License keys
After buying Lifetime Pro, copy the license key from your Gumroad receipt, open DupTabOff's settings, click "Enter key" and paste it. One key works on up to 5 browsers. If a key says it's used on too many browsers, reply to your receipt email and we'll reset it.
Refunds
If Pro doesn't work for you, email us within 14 days of buying and we'll refund you. After 14 days, refunds are at our discretion, and your rights under your country's consumer law always apply.
Getting tabs back
Chrome itself can reopen recently closed tabs: press Ctrl+Shift+T (Cmd+Shift+T on Mac). With Pro, DupTabOff's Undo button brings back a whole batch in the windows they came from.
Common questions
