What the refill is
The 30 day free refill is the one protection that comes with every package. If the DR or DA you bought drops below the purchased level within 30 days of delivery, BoostDADR redoes the work for free. You do not pay again for the same package.
Why is it needed? Ahrefs and Moz recalculate their numbers as their crawlers find and lose links. A figure that looks right on delivery day can move later, and that is outside anyone's control. The refill is your remedy if it happens during the first 30 days.
It is a service term. It is not a guarantee that the number stays, and it does not reach past the end of the window.
