Cookie Policy

Last updated: June 8, 2026

This Cookie Policy explains how CalculatorGenius ("we", "us", or "our") uses cookies and similar tracking technologies when you visit our website. It explains what these technologies are, why we use them, and your rights to control how we use them.

What Are Cookies?

Cookies are small text files that are placed on your computer or mobile device when you visit a website. They are widely used to make websites work more efficiently, to remember your preferences, and to provide information to the owners of the site.

In addition to cookies, we may use similar technologies such as local storage and pixels to achieve the same purposes described in this policy.

How We Use Cookies

We use cookies for a few different reasons, broadly grouped as follows:

  • Essential / functional cookies — these are necessary for the calculators and core site features to work properly, including remembering inputs you've entered during your current session and interface preferences such as your chosen theme or measurement units.
  • Analytics cookies — these help us understand how visitors interact with CalculatorGenius, which calculators are most popular, and where we can improve performance and usability.
  • Preference cookies — these allow the site to remember choices you make (such as light/dark theme or your default currency) to provide a more personalized experience on return visits.

Third-Party Cookies

In addition to our own cookies, we may use various third-party services that also set cookies on your device when you use CalculatorGenius. These include:

  • Analytics providers (such as Google Analytics or similar tools) that help us measure traffic and usage patterns in aggregate, anonymized form.
  • Advertising partners that may use cookies to display relevant ads and to measure how effective those ads are.

We do not control these third-party cookies, and we encourage you to review the respective privacy and cookie policies of these providers for more information on how they use your data.

Managing Your Cookie Preferences

Most web browsers allow you to control cookies through their settings. You can usually find these settings in the "Options," "Preferences," or "Settings" menu of your browser. From there you can typically:

  • View what cookies are stored on your device and delete them individually.
  • Block third-party cookies, or all cookies, from being set.
  • Set your browser to notify you whenever a cookie is being placed.
  • Clear all cookies whenever you close your browser.

Please note that if you choose to block or delete cookies, some parts of CalculatorGenius — such as saved preferences or calculation history — may not function as intended.

Changes to This Policy

We may update this Cookie Policy from time to time to reflect changes in the technologies we use or for other operational, legal, or regulatory reasons. Any changes will be posted on this page along with an updated "Last updated" date, so we encourage you to review it periodically.
