No Retention: We do not store face data on our servers, nor do we allow any third party to store it.

No Sharing: Face data is not shared with any third parties other than OpenAI for processing purposes, and OpenAI does not store the data.

Purpose: The sole purpose of processing face data is to provide the user with AI-powered skin analysis and antioxidant index results.
