How We Use Your Data

Data Storage & Security

Conversation history is stored in Redis with a 30-day retention period. After 30 days of inactivity, your session data is automatically deleted.

Security measures include HTTPS/WSS encryption, API key authentication, Firebase Authentication, and no storage of raw audio recordings.

AI Conversations & Memory

Sympy is powered by OpenAI's GPT-4o models. Messages are transmitted to OpenAI's servers for processing. See OpenAI's Privacy Policy for details.

Your conversation history helps the AI remember your preferences and generate summaries. Images sent during chat are processed by GPT-4o vision and are not stored after processing.
