The duration of the ScanCredits in PlagAware differs concerning the subscription plan or package bought. Most of the time, ScanCredits do not expire as long as the subscriber is active. However, the expiry of the remaining ScanCredits may depend on the dedicated plan when the subscription is not active or is cancelled. It is advisable to read the particulars of your plan because, in some scenarios, the unused ScanCredits could be eligible for a rollover while in some instances, they will be lost at the end of the subscription term.
