ZeengoCorp Innovations Launches NoteVault v2.9.2 with Advanced AES-256-GCM On-Device Encryption

FOR IMMEDIATE RELEASE

Gurugram Venture Studio Upgrades Flagship Consumer Privacy App with Hardware-Backed Cryptography and Zero-Knowledge Architecture

GURUGRAM, HARYANA, INDIA — June 4, 2026 — ZeengoCorp Innovations, a leading venture studio and operating holding company headquartered in Gurugram, India, today announced the official launch of NoteVault version 2.9.2. This major release introduces authenticated, local-only AES-256-GCM encryption and a full Material 3 design overhaul to its popular disguised privacy app for Android.

NoteVault solves a major challenge in consumer mobile security: how to hide private photos, videos, and documents on a shared device without drawing attention. The app appears and behaves exactly like a functional, modern notepad app, allowing users to write notes and manage lists. However, typing a secret trigger word into the search bar unlocks a secure, encrypted vault for sensitive media and documents.

"Most privacy vaults look like vaults, which defeats the purpose because it alerts anyone holding the unlocked device that there is hidden content," said Abhishek Rajput, Founder and CEO of ZeengoCorp Innovations. "With NoteVault, we've built a real, useful notepad that conceals a zero-knowledge cryptographical vault. If someone opens your phone, they see only notes. Your private files remain completely invisible and mathematically secure."

Key Technological Enhancements in v2.9.2:

• Authenticated On-Device Encryption: Every file imported into the vault is encrypted locally using the AES-256-GCM standard. Data encryption keys are generated randomly on-device and never leave the client.
• PBKDF2 Key Derivation: User passwords are secure against brute-force attacks using the industry-standard PBKDF2 function, derived using HMAC-SHA-256 and localized salts.
• 100% Zero-Knowledge & Offline Architecture: NoteVault operates completely offline. No user data, passwords, or recovery codes are ever transmitted to or stored on external servers, ensuring absolute user data sovereignty.
• Hardware-Backed Cryptography: The application integrates with the Android Keystore System to store derived keys securely, utilizing Trusted Execution Environments (TEE) on compatible hardware.
• Material 3 Design Overhaul: A modern, sleek UI featuring dynamic colors, smooth transitions, and absolute dark mode.
• Intruder Detection Logs: Capture details (timestamp and unlock attempt history) of unauthorized individuals attempting to guess the vault password.

NoteVault v2.9.2 is available immediately on the Google Play Store as a free, ad-supported application. Users can upgrade to the Premium tier for $1.49/month to remove ads and unlock advanced customization options.
