The Lake Biwa Ride Companion is a private planning aid for a small group of friends. By using it you accept these terms.
The map and route shown in the app are a road preview, not cycling guidance. Routes are computed for cars with avoidance preferences and may still include motorways, tolls, tunnels or roads where cycling is prohibited. You are responsible for checking that every section is legal and safe to ride, and for following local traffic law and the official programmes' rules.
Checklist ticks are the group's own record. The app does not submit official checkpoint visits, does not verify GPS stamps and cannot award certificates.
Maps, routes and terrain data are provided by Google and shown under the Google Maps/Google Earth Terms of Service. Map content must not be scraped or stored outside the session in which it is displayed, apart from the narrow exceptions Google's caching rules allow. The app honours the same rule: the only Google data kept server-side is a resolved Google place ID (kept indefinitely) and place coordinates (kept at most 30 days). Photos, opening hours, ratings and photo links are shown transiently and never stored.
Distances and ascent figures are approximate. Opening hours, road closures and checkpoint availability may differ from what any map shows. The tool is provided as-is, without warranty of any kind.
The completion celebration uses a lineless, palette-recoloured adaptation of the OpenMoji maple leaf — same silhouette, outlines removed — under CC BY-SA 4.0 (the license also covers the modified SVG). The unmodified original ships alongside for provenance.
