Privacy by design • Transparent by default

Health first. Privacy always.

This policy explains what data we collect on the FASTNAT website and simulator, how we use it, how long we keep it, and your choices. We keep data collection minimal and prefer local-only storage wherever possible.

Last updated: November 6, 2025

1) Overview

FASTNAT is a public simulation and information site. It does not provide medical or financial services and the on-site mining is a simulation. We prioritize privacy by default and minimize personal data collection. When feasible, we keep information on your device using client-side storage (e.g., localStorage).

2) Data We Collect

A. Data you provide

  • Contact messages: name, email, and the content you submit via email or form.
  • Stories / comments (Share Your Story page): the text you post and basic interaction metadata. Anti-spam may require a CAPTCHA.

B. Data collected automatically (minimal)

  • Technical logs (server): IP, user-agent, and timestamps for basic security and reliability.
  • PWA & local storage (client): preferences, simulation state, and cached assets stored on your device.

C. Optional analytics

If enabled, we may use privacy-respecting analytics (e.g., GA4 or Plausible) to measure usage trends without directly identifying you. You can opt out via your browser’s Do Not Track setting and/or cookie choices.

3) How We Use Data

  • Operate and improve the website and simulator.
  • Respond to inquiries and moderate user-generated content.
  • Detect, prevent, and investigate security incidents and abuse.
  • Comply with legal obligations where applicable.

4) Cookies & Local Storage

  • Essential: session or preference cookies and the Service Worker cache for PWA/offline.
  • Local storage: simulation state (e.g., elapsed time, UI settings) kept on your device.
  • Analytics (optional): only if you consent or if strictly necessary for aggregated metrics.

You can clear cookies/local storage anytime in your browser settings.

5) Data Sharing

  • We do not sell personal data.
  • Service providers may process limited data to operate infrastructure, security, or analytics.
  • We may disclose information if required by law or to protect users and the service.

6) Data Retention

  • Server logs: short, bounded periods for reliability and security.
  • Contact emails and reports: retained as long as needed to respond and for compliance.
  • Local storage: remains on your device until you clear it.

7) Your Rights & Choices

  • Access, update, or delete content you posted where features permit.
  • Opt out of optional analytics and marketing communications.
  • Request deletion of contact messages or reports you sent us.

Rights may vary by jurisdiction. We will make good-faith efforts to honor valid requests.

8) Children’s Privacy

This website is not intended for children under 13. We do not knowingly collect personal data from children.

9) International Use

The site may be accessed globally. If you use it from other regions, your data may be processed where our infrastructure or providers operate. We take reasonable steps to protect information consistent with this policy.

10) Changes to This Policy

We may update this policy from time to time. Material changes will be reflected by updating the “Last updated” date above.
