Yes. If you would like to check documents that require an NDA, need to be kept confidential or you want to keep secret for another reason, we provide organizations with the option to mark documents as private (via the padlock button in your document manager). Private documents can be checked but will not be checked against. The document can not be put into the organization’s repository and will not be part of the PlagScan Plagiarism Prevention Pool. After you checked your document you can delete it. It will be gone forever and not remain on our servers.
Documents of single users are likewise private by default, with the difference that they always can be checked against within this one account.
