Privacy Policy & Security Architecture
Document Revision: 2026.4 • Applicable to all pdftoolsai.com utilities
The Zero-Egress Architectural Guarantee
PDF Tools Ai does not store or see your files. We do not have servers that read your documents. All tools run inside your web browser using WebAssembly. Zero bytes of your files or personal data are ever sent over the internet.
1. Technical Proof of Zero Network Egress
You do not have to take our word for it. You can test our network traffic yourself using your browser tools:
- Press F12 (Windows/Linux) or Cmd + Option + I (Mac) to open Developer Tools.
- Click the Network tab. Select Fetch/XHR to watch for data requests.
- Pick any PDF tool and run it (such as compress, merge, or sign).
- Look at the network log. You will see that zero file bytes are sent to any server. Your device does all the work.
2. In-Memory Execution & Ephemeral RAM Lifecycle
When you pick a PDF, your browser loads it into temporary memory.
- ✓No Local Storage Writes: We never save files to your cookies, LocalStorage, or browser cache.
- ✓Quick Memory Cleanup: When you close the tab or switch tools, your browser clears the memory right away.
3. Cryptographic Standards & Password Protection
When you lock a PDF with our Protect PDF tool, it uses strong AES 256-bit encryption.
Your password stays in your device memory. It is never sent to the cloud, never saved, and cannot be seen by our team.
4. Global Regulatory Alignment (GDPR, HIPAA, FERPA, CCPA)
Because we never see or store your files, our site follows strict global privacy rules:
5. Tracking Cookies & Telemetry Policy
PDF Tools Ai is 100% free of ads and tracking. We do not use ad tracking cookies, pixels, or social trackers. Standard web server logs are used only to stop spam attacks and keep the site fast.
