Privacy Policy

Effective / last updated: 2026-06-25

1. Information we collect and do not collect

Math Calculator has no sign-up process and does not request or collect information that directly identifies you, such as your name or contact details. The numeric values you enter into a calculator are used only within your browser, disappear automatically, and are never sent to or stored on the operator's server.

However, the following information may be generated and collected automatically as you use the website.

• Access IP address, browser type and version, operating system, visit date and time
• Pages visited, the previous page (referrer), device information
• Anonymous identifiers via cookies and similar technologies

2. Use of cookies

Math Calculator may use cookies to provide the service and serve ads. A cookie is a small text file that a website stores in your browser to remember visit history and settings.

You can refuse or delete cookies in your web browser settings. Note that blocking cookies may limit some features and ad personalization. Cookie settings can be changed in the settings menu of each browser (Chrome, Safari, Edge, etc.).

3. Google AdSense and third-party advertising

Math Calculator displays ads through Google AdSense. Third-party advertising vendors, including Google, may use cookies to serve personalized ads based on your prior visits.

• Google uses advertising cookies (e.g. the DoubleClick cookie) to serve ads based on your visits to this and other sites.
• You can opt out of personalized advertising in Google Ads Settings.
• You can review and opt out of third-party advertising cookies at www.aboutads.info.
• How Google uses data is described on the How Google uses information from sites that use its services page.

4. Analytics tools

We may use web analytics tools such as Google Analytics to improve the service. These tools use cookies to collect anonymized statistics such as pages visited and time on page, and do not identify any specific individual.

5. Retention and disclosure to third parties

Because Math Calculator does not directly collect or store your personal data, no separate retention period applies. Automatically collected access and cookie information is processed and retained according to the policies of the relevant service providers such as Google. Except as required by law, the operator does not sell or arbitrarily disclose user information to third parties.

6. Your rights

You have the right to refuse data collection through your browser's cookie settings and can disable personalized ads in Google Ads Settings. For inquiries about data handling, please use the contact below.

7. Children's privacy

Math Calculator is not primarily aimed at children under 14 and does not knowingly collect children's personal data.

8. Changes to this policy

This privacy policy may be revised in response to legal or service changes, and any changes will be announced on this page. For significant changes, we will update the effective date.
