AI Memory That Only You Can Unlock

Three tiers of persistence. One guarantee: your data stays yours.

How It Works

1
Choose your memory tier
Professional for encrypted daily AI with 7–90 day retention. Executive for indefinite, user-keyed memory with 70B-parameter access. Ghost Mode toggle available on both for ephemeral sessions.
2
Your data is encrypted
AES-256-GCM + CRYSTALS-Kyber post-quantum encryption protects every memory entry before it touches our servers.
3
Only you hold the key
For Permanent Vault, your passphrase or hardware token unlocks your vault client-side. We never see your data in plaintext.

Encryption Under the Hood

Private Vault uses a hybrid classical + post-quantum encryption scheme. Even if classical encryption is broken by future AI or quantum computing, the post-quantum layer remains intact.

Data at Rest
AES-256-GCM
FIPS 140-2 validated. Random IV per record. GCM provides authentication.
Key Encapsulation
CRYSTALS-Kyber (ML-KEM)
NIST FIPS 203 standardized. Quantum-resistant key exchange.
Audit Signatures
CRYSTALS-Dilithium (ML-DSA)
Post-quantum digital signatures. Tamper-proof audit trail.
Key Derivation
Argon2id
Memory-hard. 64MB memory cost, 3 iterations, 4 threads.
In Transit
TLS 1.3 + PQ KEM
Post-quantum key exchange protects data in transit too.
Processing
TEE Enclaves
Hardware-isolated execution. Even our infrastructure can't observe decrypted memory.
