Privacy Policy

Last updated: March 25, 2026

MapleKit is committed to protecting your privacy. This policy explains what data we do and do not collect, how our calculators work, and how any optional services (such as analytics or advertising) may use data. We encourage you to read it in full.

What We Do Not Collect

We do not collect, store, or transmit the data you enter into our calculators. When you type your height, weight, loan amount, or any other value into a MapleKit calculator, that information is processed entirely in your browser. It is never sent to our servers or stored in our databases. We do not require you to create an account, log in, or provide your name, email address, or payment information to use our calculators. We do not use your calculation inputs for advertising, analytics, or any other purpose.

How Our Calculators Work

Our calculators run on your device using JavaScript. The formulas and logic are executed in your browser. No calculation data is transmitted over the internet to MapleKit. This design is intentional: we believe that sensitive information such as health metrics or financial figures should stay under your control. You can verify this by using your browser’s developer tools or network monitor—you will not see your inputs being sent to our servers.

Third-Party Services

We may use the following third-party services that have their own data practices:

• Google Analytics: If enabled, this service may collect anonymous usage data such as page views, approximate location (country-level), device type, and referral source. This helps us understand how the site is used so we can improve it. Analytics data is not tied to your calculator inputs.
• Google AdSense: We may display advertisements provided by Google. AdSense may use cookies and similar technologies to show relevant ads and measure ad performance. Google’s advertising policies and how you can control ad personalization are described in Google’s privacy and ad settings.

These services may collect information according to their own privacy policies. We do not control their data collection. You can limit or block cookies and similar technologies through your browser settings, though this may affect site functionality or ad relevance.

Cookies

We may use cookies or similar technologies for analytics and advertising purposes (as described above). We do not use cookies to track or store your calculator inputs. You can disable or delete cookies in your browser settings. Note that blocking cookies may affect how our site or third-party services function.

Data Retention

Because we do not collect or store your calculation data, there is nothing for us to retain or delete in that regard. Any data collected by third-party services (such as analytics or ad networks) is subject to their retention policies. We do not maintain databases of user inputs or personally identifiable information from calculator use.

Your Rights

Depending on where you live, you may have rights regarding personal data (for example, access, correction, deletion, or portability). Because we do not collect personal data through our calculators, there is typically no such data held by us to access or delete. If you contact us (for example, via email), we will handle your message in line with this policy and will not use your contact details for marketing unless you have agreed. For data held by third-party services, you may need to contact those providers or use their privacy tools (e.g. Google’s privacy controls).
