1. Information We Collect
Account Information
When you create an account, we collect your email address and any profile details you provide (such as a display name). Account authentication is handled by Clerk, Inc. We do not store your password directly — Clerk manages credential security on our behalf.
Golf Performance Data
When you use our iron-matching tool, we collect carry distances you enter for each iron (e.g., 7-iron carry in yards), your self-reported swing speed range, and your handicap range. This data is stored to generate and display your match results and may be used in aggregate (anonymized) form to improve our recommendation algorithms.

Your Right to Opt Out (CCPA)
Under the California Consumer Privacy Act (CCPA), you have the right to opt out of the collection and use of your personal information for analytics purposes. We use Google Analytics to understand aggregate usage patterns. To opt out, you can install the Google Analytics Opt-out Browser Add-on or adjust your browser's cookie settings.
