Privacy Policy
What this site collects, what it does not, and how long anything is kept.
Analytics
This site is static. Pages are served as files; there is no user account, no login and no personal data store. If aggregate traffic measurement is in use, it records page views rather than individuals, and is not used to build a profile.
Cookies and local storage
No advertising or cross-site tracking cookies are set. Where the site remembers a preference — a reduced-motion choice, a selected unit — it is stored in your own browser and never transmitted.
Contact messages
If you use the contact form, the message is used to answer your question and is not added to a mailing list, sold, or shared. Do not include personal information you would not want stored in an email inbox.
Third parties
Fonts, stylesheets, scripts and 3D libraries used by this site are served from the same origin. No external content delivery network is used, and no third-party embed receives your browsing data from these pages.
Your rights
Under applicable data protection law you may request access to, correction of, or deletion of anything held about you. Because this site holds no accounts, in most cases there is nothing to retrieve — but a request can be made and will be answered.
Changes
If this policy changes, the revision date below changes with it. Material changes will be described rather than silently applied.
