Privacy Policy

The doc-html-translate browser extension processes PDFs and EPUBs entirely on your device. It does not collect, store, or transmit your documents or any personal data to us or to any third party. It has no servers, no telemetry, no analytics, no ads, and no accounts, and it loads no remote code.

What the extension does

When you open a PDF or EPUB, the extension redirects the page to a local viewer bundled with the extension. The viewer reads the file's bytes in your browser and re-renders its text as HTML so your browser's built-in "Translate page" feature can work on it. All extraction and rendering happen locally, using bundled code (a copy of PDF.js for PDF; a self-contained unzip + HTML pipeline for EPUB). No code is downloaded or executed from a remote server.

Data we collect

None. We have no servers and receive no data from the extension.

Data stored on your device

The extension uses the browser's local extension storage only to remember your settings: whether reflow is enabled (globally and per-site), and your reading preferences (font size, font family, theme). This data never leaves your device and is removed if you uninstall the extension.

Network access

The extension itself makes no network requests to any server we control. It fetches the PDF or EPUB you opened (from the site or local file you chose) in order to render it. Translation is performed by your browser's own built-in translation feature, which you invoke yourself; that feature is governed by your browser vendor's privacy policy, not ours.

Permissions

• declarativeNetRequest and host access - used solely to redirect PDF/EPUB opens to the local viewer and to fetch the opened file for local rendering. No browsing data is read or transmitted.
• storage - used solely to save the settings described above.

Children's privacy

The extension is a document-reading utility and does not knowingly collect any data from anyone, including children.

Changes

If this policy changes, the updated version will be published at the same URL with a new "last updated" date.
