No, the UpStackified Shopify app does not store or keep any of your customer data. The app is designed to work within the Shopify ecosystem, and all data is collected and stored by Shopify.

When you install the app, you will be asked to grant permissions for the app to access certain data from your Shopify store, such as product information and order details. However, this data is only used by the app to provide its services, such as tracking conversion events and optimizing your advertising campaigns.

UpStackified is committed to protecting your privacy and data security. The app is compliant with GDPR and other data privacy regulations, and all data is transmitted securely using industry-standard encryption protocols.

If you have any concerns about how your data is being used, you can contact the UpStackified support team for more information or to request that your data be deleted.
