Privacy Policy
Last updated: May 7, 2026
1. Introduction
Lucky Lines (“we,” “us,” or “our”) operates the Lucky Lines web application (the “Service”). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service. Please read this policy carefully. By accessing or using the Service, you agree to the practices described in this policy.
2. Information We Collect
Personal Information
When you create an account, we collect your email address, display name, and any profile information you voluntarily provide. If you upgrade to a paid plan, payment processing is handled securely by Stripe — we never store your full credit card number.
Usage Data
We automatically collect information about how you interact with the Service, including pages visited, features used, lineup configurations, and platform preferences. This data is used solely to improve the Service experience.
Device & Technical Data
We collect device type, browser type, operating system, IP address, and general location data (city/region level) for security and analytics purposes.
3. How We Use Your Information
- Provide, maintain, and improve the Service
- Process transactions and send related notifications
- Send you technical notices, security alerts, and support messages
- Analyze usage trends and optimize Service performance
- Personalize your experience, including model recommendations
- Detect, prevent, and address fraud and security issues
4. Data Sharing & Disclosure
We do not sell, rent, or trade your personal information. We may share data with:
- Service Providers: Supabase (authentication & database), Vercel (hosting), and Stripe (payments) — each bound by their own privacy policies
- Legal Requirements: When required by law, subpoena, or to protect our rights and safety
5. Cookies & Tracking
We use essential cookies for authentication and session management. We use Vercel Analytics for privacy-friendly, aggregated usage analytics — no personal identifiers are tracked. We do not use third-party advertising trackers.
6. Data Security
We implement industry-standard security measures including encryption in transit (TLS 1.3), encrypted authentication tokens, row-level security policies on all database tables, and regular security audits. However, no method of electronic storage is 100% secure.
7. Your Rights
You may access, update, or delete your account information at any time through the Settings page. You may request a full export of your data or account deletion by emailing us. California residents have additional rights under the CCPA, and EU residents have rights under the GDPR — contact us to exercise these rights.
8. Data Retention
We retain your personal information for as long as your account is active or as needed to provide the Service. Upon account deletion, we remove your personal data within 30 days, except where required by law or for legitimate business purposes (e.g., fraud prevention).
9. Children's Privacy
The Service is not directed to anyone under the age of 18. We do not knowingly collect personal information from children. If we discover that a child has provided us with personal information, we will delete it promptly.
10. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the “Last updated” date.
