Privacy boundaryThe original filename is not stored. Local de-identification occurs before external model processing. Zero source retention removes the upload at extraction and omits content previews and artifacts; derived job status and the structured result remain available for up to one hour so asynchronous retrieval can complete.
Before you upload

Remove content that is not needed for verification. Do not upload passwords, access keys, medical records, or regulated data unless your organisation has an appropriate agreement and configured private deployment.
