Privacy Policy

Short version: there are no accounts, no profiles, and no database of your golf data. You give the tool some numbers (and sometimes a screenshot), it does the math, and you get a result. Here's exactly what happens to it.

What you give us

• Things you type: scores, handicap indexes, course and tee selections, and any name you choose to enter for a "defendant."
• Screenshots you choose to upload (score histories or a tournament results sheet).

We never ask for your identity, and you don't need an account.

Where it goes

• The calculations happen in your browser. We don't receive your scores or verdicts.
• Shared calculation links: if you choose “Copy result link,” the calculator inputs are encoded after the # in the link. That fragment is not sent in the web request, and we remove it from the recipient's address bar before analytics loads. Anyone you send the link to can still see the included course and round inputs and recompute the result.
• Course search: the course name you type is sent to GolfCourseAPI to look up ratings and slope.
• Screenshots: when you upload, the image is sent to our server and forwarded to Anthropic (Claude) to read the numbers off it. We do not store the screenshots — they're processed for that single request and discarded on our end. Anthropic processes them under its privacy policy.
• Bot check: uploading triggers Cloudflare Turnstile to confirm you're human. Cloudflare processes your IP and challenge data and may set a functional/security cookie for this.

The verdict card

If you create a shareable card, it's generated in your browser. We don't post it anywhere — sharing it is entirely your choice, and you can redact the name first. Calculator cards can include the same private-fragment calculation link described above.

Logs & infrastructure

The site and its functions run on Vercel, fronted by Cloudflare. Like any website, these keep standard request logs (such as IP address, timestamp, and the page requested) to run the service and prevent abuse, per their own policies.

Analytics & cookies

We use Cloudflare Web Analytics, a privacy-first, cookieless tool, to count visits and page views. It doesn't use cookies, fingerprint you, or track you across other sites.

We also use Google Analytics to understand visits, pages viewed, referral sources, completed analysis tools, and general usage over time. Google Analytics loads automatically and sets first-party analytics cookies (including _ga) that distinguish browsers and sessions. Shared calculation fragments are removed before Google Analytics loads, so those inputs are not included in its page-location data. Campaign labels in links (such as source, campaign, and content labels) may be kept for the current browser tab and attached to anonymous product-event counts; we do not retain advertising click IDs or user identifiers in that event stream. We keep Google advertising storage, advertising user data, and ad personalization disabled; we do not use these analytics cookies for advertising. Google handles analytics data under its privacy policy.

You can block or delete analytics cookies through your browser settings. Cloudflare or Turnstile may still set functional/security cookies so the site works and stays protected.

What we don't do

• We don't store your scores, handicaps, names, or screenshots.
• We don't sell or share your data with advertisers.
• We don't publish anyone's name or any result. Output is shown only to you, in your browser.

Children

This site isn't directed to children under 13, and we don't knowingly collect their information.

Changes

We may update this policy; the date above reflects the latest version.
