Privacy Policy
SizeMe is a size-recommendation app for stores on the OpoShop platform, published by Found. This policy explains what data SizeMe collects, how it’s used, and how it’s protected. SizeMe is designed to be data-minimal by default.
1. Data we collect
From the merchant (via OpoShop OAuth): when you install SizeMe, OpoShop grants us a store-scoped access token and your store’s identifier and subdomain. We use these only to confirm the store is yours and to display your store name in the widget. We request the least access we need: read access to products and your store profile.
From your public storefront: to pick the right size chart for a product and to list your products in the app, SizeMe reads your store’s public product pages and collection lists, the same information any shopper’s browser loads: product names, size options, stock, and which collections a product is in. No login or token is used for this.
Your configuration: the size charts, fit models, quiz questions, widget and branding settings you create, and any per-product choices you make (which chart a product uses, or that it shows no button). This is your merchant data, scoped to your store.
From shoppers using the quiz: a shopper’s answers (height/weight, measurements, usual size, fit preference) are sent to our server only to compute a size recommendation. We do not persist those answers. What we keep is de-identified: the recommended size, a confidence score, which signal drove it, the product it was for (your product id, not the shopper), whether the size was then selected on the page, and the day. We also keep daily totals of how many times the Find my size button was shown on your product pages and how many times the quiz was opened, and the time the button was last shown. These are counts only. No shopper name, email, IP-based identity, or raw measurement is stored. A shopper’s IP address is held in memory for up to one minute to limit abuse of the quiz. It is not saved to our database and is not linked to any answer.
2. How we use data
- To generate a size recommendation and select the matching variant on your product page.
- To show you dashboard counts: how often the button was shown, quizzes opened and finished, the sizes suggested most, how close the matches were, and how often the suggested size was selected on the page.
- To operate, secure, and improve the app.
We do not sell data, and we do not use shopper data for advertising or profiling.
3. Payment & card data
SizeMe never touches payment or card data. It does not process, store, or transmit any payment information. All checkout and payment happens within OpoShop.
4. Storage & retention
Configuration and de-identified analytics are stored in SizeMe’s own database, scoped per store, on managed infrastructure (MongoDB Atlas). Your store’s access token is stored to make API calls on your behalf while SizeMe is installed.
When you uninstall SizeMe, OpoShop cancels the access token and tells us. We then check with OpoShop that the app really was removed. Once OpoShop confirms it, we delete our saved copy of your store’s access token and the size finder stops showing on your store. Your size charts, product choices, settings and counts are kept, so that reinstalling brings them back. To have them deleted, email us and we will delete them and confirm it.
The de-identified quiz results behind your dashboard (size, confidence, product, day) are deleted automatically 13 months after they are recorded. You may ask for earlier deletion at any time.
5. Product analytics
We use PostHog to understand how the app is used (e.g. a merchant saved a size chart, a quiz was completed). These events are tagged to your store by its OpoShop identifier and never include shopper personal data or raw measurements.
6. Sub-processors
- Fly.io: application hosting.
- MongoDB Atlas: database.
- PostHog: de-identified product analytics.
- OpoShop: the platform SizeMe runs on; product reads use its API.
7. Your rights & uninstalling
Uninstalling SizeMe from your OpoShop admin ends our access to your store. Section 4 says exactly what is deleted when you do. To request an export or deletion of your store’s configuration or counts at any other time, contact us and we will do it promptly.
