Privacy Policy

Last updated: April 2026

1. Introduction

Block Lottos ("we", "our", "us") operates the Block Lottos website and smart contracts. This Privacy Policy explains how we collect, use, and protect information when you use our services.

2. Information We Collect

Blockchain Data: When you purchase a lottery ticket or interact with our smart contracts, your wallet address and transaction details are recorded on the Polygon blockchain. This data is public and immutable by nature of blockchain technology.

Contact Form: When you use our contact form, we collect your name, email address, and message content for the purpose of responding to your inquiry.

Advertising Data: If you use our advertising platform, we collect your wallet address, uploaded banner images, destination URLs, payment transaction hashes, and selected banner size and duration preferences.

Cookies: We use cookies to enhance your experience on our website. You can manage cookies through your browser settings.

Analytics: We use Google Analytics (gtag.js) to collect anonymised usage data such as page views, visit duration, referral sources, and general geographic region. This helps us understand how visitors use our site and improve the experience. Google Analytics may set its own cookies. For more information, see Google's Privacy Policy.

Bot Protection: We use Google reCAPTCHA Enterprise on our contact form to prevent spam and abuse. reCAPTCHA may collect hardware and software information, such as device and application data, and send it to Google for analysis. Use of reCAPTCHA is subject to Google's Privacy Policy and Terms of Service.

3. How We Use Information

We use information to operate the Block Lottos lottery, process advertising submissions, respond to support inquiries, and improve the website experience through analytics. We do not sell, rent, or share personal information with third parties, except as described in this policy (e.g., Google Analytics and reCAPTCHA as outlined above).

4. Blockchain Transparency

All lottery transactions occur on the public Polygon blockchain. This means your wallet address, ticket purchases, and prize claims are publicly visible to anyone. This is a fundamental property of blockchain technology and is what makes Block Lottos transparent.

5. Data Retention

Blockchain data is permanent and cannot be deleted. Contact form submissions are retained for up to 12 months and then deleted.

6. Your Rights

You have the right to request deletion of any personal data we hold (excluding immutable blockchain records). Contact us at the address on our Contact page.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
