+# RR3 Community Server - Frequently Asked Questions (FAQ)
+
+**Last Updated:** February 23, 2026  
+**Project:** Real Racing 3 Community Server + APK Mod
+
+---
+
+## 🤔 "Just Read The Code" - Common Questions
+
+**Before asking, check here first!** All code is public on Gitea - but here are the most common questions answered quickly.
+
+---
+
+## 🔐 Security & Encryption
+
+### Q: Is the network communication encrypted?
+
+**A:** Yes AND No - it depends what you mean:
+
+- **Transport (HTTPS/TLS):** ✅ YES - data is encrypted in transit
+- **Application-level encryption:** ❌ NO - payloads are plaintext over HTTPS
+- **Certificate validation:** ❌ DISABLED - accepts any SSL certificate
+
+**Details:** The game uses HTTPS but disables certificate validation, making it vulnerable to MITM attacks but also allowing self-signed certificates for community servers.
+
+**Read More:** `NETWORK-SECURITY-ANALYSIS.md` (16 KB full analysis)
+
+---
+
+### Q: Are the APK network files/code encrypted or obfuscated?
+
+**A:** ❌ NO - completely readable
+
+- **Code obfuscation:** NONE (no ProGuard/R8)
+- **Class names:** Readable (Http.java, HttpRequest.java, etc.)
+- **Method names:** Readable (sendRequest, postData, etc.)
+- **Strings:** Plaintext in smali files
+
+**What IS encrypted:** Local save data on device (AES-256) - NOT network traffic
+
+**Why it matters:** Made reverse engineering easy! If EA had obfuscated the code, this project would be 10x harder.
+
+**See for yourself:**
+- `smali_classes2/com/firemint/realracing/Http.smali` - readable class names
+- `smali_classes2/com/ea/nimble/SynergyEnvironmentImpl.smali` - readable methods
+
+---
+
+### Q: What encryption DOES the game use?
+
+**A:** Only for local storage:
+
+- **Algorithm:** AES/CBC/PKCS5Padding (256-bit keys)
+- **Key derivation:** PBKDF2WithHmacSHA1 (997 rounds)
+- **Used for:**
+  - Saved game data on device
+  - Cached authentication tokens
+  - SharedPreferences persistence
+
+**Code location:** `smali_classes2/com/ea/nimble/Encryptor.smali`
+
+**Network payloads:** NOT encrypted (plaintext over HTTPS)
+
+---
+
+## 🌐 Network & Server
+
+### Q: Will the game contact EA servers?
+
+**A:** ❌ NO - EA URLs eliminated in v14 APK
+
+**What we changed:**
+- AndroidManifest.xml: `configuration="live"` → `"customized"`
+- EA production URLs unreachable (only if both user config AND manifest fail)
+- URL Priority: SharedPreferences > Manifest fallback > Never EA
+
+**Details:** `EA-URL-ELIMINATION.md` (11 KB)
+
+**Test it yourself:**
+1. Install APK
+2. Monitor with `adb logcat | grep eamobile`
+3. Should see ZERO EA domain connections
+
+---
+
+### Q: How does the server URL configuration work?
+
+**A:** 3-tier priority system:
+
+**Priority 1 (Highest):** SharedPreferences
+- File: `/data/data/com.ea.games.r3_row/shared_prefs/rr3_community_server.xml`
+- Key: `"server_url"`
+- Set by: User input in ServerSetupActivity (first launch)
+
+**Priority 2:** AndroidManifest.xml
+- Meta-data: `NimbleCustomizedSynergyServerEndpointUrl`
+- Default: `http://localhost:5001`
+- Used if SharedPreferences empty
+
+**Priority 3:** EA URLs (UNREACHABLE)
+- Only accessible if both Priority 1 AND 2 fail
+- With `configuration="customized"`, this never happens
+
+**Code:** Lines 959-985 in `SynergyEnvironmentImpl.smali`
+
+---
+
+### Q: What server endpoints are required?
+
+**A:** 73 Synergy API endpoints total
+
+**Status:**
+- Implemented: 58/73 (79%)
+- Missing: 15 endpoints
+
+**Critical missing:**
+- Events Service: 0/4 (blocks career mode)
+- Time Trials: 0/5
+- Leaderboards: 3/4
+- Multiplayer: 0/10+
+
+**Full list:** `SERVER-ENDPOINTS-ANALYSIS.md` (12.7 KB)
+
+---
+
+### Q: Can I use self-signed SSL certificates?
