We do not sell your personal information.

Your data is stored on secure servers provided by Supabase (PostgreSQL database and file storage) and Upstash (Redis cache). Voice recordings from your practice sessions are retained in Supabase Storage so you can review past sessions in your history; access links to individual recordings expire after a short period and are refreshed automatically when you revisit a session. We use industry-standard encryption for data in transit (HTTPS/TLS) and at rest. We implement access controls and regular security reviews.
