Local-first progress: browser and Android WebView progress stays on this device unless the app sends a device identifier to the D1-backed API. Use export for review or reset when testing.
Game Progress
Track practice without turning it into surveillance.
This page reads local browser or app WebView progress first, then can use D1-backed progress when an app/device identifier is available. It is designed for the future native Android Progress tab.
