The figma.clientStorage API allows you to store data on the user's local machine. Unlike data stored with the document (such as <a href="/plugin-docs/api/properties/nodes-setplugindata">setPluginData), this data is not synchronized across users. It's similar to the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage">Window.localStorage API, but is asynchronous, and allows storing objects, arrays, strings, numbers, booleans, null, undefined and Uint8Array. Like localStorage, you should expect that user actions such as clearing the browser cache might clear all stored data.
