Privacy
Last updated 19 October 2026. This notice applies to the current public beta on mindhall.art.
Local project data
Mindhall currently requires no account. Text, images, audio, scene settings and voxel progress are stored in this browser by default and are not automatically synchronized to our servers. Clearing browser data may permanently remove projects; export `.hall.json` backups yourself.
Exports and sharing
Project files and offline web packages are generated in your browser. You decide where they are stored and who receives them. An export may include the images, text and audio you added, so check content and permissions before sharing.
Third-party AI features
When you deliberately use an experimental feature such as image-to-3D, the selected image and prompt may be sent to the third-party model service identified in the interface. Do not submit sensitive personal information, confidential material or content you have no right to process. The provider applies its own terms.
Analytics and cookies
This site uses Google Analytics 4 to measure page visits, device types, traffic sources and interactions such as opening contact options. Cookies may distinguish sessions. Google Signals and advertising personalization are disabled. We do not send form entries, conversations, local files or project data to analytics; page URLs sent by our code omit query strings and fragments. Google processes analytics under its privacy policy. Hosting and security infrastructure may also retain request and error logs.
Your choices
You can clear cookies and local data in your browser, use its tracking-blocking controls, or stop using a feature. For privacy, data or minors-related questions, contact greenplayerstudio@gmail.com.