+
+**A:** ✅ YES - the APK accepts ANY certificate
+
+**Why:** Certificate validation is disabled (`ALLOW_ALL_HOSTNAME_VERIFIER`)
+
+**Options:**
+1. **Let's Encrypt** (recommended) - free, valid certificates
+2. **Self-signed** - works perfectly, free
+3. **No SSL (HTTP)** - works but not recommended for production
+
+**Generate self-signed:**
+```bash
+openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
+```
+
+---
+
+## 🛠️ APK Modifications
+
+### Q: What was changed in the v14 APK?
+
+**A:** Minimal changes to eliminate EA servers:
+
+**File:** AndroidManifest.xml
+- **Line 126:** `android:value="live"` → `android:value="customized"`
+- **Lines 127-128:** Added fallback URL `http://localhost:5001`
+
+**Code added:**
+- `CommunityServerManager.smali` - manages server URL preferences
+- `ServerSetupActivity.smali` - first-launch server input dialog
+- `OfflineModeManager.smali` - online/offline toggle
+
+**That's it!** No other game code modified.
+
+---
+
+### Q: How do I build the APK myself?
+
+**A:** 3-step process:
+
+```bash
+# 1. Decompile
+apktool d RealRacing3.apk -o rr3-apk
+
+# 2. Make changes (edit AndroidManifest.xml, etc.)
+
+# 3. Rebuild
+apktool b rr3-apk -o RR3-modified-unsigned.apk
+
+# 4. Sign
+apksigner sign --ks your-keystore.jks \
+  --out RR3-modified-signed.apk \
+  RR3-modified-unsigned.apk
+```
+
+**Full guide:** `APK-BUILD-AND-TESTING-GUIDE.md` (10 KB)
+
+**Requirements:**
+- Java 11+ (OpenJDK recommended)
+- apktool 2.10.0+
+- Android SDK build-tools
+
+---
+
+### Q: Why isn't ProGuard/obfuscation used?
+
+**A:** EA/Firemonkeys chose not to obfuscate
+
+**Likely reasons:**
+- Easier debugging/crash reports
+- Faster build times
+- Game logic not "secret" (offline mobile game)
+- Anti-cheat handled server-side (when servers existed)
+
+**Result:** Made our community server project MUCH easier! 🎉
+
+---
+
+## 🎮 Gameplay & Features
+
+### Q: Can I play offline?
+
+**A:** ✅ YES - offline mode implemented
+
+**How to enable:**
+- Settings menu → Toggle "Offline Mode"
+- Saves to: `rr3_offline_settings.xml`
+- Key: `offline_mode_enabled`
+
+**Limitations:**
+- No leaderboards
+- No multiplayer
+- No cloud save sync
+- Career mode works (if Events Service implemented)
+
+**Code:** `smali_classes2/com/firemint/realracing/OfflineModeManager.smali`
+
+---
+
+### Q: Does multiplayer work?
+
+**A:** ❌ NOT YET
+
+**Status:** 0/10+ multiplayer endpoints implemented
+
+**Blockers:**
+- Real-time matchmaking system needed
+- Race synchronization logic required
+- Anti-cheat server-side validation
+- P2P or relay server architecture decision
+
+**Priority:** LOW (Phase 3+) - single-player first
+
+---
+
+### Q: Can I charge for in-app purchases?
+
+**A:** ❌ NO - EA's legal restriction
+
+**EA's Terms:**
+- ✅ Community servers allowed
+- ✅ Donations for server costs allowed
+- ❌ Cannot charge for in-app purchases (real money)
+- ❌ Cannot charge for the APK itself
+
+**Why:** EA retains the game IP and rights
+
+**Alternative:** Accept donations for server hosting (PayPal, Patreon, etc.)
