Your recordings stay your recordings
We never train AI models on your audio, and we never build voice clones, voice models or voice fingerprints from it. No exceptions, no fine print. Your upload is deleted as soon as processing finishes and your finished file is removed after the retention period, so if your work sits under an NDA or publisher agreement, it is safe here.
