Our ongoing commitment to privacy for the 1.1.1.1 public DNS resolver

Eight years since its launch, Cloudflare's 1.1.1.1 public DNS resolver remains committed to being the fastest and most private service, underscored by a recent independent audit confirming its privacy promises. Initially reviewed in 2020, Cloudflare has again undergone an extensive examination by a Big 4 accounting firm to ensure compliance with its privacy commitments, reaffirming that it does not sell or share users' personal data or target users with ads. The audit highlights that source IP addresses are anonymized and deleted within 25 hours, with randomly sampled network packets used solely for troubleshooting and attack mitigation. The audit focused exclusively on privacy commitments, whereas previous reviews included broader operational practices. Cloudflare emphasizes its dedication to privacy, advocating for industry standards that protect users' online movements, and assures that DNS query data from 1.1.1.1 will not be combined with other data to identify users. The detailed results of the audit are available on Cloudflare's compliance page, reinforcing its role as a privacy-first DNS resolver.
