Each sub-processor has their own privacy policy and processes data only as necessary to provide the service.

7. Cookies
We use localStorage (not cookies) to store your authentication tokens locally on your device. We do not use advertising or tracking cookies. We may use first-party analytics in future.
8. Security
Passwords are hashed using bcrypt. Authentication uses short-lived JWT access tokens (1 hour) and 7-day refresh tokens. HTTPS is enforced in production. Audio files and transcripts are stored in access-controlled cloud storage.
