GDPR

Onbox is GDPR compliant. Our primary infrastructure runs in the EU, we publish a DPA covering all GDPR Art. 28 requirements, and we maintain a public sub-processor list. International transfers to US-based providers are covered by the EU-US Data Privacy Framework (DPF) and Standard Contractual Clauses (SCCs). See our Privacy Policy for full details.
