2. Personal Data We Collect

We collect the following categories of personal data:

Research and Platform Content

Research projects, protocols, ethics submissions, datasets, documents, analyses, and other content you create or upload through the Service. This may include personal data of research participants where you include such data in your datasets — you are the data controller for participant data, and we act as your data processor.

Emails, support requests, and feedback you send to us, including any personal data contained therein.

We do not intentionally collect special categories of personal data (Article 9 GDPR) such as health data, biometric data, racial or ethnic origin, or political opinions unless they form part of research data you explicitly upload for scientific research purposes, in which case the lawful basis is Article 9(2)(j) GDPR (scientific research).
