The documents uploaded to the Validator for checking will neither be saved permanently by the system, nor will the document content or metadata be recorded in the system log.
Due to regulations concerning the protection of information (information classified as confidential or secret) or professional or official secrecy, or data protection regulations concerning particularly sensitive personal data of third parties, the uploading of documents with correspondingly sensitive contents to an external system may be prohibited for you, even if the external system is used solely for purely mechanical processing and no data is stored or logged.
In this case, use a local validation option where the document does not need to be uploaded to an external system.
