Privacy Policy
1. Overview
At PDF Studio, your privacy is our priority. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data. By using our service, you consent to the practices described in this policy.
2. Browser-First Processing
PDF Studio operates on a browser-first architecture. All PDF processing — including conversion, merging, splitting, editing, and signing — happens entirely within your web browser using WebAssembly and client-side JavaScript. Your files and documents are never uploaded to our servers unless you explicitly use a feature that requires server-side processing.
3. Information We Do Not Collect
We do not collect or store:
- The content of your PDF documents
- Your uploaded files
- Your personal identification information (name, address, phone number)
- Your browsing history outside of our website
4. Information We May Collect
We may collect limited, non-personal information for the purpose of improving our service:
- Usage data: Anonymous statistics about which tools are used most frequently
- Technical data: Browser type, device type, and approximate geographic location (country/region level only) to optimize performance
- Error reports: Anonymous error logs to help us fix bugs
5. Cookies and Local Storage
PDF Studio uses browser local storage and session storage to remember your preferences and tool settings. We may use essential cookies required for the service to function properly. We do not use tracking cookies or third-party advertising cookies.
6. Data Retention
Because processing happens in your browser, your documents and data disappear when you close or leave the page. Any temporary session data used for features like mobile signing is automatically deleted after a short period of inactivity (typically within one hour).
7. Third-Party Services
We do not sell, trade, or otherwise transfer your information to outside parties. We may use trusted third-party services for hosting and analytics, but these providers only receive anonymous, aggregated data and are bound by strict confidentiality obligations.
8. Security
We implement reasonable security measures to protect the limited data we collect. However, since no file data leaves your device, the strongest security is the browser-first architecture itself. You are responsible for keeping your browser and operating system up to date.
9. Your Rights
You have the right to access, correct, or delete any personal information we may hold about you. Since we minimize data collection, in most cases simply clearing your browser storage will remove any stored preferences.
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 effective date. We encourage you to review this policy periodically.
