QuantaraSubprocessor and Service Provider Information
Last updated: 24 August 2026
This page identifies infrastructure and optional service-provider categories used by Quantara. The providers that apply depend on the active service configuration and workflows selected by the customer.
A provider is used only when the relevant infrastructure is active or an optional user workflow is enabled. Inclusion here does not claim that every provider processes every customer's data.

Not listed as an active provider
Arcade and planned CAD, BIM, Autodesk or other integration providers are not listed as active subprocessors because no production-backed configuration is enabled in the current provider registry.
Changes and customer terms
Material provider changes will be reflected on this page. Where a customer agreement requires notice or an objection process, that agreement controls.
Google Drive and WhatsApp may also be user-chosen external services. Their legal classification and any customer-specific processing terms require owner or legal confirmation.
