Castellum

Privacy-First Subject Management for Scientific Research

Features

GDPR Compliance

Researchers disclose the individuals from whom they have gathered data, so that requests for access or erasure can be handled efficiently.

Pseudonym service

Contact details are stored in Castellum so all other databases can work with pseudonyms instead.

Recruitment

Castellum allows you to find potential participants from an existing pool using study specific filters.

Appointments

You can manage appointments for test sessions.

The General Data Protection Regulation (GDPR) mandates that organizations maintain a comprehensive inventory of the data they hold on individuals. This requirement poses challenges within research institutes, where researchers traditionally have a high degree of autonomy in organizing their work.

Castellum addresses this by serving as a centralized repository, enabling researchers to disclose the individuals from whom they have gathered data. Additionally, Castellum allows to track recruitment consent for these individuals, thereby creating a recruitment pool for future research projects.

Castellum makes answering GDPR requests a breeze.

Community

Castellum strives to be an active community project. A public GitLab repository is used to collaborate on the code. Users share insights and suggestions through a chat group and regular community gatherings.
