Terms

Plain-language terms for reading, sharing, and using this website.

Using the site

You may use the compatibility tools, sign guides, and chart for personal reading and discussion. Do not interfere with access for other visitors or attempt to misuse site forms and routes.

Sharing and attribution

Links to public pages and shareable comparison URLs may be shared. Short excerpts may be quoted with clear attribution and a link to the relevant page.

Acceptable use

Automated activity that degrades the service, bulk republication, or presenting this site's writing as your own is not permitted. Requests that place disproportionate load on the service may be limited so the atlas remains available to other visitors.
