this policy

This privacy policy may be updated from time to time. Changes are reflected in the documentation repository.
