PRIVACY_POLICY: ODD_NUMBER_OUT

Odd Number Out is a number-pattern puzzle with a three-lives mechanic. This document explains how the program handles player data.

// Local execution only

Number generation, rule selection, and answer validation all run client-side in your browser. No grid, rule, or answer is ever sent to a remote server.

// Runtime session variables

• Current difficulty level and score;
• Remaining lives counter (3 to 0);
• The active rule and the nine generated numbers for the round.

These variables exist only in memory for the open tab and are discarded on refresh or close — no persistent storage is used.

// Typeface delivery

The JetBrains Mono font is fetched from Google Fonts at page load. This is a standard font-delivery request and does not collect personal data.

// No login required

No account, username, or email is requested at any point — the program runs fully anonymously.

// Revision log

This document may be revised; the date at the top always reflects the current version.
