Terms of Service

Audiex Pro is a prepaid transcription service. Usage is measured in processed audio seconds, one second is deducted per real second transcribed with a minimum of one second per request, and unused seconds expire after 3, 6, 9, or 12 months depending on the plan purchased.

Refund Policy

If the service does not meet your expectations, we offer a 14-day refund for unused seconds. Requests are reviewed against account activity and the remaining seconds on the account.

Privacy & Compliance

Audio is deleted immediately after transcription. All API communication requires HTTPS. We do not retain voice data persistently, and the handling model is designed around GDPR and CCPA data-minimization and deletion principles.
