Multi Tier Discounts by E-Kinco Co., Ltd.

Last updated: April 13, 2026

Overview

This Privacy Policy describes how Multi Tier Discounts ("the App") collects, uses, and shares information when you use our Shopify application.

We are committed to protecting your privacy. This app operates primarily through Shopify Functions and does not store customer data on our own servers.

Information We Collect

Store Information: We collect your Shopify store domain, access token, and basic store settings necessary to operate the App.

Customer Metafields: The App reads the following customer metafields at checkout to calculate discounts:

custom.discount_rate_1 ~ custom.discount_rate_4
custom.discount_name_1 ~ custom.discount_name_4

The App compares all discount rates (discount_rate_1 through discount_rate_4) and automatically applies the highest rate at checkout. The discount label displayed to the customer is taken from the corresponding discount_name metafield of that highest rate. For example, if discount_rate_2 has the highest value, the App applies that rate and uses discount_name_2 as the discount label.

This data is processed in real-time and is not stored on our servers.

How We Use Your Information

Data Storage & Sharing

The App operates through Shopify Functions running on Shopify's infrastructure. We do not store customer data on our own servers.
