Is it really free? Yes. No subscription, no recurring charge, no signup, no watermark. Free forever.
Do I need an account? No. The tool works without any signup.

the how-to guide for more detail.
Where is my invoice data processed? Entirely on your device. The letter is built in your browser from the form fields you enter — invoice numbers, customer details, and amounts are never transmitted to any server. The only network request the app makes is the initial download of the tool itself, and the service worker then caches it for offline use.

Security & Data Privacy
The tool runs entirely in your browser. Invoice numbers, customer details, and amounts are processed locally on your device — nothing is uploaded to a server, and no account or tracking is involved. After the first load, the service worker caches the app so it also works offline, without sending your data anywhere.
