This processing is based on Article 6(1)(f) GDPR. The legitimate interest lies in providing this website securely, reliably, and efficiently. There is no full control over GitHub’s processing or data retention periods.

GitHub also processes data in the USA and other countries. According to GitHub, relevant transfers rely in particular on the European Commission’s Standard Contractual Clauses, and GitHub participates in the EU-US Data Privacy Framework.

Further information is available in the GitHub General Privacy Statement.

The information will be deleted once the inquiry has been fully resolved, provided that no statutory retention obligations or other legal grounds prevent its deletion.
