Terms of Service
Last updated: March 23, 2026
1. Acceptance of Terms
By accessing and using Energy Arena ("the Platform"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Platform.
These Terms govern your use of the official Energy Arena website and API operated by the platform maintainers. They do not modify the open-source license terms that apply to the source code.
2. Platform Purpose
Energy Arena is an open-source research platform for benchmarking energy forecasting models. The official hosted instance is provided free of charge for research and educational purposes. If you want to use the official hosted instance for commercial purposes, please contact us. The source code is released under the MIT License and can be used under that license in self-hosted deployments.
3. User Accounts and API Keys
3.1 Registration: You must provide a valid email address for account verification. Your chosen username and optional affiliation are displayed publicly on leaderboards alongside your forecasts. You may use a pseudonymous username to maintain anonymity (e.g., "forecaster123").
3.2 API Keys: You are responsible for maintaining the confidentiality of your API keys. Sharing API keys is prohibited. All submissions made with your API key are attributed to your account.
3.3 Account Security: You are responsible for all activities under your account. Notify us immediately of any unauthorized use.
3.4 Pseudonymous Participation: You may participate anonymously by choosing a pseudonymous username and omitting affiliation. Your email address remains private.
4. Forecast Submissions and Data Rights
4.1 Ownership: You retain all intellectual property rights to your forecast models and methods.
4.2 Public Disclosure: Forecast submissions participate in public rankings under your chosen username.
- Aggregated metrics (MAE, RMSE, WIS, CRPS, etc.) are shown on public leaderboards
- Forecast trajectories are displayed publicly only when you set forecast visibility to open
- If you set forecast visibility to closed, only aggregated metrics remain public
- All submissions are associated with your chosen username and optional affiliation
- Open forecasts can be viewed and analyzed by other users
4.3 License Grant: By submitting forecasts, you grant Energy Arena a non-exclusive, worldwide, royalty-free, perpetual license to:
- Store and process your submissions for scoring
- Publicly display open forecasts on leaderboards, charts, and visualizations according to your selected forecast visibility
- Use your submissions (aggregated or individual) for research and platform improvement consistent with your selected forecast visibility and the Privacy Policy
- Publish statistical analyses and visualizations of platform activity
- Share aggregated results and open forecasts with researchers for academic purposes
4.4 Data Deletion: You can delete your account directly from the dashboard. This removes your participant-linked data from the primary platform database.
- Your profile, API keys, challenge profiles, submissions, scores, and leaderboard rows are deleted from the primary database
- Already exported research outputs, downloaded datasets, publications, backups, and third-party archives may still persist outside the live platform database
- Deletion affects the official hosted instance and does not automatically remove copied data from external systems
Important: Only submit forecasts you are comfortable making publicly available. Do not submit proprietary or confidential forecasting methods as raw submission data.
5. Acceptable Use
You agree NOT to:
- Submit fraudulent, manipulated, or intentionally misleading forecasts
- Attempt to reverse-engineer ground truth data before official release
- Abuse the API with excessive requests (rate limits apply)
- Harass or impersonate other participants
- Violate any applicable laws or regulations
6. Ground Truth Data
Public browser-visible realized-value charts are based on Bundesnetzagentur | SMARD.de data under CC BY 4.0. Internal evaluation processing may additionally use ENTSO-E data under the applicable ENTSO-E terms. All external data is provided "as is" without warranties.
7. Leaderboards and Rankings
7.1 Public Display: Leaderboard rankings are public and associated with your chosen username.
7.2 No Guarantees: Rankings are for informational and research purposes only. We do not guarantee accuracy, availability, or continuity of the service.

9. Disclaimer of Warranties
THE PLATFORM IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. We do not guarantee uninterrupted service, accuracy of scores, or fitness for any particular purpose.
10. Limitation of Liability
To the maximum extent permitted by law, Energy Arena and its operators shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Platform.
11. Changes to Terms
We reserve the right to modify these terms at any time. Continued use of the Platform after changes constitutes acceptance of the new terms. Material changes will be announced via email to registered users.
12. Termination
We reserve the right to suspend or terminate accounts that violate these terms or abuse the Platform.
