+title: Speedrun iExec
+description:
+  Understand iExec protocol in 3 minutes - privacy-first computing for Web3
+---
+
+# ⚡ Speedrun iExec
+
+**Privacy-first computing protocol.** Your data stays protected, your code runs
+in secure enclaves, results come back encrypted. Here's how it works.
+
+## The Protocol (Simple Version)
+
+### 🔒 Step 1: Protect Data
+
+Your sensitive data gets encrypted and stored online. Only you control who can
+access it.
+
+→ **Devtool**: [DataProtector](/manage_data/dataProtector) handles this for you
+
+### ⚙️ Step 2: Secure Computing (Workers)
+
+Code runs inside **secure enclaves** (TEEs) on iExec workers. The worker can
+access your data to process it, but only within the privacy-safe TEE
+environment - your data never leaves the secure bubble.
+
+### 🚀 Step 3: Run iApps
+
+You submit a **Task** = "Run this iApp on this protected data". The protocol
+finds available workers and executes everything confidentially.
+
+→ **Devtool**: [iApp Generator](/build_iapp/iapp-generator) helps you create and
+deploy iApps
+
+### 📦 Step 4: Get Results
+
+Results come back **encrypted to you**. Workers never see raw data, you never
+lose control.
+
+```
+Protected Data + iApp + Worker = Task → Encrypted Result
+```
+
+## What Each Piece Does
+
+### 🛡️ **Protected Data**
+
+Your data, encrypted. You set the rules: "Only these apps can use it, only for
+these purposes."
+
+### 🚀 **iApps**
+
+Your code, packaged to run on workers. Can be AI models, data processing
+scripts, any computation.
+
+### 🏭 **Workers (Secure Enclaves)**
+
+Computers that process your data inside privacy-safe TEE environments. They can
+access your data to work with it, but the TEE ensures it stays confidential and
+tamper-proof.
+
+### ⚡ **Deals**
+
+A job request: "Execute iApp X on protected data Y, send results to Z." The
+protocol handles the rest.
+
+## Real Example Walkthrough
+
+**AI Model Training (Private)**
+
+1. **Protect**: Medical researchers upload patient data → becomes Protected Data
+2. **Deploy**: AI company packages their model → becomes iApp
+3. **Execute**: Someone submits Task → "Train model on this data"
+4. **Result**: Model gets trained, researcher gets insights, raw data never
+   leaves enclave
+
+**Web3 Email**
+
+1. **Protect**: Users upload email contacts → Protected Data
+2. **Execute**: App submits Task → "Send email via Web3Mail iApp"
+3. **Result**: Email sent, addresses stay private, sender/receiver authenticated
+
+## Why This Architecture Rocks
+
+### ✅ **True Privacy**
+
+Data processing happens in secure enclaves. Workers can't peek, hackers can't
+break in.
+
+### ✅ **User Ownership**
+
+Data owners control access programmatically. Revoke permissions anytime.
+
+### ✅ **Composable**
+
+Any iApp can use any Protected Data (if authorized). Build once, use everywhere.
+
+### ✅ **Monetizable**
+
+Data owners get paid automatically when their data gets used in tasks.
+
+## Start Building
+
+Now that you get the protocol, pick your devtools:
+
+- **📧 Quick Win**: Add [Web3Mail](/use_iapp/web3mail) or
+  [Web3Telegram](/use_iapp/web3telegram.md) to your project ! (uses the protocol
+  under the hood)
+- **🛡️ Protect Data**: Try [DataProtector](/manage_data/dataProtector) to
+  encrypt your first dataset
+- **🚀 Build iApps**: Create confidential compute with
+  [iApp Generator](/build_iapp/iapp-generator)
+- **👋 Hands-On**: Follow our [Hello World](/overview/helloWorld) to see all
+  devtools working together
+
+---
+
+**TL;DR**: iExec = Encrypted data + Secure computing + Your code → Private
+results. Privacy made easy.

