AI Privacy Firewall

Use AI.
Keep Your Data.

Other tools mask your data with [NAME] placeholders — breaking AI responses. MyYaad replaces it with realistic shadows that keep AI working perfectly. Each provider gets different shadows. Your real data never leaves your device.

How It Works

Three steps.
Zero exposure.

You type normally. MyYaad handles the rest — before anything reaches the AI.

01

Store Your Data Locally

Add your personal details — name, company, email, dates — to an AES-256 encrypted vault on your device. Nothing touches the internet.

Shadows Replace Real Data

Before your prompt reaches any AI, the Shadow Engine swaps real details with realistic fakes. Each provider gets different shadows.

03

You See the Real Response

When the AI replies using shadow names, MyYaad translates them back automatically. Perfect answer, zero exposure.

“Based on your background, Alex_B7K_9...”

→ Restored to “John Mitchell”

Protected Data Types

Shadow Engine

They see shadows.
You hold truth.

Other tools replace your name with [NAME] — the AI gets confused, responses break. MyYaad generates realistic fake data that keeps AI responses useful. And unlike cloud firewalls, nothing leaves your device.

Provider Isolation

Each AI gets a different shadow — even if every provider is breached simultaneously, they can't correlate your data across services.

Trust Model

Privacy is not a setting.
It's the architecture.

Other tools say ‘trust us, we don't log.’ Or route your data through EU servers and call it private. MyYaad doesn't ask you to trust anyone — it makes exposure physically impossible.

On Your Device (Safe Zone)
  • Encrypted vault (your real data)
  • Shadow Engine (all processing)
  • Provider salts (OS keychain)
  • Audit log (tamper-evident)
  • Document parser + search index
What Leaves Your Device
  • Shadow values only (fake but realistic)
  • No real names, emails, dates, or numbers
  • Different shadows per provider
  • Cannot be reversed without your device
  • Breach-proof: shadows are useless without your device keys

But Why Not Just...

We get it. There are alternatives.
Here's why they fall short.

"Just use a free PII blocker"

Generic [NAME] placeholders confuse the AI — your responses break. No vault means nothing is remembered. No provider isolation means one breach exposes everything. MyYaad’s realistic shadows keep AI responses useful.

"Route it through a cloud firewall"

Cloud firewalls like ZeroTrusted.ai still send your data through someone else’s server. Their server sees your real data before stripping it. MyYaad transforms locally — your real data never touches a network.

"Use a private AI chatbot instead"

Private chatbots like Venice.ai or CamoCopy lock you into their models. You lose access to ChatGPT, Claude, Gemini. MyYaad works with every AI — you pick the best model, we protect the data.

Built for Real Work

Built for people who use
AI with real data.

I tried a PII blocker first — it replaced my client’s name with [NAME] and the AI gave me nonsense back. MyYaad uses realistic fake names so the AI responses actually make sense. I can see exactly what leaves my device, and my clients’ real details never touch OpenAI’s servers.

Our district considered a cloud-based AI firewall but it still routed student data through their servers — that’s a FERPA violation waiting to happen. MyYaad processes everything on the teacher’s own laptop. Nothing leaves the device. Compliance sorted.
