Terms of use

Last updated 26 October 2026

Information, not advice

The site gives estimates for research and discussion. They are uncertain, depend on value judgments you can change, and can be wrong. Nothing here is financial, legal, tax or investment advice, or a recommendation to give to or not to give to any organisation. Decide for yourself, and check the original sources.

No endorsement

Models based on GiveWell's or Animal Charity Evaluators' work are our re-implementations. Those organisations, and the charities listed, have not reviewed or endorsed this site. Names and trademarks belong to their owners.

Reusing our work

• Code: MIT licence.
• Models derived from GiveWell's analyses: CC BY-NC-SA 3.0 US, as GiveWell licenses its own work. Credit GiveWell and this site, don't use them commercially, and share changes under the same licence.
• Models derived from Animal Charity Evaluators' analyses: check ACE's terms before reusing them.
• Our own write-ups and models: you may quote and reuse them with a link back to the page.

Availability and liability

The site is provided as it is, without warranty, and may change or go offline at any time. To the extent the law allows, we are not liable for losses from using it or relying on its estimates. Nothing in these terms limits liability that cannot be limited under Dutch law.

Law

These terms are governed by Dutch law. Questions: hello@charityevals.org.
