Privacy Policy — coldnumbers

1. Information We Collect

coldnumbers is designed to minimize data collection. We collect:

Automatically Collected: Standard web server logs (IP address, browser type, pages visited, timestamps) and anonymous usage analytics through Google Analytics 4 (GA4). We use cookies for analytics and to remember your theme preference. GA4 is configured with IP anonymization enabled (anonymize_ip: true), meaning your full IP address is never stored by Google.

Voluntarily Provided: If you use the Group Play feature, pool member names and contribution data are stored locally in your browser (localStorage) and are never transmitted to our servers. If you provide an email for the Group Play agreement feature, it is used solely for sending the agreement and is not stored or shared.

We Do NOT Collect: Financial information, lottery ticket numbers, Social Security numbers, payment details, or any sensitive personal data.

2. How We Use Information

Analytics data is used solely to understand site usage patterns and improve the service. We do not sell, rent, or share personal information with third parties except as required by law.

3. Cookies

We use cookies for: (a) Google Analytics 4 — to collect anonymous usage statistics (IP-anonymized); (b) Theme preferences — to remember your selected display theme; (c) Affiliate tracking — our affiliate partners may place cookies when you click affiliate links. You can disable cookies in your browser settings, though some features may not function properly. Note: if this site serves EU/EEA visitors, a consent management platform (CMP) may be required before GA4 cookies are set.

4. Third-Party Services

This site uses Google Analytics 4 (GA4) with IP anonymization enabled. GA4 collects anonymized usage data (pages viewed, actions taken, session counts) to help us improve the site. No personally identifiable information is sent to Google. Data is collected in accordance with Google's Privacy Policy. Affiliate links to Jackpocket, DraftKings, BetMGM, Kalshi, and other partners are governed by their respective privacy policies. We are not responsible for the privacy practices of third-party sites.

5. Data Security

We implement reasonable security measures to protect any information collected. However, no internet transmission is 100% secure. Group Play data stored in your browser's localStorage can be cleared by you at any time.

6. Children's Privacy

coldnumbers is intended for users aged 18 and older. We do not knowingly collect information from anyone under 18. If you believe a minor has provided information, please contact us to have it removed.
