Data storage and security
We implement industry-standard security measures to protect your data:

- Local storage: Your API key is stored locally on your device using Chrome's storage API
- Password security: Passwords are hashed before storage
- Access control: We implement strict access controls to limit who can access your data
Chrome extension permissions
Our Chrome extension requests the following permissions, which are used exclusively for the stated purposes:
- activeTab
- Used to access the current tab when you activate the element picker to select HTML elements on your webpage.
- storage
- Used to store your Cueston API key locally on your device.
- tabs
- Used to open the Cueston dashboard in a new tab and verify URLs to prevent operation on restricted pages.
- scripting
- Used to inject the element picker script when you explicitly activate the picker feature.
- <all_urls> (host permissions)
