Every Project has one Owner and any number of Collaborators. Each Collaborator is assigned a role that precisely controls what they can see and change.
Permission matrix
The number of Collaborators per Project is set by the Owner's subscription. Collaborators do not need a paid plan of their own — they inherit access through the Project.
Roles
The researcher who creates a Project is its Owner. They have full access — including editing, data export, team management, and billing.
Collaborators get one of four roles — Editor, Viewer, Data Analyst, or Participant Manager. Each role is precisely scoped to a task.
The number of collaborators you can invite depends on the Owner's subscription tier. Collaborators don't need their own paid plan.
