Privacy Policy

This policy is provided in English. Translations are for convenience; the English version prevails.
Summary
This tool runs entirely in your browser. We do not collect, store or transmit your personal data, and the models you generate never leave your device.
What we collect
No personal data. There is no account system, no server that receives your input, no advertising and no tracking of individuals. We do collect aggregate, anonymous visit statistics — page views, referrer, country and browser type — through Cloudflare Web Analytics, which uses no cookies and no fingerprinting. Every feature is available without registering or providing any information.
Data stored on your device
For two functional settings we use your browser's local storage — not cookies:
lang— the interface language you selectedtut_done_v1— whether you have already seen the tutorial
Both stay on your device. They are never sent to us or to anyone else, and you can remove them at any time by clearing your browser's site data. If you block local storage the tool still works — it simply will not remember your language choice.
Your models
All geometry is calculated locally in your browser and the STL file is assembled on your device before download. Your model data is never uploaded to any server.
Third-party services
When the page loads, your browser fetches the 3D engine (Three.js) from a public content delivery network — jsDelivr, with unpkg as a fallback. It also loads Cloudflare Web Analytics, which counts visits without cookies and without identifying you. As with any web request, those providers can see your IP address, user agent and the requested URL. We neither control nor have access to that data; please refer to their respective privacy policies for details.
Cookies
We do not use cookies, and we do not use third-party cookies, pixels or fingerprinting. The visit statistics described above are cookieless: nothing is stored on your device and you are not tracked across sites.
Children's privacy
This tool is not directed at children, and we do not knowingly collect information from anyone — including children under 13, or the equivalent age in your jurisdiction.
Your rights
Because we do not collect or process personal data, there is no personal data for us to access, correct, export or delete, and we do not sell personal information. Under the GDPR, the CCPA and comparable laws, the practical position is simply that we hold nothing about you. If you have any question, please contact us using the address below.
Changes to this policy
If the way data is handled changes — for example if we add advertising — we will update this page and change the date above before the change goes live.
