Privacy Policy

We collect the minimum needed to make the site work — and nothing else.

Last updated · May 2026

What we collect

  • Location (optional, on-device). The GPS and Weather generation modes read your approximate location from your browser. The value is used to seed the random number generator and is never sent to our servers.
  • Saved numbers (on-device). If you save number sets, they are stored in your browser's localStorage. We never see them.
  • Anonymous analytics. We use Google Analytics 4 / Google Tag Manager to count page views and understand which features are used. No personally identifying information is collected.

What we don't collect

  • We do not collect your name, email, address, or phone number.
  • We do not run third-party advertising or affiliate tracking.
  • We do not sell, rent, or share any data with third parties for marketing.
  • We do not require account creation or sign-in.

Cookies & local storage

We use browser localStorage to remember your saved number sets and preferences. Google Analytics sets its own first-party cookies for measurement. You can clear both at any time from your browser settings; the site continues to work without them.

Third-party services

  • ANU Quantum RNG (qrng.anu.edu.au) — supplies quantum entropy when generating numbers. Each request sends only the byte count we need; no user data is shared.
  • NY State Open Data (data.ny.gov) — public source of Powerball and Mega Millions historical draws.
  • Google Analytics 4 / Google Tag Manager — anonymous usage measurement.
  • Cloudflare Pages — hosts and serves the site; standard server logs (IP address, timestamp, user agent) are retained per Cloudflare's policy.

Children

Lotto Laboratory is intended for users 18 years of age or older. We do not knowingly collect data from anyone under 18.

Your rights

We don't hold personal data, so most rights requests (deletion, portability, correction) are a no-op. If you have questions, contact us anyway — burademirung@gmail.com.

Changes

If we change this policy, we update the "Last updated" date at the top. Material changes will be highlighted on the homepage for at least 30 days.
