Privacy policy
Effective 18 October 2026.
Tierup: Quantity Breaks (“the app”) is provided by Prince Sinha. It lets Shopify merchants offer tiered quantity discounts. This policy explains what the app collects when a merchant installs it and how that information is used.
What we collect
| Information | Why |
|---|---|
| The store's myshopify domain and install dates | To know which store an offer belongs to. |
| A Shopify access token, stored encrypted | To create and update the store's discounts on the merchant's behalf. |
| Offer settings the merchant enters: titles, tiers, products or collections, dates | To run the discount at checkout and show the tier table on product pages. |
| How many orders used each offer, as reported by Shopify | To show the merchant how their offers perform. |
The app does not collect, store or process personal information about the store's customers. It does not read orders or customer records, and the storefront block sets no cookies and does no tracking. Shopify access is limited to reading products and managing discounts.
Where it is stored
Data is stored in the United States with Google Cloud Platform (hosting) and Neon (database). Both act only as service providers. We do not sell or share data with anyone else.
How long we keep it
When a merchant uninstalls the app, Shopify deactivates its discounts and the access token stops working. All of the store's data is deleted when Shopify sends its data-erasure request, 48 hours after uninstall. Merchants can ask for deletion sooner by emailing us.
Your rights
Merchants can ask what data we hold about their store, or ask us to correct or delete it, by emailing princesinha7072@gmail.com. We also honour Shopify's privacy requests (customer data requests, customer erasure and shop erasure).
Changes
If this policy changes, we will update this page and its effective date.
