Your predictions. Your privacy.

Nostradamus is a small pilot game. You can play without giving us your name or email.

What we save

An anonymous browser identity connects your predictions, scores and streak. We record simple gameplay activity, such as visits, submissions and shares, to learn whether players return. Clearing browser storage or changing devices can start a new history.

Email is optional

If you opt in, we save your email and when you agreed to reminders. We use it only for Nostradamus challenge reminders. Every reminder includes a no-login unsubscribe link. We do not sell or share your email for advertising.

How the app works

The local preview stores data on this computer. A configured hosted pilot uses Supabase for authentication and storage, and Resend to deliver emails. Essential browser storage keeps your session and draft order; we do not use advertising cookies.

Your choices

Skip the email prompt, unsubscribe from any reminder, or clear this site's browser data to start a new anonymous history. Clearing browser data does not delete results already stored by the pilot. For removal of stored records, contact the person who invited you to the pilot.
