Privacy Policy
Last updated: August 12, 2026 · applies to letterderby.com and the LetterDerby Discord app
Short version: LetterDerby has no accounts, sets no tracking cookies, and doesn't sell or share your data with data brokers. We store the minimum needed to run a multiplayer game.
What we store
- A random player ID in your browser's localStorage, plus the display name you choose. No email, no password, no real name required.
- Game data — rooms, guesses, scores, and chat messages — kept on our servers while a room is active and automatically deleted within 24 hours of inactivity. Leaderboard entries (display name + score) are kept up to their window (daily/monthly) plus the all-time board.
- If you launch us inside Discord, Discord shares your user ID, username, display name, and avatar with us (the identify scope) so your name auto-fills. We don't receive your email, messages, or server list.
- Aggregate counters — e.g. "rooms created today" — that contain no personal data, and privacy-friendly page analytics (Vercel Web Analytics) that use no cookies and no cross-site tracking.
Chat
Room chat is visible to everyone in the room, stored only while the room exists (max 24h of inactivity), and never used for anything else. Hosts can remove players from their rooms.
Who we share with
Infrastructure only: Vercel (hosting), Upstash (game database), and Discord (when you use the Discord app). Word definitions are looked up server-side, so dictionary providers never see who you are. If we ever add advertising, it will appear only outside of active rounds and this policy will be updated first.
Children
LetterDerby is a general-audience word game and is not directed at children under 13.
