How to delete the app
For general information about deleting apps please refer to https://support.wix.com/en/article/deleting-apps, "Delete an app added to a page in the Editor".
Additionally:
1. Due to GDPR you should delete the Birthday Club customers from your WiX contact list, see how to delete a subscriber. Your customers have signed up and consented for Birthday Club only. You can access your customer list via your settings, click for more info.
2. If you have subscribed to a premium version you need to cancel your subscription, see https://support.wix.com/en/article/cancelling-an-app-subscription-4248715.
Your customer list is preserved so if you add back the App you'll get all your customer data back. We don't sell or share customer emails. If you want us to delete your customer list, email support@riiwards.com.
Once the App is disabled, automated reward emails are not sent any more. However, you may still have customers who were sent reward emails earlier and they will expect to get their reward.
