🔒 Security & Legal

⚠️ Important Disclaimers

This project is for:

  • ✅ Private/LAN gameplay
  • ✅ Game preservation
  • ✅ Educational purposes
  • ✅ Offline gaming

NOT for:

  • ❌ Piracy
  • ❌ Bypassing legitimate purchases
  • ❌ Cheating in official multiplayer
  • ❌ Commercial exploitation

Security Recommendations

For Server Operators:

  • Use HTTPS with valid certificates
  • Implement rate limiting
  • Enable authentication for public servers
  • Regular security updates
  • Monitor for abuse

For APK Distributors:

  • Clearly label as "community version"
  • Include source of server URL
  • Respect intellectual property
  • No bundled pirated content

🌟 Use Cases

1. Game Preservation

When EA shuts down official servers, community servers keep the game playable.

2. Private Servers

Friends/groups can host private servers for exclusive play.

3. Offline Play

Play without internet connection on local network.

4. Custom Content

Server operators can modify catalogs, events, rewards.

5. Educational

Learn about client-server architecture, protocol reverse engineering.

6. Development

Test and develop features without affecting official servers.