+
+---
+
+## 🐛 Troubleshooting

+
+### Understanding Code Flow:
+
+**Server URL Resolution:**
+```
+1. Game starts → MainActivity.smali
+2. Check config → CommunityServerManager.checkServerUrl()
+3. Get URL → SynergyEnvironmentImpl.getSynergyDirectorServerUrl()
+   ├─ Priority 1: SharedPreferences ("rr3_community_server.xml")
+   ├─ Priority 2: AndroidManifest.xml (NimbleCustomizedSynergyServerEndpointUrl)
+   └─ Priority 3: EA URLs (UNREACHABLE with configuration="customized")
+4. Make API call → Http.smali or HttpRequest.smali
+```
+
+**First Launch Flow:**
+```
+1. MainActivity.smali → onCreate()
+2. Check if first launch (no SharedPreferences)
+3. Launch → ServerSetupActivity.smali
+4. User inputs server URL
+5. Save → CommunityServerManager.saveServerUrl()
+6. Restart → MainActivty with URL configured
+```
+
+**Network Request Flow:**
+```
+1. Game needs data → SynergyNetwork.smali
+2. Build request → URL + parameters
+3. Send via → Http.smali (POST) or HttpRequest.smali (GET/POST)
+4. TLS handshake → CloudcellTrustManager (accepts all certs)
+5. Receive response → Parse JSON
+6. If save needed → Encryptor.smali (AES-256)
+```

+# RR3 Network Security Analysis
+
+**Analysis Date:** February 23, 2026  
+**APK Version:** Real Racing 3 v14.0.1  
+**Security Auditor:** Community Server Project
+
+---
+
+## 🔒 Executive Summary
+
+**Overall Security Rating:** 🔴 **HIGH RISK - Production Not Recommended**
+
+The RR3 APK's network implementation uses HTTPS/TLS for encryption but **disables all certificate validation**, making it vulnerable to Man-in-the-Middle (MITM) attacks. This was likely an intentional design choice by EA/Firemonkeys to support:
+- Development/testing environments
+- Custom server configurations
+- Self-signed certificates
+
+**For Community Servers:** This is actually **beneficial** since it allows:
+- ✅ Self-signed SSL certificates (no need for paid certificates)
+- ✅ Let's Encrypt certificates without pinning
+- ✅ Custom domain names without hostname verification
+- ✅ Easy local testing (localhost, 10.0.2.2, etc.)
+
+**Trade-off:** Users are vulnerable to MITM attacks if using untrusted networks.
+
+---
+
+## 🔍 Detailed Security Analysis
+
+### 1. Encryption Status
+
+#### ✅ **Transport Layer Encryption: ENABLED**
+
+**Protocol:** TLS/SSL over HTTPS  
+**Implementation:** Native Java `HttpsURLConnection` and `SSLContext`
+
+```smali
+# From HttpRequest.smali (CloudCell API)
+invoke-static {v3}, Ljavax/net/ssl/SSLContext;->getInstance(Ljava/lang/String;)
+# Uses "TLS" protocol
+```
+
+**What This Means:**
+- All network traffic is encrypted in transit
+- Data cannot be read by passive network observers
+- Eavesdropping on open WiFi networks requires active MITM attack
+
+---
+
+### 2. Certificate Validation: DISABLED ⚠️
+
+#### 🔴 **Critical Vulnerability #1: Custom TrustManager Bypasses Validation**
+
+**File:** `com/firemonkeys/cloudcellapi/CloudcellTrustManager.java`
+
+**Code Analysis:**
+```java
+public class CloudcellTrustManager implements X509TrustManager {
+    private boolean m_bSSLCheck = false;  // Default: DISABLED
+    
+    @Override
+    public void checkServerTrusted(X509Certificate[] chain, String authType) {
+        // Only checks if m_bSSLCheck is true
+        if (this.m_bSSLCheck) {
+            // Validates certificate chain
+            // Checks expiration dates
+            // Checks CA signing
+        } else {
+            // DOES NOTHING - accepts all certificates!
+        }
+    }
+}
+```
+
+**Default Behavior:** SSL validation is **OFF** by default (`m_bSSLCheck = false`)
+
+**Impact:**
+- Accepts expired certificates
+- Accepts self-signed certificates
+- Accepts certificates from untrusted CAs
+- Accepts certificates for wrong domains
+
+---
+
+#### 🔴 **Critical Vulnerability #2: Empty TrustManager in Http.java**
+
+**File:** `com/firemint/realracing/Http.java`
+
+**Code Analysis:**
+```smali
+# Http$1.smali (Anonymous TrustManager class)
+.method public checkServerTrusted([Ljava/security/cert/X509Certificate;Ljava/lang/String;)V
+    .locals 0
+    return-void  # DOES NOTHING!
