Privacy Policy

Last updated: September 1, 2026

At CalcMaster Tools ("we," "our," or "us"), accessible from https://www.example.com/, the privacy of our visitors is of paramount importance. This Privacy Policy document outlines the types of information that is collected and recorded by CalcMaster Tools and how we use it.

1. Information We Do NOT Collect

Our core philosophy is centered on user privacy. CalcMaster Tools does not require user registration, logins, or accounts. All numerical inputs entered into our calculators (such as dates of birth, loan amounts, body weights, or salaries) are processed exclusively inside your local browser via client-side JavaScript. We do not transmit, log, or store your calculator inputs on any server or database.

2. Log Files & Standard Web Analytics

Like standard web hosts and static content delivery networks, CalcMaster Tools utilizes standard server log files. The information inside the log files includes internet protocol (IP) addresses, browser type, Internet Service Provider (ISP), date/time stamp, referring/exit pages, and possibly the number of clicks. These logs are not linked to any personally identifiable information and are used solely for analyzing traffic trends, administering the site, and ensuring server security.

3. Cookies and Web Storage

CalcMaster Tools uses standard cookies and browser local storage (localStorage) strictly to save your preferred UI theme (Light mode or Dark mode). This ensures that your display preferences persist across browser sessions.

4. Advertising Partners & Google AdSense

Third-party ad vendors, including Google, may use cookies to serve advertisements based on a user's prior visits to our website or other websites on the Internet:

• Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to CalcMaster Tools and/or other sites on the Internet.
• Users may opt out of personalized advertising by visiting Google's Ads Settings.
• Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting aboutads.info.

5. CCPA Privacy Rights (Do Not Sell My Personal Information)

Under the California Consumer Privacy Act (CCPA), California consumers have the right to request disclosure of personal data categories collected, request deletion of personal data, and request that a business not sell the consumer's personal data. Because we do not collect or sell personal consumer data, no such sales occur.

6. GDPR Data Protection Rights

We want to ensure you are fully aware of all of your data protection rights under the General Data Protection Regulation (GDPR). Every user is entitled to the rights of access, rectification, erasure, restriction of processing, objection to processing, and data portability. To exercise any of these rights, please contact our administrative desk.

7. Children's Information

Another part of our priority is adding protection for children while using the internet. CalcMaster Tools does not knowingly collect any Personal Identifiable Information from children under the age of 13. If you believe that your child provided this kind of information on our website, please contact us immediately.

8. External Links

Our website may contain links to external sites that are not operated by us. If you click on a third-party link, you will be directed to that third party's site. We strongly advise you to review the Privacy Policy of every site you visit.
