Chính sách Bảo mật

1. Cam kết Bảo mật

ZentoPDF ("we", "us", "our") is fundamentally a privacy-focused service. This Privacy Policy outlines our unwavering commitment to protecting your privacy. Our core principle is simple: your files are your files. We do not and cannot view, access, store, or share your documents. All PDF processing occurs entirely on your own computer, within your web browser (client-side).

1.1 Nguyên tắc Xử lý Phía máy khách

Unlike other online PDF services, ZentoPDF does not upload your files to a server for processing. The tools you use are powered by JavaScript and WebAssembly libraries that run directly on your device. This means your data never leaves your computer, providing you with the highest level of privacy and security.

2. Thông tin Chúng tôi Không Thu thập

Because of our client-side architecture, we are technically incapable of collecting the following information:

• The content of your PDF files or any other documents you use with our tools.
• Any personal data contained within your documents.
• Filenames of your documents.
• Any derived information or metadata from your files, beyond what is necessary for the tool to function during your active session (and this is immediately discarded).

3. Thông tin Chúng tôi Có thể Thu thập

To improve our website and services, we may collect anonymous, non-personally identifiable information. This type of data helps us understand how users interact with our site, which tools are most popular, and how we can improve the user experience. This includes:

• Usage Analytics: Anonymized data such as which tools are used, how often they are used, and which features are accessed. This is aggregated and cannot be tied back to an individual user or document.
• Performance Data: Anonymized error reports or performance metrics to help us identify and fix bugs. This data contains no personal information or file content.

We use privacy-respecting analytics platforms for this purpose. Specifically, we use Google Analytics to track anonymous visit counts. This means we can see how many users visit our site, but we never collect personal information or identify individual users.
