Privacy Policy

Standard Deviation Solver is a free set of statistics calculators built so that using it requires no personal data at all. This policy explains, in plain English, what does and does not happen with your information.

No accounts and no forms

There are no user accounts, no sign ups, and no contact or feedback forms on this site. Because nothing is submitted, nothing you enter is stored by us.

The tools run entirely in your browser

All calculations happen locally on your device using JavaScript. Numbers you type into the calculators are never sent to a server, transmitted over the network by the tool, stored, or logged by Standard Deviation Solver. Closing the tab discards them completely.

Hosting server logs

Like nearly every website, this site is served by a hosting provider whose web server may keep standard access logs. These logs can include technical details such as IP address, browser type, and pages requested, and are maintained by the host for security and operational purposes. We do not use these logs to identify or profile individual visitors.

Cookies and analytics

This site sets no tracking cookies and uses no advertising or behavioral analytics. If basic, privacy respecting analytics are ever added, this policy will be updated before they go live.

Contact

If you email [email protected], your address is used only to reply to your message. It is not added to any list or shared with anyone.

Changes

Any change to this policy will be posted on this page. Continued use of the site after a change means you accept the updated policy.
