Privacy Policy

Last updated: March 13, 2026

Overview

Ztime.now is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our world clock and time zone tools.

Information We Do Not Collect

Ztime.now is designed with privacy as a priority. We do not:

  • Collect personal information (name, email, address)
  • Use tracking cookies for advertising
  • Store your location data on our servers
  • Share data with third parties
  • Require account registration
  • Fingerprint your browser or device

Privacy-First Analytics

We collect minimal, aggregated usage data to improve Ztime.now. This analytics system:

  • Respects Do Not Track: If your browser sends the DNT header, we don't collect any analytics
  • No PII: We never collect names, emails, IP addresses, or any personally identifiable information
  • No Cookies: We use sessionStorage only (cleared when you close the browser)
  • Random Session IDs: Session identifiers are random strings, not linked to you
  • 90-day Retention: Analytics data is automatically deleted after 90 days

Data we collect includes:

  • Feature usage (e.g., "Meeting Planner opened", "Time Converter used")
  • Page views (which pages are visited)
  • Theme preferences (light/dark mode usage)

Local Storage

Your selected cities and preferences are stored locally in your browser using localStorage. This data never leaves your device and is used solely to remember your settings between visits. You can clear this data at any time by clearing your browser cache or using the "Reset All" button in the app.

Advertising

We may display advertisements through Google AdSense. Google may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ad Settings.

Time Synchronization

To ensure accuracy, Ztime.now connects to public time servers (NTP) to calibrate your device clock. These requests do not transmit any personal information.

Your Rights

You can:

  • Enable "Do Not Track" in your browser to opt out of analytics
  • Clear localStorage data at any time via browser settings
  • Use Ztime.now in incognito/private mode for a completely fresh session

We may update this Privacy Policy periodically. Changes will be posted on this page with an updated date. Significant changes will be announced via a notice in the application.
