When you interact with the PREVA AI Companion, conversational data is processed through the Cognitive Memory System. This is not cookie-based tracking — it is a core Service function governed by the EULA and Privacy Policy.
The AI Companion adapts to your preferences and communication style. This personalization:
PREVA does not use cookies or any tracking technology to analyze facial expressions, voice tone, or physiological signals; infer emotions from biometric data; or create biometric profiles. All emotional awareness is derived solely from text-based analysis.
