At PrfvNote, your privacy is our highest priority. This policy explains how we protect your information and maintain our commitment to zero-knowledge, secure communication. We believe in complete transparency about our privacy practices.
Last Updated 2026-04-04
Data Collection
We operate on a zero-knowledge principle, meaning we collect minimal data necessary for service operation. We do not require registration, store personal information, or track user behavior. The only data we temporarily process is encrypted message content, which is immediately deleted upon reading. We may collect anonymous usage statistics and technical logs for security and performance purposes, but these cannot be linked to individual users or specific messages.
Use of Data
Any data we collect is used solely for providing and improving our secure messaging service. We never sell, rent, or share user data with third parties for marketing or commercial purposes. Technical logs may be used for security monitoring, preventing abuse, and maintaining service reliability. We do not analyze message content, create user profiles, or use data for advertising purposes. Our zero-knowledge architecture ensures we cannot access or use your message content even if we wanted to.
Data Storage
Messages are encrypted on your device before transmission and stored temporarily on our secure servers until they are read and automatically deleted. We use industry-standard security measures including AES-256 encryption, secure data centers, and regular security audits. No message content is stored permanently, and encryption keys are destroyed immediately after message deletion. Our servers are located in secure facilities with physical and digital protection measures meeting the highest industry standards.
User Rights
You have complete control over your messages and privacy. Since we operate on a zero-knowledge basis, we cannot access your message content to modify or delete it - only you and your intended recipient have this capability. You have the right to know what limited data we collect, how it's used, and how we protect it. You can contact us with any privacy concerns or questions about our practices. We are committed to transparency and will promptly address any privacy-related inquiries.
Third-Party Services
We use minimal third-party services, and any we do use are carefully selected for their privacy and security standards. These may include cloud infrastructure providers, security monitoring tools, and analytics services that provide only anonymous usage data. We ensure all third-party services meet our strict privacy requirements and cannot access your message content. We regularly review and audit all third-party relationships to maintain our privacy commitments.
Data Security
We implement multiple layers of security to protect your information, including end-to-end encryption, secure transmission protocols, regular security audits, and continuous monitoring for threats. Our infrastructure is designed with security-first principles, and our team includes cybersecurity experts who continuously update our protection measures. We use industry-leading practices for data protection, including encrypted storage, secure key management, and comprehensive access controls.
Children's Privacy
Our service is designed for general use and we do not knowingly collect personal information from children under 13. Since we don't require registration or collect personal data, we cannot determine user ages. Parents and guardians should supervise children's internet use and ensure they understand the importance of not sharing personal information online. If you believe a child has used our service inappropriately, please contact us immediately.
Policy Updates
We may update this privacy policy to reflect changes in our practices, technology, or legal requirements. Any significant changes will be prominently displayed on our website and will not reduce your privacy protections without your consent. We encourage you to review this policy periodically to stay informed about how we protect your privacy. The date of the last update is always displayed at the top of this policy.
