Privacy Policy

Last updated: September 15, 2026

1. General Principles & Data Controller

Lethalgames (accessible at https://lethalgames.eu) is dedicated to protecting player privacy. If you have any questions regarding data protection, please contact us at support@lethalgames.eu.

We adhere to the Privacy by Design standard. You can play all games entirely as a guest without an account. Guest sessions do not store personal identifiable information and we do not use third-party tracking cookies.

2. Information We Collect

  • Guest players: Temporary session tickets stored locally in your browser and the guest nickname you choose.
  • Registered players: When signing in via Google or Email, we process your user ID (UID), email address, display name, and avatar image. We also track game statistics, rating (ELO/Glicko-2), and completed match records.
  • Payments: All transactions are processed by our Merchant of Record, Paddle. Lethalgames never accesses or stores your credit card details.

3. Third-party Infrastructure

  • Cloudflare: Edge security, DDoS mitigation, and multiplayer realtime Workers.
  • Firebase: Secure authentication services.
  • Supabase (EU Region): Encrypted database hosting player profiles and rankings.

4. Lethal Card, Profile, Friends & Chat

  • Lethal Card & leaderboard: After games against people we record the result, the number of moves, your ELO rating (Glicko-2) and your nickname. A Reddit username is optional and not verified. Anyone with a card’s code can verify it; players with at least one counted game appear on the public leaderboard.
  • Secured profile & passkeys: Your profile name is public. For passkeys we store only the public key and credential ID — your fingerprint or face never leaves your device.
  • Trophies page: Public; it shows your profile name, rating, results and the nicknames of opponents you played.
  • Friends & chat: We store your friends list, requests, blocks and messages (text and game invites). Only the two people in a conversation can see its messages, and friends can see whether you are online. Messages are deleted when either of you removes the other as a friend, or when you delete your profile.
  • Notifications: If you turn notifications on, we store the subscription address from your browser’s push service (for example Apple, Google or Mozilla) and the encryption keys. A notification contains your friend’s name and the start of the message and is sent encrypted through that service. Turning notifications off or deleting your profile removes the subscription.
  • Data in your browser: Local storage keeps your nickname, Reddit username, guest token and settings. These are not tracking cookies.
  • Deletion: You can delete your profile yourself at any time on the My trophies page: your passkeys, profile name, Reddit username, friends and all messages are removed. Results of games you played stay in opponents’ history as “Deleted player”.

5. Your Rights Under GDPR

You can delete your Lethal Card profile, friends and messages yourself on the My trophies page. You also have the right to access, rectify, port, or request complete deletion of your account and personal data at any time. Simply contact us at support@lethalgames.eu.
