Overview
CalculatorFlows ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our website and free online calculators.
Information We Collect
We do not collect any personal information. Our calculators run entirely in your browser using client-side JavaScript. No calculation data, inputs, or results are ever sent to our servers.
The only data we may automatically collect is standard web server logs for security and performance monitoring, plus aggregate, privacy-focused analytics to understand which calculators people use most. Your actual calculator inputs and results are never sent to us or to any third party.
Local Storage
Some calculators may use your browser's local storage to remember preferences, such as preferred units or theme settings. This data never leaves your device and is not accessible to us.
Analytics & Cookies
We use Google Analytics (via gtag.js) to understand how visitors use the site, which pages are popular, and how to improve the experience. Google Analytics may set cookies and collect information such as the pages you visit, the type of browser and device you use, and an approximate geographic region. This data is processed and reported in aggregate.
Google Analytics does not receive the numbers you enter into our calculators — our calculations run entirely in your browser. To opt out of Google Analytics, install the official Google Analytics Opt-out Browser Add-on, or learn more by reading Google's privacy policy. We encourage users to review their cookie preferences in their browser settings at any time.
Data Retention
Because we collect no personal data and store nothing about your calculations, there is no personal information for us to retain, share, or delete. Server logs are retained only as long as needed for security and operational purposes.
Children's Privacy
Our website is not directed at children under 13, and we do not knowingly collect information from children. If you believe we have collected information from a child, please contact us so we can address it promptly.
Your Rights
Depending on where you live, you may have rights under privacy laws such as the GDPR or CCPA. Because we do not collect personal data, there is no personal data for us to access, correct, or erase. If you have any privacy questions or requests, please reach out and we will respond as soon as possible.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date at the top.
