 # The Unleash Proxy
 
 The Unleash proxy offers a way to use Unleash in client-side applications, such as single-page and native apps. The Unleash proxy sits between the Unleash API and your client-side SDK and does the evaluation of feature toggles for your client-side SDK. This way, you can keep your configuration private and secure, while still allowing your client-side apps to use Unleash's features.
