Privacy Policy

Last Updated: September 3, 2026

Calculator Library Portal ("we", "our", "us") respects the privacy of visitors and users of this website. This Privacy Policy explains the general types of information that may be collected, how information may be used, and the choices available to visitors.

1. Information We Collect

Calculator Library Portal is primarily a static website. We do not require visitors to create an account merely to use the calculator library. Depending on how the website and third-party services are configured, ordinary technical information such as IP address, browser type, device type, operating system, referring page, approximate location and access time may be processed by hosting, security, analytics or advertising services.

2. Calculator Inputs

Some calculators require users to enter values such as amounts, dates, units, quantities, rates or other calculation inputs. Whenever a calculator performs calculations locally in the browser, those values may remain within the browser and may not be transmitted to our server.

Users should nevertheless avoid entering passwords, payment-card numbers, government identification numbers, confidential business information or other unnecessary sensitive information into any public website calculator.

3. Cookies

The website or third-party services may use cookies or similar technologies. Cookies may be used for functionality, preferences, analytics, security or advertising. More information is available in our Cookies Policy.

4. Advertising

We may display advertisements through third-party advertising providers, including Google AdSense. Advertising providers may use cookies or similar technologies to provide, measure or personalize advertising according to their own policies and applicable settings.

5. Analytics

We may use analytics technologies to understand general website usage, including which pages are visited, approximate traffic levels, device information and performance information. Analytics information is generally used to improve the website rather than to identify individual visitors personally.

6. External Links

Calculator Library Portal contains links to StartKnowledge and other related projects and external websites. When you leave our website, the privacy practices of the destination website apply. We recommend reviewing the privacy policy of any third-party website you visit.

7. Third-Party Services

Third-party providers may independently process information when their services are loaded or used. Examples can include advertising, analytics, hosting, content delivery, security and other technical services.

8. How Information May Be Used

To operate and maintain the website.
To provide calculator functionality.
To improve website performance and usability.
To detect abuse, security threats or technical problems.
To understand general website traffic.
To display and measure advertising where applicable.
To respond to user enquiries.

9. Email Communications

If you contact us by email, we may receive the information included in your message, such as your email address, subject and message content. We use this information to respond to your enquiry and address the issue described.

10. Data Security

We take reasonable measures appropriate to the nature of the website to protect information under our control. However, no internet transmission or online service can be guaranteed to be completely secure.

11. Children's Privacy

The website is intended for general audiences. We do not knowingly request personal information from children for account creation or other unnecessary purposes. Parents or guardians who believe that a child has provided personal information may contact us.

12. Data Retention

Information may be retained only for as long as reasonably necessary for the purpose for which it was collected, for security, legal, technical or operational reasons, or as required by applicable law.

13. Your Choices

Users may control certain cookies, advertising preferences and browser permissions through their browser or relevant third-party settings. Disabling certain technologies may affect some website functionality.
