Ghost Vault: encrypt files

Ghost Vault is your private secret photo lock and encrypted file vault. Hide photos, lock videos, and protect confidential documents with zero-knowledge AES-256.

Tired of cloud leaks, prying eyes, or apps that sync your private memories to unknown servers? Ghost Vault is an offline-first encrypted vault engineered to give you absolute control over your private files, sensitive tax documents, family photos, personal videos, and confidential notes.

Built with military-grade authenticated envelope encryption (AES-256-GCM) and hardware-backed biometric security, Ghost Vault guarantees that only you possess the keys to decrypt your data. Even if someone accesses your phone storage, your encrypted vault remains impenetrable.

🛡️ Zero Cloud. Zero Telemetry. 100% Privacy.

Most "secret locker" apps upload your media to third-party ad networks or unencrypted cloud databases. Ghost Vault operates on a strict zero-knowledge principle: we do not track you, we do not require accounts or phone numbers, and we never touch your encryption keys.

Whether you need a discreet gallery locker to hide secret photos, a secure document safe for tax and identity records, or a private offline vault for personal media, Ghost Vault provides state-of-the-art cryptographic protection in a clean, ad-compliant interface.
