Privacy Policy

Almost everything runs locally
Except for the 5 AI tools (smart split / summary / translation / Q&A / to Markdown), every tool runs 100% in your browser — compress, merge, split, rotate, delete pages, watermark, encrypt, crop, to image / Word, OCR, and more. Your files are never uploaded to our servers or any third party, and we have no way to access their contents. You can even disconnect from the internet and keep using these tools to verify this.
AI tools: only extracted text is sent
The AI features — smart split, PDF → Markdown, summary, translation, Q&A, plus PDF → Word's optional AI re-flow — call the DeepSeek language model. Smart split's local manual mode does not call DeepSeek or send document content. Only after you explicitly choose AI mode for the current file do we send page-by-page extracted text, never the original PDF or page images. Text-layer extraction and OCR both run locally, and the text is discarded after the request completes.
Rate-limiting data
To prevent abuse, AI tools have a daily per-visitor limit. We identify visitors using an irreversible hash of your IP address and browser signature — we do not store your raw IP address.
What we don't collect
We don't collect your name, email, phone, or other personally identifying information, and we use no third-party advertising or tracking cookies. We use a single cookie to remember your chosen interface language (中文 / English).
Third-party services
AI features are powered by DeepSeek. When you use an AI tool, the extracted text is sent to DeepSeek for processing, subject to its privacy terms. Once paid subscriptions launch, payments are handled by third-party payment providers; we never touch your card details.
Technical data when you visit the website
When you visit moguanpdf.com, as with any website, our hosting and CDN provider (Vercel) processes some technical data in server logs (such as your IP address, browser/device signature, request time, and the pages you access) to keep the service secure, debug issues, and operate normally. We use Vercel Analytics to count aggregate traffic; it records the page address, referrer, approximate location (country / region / city), and device and browser type. When you export a PDF from Print to Exact Size, it also records the paper preset, PDF page count, and copy count — never the images, filenames, or finished dimensions you enter. It uses no third-party cookies: visitors are counted using a hash derived from the request, and that identifier is discarded after 24 hours, so it cannot identify you personally or follow you across sites. Beyond that we embed no third-party advertising scripts, and set no tracking cookies beyond the single interface-language cookie. This technical data is not used to profile you or to serve ads.
Data controller and your rights (GDPR)
MoguanPDF (moguanpdf.com) is operated by an independent developer, who is the data controller for this site under the GDPR. If you are in a region where the GDPR or similar laws apply, you have the right to access, correct, or delete personal data relating to you, or to object to its processing — though note that classic tools run entirely in your browser, so we never receive your files, and AI tools process only extracted text which is discarded after use. For any privacy request or to exercise your rights, email hello@moguanpdf.com.