+.end method
+```
+
+**Behavior:** The `checkServerTrusted()` method is **completely empty** - returns immediately without any validation.
+
+**Impact:**
+- Zero certificate validation
+- Accepts ANY certificate
+- No expiration checks
+- No CA chain validation
+
+---
+
+### 3. Hostname Verification: DISABLED ⚠️
+
+#### 🔴 **Critical Vulnerability #3: ALLOW_ALL_HOSTNAME_VERIFIER**
+
+**Files:**
+- `com/firemonkeys/cloudcellapi/HttpRequest.java` (line 111)
+- `com/firemint/realracing/Http.java` (line 180)
+
+**Code:**
+```java
+HttpsURLConnection.setDefaultHostnameVerifier(
+    SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
+);
+```
+
+**What This Does:**
+- Disables hostname verification entirely
+- Accepts certificates for ANY domain
+- Example: Certificate for `attacker.com` accepted when connecting to `rr3.example.com`
+
+**Attack Scenario:**
+1. Attacker creates certificate for `evil.com`
+2. DNS hijacked to point `rr3.example.com` → attacker's server
+3. Game accepts `evil.com` certificate for `rr3.example.com` connection
+4. Attacker can intercept all traffic
+
+---
+
+### 4. Certificate Pinning: NOT IMPLEMENTED
+
+**Status:** ❌ No certificate pinning found
+
+**OkHttp CertificatePinner Detected:**
+```smali
+# Found in dependencies
+Lokhttp3/CertificatePinner;
+```
+
+**But:** No pin hashes configured, so pinning is not active.
+
+**What This Means:**
+- No hardcoded certificate fingerprints
+- Game doesn't validate specific server certificates
+- Any valid-looking certificate accepted
+
+**For Community Servers:** This is **GOOD** - allows any SSL certificate!
+
+---
+
+## 🚨 Vulnerability Summary

+---
+
+### Attack Vector #2: DNS Hijacking
+
+**Scenario:**
+1. Attacker compromises user's DNS (router hack, malicious DNS server)
+2. User inputs server URL: `https://rr3.example.com`
+3. DNS resolves to attacker's IP instead
+4. Attacker presents fake certificate
+5. Game accepts it due to disabled validation
+6. User unknowingly connects to malicious server
+
+**Data at Risk:**
+- User credentials (if implemented)
+- Progress data sent to attacker
+- Malicious game modifications
+
+**Likelihood:** 🟢 LOW (requires DNS compromise)  
+**Impact:** 🔴 HIGH (complete server impersonation)
+
+---
+
+### Attack Vector #3: Local Network Interception
+
+**Scenario:**
+1. User on compromised local network (infected router, corporate MITM)
+2. Attacker performs transparent proxy
+3. Attacker replaces SSL certificates
+4. Game accepts replacement certificates
+5. All traffic flows through attacker
+
+**Data at Risk:**
+- All network communications
+- Real-time gameplay data
+- Server responses
+
+**Likelihood:** 🟢 LOW (requires network access)  
+**Impact:** 🔴 HIGH (complete visibility)
+
+---
+
+## 🛡️ Security Recommendations
+
+### For Community Server Operators
+
+#### ✅ **Option 1: Use Let's Encrypt (Recommended)**
+
+**Pros:**
+- Free, automated certificates
+- Valid CA signatures
+- Works with ANY SSL validator
+- Easy renewal (90-day cycle)
+
+**Setup:**
+```bash
+# Using Certbot
+certbot certonly --standalone -d rr3.example.com
+
+# Auto-renewal
+certbot renew --dry-run
+```
+
+**Result:** Even though validation is disabled in APK, you have a proper certificate for users with patched/secure clients.
+
+---
+
+#### ✅ **Option 2: Self-Signed Certificate**
+
+**Pros:**
+- Free
+- Complete control
+- Works due to disabled validation
+
+**Cons:**
+- Not trusted by browsers
+- Won't work with fixed APK
+
+**Generation:**
+```bash
+# Generate self-signed cert
+openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
+
+# For ASP.NET Core
+dotnet dev-certs https --export-path cert.pfx --password YourPassword
+```
+
+**Result:** Works perfectly with current APK since validation is disabled.
