Assessment

Voice agent platform: high

Reasoning: A voice-agent platform that handles phone calls with end customers. The policy lists training its AI models as a use of personal information and allows call recording for service improvement, with US processing. Call content is by nature sensitive; a contract that switches off training use is needed before production use with customer calls.

Flags: Policy lists AI model training as a use of personal information · Calls may be recorded for service improvement · US processing only · Assessed 2026-09-16. The assessment is Unseen's; the terms above are the vendor's.
