Privacy

RoundRoBin keeps as little as it can. This page describes exactly what that is.

What stays on your device

• The participant list you paste is processed entirely in this browser tab. It is never uploaded, and it is not saved — closing or refreshing the tab clears it.
• Your groups and exports exist only in the tab (and in your clipboard/file when you save them yourself).
• Anonymous usage counters (event names like "grouping_started" with a timestamp — never names or lists) are kept in your browser's local storage. Clearing the site's browser data removes them.

What is sent anywhere

Nothing you type. The only network traffic on this page is Cloudflare Web Analytics — a cookieless, privacy-first page-view counter from our hosting provider. It stores no cookie, collects no personal data and does not track you across sites; it produces aggregate page counts only.

No accounts, no cookies, no ads

There is no sign-in and no advertising. There is nothing stored on a server for this tool — so there is nothing server-side to delete.
