Privacy, accessibility and corrections.

Privacy

This website does not use cookies, advertising or analytics tracking, and it does not collect personal information unless you choose to email NCI. Fonts and images are served from this site rather than third-party services.

The site is hosted on GitHub Pages. GitHub may log basic technical information, such as IP addresses, for security purposes under its own privacy statement.

If you email NCI, your message is used to respond to you. If you subscribe to NCI updates, your email address is used only to send those updates, and you can unsubscribe at any time. NCI does not sell email addresses or share them for marketing. If NCI uses an email or online giving service, that service processes your information under its own privacy terms.

Accessibility

NCI aims to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at level AA. Pages are tested with automated accessibility checks, keyboard navigation, screen-reader landmarks and 200% text size on phones and desktops.

If any part of the site is difficult to use, email donavan@nciresearch.org with the page address and what happened. NCI can also provide a brief in another format.

Corrections

If you find an error, email the page address and, where possible, the source that shows the correct information. Material corrections are made on the page and reflected in its updated date.
