PDFHub.AI processes all PDF files locally in your browser. Your files are never uploaded to our servers. We do not store, analyze, or share any of your documents.
All PDF operations (merge, split, compress, convert) and AI features happen directly on your device or through secure API calls. Your files never leave your computer.
For AI features (chat, summary), only extracted text is sent to our AI service provider (智谱AI). We do not store your documents or chat history.
When you create an account, we store your email address and encrypted password. This data is used solely for authentication and Pro status verification.
We use essential cookies for login functionality. Third-party services (Gumroad, Google AdSense) may set their own cookies for payment processing and advertising.
