Privacy Policy

1. Client-Side Browser Storage (`localStorage`)

LongUntil does not use server-side tracking sessions or database user records. We utilize standard browser localStorage exclusively on your device for user experience preferences:

• Theme Preference: Storing your selection of Dark or Light mode.
• Audio Alarm & Volume: Retaining local audio alarm enablement states so alarms chime reliably on zero-hour triggers.

This data never leaves your personal browser hardware and can be cleared at any time via your browser settings.

2. Cloudflare CDN & Analytics Disclosures

To ensure high security, DDoS mitigation, and global edge delivery, LongUntil routes traffic through Cloudflare, Inc. and utilizes aggregated performance metrics:

• Cloudflare Web Analytics & CDN: Collects non-invasive, privacy-first aggregated metrics (e.g., page views, country-level aggregate counts, HTTP status codes) without using client cookies or fingerprinting.
• Google Analytics 4 (GA4): Collects anonymized usage trends to help us understand popular countdown anchors. IP masking/anonymization is enabled to ensure individual IP addresses are never logged or stored.

3. Google AdSense & Advertising Cookies

LongUntil is monetized exclusively through Google AdSense. Google, as a third-party vendor, uses cookies to serve contextual and interest-based advertisements on our website:

• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to LongUntil and other sites across the internet.

4. International Data Rights (GDPR, UK-GDPR & CCPA/CPRA)

Depending on your jurisdiction (including the European Economic Area, United Kingdom, and State of California), you possess statutory rights regarding personal data:

• Right to Know & Access: Because LongUntil collects zero personal profiles, account registries, or identifiable databases, we store no personal records to disclose.

• Do Not Sell My Personal Information: We do not sell, rent, or trade personal data to third parties under any circumstances.

5. Protection of Minors (COPPA Compliance)
