How Linework handles your PDF

What happens to the document you open

When you choose a PDF, the file is read by JavaScript running in your browser. Mozilla PDF.js parses pages locally. If a page needs scan recognition, a local Tesseract worker performs English OCR in the browser. Extracted rows stay in memory on the open page. Excel generation also runs locally, using a library loaded only when you export. The PDF editor uses the same local model: pages are drawn in the browser and an edited copy is built on your device.

• PDF file contents are read locally by browser-side JavaScript.
• OCR runs locally in the browser.
• Extracted rows remain in browser memory.
• PDF contents are not sent to Linework servers for document processing.
• Reloading or closing the page clears the active working state.
• Exported Excel files and edited PDFs remain on your device.

Linework does not save your documents or extraction history. There is no account and no project store. Download your spreadsheet before you leave; a refresh discards unsaved work.

What still happens when you visit the website

Opening linework.live is an ordinary website visit. Your browser requests HTML, CSS, JavaScript, OCR engine files when needed, and other static assets from the host. Those requests can appear in normal hosting logs. If advertising is enabled, the browser also loads advertising resources from the advertising provider. Browser caching of the app and OCR resources is separate from your PDF and extracted rows.

This page does not claim that Linework collects absolutely nothing. It claims that document contents are not uploaded to Linework for processing. It also does not make claims about DNS lookups, CDN logs, or third-party advertising data practices beyond the fact that those requests can occur.

What Linework does not do

• It does not send your PDF to an external AI service for extraction.
• It does not keep an extraction history after you close the tab.
• It does not require an account to convert a file.
