Terms of Service

1. Acceptance of Terms

Welcome to Rule9 (rule9.bike). By accessing or using our application, you agree to be bound by these Terms of Service. Rule9 provides route weather analysis and AI-based coaching suggestions based on third-party weather data (Open-Meteo) and routing platforms (Strava).

2. Acceptable Use

• We do not guarantee the absolute accuracy of weather forecasts or AI suggestions. Cycling inherently carries risks, and you assume full responsibility for your own safety on the road.
• You must not misuse our services or attempt to access them using a method other than the interface and instructions that we provide.
• We reserve the right to suspend or terminate your access to the service if you violate these terms or abuse the API rate limits.

3. Intellectual Property

The Rule9 name, logo, application design (UI/UX), architecture, and underlying source code are the exclusive property of the creator of Rule9. All rights are strictly reserved.

You can disconnect Strava and delete app-held data at any time via the "Disconnect Strava" button in the app, or via Strava App Settings. See our Privacy Policy for full details.