+title: What Is an iApp?
+description: Privacy-first applications that run on decentralized infrastructure
+---
+
+# 🚀 What Is an iApp?
+
+**Think about code, but it runs in a privacy-safe environment.** An iApp is just your regular application code (Python script, AI model, data processor) packaged to run inside secure enclaves.
+
+## Why Would You Want This?
+
+Simple: **to process sensitive data that users won't normally share.**
+
+Imagine you want to build:
+- An AI that analyzes personal health data
+- An email tool that needs access to contact lists  
+- A financial advisor that processes bank statements
+- A content filter that reads private messages
+
+Users have this data, but they won't give it to your regular app. **With iApps, they will.**
+
+## How It Works
+
+Your code runs in a **trusted execution environment** (TEE) - think of it as a "privacy bubble" that even iExec workers can't peek into.
+
+Users run your iApp when they want to **use** their Protected Data for something. Your code gets access to their protected data, performs actions with it - all without you ever seeing the raw data.
+
+## iApp Generator: Your Development Tool
+
+Creating iApps used to be complex. **iApp Generator** simplifies this by:
+
+- **Simulating TEE environment locally** - Test your code in conditions close to real execution
+- **Handling deployment** - Package and deploy with simple commands
+- **Managing dependencies** - Docker containers, environment setup, etc.
+
+```bash
+# Create your iApp (Python or Node.js supported)
+iapp init my-sentiment-analyzer
+cd my-sentiment-analyzer
+
+# Develop and test locally (simulates TEE environment)
+iapp test
+# Deploy to the network
+iapp deploy
+```
+
+*Note: iApp Generator currently supports Python and Node.js, but iApps can be built in any language that runs in Docker.*
+
+## Real Examples
+
+**Email Notification iApp**
+```python
+# User runs: "Send updates to my contacts about my project"
+contacts = load_protecteddata()  # User's protected contact list
+for contact in contacts:
+    send_email(contact, project_update_message)
+# → Emails sent directly, you never see the addresses
+```
+
+**Oracle Update iApp**  
+```python
+# User runs: "Update price oracle with my private trading data"
+trading_data = load_protecteddata()  # User's protected trading history
+average_price = calculate_weighted_average(trading_data)
+update_oracle_contract(average_price)
+# → Oracle updated with real data, trading history stays private
+```
+
+**Automated Transactions iApp**
+```python
+# User runs: "Buy tokens when my portfolio meets certain conditions"
+portfolio = load_protecteddata()  # User's protected portfolio data
+if should_buy_tokens(portfolio):
+    execute_trade(token_address, amount)
+# → Trade executed based on private data, portfolio details stay hidden
+```
+
+## 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
+
+### The Technical Reality
+
+```
+User's Private Data → Encrypted → TEE Environment → Your iApp uses it → Actions Performed
+```
+
+**Nobody sees the raw data except your code running inside the secure enclave.**
+
+Your iApp can send emails, update contracts, make transactions, trigger notifications - anything your code needs to do with the protected data. This isn't about trust - it's about **mathematical guarantees** that privacy is preserved.
+
+## What This Enables
+
+### 📧 **Private Communication**
+Users send emails, notifications, or messages using their protected contact lists without exposing recipient information.
+
+### 🔮 **Trustworthy Oracles**  
+Users contribute real data to oracles while keeping their private information confidential.
+
+### 🤖 **Personal AI Assistants**
+Users let AI models perform actions based on their private data - trading, scheduling, recommendations.
+
+### ⚡ **Automated Actions**
+Users set up automated workflows that use their private data to trigger actions, transactions, or updates.
+
+## ❓ Frequently Asked Questions
+
+
+::: details 📦 What can I build with iApps?

 title: What Is Protected Data?
-description: Understanding iExec's data protection mechanisms
+description: Data ownership meets privacy - understand how iExec gives you control
 ---
 
-# ❓ What Is Protected Data?
+# 🛡️ What Is Protected Data?
 
