Terms of Service
These terms govern your use of Trazo (https://trazo.runvia.app, the “Service”), operated by Junlab (“we”, “us”). By using the Service you agree to these terms.
Effective date: November 9, 2026. A Korean version is available at /terms/; if the versions differ, the Korean version prevails to the extent permitted by law.
1. The Service
Trazo lets you draw running and cycling routes on a map, check distance, elevation and gradient, save, share and export routes, use community features, and connect your routes to AI assistants such as ChatGPT and Claude through an MCP server. The Service is free. We may add, change or discontinue features.
2. Accounts
Saving routes and community features require signing in with Google. You are responsible for your account and for any AI assistants or other services you connect to it. You must be at least 14 years old to use the Service.
3. Your content
You keep the rights to the routes, descriptions, waypoints, comments and nickname you create. For content you set to “link sharing” or “public”, you allow us to display it within the Service (including search results, link previews and the course map) and allow other users to save or download it. This permission ends for future use when you make the content private or delete it.
4. Prohibited conduct
- Infringing others’ rights or posting illegal or harmful content
- Impersonating or harassing other users
- Accessing the Service or other accounts without authorization, or disrupting the Service with excessive automated requests
- Knowingly sharing routes that lead people to dangerous or prohibited areas
We may hide or remove content that violates these rules and restrict the related accounts.
5. Route information and safety
Routing results, distance, elevation, gradient, estimated times, routes shared by other users, and recommendations an AI assistant makes from Service data are for reference only. Always check actual road conditions, construction, access restrictions, weather, traffic laws and your own health, and exercise safely. We do not guarantee the accuracy of route information or its fitness for any particular purpose.
6. AI assistants and third-party services
If you connect ChatGPT (OpenAI), Claude (Anthropic), Garmin Connect or other services, they exchange data with the Service within the scope you authorize. Your use of those services, and the answers or results they produce, are governed by their own terms and policies. You can disconnect at any time in the Connection Center.
7. Limitation of liability
Except in cases of our intent or gross negligence, we are not liable for damages arising from your use of the Service or from following route information or AI recommendations, or for interruptions caused by events beyond our control, including outages of third-party services. Nothing in these terms limits liability that cannot be limited under applicable law.
8. Changes and governing law
We will announce changes on this page before they take effect. These terms are governed by the laws of the Republic of Korea.
