# Privacy

> How Lumenfall and providers handle your data

Lumenfall is committed to protecting your data. This page explains what data we collect and how the providers that power our platform handle your prompts and generated content.

## Lumenfall

### What we collect

Lumenfall collects **metadata only** - we do not store your prompts or generated responses, except if you tell us to.

For each request, we log:

* Timestamp and latency breakdown
* Model and modality
* Provider selected (including fallback attempts)
* Endpoint called
* Response status code
* Cost and pricing breakdown
* Request and response sizes
* Usage metrics (token counts)
* Client IP region and processing location
* API key identifier (not the key itself)
* Error messages (if the request failed)

### What we don't collect

* **Prompts:** Your input text is never stored
* **Responses:** Generated images and outputs are not retained
* **Uploaded files:** Image inputs for editing requests are not stored

### Exception: Logging of upstream errors

When requests to providers fail, we will store error **responses** to help you debug. You can see the outputs in the dashboard. These error responses do not contain generated media.

## Providers

When you make a request through Lumenfall, your prompt is sent directly to the underlying provider. Each provider has their own policies around data retention and training on inputs.

<Warning>
  This table is provided for convenience only - we do not guarantee its accuracy. Provider policies may change at any time. Always consult the provider's official documentation directly for authoritative and up-to-date information.
</Warning>
