Data we store
- Your store's access token. When you install Billow, Shopify gives the app an access token for your store. We store it with your shop domain and the granted permissions, so the app can save your settings and create the free gift discount.
- Your settings (design, thresholds, texts, chosen products) are saved in your own Shopify store, as app metafields. They are not copied to our server.
Data we do not collect
- We do not collect, store or process any data about your customers: no names, emails, addresses, orders or payment details.
- The cart drawer runs in your shoppers' browsers and talks only to your Shopify store. It never sends data to our server, and it sets no cookies. It keeps one value in the browser session (whether the shopper removed the free gift), deleted when the tab closes.
- We do not use analytics, advertising or tracking tools.
Retention and deletion
When you uninstall Billow, we delete your access token and shop record. We also honor Shopify's data deletion requests (shop/redact, customers/redact). Settings stored as metafields stay in your store until you delete them or the store.
Sharing
We do not sell or share your data. Billing is handled by Shopify.
