Platform Code Availability

Any future public repository release, including the software license that applies to that release, will be announced separately.

If you want to collaborate before a public repository release, contact the maintainers directly. [email protected].

Branding and Names

Unless stated otherwise in writing, no software, content, or data license on this website grants rights to use the Energy Arena name, logo, or domain names in a way that suggests affiliation with the official hosted instance.

This includes the Energy Arena name, the official domains, and any presentation that could imply endorsement, partnership, or operation by the maintainers of the official hosted instance.

• Store and evaluate your submissions against ground truth data

• Use submissions for research purposes and platform improvement

Pseudonymous Participation

You can maintain privacy by:

Forecasts are associated with your chosen username. If you use a pseudonym instead of your real name, your submissions remain anonymous to the public while still being evaluated and shown in leaderboard metrics.

Energy Arena collects minimal personal information:

• Registration: Email address, username, and optional affiliation

• Usage: API access logs for rate limiting and abuse prevention

We do not sell your personal information. We may share limited personal information with service providers that help operate the official hosted instance, currently bwCloud for hosting and Mailgun for transactional email delivery. Data is used for platform operation, security, and the public benchmarking workflow described in the Privacy Policy.

For details, see the Privacy Policy.
