Last updated: November 11, 2026.
This policy explains what information Calculator HQ ("the site") collects, how it is used, and the choices you have. The site is a set of free calculators; using them does not require an account.
Information you enter into the calculators
The numbers you type into the calculators — rates, hours, salaries — are processed entirely in your own browser. They are not transmitted to us, not stored on any server, and not saved when you leave the page. There is nothing to delete because nothing is kept. One exception, which contains no calculator numbers: if you change the currency selector, that choice is saved in your browser's local storage so the site remembers it on your next visit. Clearing your browser's site data removes it.
Information collected automatically
Like most websites, the site's hosting provider records standard server log information when you visit, such as your IP address, browser type, the pages you requested, and the date and time. This is used to operate the site, measure overall traffic, and diagnose problems. We do not operate user accounts and do not build profiles of individual visitors.
Cookies
The site itself sets no cookies for the calculators to work. However, cookies may be set by third-party services described below — in particular advertising partners. A cookie is a small text file stored in your browser. You can block or delete cookies in your browser settings at any time; the calculators will continue to work, though advertising may become less relevant.
Third-party advertising
The site is supported by advertising served by third parties, including Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this and other sites on the Internet.
- You can opt out of personalized advertising by visiting Google's Ads Settings.
- You can opt out of many other third-party vendors' use of cookies for personalized advertising at aboutads.info/choices.
- Advertising partners may also collect information such as your IP address and browser details to measure ad performance and prevent fraud, under their own privacy policies.
Email you send us
If you contact us by email, we receive your email address and the contents of your message. We use them only to respond to you, and we do not sell them or add them to a marketing list.
Children's privacy
The site is a general-audience utility and is not directed at children under 13. We do not knowingly collect personal information from children.
Changes to this policy
If this policy changes — for example, if new advertising or analytics services are added — the updated version will be posted on this page with a new "last updated" date.
