# 🗑️ Zero Data Retention (ZDR)

**Zero Data Retention (ZDR)** means that a provider does **not store your request or response data for any period of time**. When enabled, requests are routed **only to endpoints that guarantee zero data retention**, helping you meet strict privacy and regulatory requirements. 

> 💡 **Note:** Even when using providers that retain data for a limited period, **your data is never used for model training**. Retention, when applicable, is strictly for operational, security, or monitoring purposes.

## Via Web Console

1. Go to your [**Project Settings**](https://cortecs.ai/userArea/userProfile) **→ Inference Section**.
2. Toggle **Zero Data Retention** **ON** ✅ to route requests **only to endpoints with data retention = 0**.

3. Toggle **OFF** ❌ to allow routing to **all available endpoints**, including those with non-zero retention periods.

## Via API

You can also control this behavior directly in your requests using the `allow_zero_data_retention` parameter:

```json
{
  "model": "gpt-oss-120b",
  "messages": [...],
  "allow_zero_data_retention": true
}
```

* `true` ✅ → Requests are routed **only to Zero Data Retention endpoints**
* `false` ❌ → Requests may be routed to **all endpoints**, regardless of retention duration

For **project-wide enforcement**, you can also configure this setting via the [**Project Config API**](https://docs.cortecs.ai/advanced-usage/project-configuration/update-project-config), ensuring all team requests follow the same policy. 🏢

## &#x20;Compliance Focus

* **Zero Data Storage**: Ensures no request or response data is retained.
* **Privacy by Design**: Ideal for sensitive, regulated, or confidential workloads.
* **GDPR Compliance**: All endpoints comply with GDPR, regardless of retention duration.
* **Governance Control**: Can be enforced at the project level.

Zero Data Retention helps organizations minimize data exposure, simplify audits, and meet strict internal or regulatory privacy requirements without compromising GDPR compliance.
