Privacy Policy
Last updated: September 2026
SegmentIQ is built by Marvel Labs. This policy explains what data we collect, how we use it, and your rights.
Data we collect
SegmentIQ accesses the following data from your Shopify store using read-only API permissions:
| Data type | What we access | Why |
|---|---|---|
| Orders | Order totals, discount amounts and codes, currency, dates (last 12 months, then new orders as they happen) | Calculate discount metrics per code and segment |
| Customers | Shopify customer IDs and segment membership | Link orders to segments and to earlier orders |
| Discounts | Discount names, types and statuses | Identify which discounts were used |
| Products | Basic product information | Context for discount analysis |
| Store contact details | Store name, contact email and owner name, read from Shopify when an email is sent | Send a welcome email after install, and one email after Black Friday–Cyber Monday about your own discount codes |
Data we do not collect or store
- No personal customer information — we store Shopify customer IDs only, never customer names, emails, addresses or phone numbers
- No payment information — we never access card or payment details
- No browsing data — we do not track your customers' browsing
- Your store contact details are not stored — they are read from Shopify only to send these emails
