All customer measurement data is stored anonymously and cannot be linked back to individual customers.

We do not collect customer names, email addresses, shipping addresses, payment information, or any other personally identifiable information from storefront visitors. All customer measurement data is stored anonymously and cannot be linked back to individual customers.
Section 02
How We Use Information
We use the information we collect solely to provide and improve our size recommendation service:
We do not sell, rent, or share your information with third parties for marketing purposes. We do not use customer measurement data for any purpose other than providing size recommendations and anonymous analytics to merchants.
- Merchant store information is used to authenticate your account, manage your subscription, and deliver size recommendations on your storefront
- Customer measurement data is used to calculate and provide instant size recommendations
- Aggregate measurement data helps merchants understand sizing trends and popular size distributions
We do not sell, rent, or share your information with third parties for marketing purposes. We do not use customer measurement data for any purpose other than providing size recommendations and anonymous analytics to merchants.
Section 03
Data Storage and Security
All data is stored securely on servers hosted by Railway, a trusted cloud infrastructure provider, with databases managed through PostgreSQL. We implement industry-standard security measures including:
While we take reasonable precautions to protect your information, no method of electronic transmission or storage is completely secure, and we cannot guarantee absolute security.
- Encrypted connections (HTTPS/TLS)
- Secure authentication through Shopify’s OAuth system
- Access controls to protect your data
- Shopify session data stored securely and managed according to Shopify’s security requirements
While we take reasonable precautions to protect your information, no method of electronic transmission or storage is completely secure, and we cannot guarantee absolute security.
Section 04
Data Retention
We retain merchant account data for as long as the App remains installed on your Shopify store. When you uninstall FitLogic:
For customer measurement data, we retain anonymous recommendation logs to provide merchants with analytics. Since this data contains no personally identifiable information and cannot be linked to individual customers, it poses no privacy risk. Merchants on paid plans can view aggregate analytics of this data through their dashboard.
- Your session data is immediately removed
- Within 48 hours of uninstallation, when we receive Shopify’s shop redaction webhook, we permanently delete all associated data including your shop record, all size charts, all size entries, and all recommendation logs

Section 05
GDPR and Data Protection Compliance
FitLogic is fully compliant with the General Data Protection Regulation (GDPR) and Shopify’s mandatory privacy requirements. We respond to all Shopify compliance webhooks:
Since FitLogic does not store any personally identifiable customer information or link measurement data to customer accounts, there is no personal data to export or delete. All measurement data we collect is anonymous by design. For merchants in the European Economic Area, Middle East, or other regions with data protection regulations, our data minimization approach ensures compliance by collecting only what is necessary for the service to function.
- customers/data_request — customer data access requests
- customers/redact — customer data redaction requests
- shop/redact — shop data deletion requests
Since FitLogic does not store any personally identifiable customer information or link measurement data to customer accounts, there is no personal data to export or delete.

Section 06
Third-Party Services
FitLogic integrates exclusively with Shopify and does not share data with any other third-party services:
The only data transmission that occurs is between your Shopify store, our secure servers, and back to your storefront to display size recommendations.
- We use Shopify’s Billing API to process subscription payments — we never directly access or store your payment information
- All payment processing is handled securely by Shopify
- We do not use third-party analytics services, advertising networks, or any external tools that would have access to merchant or customer data
The only data transmission that occurs is between your Shopify store, our secure servers, and back to your storefront to display size recommendations.
Section 07
Cookies and Tracking
FitLogic does not use cookies to track customers on merchant storefronts. The size recommendation widget operates entirely through direct API calls and does not store any information in the customer’s browser. For merchants using the FitLogic admin dashboard within Shopify, standard Shopify session management applies as governed by Shopify’s own privacy policy.
Section 08
Children’s Privacy
FitLogic is not directed at children under the age of 13, and we do not knowingly collect information from children. The App is designed for use by Shopify merchants and their adult customers. If you believe we have inadvertently collected information from a child, please contact us immediately and we will take steps to delete such information.
