Our GDPR application is not storing any personal data from your customers. Any data that we provide through our application are coming directly by the shopify api.
We only store some basic information about your store as long as the preferences of your application.
For purposes of clarity when you uninstall the application we delete all the data we store for your store and any activities related to the application. This means that if you re-install the application you start from scratch.
Finally any email that is sent from the application to the merchant and the customers of your store does not include any personal information either.
