Technical request information
Serving the site requires HTTP requests. Hosting providers may process IP addresses, user agents, requested URLs, request times and security or server logs. Do not place sensitive data in a URL; hosting logs may contain requested URLs.
Browser storage and third parties
This release does not use localStorage to save calculator inputs or preferences, and has no analytics or advertising scripts. Formula-source links lead to external sites with their own privacy practices.
Future changes and site operator
If analytics or advertising is introduced, these disclosures and any required consent controls must be updated before activation. Statistics Calculator Lab (“we”, “us”, or “our”) operates this site. Use the contact control below for privacy questions.
Contact email requests
When you activate Show contact email, your browser sends a request to this site to retrieve the contact address. To limit automated requests, the server keeps a keyed hash of your IP address with request counts for a ten-minute rate-limit window. Expired records are removed on a subsequent contact request; it does not store calculator inputs or set a contact-reveal cookie. Normal hosting request logs may also apply.
