storage: To save your user settings and the formula library locally on your device.
host_permissions (docs.google.com, sheets.google.com): To allow the extension to inject UI and run within the required Google Sheets environment.
When you choose to use the AI features and provide your own API keys, the extension facilitates direct communication between your browser and the respective third-party service:
