Yes, Figma plugins have their own dedicated local storage system called figma.clientStorage, which is specifically designed for plugin data persistence[1].

How Figma Plugin Storage Works

Plugin-Specific Storage: Each plugin gets its own isolated storage space that other plugins cannot access[1]. The data is specific to your plugin ID, ensuring complete separation between different plugins[1].

Storage Capacity: Each plugin receives 5MB of total storage space[1]. You can estimate usage by adding the size of keys plus their JSON-converted values[1].

Asynchronous API: Unlike regular localStorage, Figma's clientStorage uses asynchronous methods[1]:

• figma.clientStorage.setAsync(key, value) - Store data
• figma.clientStorage.getAsync(key) - Retrieve data
• figma.clientStorage.deleteAsync(key) - Remove data
• figma.clientStorage.keysAsync() - List all stored keys

Key Differences from Regular localStorage

No Standard localStorage Access: Figma plugins cannot use regular localStorage or parent.localStorage as these are prohibited in the plugin environment[3].

Data Types Supported: The clientStorage API can store objects, arrays, strings, numbers, booleans, null, undefined, and Uint8Array values[1].

User-Specific: Data is stored locally on the user's machine and is not synchronized across different users[1]. Each user running your plugin will have their own separate storage[5].

Example Usage

// Store user preferences
await figma.clientStorage.setAsync('userPrefs', { theme: 'dark', autoSave: true });

// Retrieve stored data
const prefs = await figma.clientStorage.getAsync('userPrefs');

// Delete data
await figma.clientStorage.deleteAsync('userPrefs');

Important Limitations: The data can become inaccessible if your plugin ID changes, and users can clear this data by clearing their browser cache[1]. The storage is designed for stability rather than security[1].
