Privacy Policy
Hollow War is designed with privacy in mind. We do not require you to create an account or provide any personal information to play. No name, email address, or payment data is ever collected.
1. Who We Are
Hollow War is developed and published by MB Anithesis, a company registered in Lithuania. If you have any questions about this Privacy Policy, you can contact us at:
2. Information We Collect
We collect only the minimum data necessary to provide core game features:
- Device identifier (UUID): A randomly generated anonymous identifier created on your device the first time you launch the game. This ID is not linked to your name, email, or any account. It is used to associate your game progress with multiplayer features such as guilds and the global leaderboard.
- Game progress data: Your chimera collection, story progress, arena rank, and related gameplay state. This data is stored locally on your device using your browser's localStorage and, where applicable, synced to our backend (Supabase) tied to your anonymous device UUID.
- Guild and leaderboard data: If you join a guild or participate in the arena leaderboard, your chosen display name (set by you in-game) and arena rank are stored on our servers to enable these features.
- Guild chat messages: Messages you send in guild chat are stored on our servers and visible to other members of your guild.
3. Information We Do Not Collect
- Your real name, email address, or any contact information
- Payment or financial information of any kind
- Precise location data
- Your contacts, camera, or microphone
- Any data from other apps on your device
4. How We Use Your Data
The data we collect is used solely to operate the game:
- To save and restore your game progress across sessions
- To display the global arena leaderboard
- To enable guild membership and real-time guild chat
- To prevent abuse of multiplayer features
We do not use your data for advertising, profiling, or any purpose outside of operating the game.
5. Third-Party Services
Hollow War uses the following third-party services to operate:
- Supabase (supabase.com) — Backend database and real-time services. Your anonymous device UUID, display name, arena rank, and guild data are stored on Supabase servers. Supabase is GDPR compliant. See their privacy policy at supabase.com/privacy.
