Exploring Digital Privacy, Security & Anonymity
Through Technology, Education & Research

Smartphone Trackers

Investigating Privacy Harm

Digital devices collect vast amounts of personal data. We document how this leads to privacy harm and explore tools to resist surveillance, especially in mobile ecosystems plagued by hidden trackers.

Open Source

Experimenting & Educating

We lead workshops, teach privacy and cybersecurity, and develop free and open source software for Yale such as a collaborative document editor and secure password generator. Our remote events host global privacy experts.

Surveillance Map

Mapping Public Surveillance

We organize community walking events where we contribute to crowdsourced maps by documenting cameras, license plate readers, "shot spotters" and other monitoring systems in public spaces.

About Us About Privacy Lab

Privacy Lab is a research and education initiative of the Information Society Project at Yale Law School. Since 2017, we have investigated threats to digital privacy and security through technical analysis, collaboration with journalists, and public engagement. We examine how surveillance systems, from smartphone trackers to urban monitoring infrastructure, impact human rights and democratic participation. Our work includes developing and maintaining free and open source tools, hosting public events, and offering technical expertise to scholars, privacy advocates, and students at Yale and beyond.

Rooted in interdisciplinary collaboration, Privacy Lab serves as a bridge between law, technology, and civil liberties. We train participants in the practical use of privacy-preserving tools and conduct workshops on digital self-defense. From hosting infrastructure such as Tor relays to leading hackathons in New Haven, our events programming is both critical and applied. Privacy Lab's long-term mission is to empower individuals and communities with the knowledge and tools necessary to identify and protect against surveillance. We are guided by a commitment to digital transparency, autonomy, and free expression. Privacy Lab is a member of the Electronic Frontier Alliance, a participant in the Fight For The Future network, and a signatory of the Copenhagen Letter.
