About this app

Halonex™ Mail is a secure, privacy-first email client built exclusively for institutional and corporate email accounts. Designed from the ground up with military-grade encryption, zero third-party trackers, and full compliance with India's Digital Personal Data Protection (DPDP) Act 2023, Halonex™ Mail puts your privacy where it belongs: in your hands.

𝗕𝘂𝗶𝗹𝘁 𝗳𝗼𝗿 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆. 𝗡𝗼𝘁 𝗦𝘂𝗿𝘃𝗲𝗶𝗹𝗹𝗮𝗻𝗰𝗲. Unlike mainstream email apps, Halonex™ Mail collects zero analytics, integrates zero ad networks, and transmits zero data to third parties. Every email, every draft, every credential is encrypted with AES-256 on your device — protected by hardware-backed keys in your phone's Trusted Execution Environment (TEE).

𝗘𝗻𝗰𝗿𝘆𝗽𝘁𝗶𝗼𝗻 𝗘𝘃𝗲𝗿𝘆𝘄𝗵𝗲𝗿𝗲 • AES-256 encrypted local database (SQLCipher) for all emails and metadata • AES-256-GCM encrypted credentials via Android Keystore • TLS 1.3 with certificate pinning — stops man-in-the-middle attacks even if a rogue root certificate is installed on your device • Zero plaintext ever written to disk

𝗥𝗲𝗮𝗹-𝗧𝗶𝗺𝗲 𝗣𝗵𝗶𝘀𝗵𝗶𝗻𝗴 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻 Powered by Halonex™ Vanta, every email you open is scanned for malicious links using privacy-preserving SHA-256 hash lookups. Only cryptographic hashes of domains are sent — never your email content, never your personal data. Phishing emails are flagged with a clear visual warning before you click anything.

𝗟𝗼𝗰𝗮𝗹-𝗙𝗶𝗿𝘀𝘁 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 Emails load instantly from your encrypted local database — not from the network. Background sync keeps your inbox updated every 15 minutes (consent required), while foreground sync refreshes every 60 seconds. Offline? No problem — actions like mark-as-read, star, move, and delete work offline and replay automatically when connectivity returns.

𝗕𝗶𝗼𝗺𝗲𝘁𝗿𝗶𝗰 𝗔𝗽𝗽 𝗟𝗼𝗰𝗸 Lock Halonex™ Mail behind your fingerprint or face. Configurable inactivity timeout. Uses Android's BiometricPrompt with Class 3 (BIOMETRIC_STRONG) hardware-backed authentication.

𝗥𝘂𝗻𝘁𝗶𝗺𝗲 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 • Root & jailbreak detection • Emulator detection • Hooking framework detection (Frida, Xposed) • APK integrity verification (anti-tamper) • Screenshot & screen recording protection (FLAG_SECURE) • Secure clipboard: auto-clears after 60 seconds, clears on app background • Sensitive data wiped from memory immediately after use • Zero logging in release builds, ProGuard strips all log calls

𝗙𝘂𝗹𝗹 𝗘𝗺𝗮𝗶𝗹 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝗮𝗹𝗶𝘁𝘆 • IMAP/SMTP over TLS with strict certificate validation • Full folder management (Inbox, Sent, Drafts, Trash, Spam, and custom folders) • Compose, reply, forward with rich formatting • Draft saving and management • Star/flag emails • Search across your mailbox • Smart notifications with lock-screen privacy (content hidden on lock screen) • "Mark as Read" directly from notifications
