First, in your browser
Your 3MF or STL is opened and previewed in your browser’s working memory. The local model state disappears when you replace the file, reload or close the page.
Plain-language policy
Your model stays yours.
StudBloom processes only what is needed to preview your model and create the 3MF you request. It does not build a model library, publish uploads or use them to train AI.
No account required Anonymous counts only No model archive
The short version
Only when you export
The derived mesh, stud positions, settings and file name are sent through an encrypted connection to create your requested 3MF. The original 3MF package or STL file is not uploaded separately.
No durable model copy
The StudBloom application processes the export in request memory, returns the result with no-store instructions and does not intentionally write model geometry to a database, object store or application log.
What the host still processes
OpenAI Sites and its infrastructure providers process technical and operational data needed to host and secure the service. Sites currently offers no data-residency guarantee, and provider-controlled security logs may exist. Do not upload confidential, personal or sensitive model content.
Data and purpose
- Model data: used only for previewing and producing the requested 3MF.
- File name and settings: used to label and configure the export.
- Language preference: EN or DE is stored only in your browser.
- Anonymous usage counts: StudBloom stores only the UTC date, one of four fixed event names and the total count. It stores no cookie, user or device identifier, IP address, file name or model data with these counts.
- Technical request data: the hosting platform and short-lived abuse controls may process IP address, timestamps, headers and security events to operate and protect the site. These are not added to the model or aggregate metrics database.
- StudBloom adds no advertising, behavioural analytics or third-party tracking cookies.
Retention and deletion
StudBloom keeps the model only for the active browser session and the duration of an export request. Anonymous daily event totals are kept without automatic deletion because they cannot be assigned to a visitor, device, file or model. Retention of infrastructure security logs is controlled by the hosting provider.
Your rights and responsibilities
Upload only models you created or are allowed to modify and export. Some licences require attribution, permit only private use or prohibit adaptations or commercial use. StudBloom receives only the limited permission needed to process your request and does not claim ownership of your model or result.
Links to other services
MakerWorld and Ko-fi open only when you choose them. Their own privacy terms apply after you leave StudBloom; model files are not sent to them automatically.
Operator and legal notice
StudBloom is a free private project. Privacy and project contact: [email protected]. No telephone support is offered.
