Your practice audio never leaves your device. It's scored on your device — in the app on your phone, or in your browser on the web — so recordings are never sent to CaseBrick or to any provider above; only the text a given feature needs is. For the full detail on what each provider receives, see our Privacy Policy. Questions: support@casebrick.com.
