What is Data residency?
Data residency is the guarantee that a defined set of data is stored and processed in a named country or region. For AI systems it must cover four things: the source documents, the vector index, the prompt and answer logs, and the model inference itself.
Also known as: AI data residency, where is my AI data stored.
Most AI vendors answer residency questions with storage only. That leaves the largest exposure untouched, because prompts and retrieved passages are sent to whichever model endpoint the vendor uses, often in another jurisdiction, and are frequently retained for abuse monitoring.
A credible residency statement names the data centre region for each of the four layers, states the retention period for logs, and lists every subprocessor that can technically read content.
How Uthereal handles it
With Uthereal, storage, index, logs and inference all sit in the same chosen region - Switzerland by default, or your own infrastructure.
Auf Deutsch: Datenresidenz
Datenresidenz bedeutet, dass Daten in einem festgelegten Land gespeichert und verarbeitet werden. Bei KI-Systemen muss das vier Ebenen umfassen: Quelldokumente, Vektorindex, Prompt- und Antwortprotokolle sowie die Modellinferenz selbst.
