What we keep: nothing of yours

Your invoices are saved in your browser’s own storage on your device. They are never sent to us. Clearing your browser’s data deletes them, so keep a backup file.

Share links carry the invoice inside the part of the link after the # sign. Browsers do not send that part to any server, so the invoice travels only to the person you give the link to.

AI assistants that use Letterwax send the invoice details to letterwax.com/mcp to make the link or the e-invoice XML. We use them for that one reply and store nothing.

Visits may be counted with Plausible, which uses no cookies and stores no personal data. We see how many people opened a page, not who they were.

Fonts are loaded from Google Fonts, which sees your IP address when your browser fetches them.
