About us

Geometry beats guesswork

⛳ We are a small crew of golfers and tinkerers who got tired of hearing "feel it" when the ball kept curving right.

🎯 Our mission is simple: turn biomechanical swing metrics into a clear, stress-free routine that coaches, fitters and weekend players can all read.

📐 SwingFit gives you a visual physics canvas to tune swing path, face angle, loft and spin, so slices, hooks and mismatched clubs finally make sense, with no connection required.

🏌️ Know your arc. Own your angle.

Privacy Policy

Effective Date: October 2026

SwingFit: Golf Arc & Angle is built to work entirely on your device. In short: we do not collect, store or share any data about you, your swings or your clubs.

1. Information We Collect

None. The app does not ask for, record or transmit personal details, swing metrics, location, device identifiers or usage statistics.

2. How We Use Information

Because nothing is collected, nothing is analyzed, profiled, sold or rented. Calculations such as carry, apex and launch efficiency happen on your device only.

3. Data Storage

Club profiles and setup logs you create stay in the app's local storage on your device. There is no cloud, no server and no backup copy on our side.

4. Third-Party Services

SwingFit contains no third-party analytics, advertising networks, social plug-ins or trackers, and it makes no network requests to run.

5. Data Security

As all processing is local and offline, there is no data in transit to intercept. Your saved profiles are protected by your device's own security features.

6. Children's Privacy

The app is COPPA-friendly. We collect no data from anyone, including children under 13, so there is nothing to disclose or delete.

7. Your Control

There are no accounts or sign-ups. You can remove all saved profiles at any time by deleting the app from your device.

8. Changes to This Policy

If this policy changes, the updated version will appear on this page with a new effective date. Our core promise of collecting nothing will remain.
