This page lists the sub-processors Curvestone uses to process Customer Data, as defined in our agreements. Each one receives only the data it needs to perform its function, and model training is disabled across every AI provider we use. Transfers outside the UK are made under the mechanism set out in our Data Processing Agreement. Contact dpo@curvestone.io to request more information.
