Masker: Private Chat & Vault

🔐 **Masker – Private Storage & Encrypted Messaging** Masker combines encrypted local storage with end-to-end encrypted messaging. Use the default Masker interface or optionally enable a utility-style disguise in Settings. Protect photos, videos, audio, notes, documents, and conversations with client-side encryption. Vault keys are derived on your device and are never sent to Masker servers. ⚠️ Lost credentials cannot be recovered by Masker, so your encrypted vault may become inaccessible. 🎭 **OPTIONAL DISGUISE MODE** Choose from six utility-style interfaces with matching launcher icons and app titles. Disguise Mode is optional and can be enabled or disabled in Settings. - 🧮 **Calculator** – Functional calculator with history and unit conversions. - 💱 **Currency Converter** – Real-time fiat exchange rates. - 🔊 **Audio Manager** – Sound profiles and volume controls. - 📰 **News Reader** – Live RSS headlines and article browsing. - 📈 **Finance Tracker** – Market indices, crypto, and stock watchlists. - 📅 **Calendar** – Personal events and schedules. 🗝️ **SEPARATE DECOY SPACE** - 🔒 **Primary credential** – Opens your main encrypted vault and private conversations. - 🎭 **Secondary credential** – Opens a separate decoy space with up to 15 items. Decoy items are stored locally without encryption. - 🧮 **Quick access** – Optional calculator trigger or press-and-hold gesture when Disguise Mode is enabled. - 👆 **Privacy gestures** – Optional shake and face-down actions to lock the app or return to the disguise screen. 🖼️ **PRIVATE ENCRYPTED VAULT** - 📸 **Photo & Video Vault** – Organize albums with preview thumbnails and a built-in encrypted media player. - 📝 **Secret Notes** – Formatted notes, checklists, color coding, and auto-save. - 🎙️ **Audio Vault** – Record voice memos or store audio files with waveform scrubbing. - 📁 **File Vault** – Store documents, PDFs, and archives. - 🌐 **Private Browser** – Browse in-app and clear session data with the session-wipe control. ⚠️ Encrypted media is protected inside the vault. Exported or shared copies may no longer be protected by Masker. 💬 **END-TO-END ENCRYPTED MESSAGING** - 🔐 **Zero-Knowledge Chat** – Multi-device ECDH (X25519) key agreement with AES-256-GCM authenticated encryption. Only you and your chat partner hold the encryption keys. - 🔔 **Privacy-Focused Notifications** – With a utility disguise active, alerts can use skin-themed text without sender names or message previews. - 🆔 **Anonymous Discovery** – Connect using Masker IDs or cryptographic phone number lookup. Phone numbers are one-way SHA-256 hashed and never stored in plaintext. - ⏳ **Disappearing Messages** – Automatic deletion timers from 24 hours up to one year. - 📤 **Encrypted Media Sharing** – Send encrypted photos, videos, and voice notes. - ✓ **Delivery & Read Receipts** – See status updates when devices connect. Timing depends on network and device availability. 🛡️ **PRIVACY & DATA PROTECTION** - 🔒 **Private Content** – Masker does not log vault file contents or chat plaintext. - ☁️ **Service Transparency** – Masker uses Firebase for messaging and AdMob for advertising. See the Privacy Policy for details about data collected by these services. - ♻️ **Data Clear Protection** – When configured, this optional feature can help restore supported setup and recovery data after app storage is cleared. ⚠️ Data Clear Protection does not guarantee recovery of every file or prevent data loss. **Take control of your digital privacy with Masker.**
