GDPR & Data Residency

ID5 is owned and operated within the EU. Data processed by an EU/EEA-owned vendor often stays within the European Economic Area, which can simplify GDPR transfer documentation. This is a technical signal only — verify actual data-processing locations in the vendor's DPA and Privacy Policy, since some EU-owned vendors still use sub-processors outside the EEA.
