VATchecker is a client-side tool. The revenue figures, business type, and country you enter are processed entirely in your browser — they are not sent to our servers or stored anywhere except your own device.
The only data sent externally is:
The invoice generator saves your draft invoice to your browser's localStorage so you can return to it later. This data never leaves your device. You can clear it at any time by clicking Reset in the invoice generator, or by clearing your browser's site data.
VATchecker does not use cookies. Your dark mode preference and invoice data are stored in localStorage only.
