# About Storage

There are three types of storage:

| Type | Persistence | Data Limit | Typical Usage |
|--------------|-------------|------------|-------------|
| **Local** | Data never expires and persists even when the site visitor closes the page. When the site visitor reopens the page later, the data can still be retrieved. | 50kb | Store site visitor state between sessions. |
| **Session** | Data is available while session is active. Once the browser tab or window closes, the data expires. Reloading the page or navigating to other pages doesn't affect session storage. | 1mb | Pass data between pages on the site. |
| **Memory** | Data expires when the site visitor closes or refreshes the current page, or navigates to a different page. | 1mb | 
Store data on the current page only. |
