Feb 20, 2026Why Zero-Knowledge Privacy Matters for Factory Owners
In the stone industry, trust is the only currency. If a factory owner joins a SaaS, they worry: "Can the developer see my profit margins?"
In DONOZ, the answer is: **No. I literally can't.**
### The "Blind Ciphertext Store" Architecture
We use a strategy called the **Blind Ciphertext Store**.
1. **Local Encryption**: Plaintext (Client names, rates) never leaves the user's browser.
2. **Web Crypto API**: The data is encrypted locally using industrial-grade cryptography.
3. **Zero Visibility**: My database only sees base64-encoded "blobs" of noise.
### Why go this far?
Because your business secrets are yours alone. Even if our server were compromised, your data remains a dark, unreadable vault without your specific Master Key. It's security that respects the independence of the industrialist.
