Privacy Policy

Effective / last updated: 2026-06-25

1. Information we collect and do not collect

Crypto Calc has no sign-up process and does not request or collect information that directly identifies you, such as your name, contact details, or wallet address. The values you enter into the calculators (buy price, sell price, quantity, and so on) are used only within your browser, disappear automatically, and are never sent to or stored on our server.

However, the following information may be automatically generated and collected while you use the website:

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

2. Use of cookies

Crypto Calc 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 visits 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, and so on).

3. Google AdSense and third-party advertising

Crypto Calc serves 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 (such as 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 vendor cookies at www.aboutads.info.
• You can learn how Google handles data at How Google uses information from sites that use its services.

4. Analytics tools

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

5. Data retention and third-party sharing

Crypto Calc does not directly collect or store your personal information, so 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, we do not sell or arbitrarily share user information with third parties.

6. Your rights

You have the right to refuse data collection through your browser cookie settings, and you can disable personalized ads in Google Ads Settings. For questions about how data is handled, contact us using the details below.

7. Children's privacy

Crypto Calc is not primarily directed at children under 14 and does not knowingly collect children's personal information.

8. Changes to this policy

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