Notes
AI language model providers receive conversation context to generate responses in real time. ProFront uses commercially reasonable measures to minimize the personal data included in these requests. These providers do not retain data beyond the scope of individual requests under our service agreements.
ProFront may route AI inference requests through multiple model providers depending on availability, performance, and configuration. All such providers operate under equivalent data handling commitments.
ProFront reviews subprocessors periodically and updates this page when providers are added, replaced, or removed. Material changes are communicated to customers via email or in-app notice.
