Privacy Policy

At Thai Lotto Checker, we value your privacy and believe in minimal, transparent data practices. This policy outlines how information is handled.

Data Collection Overview

Core lottery checking features operate anonymously without requiring account registration or personal profiling.

Temporary Security Logging & Anti-Abuse

To defend our services against DDoS attacks, automated exploit attempts, scraping, and brute-force key abuse, our servers temporarily record network metadata, such as client IP addresses and user agents, for rate limiting and firewall protection.

Premium Subscription & Optional Supporter Email

When a subscription key is purchased or activated, we store the cryptographic key hash, transaction identifier, active device slot tokens, activation timestamps, and remaining draw rounds. If you optionally provide an email address during checkout, it is stored securely and used solely for distributing exclusive supporter discount codes, reward giveaways, and facilitating key recovery assistance.

Data Retention & 30-Day Auto-Deletion Policy

We believe in data minimization. Device session records and inactive subscription telemetry are automatically scheduled for permanent deletion and pruned from our database once a user stops using the service for more than 30 consecutive days following subscription expiration.

Third-Party Advertising

For free-tier users, third-party advertising networks (HilltopAds) may collect non-personally identifiable browser cookies to deliver contextual advertisements. Premium subscribers enjoy zero advertisements across the entire application.

We actively enforce strict ad filtering categories to block adult, malicious, or illegal gambling content.

Partnership Ads & External Links

Clicking external partner banners or sponsored links redirects you to third-party domains governed by their own independent privacy policies. We assume no liability for third-party practices.

Local Storage & Preferences

We use browser localStorage solely for functional operations, including remembering your dark/light theme choice, active locale, pre-added tickets, and offline key caching.

Infrastructure & Service Providers

Our backend services utilize secure PostgreSQL databases (Neon, Supabase) and serverless cloud infrastructure adhering to modern encryption and security standards.
