To provide transcription services, Gladia processes several types of data:
  • Audio input: Audio files or audio streams provided for transcription
  • Transcription output: Text, timestamps, words, utterances
  • API Metadata: Request IDs, timestamps, processing status
  • Logs: Operational logs for system reliability
The duration for which your data is stored depends on your plan type. You have two main options for data retention:
  • Standard data retention: Your data (such as audio files, transcripts, and metadata) remains accessible for a set number of days, up to a maximum allowed by your plan. The minimum retention value is 0, which means your data is deleted within 24 hours. The maximum and default value is 12 months.
  • Zero data retention: Data storage is minimized at all stages, avoiding temporary storage whenever possible. All data is deleted immediately after processing.
Only Enterprise users are eligible for custom data retention and the zero data retention option.
To enable usage tracking, Gladia retains essential API metadata: request ID, timestamp, processing status and audio duration. Immutable logs are also maintained, for a limited period, to ensure service quality and reliability.

Zero Data Retention behavior

When Zero Data Retention is enabled, Gladia processes data ephemerally; no data is stored at rest.
  • No audio files are stored: Files cannot be retrieved through the API or in the Gladia’s playground. File upload is also disabled; the asynchronous API must use an external audio file url, such as S3 presigned url.
  • No transcripts are stored: Transcription results cannot be retrieved through the API and are not visible in the Gladia’s playground.
  • No metadata retrieval: Transcription API calls, audio duration, and other metadata cannot be retrieved through the API or in the Gladia’s playground.
  • Transcription results delivered only via callbacks: The only way to receive transcription results is through callbacks; they cannot be retrieved by any other means.
Once the result is delivered, the audio, transcript, and metadata cannot be accessed.
