About KyuubiMask - Privacy First
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.
