Plumbline: Lieu de fabrication ("the app") is provided by Plumbline Apps. This policy explains what the app accesses and stores when a merchant installs it. Last updated: October 25, 2026.
The app reads your products (title, handle, status and featured image) and reads and writes three product metafields that hold manufacturing places for weaving, dyeing and making. These metafields are stored in your Shopify store, not on our servers.
The app does not access, collect or store any personal data about your customers, such as names, emails, addresses or orders.
To keep you signed in, the app stores your shop domain and the access token Shopify issues at installation, in a database on our server. If you subscribe to a paid plan, Shopify handles billing; we only query your subscription status from Shopify.
The app server is hosted on Alibaba Cloud in Hong Kong. Connections are encrypted with TLS.
When you uninstall the app, your sessions and access token are deleted. When Shopify sends the shop redaction request after uninstall, any remaining data for your shop is deleted. Customer data requests require no action because the app holds no customer data. The manufacturing places you entered stay in your store as product metafields until you remove them.
You can ask us what we hold about your shop, or ask us to delete it, at any time. Contact: wuhoujin68@gmail.com. Plumbline Apps, Rm 1605, Unit 3, Bldg 6, Tianyue Jinlin B, Pukou, Nanjing, Jiangsu 211800, China.
