If you prefer to check in without receiving the daily push notification, you can pause notifications in the Manage Rx Check-Ins page, which can be accessed by clicking on the edit / pencil icon in the Rewards hub. Doing so will not prohibit you from completing an Rx Check-In on your own each day.
If you need a break from tracking your medications, you can turn off check-ins entirely in the Manage Rx Check-Ins page. You can resume at any time from the Rewards hub.
You can resume notifications at any time from the Rewards hub in the GoodRx app.
