Privacy Policy

Last updated: 2026-08-12

1. What we collect

To generate your adapter and process your order, we collect: the measurements you enter, your email address (for order confirmation and download links), your locale/unit preferences, and — if you create an account — basic authentication data via Firebase Authentication.

2. Payment data

Payment card details are collected and processed directly by Paddle, our payment provider and merchant of record. We never receive or store your full card number.

3. How we use your data

We use your data to generate your design, deliver fit-test and final files, send order and download emails, provide customer support, and improve the service. We do not sell your personal data.

4. Storage and retention

Design parameters, generated files, and order records are stored securely (Firebase Firestore and Storage) and retained for as long as needed to provide downloads, regenerations, and support, or as required by law.

5. Cookies and analytics

We use a minimal cookie to remember your language preference (English/Korean) and, where applicable, session identifiers required for checkout and abuse prevention. We use PostHog for product analytics (page views, feature usage, and, where enabled, anonymized session recordings to understand how the measurement wizard is used) and Google Ads to measure the performance of our own advertising campaigns, including conversion tracking. These tools may set cookies or similar identifiers. We do not sell your data to advertisers or use these tools to build advertising profiles for third parties.

6. Your rights

Depending on your location (including under GDPR for EU/UK users), you may have the right to access, correct, export, or delete your personal data. Contact hyetaeknavi@gmail.com to exercise these rights.

7. International transfers

Our infrastructure providers (including Firebase/Google Cloud and Paddle) may process data outside your country of residence, under appropriate safeguards.
