One is a page counter. The other is Cloudflare’s bot check, which only loads when you open the critique form. There are no cookies, no accounts and no email sign-up. Your answers to the Your Reality questions stay in your browser. If you send a critique, we store what you submit: the text, the node, the choices you made if you add them, and the time. One reader sees it. We don’t store your IP address. Cloudflare Web Analytics a cookieless beacon that counts page views in total.

No kind of reader ranks above another. Every page, file and dataset is open to everyone on the same terms. Nothing is held back or changed depending on who or what is reading. The one exception is the critique form. It runs an automated spam check that may turn away automated senders. A reader it stops can still quote and cite anything here. ## Reuse, by any reader The site’s writing and data are licensed [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/).
