Privacy Policy

Last Updated: September 16, 2026

1. Overview: Privacy by Architecture

At ncpdf ("we", "us", or "the ncpdf team"), we believe the strongest way to safeguard your document privacy is to avoid collecting or storing your files in the first place. We designed ncpdf from the ground up around a privacy-by-architecture model:

  • Client-Side Processing (100% in your browser): Core operations—including PDF Compression, Custom KB/MB Resizing, Merging, Splitting, Page Extraction, Deletion, Rearrangement, Rotation, Watermarking, Page Numbering, Digital Signing, Highlighting, Cropping, and PDF-to-JPG conversions—are executed entirely within your web browser using Web Workers and WebAssembly. Your files are processed in your local device RAM and are never transmitted to our servers.
  • Server-Assisted Conversions (Zero Retention): Office format conversions (such as Word to PDF, Excel to PDF, PowerPoint to PDF, and reverse Office conversions) require dedicated conversion engines. These files are sent via encrypted HTTPS, processed in temporary isolated memory, and automatically and permanently deleted immediately after the converted output is returned to your browser.

2. Information We Collect

We do not require user accounts, registration, or logins. We do not collect names, email addresses, or phone numbers to use our tools.

We only collect standard, aggregate, and anonymized technical data through privacy-conscious analytics tools to maintain application stability and understand global traffic patterns:

  • Pages visited and features utilized.
  • Browser type, operating system, and device category.
  • Approximate geographic region (derived from IP address at the country/city level).
  • Technical performance metrics, error rates, and load times.

We never inspect, log, or collect the contents of your documents or metadata within your uploaded files.

3. Server-Assisted File Handling & Retention

For conversion tools requiring server assistance:

  • End-to-End Encryption: All data transmitted between your device and the conversion engine is encrypted using industry-standard TLS/HTTPS.
  • Immediate Automated Deletion: Files are retained only for the transient duration required to execute the conversion. Once the converted stream is delivered to your browser (or if an error occurs), temporary files are wiped from memory.
  • No Human Access & No AI Training: No staff or automated scanning algorithms read or index your documents, and your files are never used to train machine learning models.

4. Cookies & Analytics

We use minimal cookies and local browser storage strictly for functional preferences (such as saving your preferred dark/light theme and language selection) and for anonymous aggregate analytics.

You can disable or block cookies at any time through your browser settings without impacting your ability to use our client-side PDF tools.

5. Your Privacy Rights

Depending on your jurisdiction (such as GDPR or CCPA), you may have rights regarding your personal data. Because we do not store personal accounts or document records, we generally hold no personal data linked to your identity. For any inquiries regarding analytics data, please reach out to us.
