It is required to see which tabs are open so we can find duplicates. We do not track or store your browsing history. Q: What data do you collect? A: None. Dr.Browser does not collect, transmit, or log any data. Everything stays on your device. Q: Can you see what websites I visit? 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.
