Privacy Policy & Security Architecture

1. Core Philosophy: Zero-Knowledge Architecture

Mumline was founded on the uncompromising principle that digital privacy is a fundamental human right. Our applications (including Ciphera, QuietDrop PRO, Storage Hunter PRO, Calculator Vault, and NOVA Reality Launcher) are engineered from the silicon up to function with zero knowledge of your identity, contacts, communications, or files.

2. Zero Data Collection

When you browse Mumline or use our applications:

• We do not require or collect phone numbers, email addresses, or real names.
• We do not embed third-party analytics trackers, advertising SDKs, or telemetry daemons.
• We do not log client IP addresses or user browsing sessions.
• We do not sell, rent, monetize, or disclose user telemetry to any third parties or data brokers.

3. Cryptographic Forward Secrecy

Communications conducted over Ciphera utilize dynamic ephemeral Curve25519 (X25519) ECDH key negotiation combined with authenticated 256-bit Galois/Counter Mode (AES-256-GCM) encryption. Signaling relays pass ciphertext through transient volatile memory (RAM) only. No unencrypted payload ever touches a physical storage disk or database.

4. Verified Binary Transparency & SHA-256 Hashes

Every Android application package (APK) distributed on Mumline is accompanied by a cryptographically published SHA-256 checksum and a public VirusTotal clean certificate. Users are encouraged to verify checksums prior to installation to ensure binaries are pristine and untampered.

5. Device Licensing

Commercial application licenses are cryptographically verified via hardware-bound RSA signatures tied directly to on-device AndroidKeyStore identifiers. No user account database or password repository is maintained.
