Calculator information
Values entered into calculator forms are processed locally in your browser to produce the requested result. We do not save those measurements in a database or attach them to a personal profile.
Update-interest forms
The static update-interest forms validate entries in your browser only. This website does not transmit or retain the email address entered in those forms. A separate, secure subscription service must be connected before email updates can be delivered.
Accounts and identity
The website does not offer public registration, login, user profiles, or health-data accounts.
Technical information
Like most hosted websites, infrastructure providers may process limited technical information needed to deliver and secure the service, such as request time, browser type, network address, and security events. Calculator measurements are not included in page URLs or sent by the calculator code.
Cookies and local storage
The calculator experience does not require advertising cookies or persistent storage of your measurements. A short-lived browser preference may record that an update-interest form was completed; the email address itself is not stored.
Third-party sharing
We do not sell calculator inputs or subscriber information and do not expose entered measurements to advertising networks.
Policy changes
If this policy changes materially, the effective date and relevant sections will be updated on this page.
