Privacy Policy
Last updated: July 2, 2026
1. Who We Are
VaultPDF ("we," "us," or "our") operates the website vaultpdf.online. We provide professional PDF tools that process documents entirely within your web browser using client-side JavaScript and WebAssembly technology.
2. Zero-Knowledge Architecture
VaultPDF is fundamentally different from other PDF tools. Our tools run entirely in your browser. When you use any VaultPDF tool:
- Your files are loaded into your browser's local memory only.
- All processing happens on your device using JavaScript.
- Zero bytes of your document data are ever transmitted to our servers.
- We have no technical ability to access, read, or store your files.
- When you close the browser tab, your data is permanently gone from memory.
This architecture means that even if our servers were compromised, your document data would not be at risk — because it was never there.
3. Information We Do Collect
While we never access your documents, we do collect limited technical information to operate and improve our website:
3.1 Analytics Data
We use Google Analytics 4 to understand how visitors use our website. This collects:
- Pages visited and time spent on each page
- Browser type and operating system
- Screen resolution and device type
- Approximate geographic location (country/city level, not precise)
- Referral source (how you found our website)
Google Analytics uses cookies to distinguish unique visitors. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
3.2 Advertising
We display advertisements through Google AdSense and potentially other advertising networks. These services may use cookies and similar technologies to serve ads based on your prior visits to our website or other websites. You can opt out of personalized advertising by visiting Google Ads Settings.
3.3 Server Logs
Our hosting provider (Hostinger) automatically collects standard server logs including IP addresses, browser type, and pages requested. These logs are used solely for security monitoring and are retained for a limited period as determined by our hosting provider.
4. Cookies
We use the following types of cookies:
- Essential cookies: Required for basic website functionality.
- Analytics cookies: Google Analytics cookies to understand website usage patterns.
- Advertising cookies: Used by our advertising partners to serve relevant advertisements.
You can control cookies through your browser settings. Blocking cookies may affect your experience on our website.
5. How We Use Information
The limited information we collect is used to:
- Operate and maintain the website
- Understand usage patterns to improve our tools
- Display advertisements to support free access to our tools
- Ensure security and prevent abuse
6. Data Sharing
We do not sell your personal information. We share data only with:
- Google Analytics: For website analytics (anonymized usage data).
- Google AdSense: For advertisement serving.
- Hosting provider: Server logs as required for hosting services.
7. GDPR Compliance
For users in the European Economic Area (EEA), you have the right to:
- Access the personal data we hold about you
- Request correction of inaccurate data
- Request deletion of your data
- Object to processing of your data
- Request data portability
- Withdraw consent at any time
To exercise any of these rights, contact us at contact@vaultpdf.online.
8. Data Security
Our Zero-Knowledge architecture is the strongest form of data protection: your sensitive documents never reach our infrastructure. For the limited data we do collect (analytics, logs), we rely on the security measures provided by Google and our hosting provider.
9. Children's Privacy
VaultPDF is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
