Privacy policy
Sizely is a Shopify app by HashCode FZE that recommends clothing sizes and shows how a size fits. This policy explains what personal data the app processes, why, and for how long. The merchant who installed Sizely is the controller of their customers' data; HashCode FZE processes it on the merchant's behalf.
What we collect and why
| Data | Why | Kept for |
|---|---|---|
| Shopper's size answers: sex, height, weight, age band, body shape, tummy, hips, fit preference, and optional chest or garment measurements | To recommend a size and show how it fits | In the shopper's browser only, until they clear it |
| For orders placed after using the size finder: order and line item number, product, size bought, size recommended, the answers above, and whether the item was returned too small or too large | To learn how each brand's sizes really fit and improve future recommendations for that store | 18 months, then deleted automatically |
| For other orders of products that have a size guide: order and line item number, product, size bought, and whether the item was returned. No answers | To show the store how return rates compare with and without the size finder | 18 months, then deleted automatically |
| Merchant's size guides, product assignments and settings | To run the app for the store | Until the store uninstalls, then deleted within 48 hours of Shopify's request |
| Size chart images a merchant uploads | Read once by an AI model (Google Gemini) to fill in the size table | Not stored after reading |
What we never collect
We do not collect or store customer names, email addresses, phone numbers, postal addresses, payment details or photos. We do not use cookies for tracking.
Consent
Answers are only used when a shopper chooses to use the size finder. If a shopper declines analytics in the store's cookie banner, their answers are not attached to their order and are not used for learning.
Sharing
We do not sell personal data or share it for advertising. Data is processed by our hosting and database providers, who are bound by confidentiality and security obligations. Size chart images uploaded by merchants are sent to Google's Gemini API to be read; they contain no customer data.
Automated decisions
The size recommendation is a suggestion. Shoppers always choose their own size, and the recommendation has no legal or similarly significant effect.
Security and retention
All data is encrypted in transit (HTTPS) and stored in an encrypted database. Order-level fit records are deleted after 18 months. All data for a store is deleted when Shopify sends the shop redaction request after uninstall, and a customer's records are deleted when Shopify sends a customer redaction request.
Your rights
Shoppers can ask the store they bought from to access or delete their data; the store forwards the request through Shopify and we act on it. You can also contact us directly at privacy@usesizely.com.
