Data localisation

Data localisation is a legal requirement that certain data be stored or processed within the borders of a specific country or region.

What it means in practice

Localisation turns a location preference into a rule. Where residency is a choice, localisation is an obligation set by statute, regulator or licence condition. Rules take different forms: a primary copy must be local; a copy or mirror must be kept locally even if the main store is abroad; processing must take place locally; or transfers are allowed only through approved mechanisms.

For a customer data platform (CDP), localisation drives deployment: in-country hosting, local key custody, and attention to backups, logs, support access and AI inference.

Example (iGaming): an operator licensed in Brazil keeps betting systems and player data in Brazilian data centres, so a foreign analytics copy is not an option unless the narrow exception applies.