+
+---
+
+#### ✅ **Option 3: HTTP Only (Development)**
+
+**Pros:**
+- Simplest setup
+- No certificate management
+- Fast testing
+
+**Cons:**
+- ⚠️ NO ENCRYPTION - traffic visible on network
+- Not recommended for production
+
+**When to Use:**
+- Local testing only
+- Isolated networks
+- Development environments
+
+---
+
+### For Security-Conscious Users
+
+#### 🔒 **Option 1: Fix the APK (Advanced)**
+
+**Changes Needed:**
+
+1. **Enable SSL Validation in CloudcellTrustManager:**
+```smali
+# In CloudcellTrustManager.smali
+# Change: m_bSSLCheck = false
+# To:     m_bSSLCheck = true
+
+.field private m_bSSLCheck:Z
+
+.method public constructor <init>(...)
+    # ...
+    const/4 v0, 0x1  # Change 0x0 to 0x1 (true)
+    iput-boolean v0, p0, Lcom/firemonkeys/cloudcellapi/CloudcellTrustManager;->m_bSSLCheck:Z
+```
+
+2. **Implement Proper TrustManager in Http.java:**
+```smali
+# Replace Http$1.smali checkServerTrusted with:
+.method public checkServerTrusted([Ljava/security/cert/X509Certificate;Ljava/lang/String;)V
+    .locals 2
+    
+    # Get default TrustManagerFactory
+    invoke-static {}, Ljavax/net/ssl/TrustManagerFactory;->getDefaultAlgorithm()Ljava/lang/String;
+    move-result-object v0
+    invoke-static {v0}, Ljavax/net/ssl/TrustManagerFactory;->getInstance(Ljava/lang/String;)
+    
+    # Delegate to system trust manager
+    invoke-virtual {v0, p1, p2}, Ljavax/net/ssl/X509TrustManager;->checkServerTrusted(...)
+    return-void
+.end method
+```
+
+3. **Use Proper HostnameVerifier:**
+```smali
+# In HttpRequest.smali and Http.smali
+# Change: SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
+# To:     HttpsURLConnection.getDefaultHostnameVerifier()
+
+invoke-static {}, Ljavax/net/ssl/HttpsURLConnection;->getDefaultHostnameVerifier()
+move-result-object v0
+invoke-static {v0}, Ljavax/net/ssl/HttpsURLConnection;->setDefaultHostnameVerifier(...)
+```
+
+**Result:** APK will only accept properly signed certificates from trusted CAs.
+
+---
+
+#### 🔒 **Option 2: Use VPN**
+
+**Recommendation:**
+- Connect through trusted VPN when using community servers
+- Prevents local network MITM attacks
+- Encrypts all traffic to VPN endpoint
+

+
+## 🎮 For Community Server Users: What You Need to Know
+
+### ✅ **Is My Data Encrypted?**
+
+**YES** - Data is encrypted using TLS/SSL during transmission. Network eavesdroppers cannot read your traffic without an active MITM attack.
+
+### ⚠️ **Am I Safe from MITM Attacks?**
+
+**NO** - The game accepts any SSL certificate, including fake ones. If an attacker intercepts your connection, they can read all game data.
+
+**Risk Level by Network:**
+- 🟢 **Home WiFi (Secure):** LOW risk - attacker needs access to your router
+- 🟡 **Public WiFi (Coffee Shop):** MEDIUM risk - easier to attack
+- 🟡 **Corporate Network:** MEDIUM risk - IT admins can intercept
+- 🟡 **Hotel WiFi:** MEDIUM risk - shared infrastructure
+
+### 🛡️ **How to Protect Myself?**
+
+1. **Use Trusted Networks:** Play on home WiFi only
+2. **Use VPN:** Encrypts traffic before it reaches network
+3. **Trust Server Operator:** Choose reputable community servers
+4. **Check Certificate:** Use browser to verify server's SSL certificate
+5. **Wait for Secure APK:** Community may release hardened version
+
+### 📱 **Should I Be Worried?**
+
+**For Most Users: NO**
+
+**Why:**
+- Game data isn't sensitive (no passwords, credit cards, etc.)
