FitChart (“we”, “us”, “our”) is a helper Shopify application that displays size charts on product pages. We operate internationally as a Shopify App Partner.
We help merchants optimize design, sizing setups, and user fit matching seamlessly. For questions, requests, or information regarding this privacy policy, you can contact us securely at our designated privacy inbox below:
From merchants (store owners)
When installing FitChart on your Shopify store, we collect details strictly mandatory to function and map correct customer size parameters:
- Store name and domain (e.g. storesupport.myshopify.com)
- Store owner email (provided securely by Shopify during app installation)
- Product and collection data (required to map specific size charts to your custom product pages)
- Theme data (necessary to configure Shopify App Blocks seamlessly in your storefront)
From shoppers (end customers)
FitChart does not collect any personal data from shoppers. The size chart widget acts as a pure display-only component on the front end. Our script does not read shopper cookies, check customer identifiers, or log customer names, emails, browsing history, or payment information. Everything is fully isolated and safe.
We use merchant data solely to carry out app features and honor our service commitments:
- Display the correct size chart on the correct product page matching variant criteria
- Store your chart configurations, dimensions, ratios, custom themes, and templates
- Send vital service messages (e.g. platform breaking changes, API upgrades, theme issues)
- Respond to emails or merchant-initiated customer support requests
We do not sell, rent, trade, or process merchant data for targeted advertising, scoring, automated decision profiling, or resale to secondary parties.
For individuals in the EEA (European Economic Area) and UK, we process merchant data relying on clear legal channels under Art. 6 GDPR:
| Processing Activity | Legal Basis | Article | Notes |
|---|---|---|---|
| Delivering app functionality | Performance of contract | Art. 6(1)(b) | Necessary to fetch sizes and embed the app blocks cleanly. |
| Storing merchant configuration | Performance of contract | Art. 6(1)(b) | Maintains chart configurations, styles, and templates. |
| Sending service emails | Legitimate interests | Art. 6(1)(f) | Transactional service updates, policy modifications, and downtime alerts. |
| Responding to support | Performance of contract | Art. 6(1)(b) | Fulfills merchant assistance requests and bug fixes. |
We preserve strict isolation. We do not sell, rent, or trade your data. To offer stable app hosting, we share restricted merchant details with:
- Shopify Inc. — mandatory to operate, execute payment flows, and interface via official endpoints.
- Email service provider — to dispatch critical updates or answers to support tickets.
- Hosting/infrastructure provider — to keep the database stable and launch the app shell dynamically.
* All third-party providers must adhere strictly with data protection agreements (DPAs) or standard contractual clauses in full compliance with GDPR mandates.
Merchant configuration details remain active only for the duration of the app installation.
Once a merchant uninstalls the App, we preserve data for exactly 30 days as a safety buffer. This ensures that if the action was accidental, or you decide to re-install, your custom templates are restored perfectly without permanent data loss.
Permanent Sanitization
Upon day 31 post-uninstall, all merchant credentials, domain names, stored configs, and size chart tables are permanently and irreversibly purged from our backups.
If you reside within the European Economic Area (EEA), United Kingdom (UK), or jurisdictions with similar legal protections, you enjoy the following rights:
Request a complete copy of any merchant data we preserve in active records.
Request correction of inaccurate or incomplete attributes in our databases.
Exercise the right to be forgotten (permanent deletion out of standard bounds).
Limit how and when we process specific segments of your merchant details.
Object to operations based solely on legitimate business interests.
Receive your data stored in a machine-readable, plain digital format.
To file any request please email: contact@fitchart.org. We resolve all legitimate requests within 30 days. You also hold the right to complain to your regional supervisory authority directly.
FitChart complies fully with mandatory Shopify GDPR webhook protocols. The platform alerts us automatically, yielding rapid sanitization:
| Webhook Topic | Our Response |
|---|---|

| shop/redact | Permanently delete all merchant data within 30 days after the 48-hour post-uninstall grace period |
