Before uploading

Public-test conditions

Preview only

This is not a medical device or clinical service. It is an experimental visualisation and file-conversion tool.

Anonymised files only

You must remove identifying information before upload. Facial anatomy and other voxel content may itself be identifying.

Best-effort metadata removal

We strip custom, descriptive and nonessential NRRD header metadata before storage. This is not guaranteed to remove every identifier and does not alter identifying voxel data.

No reliance

The service is provided as-is without warranties. You remain responsible for its use; to the extent permitted by law, the operator accepts no responsibility for decisions, losses or harm arising from reliance on an output.

Development review

The operator may inspect uploaded volumes, generated previews and output files to diagnose failures and improve selection quality. A pseudonymous IP-derived identifier and processing records are retained with the test job.
