Privacy
Effective 16 August 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
The current version does not use advertising, account tracking or third-party behavioral analytics. Hosting and security infrastructure may record IP addresses, request times, browser identifiers and error logs to serve requests, prevent abuse and diagnose faults.
Your choices
You can remove local data through browser settings or stop using a feature. For privacy, data or minors-related questions, contact greenplayerstudio@gmail.com.