-Protected Data is iExec's revolutionary approach to data privacy and ownership.
-It allows you to maintain control over your data while enabling computation on
-it without exposing the raw information.
+**Your data, but with superpowers.** Protected Data is how iExec gives you blockchain-verified ownership over your information. You control who uses it, for what purpose, and you can get paid when it creates value.
 
-## Key Concepts
+## The Problem
 
-### Data Ownership
+Traditional apps treat your data like their property. You upload it, they own it. You lose control, they make money from it.
 
-- **You own your data**: The original data never leaves your control
-- **Granular permissions**: Decide who can access and use your data
-- **Revocable access**: Grant and revoke permissions at any time
+## The Solution: Blockchain-Verified Ownership
 
-### Privacy-Preserving Computation
+Protected Data flips this model. Here's how you protect data:
 
-- **Encrypted processing**: Data is encrypted during computation
-- **TEE (Trusted Execution Environment)**: Secure enclaves protect data during
-  processing
-- **Zero-knowledge**: Compute on data without revealing it
+```javascript
+const protectedData = await dataprotector.protectData({
+  name: 'my-contacts.json', 
+  data: { emails: ['user@example.com', ...] }
+});
+```
 
-### Monetization
+Now you have **blockchain-verified ownership** of this data. No one can access it without your explicit permission.
 
-- **Data marketplaces**: Sell access to your protected data
-- **Usage tracking**: Monitor how your data is being used
-- **Fair compensation**: Get paid for data usage
+## Access Control That Actually Works
 
-## How It Works
+Traditional permissions: "This app can access your contacts" *(forever, for anything)*
 
-1. **Protect**: Encrypt and register your data on the iExec network
-2. **Share**: Grant access permissions to specific users or applications
-3. **Monitor**: Track usage and maintain control
-4. **Monetize**: Earn from your data while keeping it private
+Protected Data permissions: "This newsletter app can use my contacts to send marketing emails, but only during weekdays, and I get 2€ per campaign."
 
-## Use Cases
+```javascript
+await dataprotector.grantAccess({
+  protectedData: protectedData.address,
+  authorizedApp: '0x123...', // Specific app
+  authorizedUser: '0xabc...', // Specific user
+  // Plus pricing, time limits, usage rules...
+});
+```
 
-- **Personal Data**: Health records, financial data, personal preferences
-- **Business Intelligence**: Market research, customer analytics, proprietary
-  datasets
-- **AI Training**: Training models without exposing sensitive data
-- **Research**: Collaborative research with privacy guarantees
+## Privacy-Safe Processing
 
-## Next Steps
+When apps use your Protected Data, they process it inside **secure enclaves** (TEEs). They get the results they need, but your raw data never leaves the privacy bubble.
 
