Privacy Policy
This Privacy Policy explains what information Scientific Calculator Online collects, how it is used, and the choices you have. By using this website, you agree to the practices described below.
This policy covers your use of the Casio Scientific Calculator Online and all related tools on this site.
Information We Collect
This calculator runs entirely in your browser. We do not require an account and we do not collect your name, email address, or calculation history on our servers. Standard technical data such as browser type, device type, and approximate location may be collected automatically for security and analytics purposes.
How We Use Information
Any technical data collected is used only to operate, maintain, and improve this website — for example, to understand which pages are popular, fix bugs, and keep the site secure. We do not sell or rent visitor data to third parties.
Cookies & Local Storage
This site uses browser Local Storage to remember your calculation history, preferred color theme, angle mode (Degrees/Radians), and language selection. These preferences are stored locally on your device and are never transmitted to our servers.
Third-Party Services & Advertising
This website loads fonts from Google Fonts and math libraries from public CDNs. Additionally, we may use third-party advertising partners such as Google AdSense and analytics services like Google Analytics. Third-party vendors, including Google, use cookies (such as the DART cookie) to serve ads based on a user's prior visits to this or other websites. You may opt out of personalized advertising by visiting Google's Ad Settings.
Data Security
We take reasonable measures to protect this website, but no method of transmission over the internet is completely secure. Since calculations happen locally in your browser, your inputs and results are not transmitted to or stored on our servers.
Children's Privacy
This website is a general-audience educational tool and does not knowingly collect personal information from children. If you believe a child has provided personal information, please contact us so we can remove it.
Your Choices
You can clear your browser's local storage or cookies at any time to reset your saved theme, calculation history, and language preferences. Most browsers also let you block cookies entirely, though this may affect some site features.
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for legal reasons. Any changes will be posted on this page with an updated revision date.
