Data Handling
nutrient_*operations send the file or extracted document content to Nutrient DWS for processing.- Review Nutrient's Processor API security and privacy details before using production or sensitive documents.
- Nutrient documents its hosted Processor API as using HTTPS for data in transit and as not persistently storing input or output files after processing; confirm that matches your organization's requirements before uploading sensitive material.
- Start with non-sensitive sample files and a least-privilege API key.
