# Data Retention

> What Prem API stores, what it never stores, and how you can verify the policy.

<Info>
  **The policy in one sentence:** Prem API does not store your prompts, completions, or audio after it returns the response. The platform keeps zero inference content.
</Info>

## What Prem API never stores

The platform does not retain inference content:

* **Prompts and messages**: not stored after the response
* **Completions and model output**: not stored after the response
* **Audio for transcription and translation**: not stored after the response

The encrypted inference endpoints are named RVENC: raw **volatile** encrypted. Your content exists inside the enclave only in volatile memory, for the duration of the request. See [How It Works](/how-it-works) for the request lifecycle.

## What Prem API stores

Some data is necessary to operate the platform:

* **Files that you upload**: The platform stores files that you upload to the file endpoints. The files are encrypted with your keys. Only you can decrypt them. You can delete them at any time. See [Encryption](/encryption).
* **Request metadata**: The gateway records the time of each request, the payload size, the API key, and the rate limit counters. Prem uses this metadata for billing, rate limits, and analytics. The metadata does not include your content. See the [Security Model](/security-model).
* **Error traces**: Error responses include a `support_id`. Prem keeps the trace for that identifier for up to one week. See [Errors](/errors).

## Why you do not have to trust this page

Most providers publish a retention policy and ask you to trust it. Prem API adds two verifiable protections:

1. **The platform cannot read your content.** Your device encrypts all content before it leaves. The gateway routes only encrypted bytes. Decryption happens only inside the sealed enclave. A stored copy of your traffic would be useless ciphertext. See [Encryption](/encryption).
2. **You can verify the enclave code.** Attestation proves which code runs inside the enclave. See [Attestation](/attestation).
