Privacy Policy

Last Updated: January 2026

Your privacy is important to us. This policy explains how Jadual Waktu handles your data.

TL;DR - The Short Version

  • ✅ Your timetable data stays on YOUR device (localStorage)
  • ✅ We don't collect, store, or share your personal information
  • ✅ We use privacy-focused analytics (Umami) - no tracking cookies
  • ✅ No sign-up required, no accounts, no data sent to servers
  • ✅ You own your data - export it anytime

Data Storage & Ownership

Local Storage Only

All your timetable data (subjects, schedules, settings) is stored exclusively in your browser's localStorage. This means:

  • Data never leaves your device
  • We don't have access to your timetables
  • No servers store your personal schedules
  • You maintain complete ownership of your data

Your Control

You can:

  • Export all your data at any time using the Export feature
  • Delete all data by clearing your browser's localStorage
  • Transfer data between devices using Import/Export

Analytics & Tracking

Privacy-Focused Analytics

We use Umami Analytics, a privacy-focused, GDPR-compliant analytics service. Umami helps us understand how people use the app without invading your privacy.

What We Collect

  • Page views (which pages you visit)
  • Basic device information (browser type, screen size, operating system)
  • General location (country/region level only, not precise location)
  • Referral source (where you came from)

What We DON'T Collect

  • ❌ No personally identifiable information (PII)
  • ❌ No cookies or tracking pixels
  • ❌ No cross-site tracking
  • ❌ No IP address storage
  • ❌ No timetable content or subject names

Note: Umami analytics are completely anonymous and aggregated. We cannot identify individual users or their activities.

Third-Party Services

Jadual Waktu uses the following third-party services:

Data Security

Since your data is stored locally on your device:

  • Your data security depends on your device's security
  • We recommend regular backups using the Export feature
  • Clearing browser data will permanently delete your timetables
  • Private/incognito browsing may not persist data between sessions

Children's Privacy

Jadual Waktu is designed for students of all ages. Since we don't collect personal information, no special parental consent is required. The app is safe for children to use.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.
