These pages are plain files. They set no cookies and run no analytics or advertising. Everything on them comes from this site, so nothing here can follow you anywhere else. There is no login and no form.

Cloudflare Pages serves the site and keeps ordinary server logs (IP address, time, browser) in order to deliver the pages and block abuse. GRCSAC does not use those logs to build a picture of any visitor.

Zelzi

Zelzi runs entirely on your iPhone. It has no account, no sign-in and no server, and it makes no network connections of any kind.

• The photos you turn into cards are copied into the app's own storage on the phone. The app reads only the photos you pick.
• Your cards, decks, settings and match history stay on the phone. Deleting the app deletes them.
• Zelzi sends no usage data, crash reports or telemetry to GRCSAC or to anyone else.
• While Zelzi is on TestFlight, Apple's TestFlight terms apply to the install itself, as they do for any beta app.

If a future version adds anything that uses the network, such as playing against a nearby phone, this page will say what it sends and to whom before that version ships.

The site collects nothing from anyone. Zelzi collects nothing from anyone.
