Most free tool sites make you sign up before you can download, stamp a watermark on your invoice, or send your text to a server you know nothing about. FreeTools99 does none of that. Each tool is a single, fast page; the maths runs in your browser, and anything you save, such as your invoice details, is kept only in your browser's local storage on your own device.
Each calculator explains its formula, so you can check the numbers yourself. The tax pages state the rules they use and the date they were last checked.
