# API  Key

Popai stores your API keys locally in your browser's storage for security. The keys are never uploaded to Popai's servers or databases. This means:

* API keys are only stored on your local device
* Keys are automatically cleared when you clear browser cache/data
* Keys are removed when you log out of Popai
* You'll need to re-enter API keys after clearing cache or logging back in
* Each browser/device needs its own API key configuration

This design ensures your API keys remain private and under your control at all times.
