Privacy policy
Effective 13 October 2026. Measurements are processed in your browser. We do not operate an account system, contact submission endpoint, advertising tag or analytics tag.
Share links and hosting
Share links encode calculator settings in the URL fragment after #. Anyone receiving the link can read those measurements. Fragments are not sent as part of HTTP requests; avoid including personal information. The hosting provider may process IP addresses and request metadata to deliver and secure the site under its own policies.
Analytics and advertising
Google Analytics and AdSense are not enabled. No analytics or advertising cookies are set by this application. If these services are introduced, this policy and consent controls must be updated before tags load. No consent is implied by using this tool.
Contact
A verified privacy contact is pending. See the contact availability page. A public commercial launch should establish an operator contact and review applicable privacy obligations.
