Features
GDPR Compliance
Researchers share details about the individuals they’ve collected data from, making it easy to handle requests for access or erasure.
Pseudonym service
Contact details are stored in Castellum so research data can be stored with pseudonyms instead.
Recruitment
Find potential participants from an existing pool using study specific filters.
Appointments
Manage appointments for test sessions or let participants pick themselves.
The General Data Protection Regulation (GDPR) requires organizations to keep a detailed inventory of the data they collect from individuals. This can be tricky for research institutes, where researchers often organize their work with a high degree of autonomy.
Castellum addresses this by acting as a centralized repository where researchers share information about the individuals from whom they’ve collected data. It also tracks recruitment consent, helping you to build a valuable pool of participants for future research projects.
Castellum makes answering GDPR requests a breeze.
Community
Castellum is a small but growing community. We use a public GitLab repository to collaborate on code and a chat group to share insights and suggestions. We also do regular community meetings:
