-## The Trust Model
-
-Here's why users will actually use your iApp with their private data:
-
-### What Users See
-
-- ✅ "This code runs in a secure enclave, not on the developer's servers"
-- ✅ "My data gets used privately for actions I want"
-- ✅ "Even iExec workers can't see my data during execution"
-- ✅ "I can revoke access anytime"
-
-### What You Get
-
-- ✅ Users willing to use your services with their sensitive data
-- ✅ New business models around privacy-preserving analytics
-- ✅ Competitive advantage through privacy guarantees
-
 ## How It Works
 
 Your code runs in a Trusted Execution Environment (TEE) a secure area inside
 specific processors (Intel SGX/TDX chipset). Everything that happens there stays
 private and protected, even from the operating system.
 
-An authorized user can trigger an iApp that processes someone's protected data inside this private environment. The data is used, but never exposed, not even to the person running the app.

+## The Trust benefits
+
+Why users actually trust iApps with their private data
+
+### For Users – You stay in control
+
+- Your data stays private, even from the iApp creator or iExec.
+- Your code runs in a secure enclave, not on someone else’s server.
+- You define what happens to your data, and you can revoke access anytime.
+
+### For Builders – Trust becomes your best feature
+
+- Users are confident sharing sensitive data with your app.
+- Unlock new business models with privacy-preserving features.
+- Stand out with built-in privacy, programmable access, and verifiable
+  execution.
