隐私政策

Most tools on PDFHome (including Merge PDF) process your files entirely inside your web browser using client-side JavaScript and WebAssembly. Your PDF files are never uploaded to our servers or any third party for these tools — the entire operation, from reading the file to generating the download, happens on your own device.

A small number of advanced tools may require server-side processing to produce a high-fidelity result. When that is the case, it will be clearly stated on that tool's page, and any file temporarily transmitted for processing is automatically and permanently deleted from our servers, typically within one hour of upload.

我们收集两类信息：

• Usage analytics — via Google Analytics and Microsoft Clarity, we collect anonymized usage data (pages visited, tool used, browser type, approximate region) to understand how the site is used and to fix bugs.
• Contact information — only if you email us directly, in which case we retain that correspondence to respond to you.

我们不会将您的个人信息出售给第三方。

PDFHome may display advertisements (including via Google AdSense) to keep the service free. Ad networks may use cookies or similar technologies to serve relevant ads based on your visit to this and other sites. You can opt out of personalized advertising through your ad network's settings.

Depending on your location, you may have the right to access, correct or delete personal data we hold about you, and to object to or restrict certain processing. To exercise any of these rights, contact us using the details on our Contact page.
