Privacy Policy

This describes how the Center for Digital Antiquity (Digital Antiquity) and tDAR treat personally identifiable informationDigital Antiquity values the privacy of our users.

A.  Information We Collect

Digital Antiquity collects information to provide better service to all of our users. Information is collected actively as users register, browse, or interact with tDAR and as users interact more directly with Digital Antiquity staff.

The information we collect includes:

  1. Contact Information: We use contact information to notify users of requests within the system (such contact or download requests for confidential files), to assist in the troubleshooting, or other issues. Contact information is not shared with third parties unless that information is required to provide a service such as processing credit card information or sending email.
  2. Device information: For example, what web browser you use or if you are using a mobile device.
  3. Log Information: What a user does on tDAR is captured in server logs including the IP address of your computer. Our log data tracks searches, downloads, pages viewed, and information that may be useful for debugging purposes when users save resources or perform other actions within the system.  This information helps us understand how users interact with tDAR and assists us in troubleshooting issues within the system. Log data is stored for two weeks and then deleted automatically.
  4. Usage Information: We track searches, downloads, page views, and other usage information independent of personal information.
  5. Cookies and Other Identifiers: tDAR uses cookies to assist with authentication and storage of user preferences.
  6. Use of third Party Software and Servicies: Digital Antiquity uses third party software to provide some services such as web analytics (e.g., analytics performed by Google), hosting of fonts or other files, or credit card processing.

B.  How We Use Information that We Collect

We use the information we collect to provide, maintain, protect, and improve tDAR and assist in developing new features and services.

C.  Management and Discloser of Personal Information

Digital Antiquity provides users with the means to manage their own personally identifiable information from the tDAR user profile. Users  control what information Digital Antiquity maintains in their profile, such as phone numbers or contact information.  Digital Antiquity will not sell users’ contact information and will not disclose it to third parties unless legally obligated to do so.

D.  Requesting a copy of your User Information

Upon request, we can provide a user with a copy of the user’s information maintained in their user profile.  Requests for information within specific files in tDAR, such as PDF documents, should be directed to the authors or contributors of those materials

E.  Opting Out and the Right to be Forgotten

If you wish to have your personally identifiable information removed from tDAR, please contact us at: privacy@tdar.org.  Requests for the removal of personally identifiable information within specific files in tDAR, such as PDF documents, should be directed to the authors or contributors of those materials.

F.   Backups of Data

Backups are a critical aspect of maintaining the tDAR repository. Backups are maintained for at least one year. Data on backups are encrypted prior to being stored offsite.  Opting out and removing data from tDAR will remove data from all subsequent backups. It is not currently feasible to purge data from all historical backups. If we restore files prior to an opt-out request, we will filter out data flagged data when restoring the database.


From time to time the Board of Directors of the Center for Digital Antiquity at its discretion will add to or modify its Policies and Procedures.
