Privacy Policy
What this site does and does not collect. The short version: very little, and nothing that identifies you.
What is collected
Nothing that identifies you. This site has no accounts, no login, no newsletter signup that stores an address, and no advertising or tracking scripts. Pages are served as static files.
The interactive tools
The four 3D simulators and the three calculators run entirely in your browser. Every value you type — tank dimensions, water parameters, stocking lists — is held in the page and discarded when you close it. None of it is transmitted anywhere. There is no server-side component to send it to.
Local storage
If the site stores anything on your device it is a display preference such as reduced-motion handling. It is not linked to an identity and it can be cleared by clearing your browser data for this site.
Third parties
There are no third-party scripts, no embedded fonts loaded from external servers, no analytics providers and no content delivery networks. The 3D and animation libraries are served from this site as static files rather than from a CDN, so no third party sees a request from your browser when you use them.
Children
This site is not directed at children and collects no information from anyone, of any age.
Changes
If this policy changes, the change will appear on this page. Because no personal data is collected, there is nothing to migrate and no consent to re-obtain.
