Every calculator on PawSafe is deterministic: the same inputs always produce the same output, and the formula is documented in plain language on the tool page. Where a figure depends on an external benchmark — a published rate, a statutory limit, or an industry cost range — the page cites the publisher and links to it.
We separate inputs you control (balances, rates, dimensions, weights) from assumptions we supply (default rates, waste factors, contingency percentages). Assumption defaults are deliberately conservative and every one of them is editable on the tool page, so you can substitute your own quote or local figure.
Nothing you type is transmitted. The calculations execute in JavaScript in your browser, which means the tools work offline and no personal data is collected.
