    ❓ FREQUENTLY ASKED QUESTIONS
    
    Q: Why does Chrome show "Read your browsing history"?
    A: Chrome shows this warning for ANY extension that uses the "tabs" permission. This is required to see what tabs you have open so we can find duplicates. We DO NOT track or store your browsing history.
    
    Q: What data do you collect?
    A: NONE. Zero. We don't collect, track, or transmit any data. Everything stays on your device.
    
    Q: Can you see what websites I visit?
    A: Dr.Browser only reads tab information when you click the extension icon. We never track or log your browsing activity.
    
    Q: Is my data safe?
    A: 100%. All tab management happens locally on your device. We don't even have servers to send data to!

    A: Dr.Browser reads tab URLs only at the moment you open the popup or when the background alarm runs. We never log or store this information.
    Q: Will auto-suspend lose my work?
    A: No. Chrome's native tab discard preserves the tab in your browser — clicking it reloads the page. It is equivalent to the browser's built-in memory saving feature.
    Q: What is the default suspend time?
    A: 10 minutes of inactivity. You can change this to any value between 1 and 480 minutes in Settings.
