CxCheck is offered in two deployment modes. Sovereign Hosted is the standard service: your project data is stored and processed on infrastructure CxCheck owns and controls, with document analysis running on locally hosted models. On-Site Node is available for approved enterprise projects: dedicated hardware operated inside your own facility, licensed on a subscription basis. In both modes your documents are never sent to third-party AI providers and are never used to train any model.

Document analysis runs on inference hardware CxCheck owns and controls, using locally hosted models. No third-party AI provider is a subprocessor for document analysis, and no documents are sent to hosted model APIs.

Each organization's data is isolated by row-level security and role-based permissions. Project records, uploads and analysis results are scoped to the owning organization and are not visible to other tenants.

Model training is not performed on customer data. No project documents are used to train, fine-tune or improve any model, and no training data is derived from your project records.
