Subprocessors
Last updated 2 July 2026
Nexlyr AI is operated by Nexlyr Solutions Ltd. To deliver the service we rely on the providers below. Each processes data only for the role described, under its own data processing terms with the UK and EU approved safeguards for international transfers. Where each one stores or processes data is summarised on the data residency page.
