First things first: Your documents are NEVER available on the public internet after you upload them to PlagScan. As a single user, nobody has access to the full-text of your documents as long as you do not explicitly share your plagiarism reports. Here is a list of how your documents can serve as a source for others, based on their respective settings (again, WITHOUT sharing the full-text).

PlagScan uses an encrypted document transfer method (256-bit SSL via HTTPS) for maximum security. If you would like to activate encryption prior to logging in, select Secure Socket Layer (SSL) is the protocol that enables this safe data transfer via the internet. The SSL protocol makes sure that sensitive data, such as credit card information, cannot be read or manipulated. Many browsers such as Microsoft Internet Explorer, Firefox, Opera, Chrome and others support SSL. The use of SSL is indicated by a padlock icon somewhere in your browser. The position of this icon may vary based on which browser you are using.

Your personal data are never sold or passed on to anybody by PlagScan or our business associates. Read more in our data protection guidelines.

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.