-Ready to protect your data? Check out:
+### How the Technical Magic Works
 
-- [Getting Started with DataProtector](/manage_data/dataProtector/getting-started)
-- [DataProtector Guides](/manage_data/guides)
+Here's what actually happens under the hood:
+
+1. **Your data gets encrypted** and stored online (IPFS,Arweave..)
+2. **The decryption key** is stored in a secure TEE database 
+3. **Only authorized TEE workers** can retrieve this key to process your data
+4. **Apps run inside these TEE workers** - they can decrypt and use your data, but only within the secure enclave
+5. **Results come back encrypted** to you - the raw data never leaves the TEE environment
+
+```
+Your Data (encrypted, online) + Decryption Key (in TEE database) = Processing (only in authorized TEEs)
+```
+
+This architecture ensures that even iExec workers can't access your raw data - only the TEE environment can decrypt it for processing, and only when you've authorized it.
+
+## What This Enables
+
+### 📧 **Privacy-First Email Marketing**
+Your users upload their contact lists as Protected Data. Your newsletter app can send personalized emails without ever seeing the actual email addresses. Users stay private, you get engagement.
+
+### 🤖 **Ethical AI Training**  
+People contribute personal data (health records, preferences) as Protected Data. AI models can learn from this data without seeing individual information. Better AI, fair compensation, zero privacy trade-offs.
+
+### 🏢 **Confidential Business Intelligence**
+Companies protect their datasets but still collaborate on insights. Research partners get aggregate results without accessing raw competitive data. Innovation without information leaks.
+
+### 💰 **Data Monetization**
+Create marketplaces where data owners set their own terms. "Use my fitness data for $5/month, health insights only, no advertising." Automatic payments, programmable rules.
+
+
+
+## ❓ Frequently Asked Questions
+
+::: details 💰 How much does it cost?
+It's **free**! No gas fees on iExec's Bellecour network. You just need a Web3 wallet to sign transactions.
+:::
+
+::: details 📏 What's the maximum dataset size?
+It depends on your use case context. For standard cases (contacts, small datasets), no problem. For large volumes, [contact us](https://iex.ec/contact/) so we can assess if it fits your needs.
+:::
+
+::: details 💸 Can I monetize my data?
+Yes! You can sell access to your Protected Data with flexible pricing, subscriptions, etc. See the [Manage Data Monetization](/manage_data/guides/manage-data-monetization) guide for all details.
+:::
+
+::: details 🚀 How do I get started?
+You need a Web3 wallet (MetaMask, WalletConnect) and Node.js 16+. Follow [DataProtector Core](/manage_data/dataProtector/dataProtectorCore) for installation and first examples.
+:::
+
+
+
+::: details 🔒 Is my data really secure?
+Yes! Your data is encrypted and keys are stored in secure TEE environments. Even iExec workers can't see your raw data - only the authorized TEE environment can decrypt it for processing.
+:::
+
+## Why This Changes Everything
+
+### ✅ **True Ownership**
+Your data is blockchain-verified yours. Not "terms & conditions" yours, actually yours.
+
+### ✅ **Privacy by Design**
+Apps get utility without compromising privacy. No more "privacy vs functionality" trade-offs.
+
+### ✅ **Programmable Control**
+Set complex rules: "Use my data only for health insights, only on weekdays, only if I get paid 5€."
+
+### ✅ **Composable Privacy**
+Any iApp can use your Protected Data (if authorized). Build privacy-first ecosystems.

