Privacy Policy
Last reviewed: October 2026 • Effective immediately
Zero File Uploads
All conversions, mergers, compressions, and edits happen locally via JavaScript & WebAssembly. We never receive or store your files.
No Surveillance or Profiling
We do not build user behavioral profiles, sell advertising IDs, or monetize personal information. Ever.
End-to-End P2P Encryption
Our peer-to-peer sharing utilizes WebRTC with DTLS and SRTP encryption. File transfers occur device-to-device without intermediary file servers.
Client-Side Storage
Any offline states, cached tools, or user preferences remain inside your browser's local storage and IndexedDB on your hardware.
1. The Core Architecture
Unlike traditional software-as-a-service (SaaS) web tools, ProPdfDocs is architected as a client-side execution environment. When you use tools such as the PDF Merger, Image Converter, Passport Photo Generator, or Code Editors, the application bundle is delivered to your browser, which executes the computation using your local system hardware.
At no point are your source files, intermediate buffers, or finalized outputs transmitted to our web servers.
2. Information We Never Collect
- File Content: We cannot see, inspect, read, copy, or retain any files you process.
- Personal Identifiers: We do not require accounts, usernames, emails, or phone numbers to access the utility tools.
- Financial Information: We do not ask for or store credit cards, bank details, or payment histories.
3. Minimal Operational Diagnostics
To maintain uptime, monitor performance, and diagnose browser compatibility bugs across different platforms, we may collect minimal, non-identifying telemetry:
- Aggregated Metrics: Anonymous counters indicating which tools were opened and general browser user-agent strings to verify feature compatibility.
- Crash Reports: Technical error messages (e.g., WebAssembly memory exhaustion) devoid of any file contents or user data.
4. Peer-to-Peer File Sharing (WebRTC)
When you utilize our peer-to-peer file sharing features:
- Signaling servers (e.g. PeerJS / STUN) are utilized solely to establish an initial handshake between your device and the recipient device.
- Once the connection is negotiated, your data streams directly between peers across an encrypted channel (DTLS/SRTP). File payloads never route through or get saved on our servers.
5. Local Device Storage
Our application may use your browser's localStorage or IndexedDB to persist user preferences (such as light/dark theme preference) or temporarily cache application assets for offline operation. This data is isolated to your local device and can be cleared at any time via your browser settings.

Privacy & Data Security FAQ
Detailed answers regarding file privacy, telemetry, encryption, and local data storage.
Do you ever receive, view, or store the files I process?
No. At no point are your documents, images, or files sent to any remote server. Every tool runs locally in your web browser. We have zero access to your file contents, names, or metadata.
How does ProPdfDocs process files without uploading them?
By using modern Web APIs such as WebAssembly (Wasm) and Web Workers, all computational libraries are downloaded once to your client browser and executed locally using your computer's CPU and RAM.
What happens to my data when I close the browser tab?
Once you close the browser tab or navigate away, the working memory (RAM) allocated to your files is immediately freed and cleared by your browser's garbage collection. Nothing is retained.
What telemetry or analytics information is collected?
We collect minimal, anonymous operational telemetry (e.g., page views, which tool was loaded, and general browser type) to detect broken tools and improve features. We never collect personal identifiers, IP logs, or file information.
Can I opt out of analytics tracking?
Yes. If your browser sends a 'Do Not Track' (DNT) or 'Global Privacy Control' (GPC) signal, or if you use privacy extensions/adblockers, our telemetry respects those preferences automatically.
Does ProPdfDocs use advertising cookies or tracking pixels?
No. We do not use third-party advertising cookies, cross-site trackers, Facebook pixels, or commercial data brokers.
How does peer-to-peer file sharing maintain my privacy?
When sharing files, your device creates a direct peer-to-peer WebRTC connection with the recipient. All payloads are end-to-end encrypted using industry-standard DTLS and SRTP protocols.
Does your WebRTC signaling server inspect or store transferred files?
No. The signaling server is only used for the initial handshake to exchange connection metadata (ICE candidates) so both devices can locate each other. File data never routes through the signaling server.
Is ProPdfDocs compliant with GDPR and CCPA?
Yes. Because we do not collect, process, or store personal files on our servers, ProPdfDocs operates under a zero-knowledge paradigm compliant with GDPR and CCPA requirements.
Is ProPdfDocs safe for HIPAA-regulated healthcare documents?
Yes. Because files never leave your local workstation and no Protected Health Information (PHI) is transmitted across third-party networks, our tools comply with client-side local data governance standards.
Can your servers see passwords on password-protected PDFs?
No. Decryption and password unlocking happen entirely in client-side memory via local WebAssembly routines. Your passwords are never transmitted or logged.
What information is saved in my browser's localStorage or IndexedDB?
We only store UI preferences (such as dark or light theme) and static tool code caches so the application can load fast and work offline. No personal data or files are stored without your explicit action.
How can I delete all data stored locally on my device?
You can clear your browser's cache and cookies at any time through your browser's Settings > Privacy menu, which instantly removes all local caches and preferences.
Do you sell or share user data with third-party brokers?
Never. We do not sell, rent, monetize, or disclose any user information to third parties.
How do you protect against cross-site scripting (XSS) and data leaks?
Our application implements strict Content Security Policies (CSP), sanitizes all user input, runs background threads in isolated Web Workers, and enforces sandboxed execution environments.
Who should I contact if I have a privacy concern or vulnerability report?
You can reach out directly to our security and privacy team at propdfdocs@gmail.com or through our contact page. We investigate all security disclosures promptly.
