1 · Invoice data never leaves your browser
Files you drop in are parsed by JavaScript running on your device. Nothing is uploaded.
This is not only a promise: the site declares connect-src 'self' in its
Content-Security-Policy, so the browser blocks any outbound request the page might attempt.
Two ways to check it yourself:
- Open the network panel of your browser and process a file — there is no request.
- Disconnect from the network and keep working. The tool continues to function.
2 · What is stored on your device
All of the following lives in your browser's local storage, on your machine, and is never transmitted:
- Your licence key and the email it is bound to, so you do not re-enter it every visit.
- Client profiles: the accounts, tax keys and settings you enter for each client.
- Invoice numbers you have already exported, per client, so duplicates across batches can be flagged. Only the numbers — not amounts, names or files. There is a button that forgets them.
- Your own VAT identifiers, used to tell purchases from sales.
Clearing site data in your browser removes all of it.
3 · What we receive
- Web server logs. The site is hosted on Cloudflare Pages. Serving a page necessarily involves your IP address and user agent reaching the CDN. We do not add any analytics script, and the page makes no third-party requests.
- Email you send us. If you write to support, we have that email and whatever you put in it. The built-in problem report is redacted before you see it: it contains element paths and value shapes, never values.
- Purchase data when you buy a licence: handled by the payment provider (Paddle as merchant of record for EU purchases; Stripe for other channels). We see the email address and the order, not your card details.
4 · No cookies, no tracking
The site sets no cookies and loads no analytics, no fonts, no chat widget and no tag manager. That is deliberate: a third-party script on a page where invoices are opened would have access to that page, and the claim above would no longer be true.
5 · Your rights
Because invoice content never reaches us, there is nothing of yours for us to export or erase beyond support correspondence and purchase records. For those, write to support and we will answer within a reasonable time.
