Privacy Policy

The short version: what you type into a calculator stays on your device. Here's the full picture.

The short version

[SITE NAME] provides completely free calculators, and every calculation runs directly in your browser. The numbers, names, or text you enter into a calculator are never sent to our servers, never logged, and never stored by us. The site is supported by advertising through Google AdSense, which involves standard analytics and advertising cookies described below - common across free websites.

Information we do not collect

We do not collect, transmit, or store the specific inputs you type into any calculator - loan amounts, health figures, dates, passwords, generated content, or anything else you enter to get a result. That data exists only in your browser for the duration of your visit.

Information collected automatically

Like most websites, we use standard analytics and advertising tools that may automatically collect general technical information when you visit, such as:

  • Pages visited and time spent on the site
  • General device and browser type
  • Approximate location (typically city or region level, based on IP address)
  • Referring website or search engine

This information is aggregated and used to understand overall site usage and improve the site - it is not tied to your calculator inputs.

Cookies and advertising (Google AdSense)

This site runs on Google AdSense advertising, which is how we're able to keep every calculator free. Google and its advertising partners may use cookies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses this data and manage your ad preferences at Google's own Ads Settings and Privacy & Terms pages. Third-party vendors, including Google, may also use cookies to serve ads based on someone's prior visits to this site or other sites on the internet.

You can disable cookies generally through your browser settings, though some site features may not function as intended without them. This site does not currently respond to browser "Do Not Track" signals, as there is no industry-standard way to interpret them consistently.

Third-party services used by specific calculators

A small number of calculators send your input to a third-party service in order to function, described here for full transparency:

  • Currency Converter - fetches exchange rate data from a currency-rate API to display live rates. No personal data is sent, only the currency codes and amount you're converting.
  • QR Code Generator - sends the text you enter to a third-party QR image rendering service in order to generate the QR code image. Avoid entering sensitive personal information if you'd prefer it not pass through that service.

Every other calculator on the site performs all calculations locally in your browser with no data transmitted anywhere.

Contact form

Our Contact page opens your own email application with your message pre-filled - it does not submit data through this site or any third party. We only receive what you choose to send us by email, and we use it solely to respond to your message.

Data retention

Since we don't collect or store your calculator inputs in the first place, there's no personal calculation data retained by us. If you reach out through our Contact page, we retain that correspondence only as long as reasonably needed to respond and for our own records, and you may request we delete it at any time.

Your rights and choices

Depending on where you live, you may have specific rights regarding your personal data:

  • If you're in the EU/UK (GDPR): you have the right to access, correct, delete, or restrict processing of your personal data, and to object to processing based on legitimate interest. Contact us to exercise these rights.
  • If you're a California resident (CCPA/CPRA): you have the right to know what personal information is collected, request deletion, and opt out of the sale or sharing of personal information. We do not sell personal information.
  • Everyone: you can control cookies through your browser settings, opt out of personalized advertising through Google's Ads Settings, or use browser privacy extensions.

Children's privacy

This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can address it. See our Terms of Use for more on age requirements.

Changes to this policy

We may update this policy occasionally to reflect changes in our practices or for legal, operational, or regulatory reasons. The "last updated" date at the top of this page reflects the most recent revision. Continued use of the site after a change means you accept the updated policy.
