04. EulerCoins & Rewards
EulerCoins are virtual loyalty points awarded for community participation, such as sharing roadmaps and maintaining learning streaks. EulerCoins have no monetary value, cannot be exchanged for cash, and are subject to adjustment or removal at our discretion.
05. Community Contributions
- →Users can choose to make their roadmaps "Public".
- →By making a roadmap public, you grant other users the right to "Clone" and use that roadmap structure for their own learning.
- →You agree not to share public content that is offensive, illegal, or violates intellectual property rights.
- →You agree not to use EulerFold in any way that violates YouTube's Terms of Service or Google's Developer Policies.
06. User Accounts
You must provide accurate information when creating an account. You are responsible for maintaining the security of your account and session tokens.
07. Intellectual Property
The service, including its original content, features, and functionality, is and will remain the exclusive property of EulerFold and its licensors. The roadmaps generated are for your personal, non-commercial use.
YouTube content displayed within EulerFold remains the property of the respective content creators and YouTube. EulerFold does not claim ownership over any YouTube content accessed through the YouTube API.
08. Limitation of Liability
EulerFold is provided on an "as is" basis. We make no warranties, expressed or implied, regarding the reliability, accuracy, or availability of the service.

10. AI Integrations: OpenRouter BYOK & Local Models
We are committed to providing an open, secure, and flexible learning platform. To support this, we offer distinct AI interaction modes:
- →Bring Your Own Key (OpenRouter): You may opt to use your personal OpenRouter API key for certain features. You acknowledge that you are solely responsible for the security, management, and financial costs associated with your OpenRouter account. Because EulerFold routes these requests directly from your browser without intercepting them, we cannot limit your usage or protect against API overages caused by third-party billing policies. By using this feature, you also agree to the OpenRouter Terms of Service.
- →Local AI (WebGPU): EulerFold provides the option to execute AI models directly on your device hardware via WebGPU. By using Local AI mode, you acknowledge that this process is highly resource-intensive. EulerFold is provided "as is" and we assume no liability for any hardware degradation, thermal throttling, battery drain, or system instability resulting from running local models.
- →Honest Communication: We guarantee that if you are using Local AI or BYOK, your generations are not secretly routed through our servers. We prioritize your sovereignty over your compute and data.