+- Synergy ID is just a game identifier
+- Progress data is game-related only
+- EA has already shut down official servers (no real-money IAP)
+
+**When to Worry:**
+- Using public/untrusted WiFi frequently
+- Server operators are unknown
+- Suspicious network activity
+
+**Overall Assessment:** Low real-world risk for a discontinued mobile game with community servers.

+## 🔬 Technical Deep Dive
+
+### SSL/TLS Implementation Details
+
+#### **TLS Version Support**
+
+```smali
+# From HttpRequest.smali
+const-string v3, "TLS"
+invoke-static {v3}, Ljavax/net/ssl/SSLContext;->getInstance(Ljava/lang/String;)
+```
+
+**Supported Versions:**
+- TLS 1.0 ✅
+- TLS 1.1 ✅
+- TLS 1.2 ✅
+- TLS 1.3 ✅ (Android 10+)
+
+**Note:** "TLS" protocol string enables highest version supported by Android OS.
+
+---
+
+#### **Cipher Suites**
+
+**Default:** Uses Android system default cipher suites (not customized)
+
+**Typical Suites (Android 8+):**
+- `TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256`
+- `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256`
+- `TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384`
+- `TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384`
+
+**Security:** Strong cipher suites with forward secrecy (ECDHE) and AEAD encryption (GCM).
+
+---
+
+#### **TrustManager Chain**
+
+```java
+// Custom trust manager bypasses default validation
+TrustManager[] trustManagers = new TrustManager[]{
+    new CloudcellTrustManager(this)  // Custom, validation disabled
+};
+
+SSLContext sslContext = SSLContext.getInstance("TLS");
+sslContext.init(null, trustManagers, new SecureRandom());
+
+HttpsURLConnection.setDefaultSSLSocketFactory(
+    new TLSSocketFactory(sslContext.getSocketFactory())
+);
+```
+
+**Flow:**
+1. TLS handshake initiated
+2. Server presents certificate
+3. `CloudcellTrustManager.checkServerTrusted()` called
+4. Method checks `m_bSSLCheck` flag → **false**
+5. Returns immediately without validation
+6. Connection accepted
+

+| **CloudcellTrustManager** | `smali_classes2/com/firemonkeys/cloudcellapi/CloudcellTrustManager.smali` | 56-76 |
+| **Empty TrustManager** | `smali_classes2/com/firemint/realracing/Http$1.smali` | 38-42 |
+| **ALLOW_ALL_HOSTNAME_VERIFIER** | `smali_classes2/com/firemonkeys/cloudcellapi/HttpRequest.smali` | 111 |
+| **ALLOW_ALL_HOSTNAME_VERIFIER** | `smali_classes2/com/firemint/realracing/Http.smali` | 179-181 |
+| **SSL Flag (m_bSSLCheck)** | `smali_classes2/com/firemonkeys/cloudcellapi/CloudcellTrustManager.smali` | 24 |

+## 📝 Summary & Conclusion
+
+### ✅ **What's Good**
+
+1. **TLS/SSL encryption is enabled** - Data is encrypted in transit
+2. **Strong cipher suites** - Modern encryption algorithms used
+3. **No certificate pinning** - Allows community servers flexibility
+4. **Accepts self-signed certificates** - Easy local testing
+
+### ❌ **What's Bad**
+
+1. **Certificate validation disabled** - Accepts invalid/expired certificates
+2. **Hostname verification disabled** - Accepts certificates for wrong domains
+3. **Empty TrustManager** - Zero validation in Http.java implementation
+4. **MITM vulnerability** - Attackers can intercept traffic on compromised networks
+
+### 🎯 **Bottom Line**
+
+**For Community Server Project:**
+This is actually **beneficial** - you can use self-signed certificates or Let's Encrypt without any issues. The disabled validation means:
+- ✅ Easy setup with any SSL certificate
+- ✅ Works with localhost, 10.0.2.2, custom domains
+- ✅ No need for expensive certificates
+- ✅ Quick development/testing
+
+**For Security:**
+Yes, there are vulnerabilities, but the real-world risk is **low** for a discontinued mobile game. Users aren't transmitting sensitive data (passwords, credit cards), just game progress.
+
+**Recommendation:**
+- Use Let's Encrypt for production servers (free, proper certificates)
+- Document the security tradeoffs for users
+- Consider releasing a "hardened" APK variant for security-conscious users
+- Add SSL certificate verification toggle in settings (let users choose)
