• No Persistent Storage: We don't save your selected text or interactions on our servers permanently
• ActiveTab Permission: We only access the current webpage you're viewing (not your entire browsing history)
• Domain-Specific Tracking: Extension state is tracked per domain, providing granular control

6. User Controls and Rights
