Tenorshare PDNob Trust Center -
Your Data Security, Our Top Priority

At Tenorshare, we understand that your PDF files often contain sensitive information. That’s why PDNob PDF Editor is designed with industry-leading encryption, privacy compliance, and secure infrastructure to protect your data at every stage — from upload to editing and sharing.

1. Data Security and Encryption

We use advanced security technologies to keep your files safe from unauthorized access and data leaks.

  • AES-256 Bit Encryption – user documents can be encrypted locally by AES-256. Sensitive user data (e.g., login and registration information) is encrypted in storage and during transfer using AES-256.
  • TLS 1.2/1.3 Secure Transmission – ensures end-to-end encrypted connections.
  • Defense-in-Depth Strategy – multi-layer protection across our systems and servers.

2. Global Privacy Compliance

Tenorshare complies with major global data protection standards to ensure transparency and accountability.

Our solutions align with:

  • GDPR (EU General Data Protection Regulation) – gives users in the EU full control over their personal data, including the right to access, correct, or delete it.
  • CCPA (California Consumer Privacy Act) – provides California residents with visibility and control over how their data is collected, used, and shared.

We respect your right to control your personal data — including access, correction, and deletion. Tenorshare never sells or trades user information for commercial gain.

3. Certified and Audited Infrastructure

Our systems are hosted in secure data centers with strict physical and digital safeguards. We regularly perform internal and third-party security assessments to ensure system resilience.

  • SOC 2 (in progress) Compliance – aligns our practices with international standards for data handling and security.
  • Continuous Vulnerability Scanning & Patching – identifies and fixes security issues before they impact users.
  • 24/7 Intrusion Detection and Monitoring – proactively monitors systems to detect and block suspicious activity.

We have obtained the following recognized certifications to ensure high-quality processes and data security:

  • Payment Card Industry Data Security Standard (PCI DSS) – protects sensitive payment and transaction data.
  • CMMI Level 3 Assessment – ensures consistent, high-quality process management.
  • ISO 9001 Quality Management System – demonstrates our commitment to reliable product development and customer satisfaction.
  • ISO 56005 Innovation Management – supports structured and secure innovation practices within our organization.

4. Backup and Business Continuity

Your data remains safe even in unexpected situations. We maintain real-time backups, redundant systems, and disaster recovery plans to minimize service disruption and data loss.

  • Redundant Infrastructure – ensures system reliability even if one server fails.
  • Secure Data Backups – keeps copies of essential data protected in case of unexpected errors.
  • Business Continuity Planning – ensures services can be quickly restored after incidents.

5. Access Control and Authentication

Only authorized users can access sensitive information. We enforce strict access management policies to prevent insider or external misuse.

  • Session Timeout and Secure Login – automatically logs out inactive sessions to prevent unauthorized access.

Tenorshare maintains a responsible vulnerability disclosure program. We encourage security researchers to report potential risks to us directly and respond swiftly to every valid report.

  • Public Security Bulletins – share important updates about security improvements.
  • Prompt Security Patching – addresses vulnerabilities quickly to maintain system integrity.
  • Responsible Disclosure Policy – fosters open communication with the security community to enhance protection.
