# How long are outputs maintained?

For a full breakdown of how AssemblyAI maintains audio and transcript data, see [Data retention and model training](/data-retention-and-model-training).

For Async STT, Final Transcription Artifacts (transcripts) are stored for **30 days by default and are automatically deleted after that**. You can shorten this window by setting a time-to-live (TTL) on the [Data Controls page](https://www.assemblyai.com/dashboard/settings/data-controls) in the dashboard — presets of 1 day, 3 days, 7 days, and 30 days are available, or you can set a **Custom** value. See [Set a time-to-live for audio and transcripts](/data-controls#set-a-time-to-live-for-audio-and-transcripts).

For customers with a BAA, all transcripts generated via the async transcription endpoint are deleted after the TTL period (currently set to 3 days by default).

You can also delete individual transcripts on demand via the [DELETE endpoint](/pre-recorded-audio/delete-transcripts).
