These terms apply to EVE Cookbook: the website at evecookbook.com, its public API and its Discord bot (together, the "Service"). EVE Cookbook is a free, non-commercial fan tool for EVE Online, run by Celengan Babi (an EVE Online character), "we" or "us". By using the Service you agree to these terms. If you don't agree, please don't use it.

The Service

EVE Cookbook calculates the materials, job costs and build steps for manufacturing and reactions in EVE Online, using EVE Online's static data and market prices. The Service is free and needs no account. We may change, pause or stop any part of it at any time, for example for maintenance or when game data changes.

Calculations are estimates

Results are estimates for planning, not guarantees. Market prices are the best Jita buy and sell orders from EVE Online's API, refreshed about once an hour, and can differ from what you actually pay or earn. Game data, cost indices and bonuses change with EVE Online patches and may be out of date until we update them, and some mechanics are simplified. Check important numbers in game before you commit ISK to a build.

Using the API and the Discord bot

You're welcome to use the API and the Discord bot in your own tools and spreadsheets, as long as you:

• stay within the rate limits: currently 20 requests per 5 seconds per IP address and up to 20 blueprints per request (use the bulk format for more);
• don't try to overload, disrupt or get around the limits or security of the Service;
• don't present the Service or its results as your own product or as official EVE Online data.

We may limit or block access that harms the Service or other users. The API is documented at evecookbook.com/api; its format may change, and we'll try to announce breaking changes on our Discord server first.

Logging in with EVE Online

Logging in is optional and uses EVE Online's official single sign-on (EVE SSO); we never see your EVE account password. You can remove linked characters in Config → Characters or revoke access on EVE Online's authorized applications page. What we store and why is described in the privacy policy.

EVE Online and Fenris Creations

EVE Online and the EVE logo are trademarks of Fenris Creations (previously CCP Games). EVE Cookbook is a fan project that is not endorsed by or affiliated with Fenris Creations or CCP Games. Using the Service doesn't change your agreements with them, including the EVE Online End User License Agreement.

No warranty and limitation of liability

The Service is provided "as is", without warranty of any kind. We don't promise that it is always available, error-free or that its results are accurate. To the extent the law allows, we are not liable for any loss arising from using the Service, including lost ISK, in-game assets or time. Nothing in these terms limits liability that can't be limited by law.

Links to other sites

The Service links to other sites, such as EVE Online, Discord and other community tools. We aren't responsible for their content or how they handle your data; their own terms and policies apply.

Changes and contact

We may update these terms, for example when the Service changes. The date at the top shows the latest version, and continuing to use the Service after a change means you accept it. Questions? Contact us on our Discord server or send an EVE mail to Celengan Babi.
