# Understanding data retention for Amazon Chime SDK voice analytics
<a name="va-data-retention"></a>

By default, Amazon Chime SDK voice analytics deletes voice embeddings after 3 years. We do this because people’s voices change over time, and also for security. You can use the [https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_voice-chime_UpdateVoiceProfile.html](https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_voice-chime_UpdateVoiceProfile.html) API to update expired voice embeddings.
