Stock Market Hours Tracker

Last updated: May 18, 2026

In short

Stock Market Hours Tracker collects no personal data. No analytics, no ads, no tracking, no accounts. Your favorites, notifications, and settings are stored only on your device. The app works entirely offline — all exchange hours and timezone data are built in.

Overview

Stock Market Hours Tracker ("the App") is developed and operated by Deve Apps (deve.net). We respect your privacy and are committed to protecting it. This Privacy Policy explains what information the App collects, how it is used, and your rights regarding that information.

Information We Collect

The App does not collect any personal information. We do not request, store, or transmit any personally identifiable data such as your name, email address, location, contacts, photos, or device identifiers.

Local Data Storage

The App stores the following information only on your device using the operating system's secure local storage (UserDefaults on iOS, SharedPreferences on Android):

  • Your favorite (starred) exchanges
  • Notification preferences for each exchange
  • Selected language and theme preferences (light, dark, or system)
  • Home screen widget configuration (iOS)

This data never leaves your device and is automatically deleted when you uninstall the App.

Notifications

If you enable opening notifications, the App schedules local alerts on your device to inform you when a selected exchange opens.

How notifications work:

  • Alerts are scheduled and delivered entirely on your device using the operating system's local notification system (UNUserNotificationCenter on iOS, NotificationManager on Android).
  • No data is sent to any external server. We do not use push notification services like APNs or Firebase Cloud Messaging.
  • Notifications fire at most a few times per trading day, only for exchanges you explicitly star and enable.
  • We never see which exchanges you have selected — that information stays on your device.

You can disable notifications at any time from the App's settings, or revoke the system permission entirely from your device's settings.

Permissions Requested

The App may request the following permissions:

  • Notifications — only if you choose to enable opening alerts. This permission is optional; the App is fully functional without it.

The App does not request access to your location, contacts, photos, microphone, camera, or any other sensitive data.

Third-Party Services

The App does not integrate with any third-party analytics, advertising, or tracking services. All exchange hours, timezone information, and market data are bundled within the App at build time.

Data Sharing

We do not share, sell, rent, or disclose any data to any third party — because we do not collect any data in the first place. There are no data brokers, no advertising networks, no affiliates, and no business partners that receive information from this App.

Data Security

All preferences are stored locally on your device using the operating system's secure storage APIs (UserDefaults on iOS, SharedPreferences on Android). These systems are protected by the device's built-in encryption and sandboxing — only the App itself can read this data, and no other app on your device can access it.

Data Retention & Deletion

Your preferences (favorites, notification settings, theme) are retained only as long as the App is installed on your device. There are three ways to delete this data:

  • Reset within the App — unstar all exchanges and disable all notifications.
  • Clear app data (Android) — from your device's app settings.
  • Uninstall the App — all locally stored data is permanently deleted automatically.

Since we never receive your data, there is nothing for us to delete from any server.

Internet Access

The App functions entirely offline. No internet connection is required to use it, and the App does not transmit any data over the network. Tapping a link inside the App (such as a developer website link) will open your default browser, at which point your browser's own privacy policy applies.

Children's Privacy

The App is suitable for all ages and is appropriate for general audiences. We do not knowingly collect personal information from children under the age of 13 (or the equivalent minimum age in your jurisdiction). Since no personal data is collected from any user at all, no special provisions or parental consent mechanisms are required.

If you believe that a child has somehow provided us with personal information through the App, please contact us at app@deve.net and we will investigate and take appropriate action.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, new App features, or legal requirements. Any changes will be posted on this page with an updated "Last updated" date at the top. If we make material changes that affect how we handle your data, we will provide a more prominent notice — such as a notification within the App on next launch. We encourage you to review this policy periodically.
