Does Cloudflare DNS sell data?
Cloudflare will not sell or share public resolver users’ personal data with third parties or use personal data from the public resolver to target any user with advertisements.
Cloudflare will only retain or use what is being asked, not information that will identify who is asking it.
Except for randomly sampled network packets captured from at most 0.05% of all traffic sent to Cloudflare’s network infrastructure, Cloudflare will not retain the source IP from DNS queries to the public resolver in non-volatile storage (more on that below).
The randomly sampled packets are solely used for network troubleshooting and DoS mitigation purposes.
A public resolver user’s IP address (referred to as the client or source IP address) will not be stored in non-volatile storage. Cloudflare will anonymize source IP addresses via IP truncation methods (last octet for IPv4 and last 80 bits for IPv6). Cloudflare will delete the truncated IP address within 25 hours.
Cloudflare will retain only the limited transaction and debug log data (“Public Resolver Logs”) for the legitimate operation of our Public Resolver and research purposes, and Cloudflare will delete the Public Resolver Logs within 25 hours.
Cloudflare will not share the Public Resolver Logs with any third parties except for APNIC pursuant to a Research Cooperative Agreement. APNIC will only have limited access to query the anonymized data in the Public Resolver Logs and conduct research related to the operation of the DNS system.
