Privacy Policy

Last updated: January 2026

At ClearDNS, privacy is not just a feature - it's our foundation. We've built our service from the ground up to minimize data collection while maximizing your protection online.

Our Privacy Philosophy

ClearDNS operates on a zero-knowledge principle. We believe that effective DNS filtering doesn't require knowing who you are. Unlike traditional services that require accounts, emails, and passwords, ClearDNS works without any personally identifiable information.

What We Don't Collect

Let's start with what we intentionally avoid:

• No account information: We don't require or store emails, usernames, passwords, or any registration data.
• No personal identifiers: We don't track your name, address, phone number, or any other PII.
• No query logs by default: Your DNS queries are processed in real-time and discarded immediately. We don't maintain logs of the websites you visit.
• No browsing history: We cannot and do not build profiles of your internet activity.
• No cross-device tracking: Each device configuration is independent and not linked to any identity.
• No third-party analytics on DNS: Your DNS queries are never shared with advertisers, data brokers, or analytics companies.

What We Do Process

To provide DNS filtering, we necessarily process:

• DNS Queries: When your device makes a DNS request, we receive the domain name being queried. This is processed in real-time to apply your filter settings and is not stored.
• Filter Configuration: Your chosen filter categories (ads, malware, adult content, etc.) are stored in an anonymous configuration linked only to a randomly generated device identifier.
• Anonymous Device Tokens: Each device receives a unique, random token that identifies its filter configuration. This token contains no personal information and cannot be traced back to you.

Optional Query Logging

For users who want visibility into their DNS activity (such as parents monitoring children's devices or users troubleshooting), we offer optional 90-day query log retention as an add-on feature.

• This is strictly opt-in and disabled by default
• Logs are stored encrypted and associated only with your anonymous device token
• You can delete your logs at any time
• Logs are automatically purged after 90 days

Infrastructure and Security

ClearDNS infrastructure is designed with privacy in mind:

• DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT): All DNS traffic is encrypted, preventing your ISP or network operators from seeing your queries.
• Distributed Processing: We use Cloudflare's global network for DNS resolution, ensuring fast responses and robust security.
• No Persistent Storage: DNS queries flow through our system without being written to permanent storage.
• Regular Security Audits: Our infrastructure undergoes regular security reviews.

Website Analytics

Our marketing website (cleardns.com) may use analytics to understand how visitors interact with our site. This is separate from our DNS service and does not affect your DNS queries in any way.

Third-Party Services

Our DNS filtering service runs on Cloudflare Workers infrastructure. Cloudflare processes DNS requests on our behalf but does not have access to your filter configurations or any identifying information. For Cloudflare's privacy practices, please refer to their privacy policy.

Data Retention

• DNS Queries: Not retained (processed in real-time only)
• Filter Configurations: Retained as long as the device token is active
• Optional Query Logs: 90 days if enabled, then automatically deleted
• Website Analytics: Subject to analytics provider retention settings, if enabled

Your Rights

Because we don't collect personal information, traditional data subject rights (access, correction, deletion) apply minimally. However:

• You can regenerate your device token at any time to disassociate from previous configurations
• You can delete optional query logs at any time
• You can stop using our service at any time by removing the DNS configuration from your device

Children's Privacy

ClearDNS does not knowingly collect any personal information from anyone, including children under 13. Our service is designed to protect families, including children, without requiring or storing any personal data.

Changes to This Policy

We may update this Privacy Policy from time to time. We will post any changes on this page with an updated revision date. We encourage you to review this policy periodically.
