Editor's Overview

KyuubiMask - Privacy First is a notification application developed by soraiyu, packaged as a single Android APK of version 1.7 weighing in at 2.46 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 2.46 MB, so it installs quickly even on modest connections.
  3. This build is signed by "soraiyu" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

KyuubiMask is designed to keep your notification content away from prying eyes. It replaces notification text as quickly as possible, making it much harder for others to read what you received—even if they're looking right at your screen. Notification content is never displayed or saved by this app.

KyuubiMask is a privacy-first notification masking tool that protects your sensitive information during screen sharing, presentations, or when your screen is visible to others.

🔒 PRIVACY FIRST
• No internet permission - works completely offline
• No data collection or storage
• No tracking, analytics, or ads
• Notification content is never logged or saved
• Open source with Apache 2.0 license

✨ FEATURES
• Masks notifications from any app you choose with generic text
• Tapping a masked notification opens the original app directly, without revealing any content
• Built-in presets for Slack, Discord, WhatsApp, and LINE
• Per-app toggle to choose which apps to mask
• Quick Settings tile for one-tap masking toggle
• Simple on/off toggle to enable or disable the service

📱 SUPPORTED APPS
KyuubiMask works with any installed app — select additional targets via the "Add custom apps…" button in Settings. Slack, Discord, WhatsApp, and LINE are available as built-in presets.

🎯 PERFECT FOR
• Screen sharing during video calls
• Live presentations and demos
• Recording tutorials or videos
• Working in public spaces
• Protecting your privacy

💡 HOW IT WORKS
When enabled, KyuubiMask replaces notification content from supported apps with generic text like "New notification", hiding sensitive information while still allowing you to see that you received a notification.

📖 WANT TO CHECK A NOTIFICATION LATER?
This app never saves notification content. If you want to review what you received, on supported devices (Android 11+), you can use Android's built-in Notification History if available and enabled (Settings → Notifications → Notification History).
