What stays in your browser
The tools calculate in your browser. The amounts, dates and invoices you type are neither sent to us nor stored by us. Closing the page erases them, unless you download a CSV yourself.
If you click to save your choices in a results panel, only the need and check-in frequency you selected are stored locally in this browser. Use the clear control in that same panel to remove them. No amounts, invoice details, documents or calculated figures are saved by this feature. These choices are not sent to a server or an external analytics service.
The contact form
If you use the contact form, your message and the email address you give are sent to our host, which stores them so we can reply. We delete them once the request is handled, and at the latest twelve months later. You can ask us to access, correct or delete them at the address on the legal notice.
Logs and third parties
Our host keeps technical logs (IP address, page requested, time) for security and to run the service. Fonts and animation libraries are served by this site itself: reading a page sends your IP address to no other service.
Cookies
This site sets no advertising or analytics cookies, so there is no consent banner. If we ever add a measurement tool, it will be described here and, where required, will ask for your consent first.
