Crowfly.golf – Zero-backend GPS round tracking (localStorage)

Crowfly.golf is a zero-backend, single-HTML-file GPS golf round tracker that stores all shot data locally in the browser, requiring no account or server. It is designed for golfers who want a simple, private way to log shots, view distance markers, and export rounds as CSV without any login friction. Its interesting because it deliberately rejects modern SaaS norms—planning to add mandatory login and AI club recommendations—making it a provocative commentary on data ownership and feature creep in sports tech.
