Wallet address — your Solana public key, used as your game identity. This is a public blockchain address by nature.
Game state — your inventory, score, and crafted items, stored so your progress persists across sessions.
Transaction signatures — on-chain tx IDs for purchases, used to prevent replay attacks and to verify payments.
Session token — a random token stored in your browser's localStorage, used to keep you logged in for 24 hours.
We never collect: your name, email address, IP address (not stored, only used for rate limiting in memory), private keys, seed phrases, payment card details, or any personal identification information.
We do not use cookies. We do not run third-party analytics or advertising trackers.
Your wallet address and game state are used exclusively to run the game — saving progress, displaying the leaderboard, and processing prize payments. We do not sell, share, or monetise your data in any way.
Game data is stored in a Cloudflare D1 database (SQLite, hosted on Cloudflare's global edge network). Session tokens are stored in Cloudflare KV with a 24-hour expiry. Your browser stores the session token and wallet address in localStorage — this data never leaves your device except when communicating with our API.
Game state and leaderboard scores are retained for the current season plus 90 days. Purchase records (tx signatures) are retained indefinitely as blockchain proof. You may request deletion of your game state by contacting us — note that on-chain transaction records cannot be deleted as they exist on the public Solana blockchain.
We use the Solana public RPC (api.mainnet-beta.solana.com) to verify on-chain transactions. We use Helius RPC on our server-side only for reliable transaction verification. Neither service receives your game data — only public blockchain queries are made.
You can delete your session at any time by clearing your browser's localStorage. To request full deletion of your game data from our database, contact us with your wallet address.
