Privacy Policy

Last updated: April 2026

1. What We Collect

Concrepedia is a read-only knowledge base. We do not require account creation. The only data processed is anonymous chat messages sent to the AI assistant (powered by xAI Grok), which are stored temporarily in Redis with a 72-hour TTL for conversation context, then automatically deleted.

2. Chat Sessions

Chat sessions are identified by a randomly generated UUID stored in your browser's sessionStorage. This ID is never linked to your identity. Session history is purged automatically after 72 hours and is never sold or shared with third parties.

3. Third-Party Services

We use xAI for AI inference and Upstash Redis for ephemeral session storage. Both services process data under their own privacy policies. No personally identifiable information is transmitted to either service.

4. Cookies & Tracking

Concrepedia uses no tracking cookies, analytics pixels, or advertising networks. No personal data is collected, stored, or sold.

5. Contact
