This policy applies to every Shelfworks app: Backstock, Convertback, Shelfcheck, Flowkit, Labelpress, Mergerate, Retrybill and Editback ("the apps"), developed by Shelfworks ("we"). It explains what an app stores when a merchant installs it on their Shopify store.
When you install an app, we receive the access token Shopify issues so the app can read and write the data its permissions describe. Depending on the app, we store:
We do not sell or share this data with third parties, except the email delivery provider used to send alerts you configured.
Data is kept while the app is installed. Sessions are removed when you uninstall. All remaining data for your store is deleted when Shopify sends the shop redaction request, 48 hours after uninstall, or sooner on request.
We respond to Shopify's customer data request and customer redaction webhooks. Where an app stores a customer's name or email, it is deleted on redaction.
