Privacy by Design. Security by Mathematics.
What you whisper in the quiet of the night belongs strictly to you. Here is the verified cryptographic blueprint of how Acyri separates raw audio from encrypted memories.

KMS ENVELOPE VAULT
0 Bytes Audio Saved • AES-256
“If Acyri never stores voice audio, how does it remember my name and past conversations?”
Many apps either record your raw voice files indefinitely or forget you immediately. Acyri solves this with a two-tiered cryptographic isolation protocol that completely vaporizes audio while sealing extracted facts:

Raw Audio is Vaporized
Your spoken audio travels in real-time WebRTC streams through volatile memory (RAM). Once speech-to-text tokenization finishes, the audio buffer is wiped clean. Zero audio files are saved to disk.
Factual Knowledge Extracted
Only the distilled, supportive facts you share (such as family names, milestones, or personal preferences) are formatted into structured text memory points.

Sealed in AES-256 Vault
The factual text is immediately encrypted with your per-user AES-256-GCM key wrapped by Google Cloud KMS. It sits as random cipher blocks until you log into your next session.
Zero Compromise
6 Cryptographic Guarantees Built Into Acyri
Engineered for absolute personal safety, confidentiality, and data sovereignty.

1. Zero Voice Recording (Ephemeral RAM)
Industry Risk: Other voice apps record and archive your microphone audio to disk for quality audits and human reviews.
Acyri Guarantee: Acyri streams audio in real time directly through ephemeral volatile memory (RAM). The moment speech-to-text tokenization completes, the raw audio buffer is permanently wiped. No .wav, .mp3, or audio files ever touch a hard drive.

2. Application Envelope Encryption
Industry Risk: Database breaches expose plaintext chats, thoughts, and intimate secrets to hackers or rogue insiders.
Acyri Guarantee: Every memory and reflection is encrypted at the application layer using AES-256-GCM with individual per-user Data Encryption Keys (DEKs) wrapped by Google Cloud KMS. Even database administrators see only random cryptographic cipher blocks.

3. Never Used for AI Model Training
Industry Risk: Tech companies feed private user conversations into public foundation models, risking sensitive leaks.
Acyri Guarantee: Your intimate conversations are never used to train public models—not by Acyri, and not by our foundation model partners (Google, OpenAI, Anthropic). We operate under strict zero-retention enterprise agreements.

4. Cryptographic Key Shredding
Industry Risk: Apps retain "soft-deleted" records in backup servers for years without truly purging the content.
Acyri Guarantee: When you tap "Delete All" or delete your account, we perform cryptographic key shredding: your Google Cloud KMS key is permanently destroyed, rendering all stored ciphertext mathematically impossible to decrypt by anyone forever.

5. Total Memory Transparency Vault
Industry Risk: AI companions build mysterious hidden psychological profiles about you that you cannot view or contest.
Acyri Guarantee: Acyri gives you 100% transparency. You can open your private Memory Vault anytime to inspect every single fact Acyri remembers, edit any detail, or click to delete individual memories with a single tap.

6. Elevated Health & Emotional Consent
Industry Risk: Mental health and emotional data are harvested and sold to health insurers and third-party data brokers.
Acyri Guarantee: Acyri complies with stringent consumer health data regulations (Washington MHMDA, California SB 243). Personal health observations require affirmative consent and are shielded behind elevated cryptographic barriers.