+
+## How iApp Execution Works
+
+When someone runs an iApp, here's what happens:
+
+1. **Task is submitted** to the iExec network with the iApp address and any
+   input data
+2. **TEE worker picks up the task** - only workers with secure enclaves can
+   execute iApps
+3. **iApp runs inside the TEE** - code executes in an isolated, tamper-proof
+   environment
+4. **Results are encrypted** and sent back to the user who initiated the task
+
+This execution model ensures that even the worker running your iApp can't see
+the data being processed.
+
+## Integration Challenge
+
+**You want to add privacy-first services to your application.** Whether you need
+email functionality, oracle data, or custom privacy-preserving logic, iApps can
+power your features without compromising user privacy.
+
+The question is: **how do you integrate them?**
+
+## Tools vs Other iApps
+
+Not all iApps are integrated the same way. There are three main categories:
+
+### 🛠️ **Tools (Ready-to-Use SDKs)**
+
+These are our **developer-friendly services** with polished SDKs:
+
+- **[Web3Mail](/use_iapp/web3mail)** - Private email functionality
+- **[Web3Telegram](/use_iapp/web3telegram)** - Secure messaging via Telegram
+- **[Oracle Factory](/use_iapp/oracle-factory)** - Decentralized oracle services
+
+**Why use these?** They come with:
+
+- ✅ Clean APIs and comprehensive documentation
+- ✅ Built-in user flows and UX patterns
+- ✅ Payment handling and error management
+- ✅ Ready-to-use examples and quick setup
+
+### 🛡️ **DataProtector (Process Protected Data)**
+
+If your goal is to **process Protected Data** specifically:
+
+- **[DataProtector](/manage_data/dataProtector)** - SDK for processing Protected
+  Data in TEE environments
+- Use `processProtectedData()` to run computation on encrypted datasets
+- Built-in privacy guarantees and access control
+
+**Why use this?** When you need to:
+
+- ✅ Process users' Protected Data with your custom logic
+- ✅ Combine multiple Protected Datasets securely
+- ✅ Get privacy-preserving analytics results
+- ✅ Keep data encrypted throughout the entire process
+
+### 🚀 **Custom iApps**
+
+These are **any other iApps** in the ecosystem:
+
+- Your own iApp that you built and deployed
+- Third-party iApps created by other developers
+- Specialized services for specific use cases
+
+**Integration is more manual** - you handle the execution flow, payments, and
+user experience yourself.
+
+## Three Integration Paths
+
+### Path 1: Using Tool SDKs (Recommended for Tools)
+
+```javascript
+// Clean, purpose-built APIs
+import { IExecWeb3mail } from '@iexec/web3mail';
+
+const web3mail = new IExecWeb3mail(web3Provider);
+await web3mail.sendEmail({
+  emailSubject: 'Welcome!',
+  emailContent: 'Thanks for signing up',
+  protectedData: userContactData,
+  contentType: 'text/html',
+});
+```
+
+### Path 2: Using DataProtector (For Processing Protected Data)
+
+```javascript
+// Process Protected Data directly
+import { IExecDataProtector } from '@iexec/dataprotector';
+
+const dataprotector = new IExecDataProtector(web3Provider);
+const result = await dataprotector.processProtectedData({
+  protectedData: userHealthData,
+  app: 'health-risk-analyzer.eth',
+  maxPrice: 100, // RLC
+});
+```
+
+### Path 3: Using iExec SDK (For Custom iApps)
+
+```javascript
+// General-purpose iApp execution
+import { IExec } from 'iexec';
+
+const iexec = new IExec({ ethProvider: web3Provider });
+const task = await iexec.task.run({
+  app: 'your-sentiment-analysis-iapp.eth',
+  dataset: protectedTweetData,
+  params: { model: 'bert-sentiment' },
+});
+```
+
+## Choose Your Path
+
+### ✅ **Use Tool SDKs if:**
+
+- You need email, messaging, or oracle functionality
+- You want quick integration with minimal setup
+- You prefer polished APIs and documentation
+- You want UX patterns already figured out
+
+**→ Start with [Web3Mail](/use_iapp/web3mail),
+[Web3Telegram](/use_iapp/web3telegram), or
+[Oracle Factory](/use_iapp/oracle-factory)**
+
+### ✅ **Use DataProtector if:**
+
+- You need to process users' Protected Data
+- You want built-in privacy guarantees for data processing
+- You're building analytics or AI services on encrypted datasets
+- You need to combine multiple Protected Datasets securely
+
+**→ Start with
+[DataProtector Core](/manage_data/dataProtector/dataProtectorCore) and
+[Protected Data Guide](/manage_data/dataProtector/what-is-protected-data)**
+
+### ✅ **Use iExec SDK if:**
+
+- You have a custom iApp (yours or third-party)
+- You need specialized functionality not covered by our tools
+- You want full control over the integration
+- You're building advanced privacy-preserving workflows
+
+**→ Start with [General iApp Integration](/use_iapp/guides) and
+[Payment Handling](/use_iapp/payment)**
+
+### 💡 **Not sure what you need?**
+
+Check out our [Hello World](/overview/helloWorld) tutorial to see all approaches
+in action.
+
+---
+
+**TL;DR**: Tools = Easy SDKs for common use cases. Custom iApps = Full
+flexibility with more integration work. Choose based on your needs! 🎯
