MyYaad - Privacy Vault for AI Chrome extension security report

MyYaad — Privacy Vault for AI protects your personal data every time you use an AI chatbot. Before your prompt reaches ChatGPT, Claude, Gemini, or DeepSeek, MyYaad automatically replaces real personal information — names, emails, phone numbers, addresses, company names — with realistic-looking shadow values. The AI sees fake data, you get real answers. When the response comes back, MyYaad restores your real values seamlessly. HOW IT WORKS 1. You type normally — write your prompt as you always would, using real names, emails, and details. 2. MyYaad intercepts — before your prompt is sent, the extension detects vault entries and swaps them with realistic shadow values. "Sarah Chen" becomes "Person-7f3a2d", your email becomes "email-4b82c1@shadow.local". 3. The AI responds — it works with the shadow data and gives you a real, useful answer. 4. MyYaad restores — the response is de-shadowed so you see your real values, not the fakes. The AI provider never sees your real personal information. You get the power of AI without the privacy cost. WHAT MAKES MYYAAD DIFFERENT - Realistic shadows — not redacted blanks or [REMOVED] tags. The AI gets plausible fake data so responses stay coherent and useful. - Works across 4 major providers — ChatGPT, Claude, Gemini, and DeepSeek, all from one extension. - Provider isolation — each AI provider gets different shadow values, so no provider can cross-reference your data with another. - Document context — upload PDFs, spreadsheets, or documents to use as context in your prompts, with shadow protection applied automatically. - Vault persistence — your shadow mappings are consistent across sessions, so the AI maintains context over time. LOCAL. NO CLOUD. NO ACCOUNT. MyYaad is built on a zero-trust architecture. All processing happens on your device. The extension communicates only with the MyYaad desktop app running on localhost — no data ever leaves your computer. There are no external servers, no analytics, no telemetry, and no account required. Your data never touches our servers because we don't have servers. REQUIREMENTS - MyYaad desktop app (download at myyaad.com) must be running. - Chrome browser. - No account or sign-up required. Install and go. WHAT'S INCLUDED The core privacy protection includes unlimited shadow transforms across all 4 providers — no trial period, no paywall, no account required.
