Private PDF Saver does not collect, store or send any personal data, and it makes no network requests of any kind.

When you save a page, Firefox turns it into a PDF on your computer and saves it where you choose. The add-on reads the page's title and address only at that moment, to suggest a file name, and keeps neither.

The only thing the add-on stores is its own settings (paper size, orientation, margins, backgrounds, headers and footers, and the file-name pattern), in your browser's local extension storage. They never leave your computer, and Firefox removes them when you remove the add-on.

Questions: write to the support address on the add-on's page.
