Privacy Policy
Effective March 4, 2026
Golf Data Viz is built by a golfer, for golfers. We collect only what we need to show you where you gain and lose strokes — nothing more.
What We Collect
When you enter a round, we store only the stats you provide:
- Score, course rating, and slope rating
- Fairways hit, greens in regulation, and total putts
- Penalty strokes and scoring distribution (birdies, pars, bogeys, etc.)
- Course name and handicap bracket
What We Don't Collect
- No account required — you can use the SG Benchmarker without signing up
- No personally identifying information — we don't ask for your name, email, or location
- No GPS or shot-level data — we work from aggregate round stats only
How Data Is Stored
Round data is stored in a Supabase-hosted PostgreSQL database with row-level security enabled. Each user's data is isolated at the database level — no user can access another user's rounds.
Sharing
Sharing is opt-in. If you share a results link, it contains encoded round stats needed to recreate the chart. We do not sell, rent, or share your data with third parties.
Analytics & Error Tracking
- We use Vercel Analytics and optional GA4 for aggregate usage signals.
- We do not send round stat fields (score, fairways, GIR, putts, penalties, category counts) to analytics platforms.
- Sentry is used for error diagnostics.
Questions?
If you have questions about how we handle data, open an issue on GitHub or reach out on r/golf.
