title: saveStore (KSAVE)
---
## Summary
Save an option [`store`](/developer/language/guide/stores) value to a cookie for the active keyboard.
## Syntax
```js
keyman.interface.saveStore(storeName, value);
```
or
```js
KeymanWeb.KSAVE(storeName, value); // Shorthand
```
### Parameters
`storeName`
: Type: `string`
: The option `store` name, which will be embedded in the cookie's name.
`value`
: Type: `string`
: The option value to save.
### Return Value
`boolean`
: `true` if the operation is successful, otherwise `false`.
## Description
[`keyman.interface.loadStore()`](loadStore) and `keyman.interface.saveStore()`provide API-based functionality similar to that of the keyboard language's option `store`. Values will persist across multiple visits to the site by use of cookies. However, these functions cannot interact with `store`s from existing compiled keyboards due to compilation optimizations. As such, they are most useful for custom-coded web-oriented keyboards.
