Privacy policy

Calcnaut respects your privacy. The calculators run entirely in your browser; the numbers you enter are not sent to or stored on our servers. Your last inputs may be saved locally in your own browser so a calculator remembers them on your next visit, and you can clear them at any time by clearing your browser storage.

We use Google Analytics 4 to understand which calculators are used and how the site performs. Analytics and advertising cookies are off by default and only load if you accept them in the cookie banner, using Google Consent Mode. Until you accept, no analytics or advertising cookies are set. You can change or withdraw your choice at any time with the Cookie settings link in the footer. We do not sell your personal data, and any future advertising would use the same consent. Calculators that link to manufacturers or standards send you to third-party sites with their own privacy policies.

For any privacy question, reach us through the site. This policy may be updated, and the date of the latest build is reflected in the sitemap.
