This Privacy Policy explains the collection, use and disclosure of your personal data by The Materials Project in relation to your use of the website materialsproject.org (“Website”). When we use the term “personal data” in this Privacy Policy, we mean information that would allow someone to identify you, such as your name, address, location, employer, email address or other unique identifier.

Collection of personal data

When you register, we will collect information about your affiliation. This helps us to obtain funding and target our tools to the needs of our users.

The Materials Project is being supervised by The Lawrence Berkeley National Laboratory (“LBNL”,or "Berkeley Lab") and adheres to the cybersecurity standards enforced by the National Energy Research Scientific Computing Center (NERSC) for all its systems. Berkeley Lab operates an integrated set of cybersecurity protections designed to efficiently protect research and operational data while enabling cutting edge research. LBNL's systems are Certified and Accredited under NIST 800-53 and have Authority to Operate from the Department of Energy. LBNL's information protection systems include advanced intrusion detection systems, deep forensic logging, vulnerability detection and remediation, and configuration management. In addition, all employees receive annual cyber security awareness training in addition to job-specific training and awareness and ongoing awareness activities conducted by the Laboratory. A continuous monitoring program provides assurance that the systems are providing appropriate protection, and internal and external audits provide ongoing oversight of our operations. LBNL constantly adjusts its protections to changing risks and threats with the goal of optimally protecting scientific work.

Causing damage to federal computer systems is a violation of U.S. law and is subject to criminal prosecution in federal court. In the event of authorized law enforcement investigations, and pursuant to any required legal process, information from Materials Project Web logs may be used to help identify an individual.
