Privacy Policy

Browser-Based Processing

All calculator inputs and results are processed entirely in your browser using JavaScript. Your probability values, mean, standard deviation, and other inputs are never sent to our servers. No calculation data is stored, logged, or transmitted.

Shared URLs

The calculator supports sharing results via URL parameters. If you use the share feature, the URL may contain your input values (such as the probability, mean, and standard deviation). Anyone with access to that URL can see those values. Be mindful of this if the values you are working with are sensitive.

Analytics

We may add analytics tools in the future to understand how the site is used (such as which pages are visited and how often). If analytics are added, they will be described in this policy. We will not use analytics to track individual calculation inputs or results.

Cookies

This site does not currently use cookies. If cookies become necessary in the future (for example, to remember user preferences), this policy will be updated to describe their purpose and how to manage them.

Third-Party Services

The site is hosted as a static website. No third-party services currently have access to your calculator inputs. If third-party services are integrated in the future (such as analytics or error monitoring), they will be listed here.

Data Retention

Since calculations are performed in your browser, there is no server-side data to retain or delete. Your browser may cache the website's static files (HTML, CSS, JavaScript) according to standard browser caching behavior, but no personal data or calculation inputs are stored in these files.

Changes to This Policy

This privacy policy may be updated from time to time. The "Last reviewed" date at the top of this page indicates when the policy was most recently checked. We encourage you to review this page periodically for any changes.
