Privacy Policy

Last updated: January 14, 2026

This Privacy Policy explains how OneX Engineering (also referred to as "1x Engineering," "we," "us," or "our") collects, uses, and protects information when you visit or make a purchase from onexengineering.com (the "Site").

We are committed to data minimization and transparency. We collect only the information necessary to process orders and operate the Site. We use Google Ads conversion tracking and Meta Pixel to measure the effectiveness of our advertising campaigns.

1. Who We Are

OneX Engineering operates an e-commerce website selling sustainably sourced, Japanese-imported clothing. Proceeds from sales help fund software development projects and charitable donations.

For privacy-related questions, you may contact us at: [email protected]

2. Information We Collect

Information Collected During Checkout

When you place an order, certain personal information is collected through our third-party payment processor (Square), including:

  • Full name
  • Email address (for order confirmation and support)
  • Shipping address (U.S. addresses only)
  • Optional phone number (provided by payment wallets such as Apple Pay or Google Pay)

Payment information such as credit or debit card numbers is processed entirely by Square. We do not store or have access to full payment details.

Non-Personal Information

We use browser localStorage (not traditional cookies) to store non-personal information directly on your device, including:

  • Shopping cart contents
  • Theme preference (light or dark mode)
  • Measurement units (metric or imperial)
  • UI state preferences (such as size chart visibility)

This information remains on your device and is not transmitted to our servers unless you complete a purchase.

3. How We Use Information

  • To process and fulfill orders
  • To calculate taxes and shipping
  • To send order confirmations and transactional emails
  • To provide customer support
  • To comply with legal and tax obligations

Aggregated and anonymized order totals may be used to calculate charitable donations. No personal information is shared or published for this purpose.

4. Sharing of Information

We do not sell, rent, or trade personal information. Information may be shared only with the following service providers:

  • Square: Payment processing, order management, fraud prevention, and tax handling
  • Email service providers: Used solely to send transactional order confirmations

These providers process data under their own privacy policies and applicable laws.

5. Data Retention

We do not store personal data on our own servers. Order information is retained by Square for accounting, tax, and legal compliance purposes. Local storage data remains on your device until you clear it.

6. Your Rights

Depending on your location, you may have rights to access, correct, or delete personal information. Because we do not store personal data directly, requests may need to be directed to Square. You may contact us for assistance.

7. Children’s Privacy

The Site is not intended for children under the age of 18. We do not knowingly collect personal information from children.

8. Cookies and Tracking

We use Google Ads conversion tracking and Meta Pixel (Facebook Pixel) to measure the effectiveness of our advertising campaigns. These tools use cookies or similar technologies to collect information about your interactions with our Site, including page views and conversion events.

  • Google Ads: Tracks conversions and ad performance. For more information, see Google's Privacy Policy.
  • Meta Pixel: Tracks page views and conversions for Facebook and Instagram advertising. For more information, see Meta's Data Policy.

You can opt out of personalized advertising by adjusting your browser settings, using ad blocker extensions, or visiting industry opt-out pages such as the Digital Advertising Alliance (DAA) or Network Advertising Initiative (NAI).

9. Changes to This Policy

We may update this Privacy Policy from time to time. Updates will be posted on this page with a revised "Last updated" date.
