• Local storage: We may use your browser’s local storage to save UI preferences (such as selected filters or frequency toggles). This data never leaves your device.
• Server logs: Our hosting provider (Vercel) collects standard server logs, which may include IP addresses, browser type, referring URLs, and timestamps. These logs are used solely for operational purposes.
• Analytics: We may collect anonymous usage data such as page views, feature interactions, and session duration using randomly-assigned identifiers. No personally identifiable information is collected.

2. How We Use Information

• Server logs support site operations, performance monitoring, and security.
• Analytics data helps us understand usage patterns and improve the user experience.
• We do not sell personal information.

3. Third-Party Services
