Terms of Service

CalcLake provides free, browser-based calculators, converters, and generators. There's no account required and no fee to use any tool. We may add, change, or remove tools at any time without notice.

Every tool on this site produces an estimate based on the inputs you provide and a documented formula or methodology, explained on that tool's page. Nothing on this site is financial, medical, legal, tax, or other professional advice, and results should not be relied on as a substitute for advice from a qualified professional. Financial calculators (loans, mortgages, investments, retirement) and health calculators (BMI, calorie, body composition) in particular are estimates only — actual outcomes depend on factors no calculator can account for.

We work to keep every calculation accurate, but the site and its tools are provided “as is” and “as available,” without warranties of any kind, express or implied — including accuracy, reliability, or fitness for a particular purpose. We don't guarantee the site will be uninterrupted, error-free, or available at all times.

To the fullest extent permitted by law, CalcLake and its operator aren't liable for any loss or damage arising from your use of, or inability to use, the site or any tool's results — including decisions made based on a calculator's output.

Don't use the site to violate any law, attempt to disrupt or gain unauthorized access to it (including scraping at a rate that degrades service for others), or misrepresent tool output as an official or certified result.

The site is supported by advertising, and some pages link to external sources or reference third-party services. We aren't responsible for the content, accuracy, or practices of sites we don't operate. See our Privacy Policy for how ads and analytics work here.

The site's design, code, and original written content belong to CalcLake. You're welcome to use the tools and share links to them; please don't copy the site's design or content wholesale for your own use.

We may update these terms as the site evolves. Continued use of the site after a change means you accept the updated terms — material changes will update the “Last updated” date above.
