Privacy Policy

Wallet address and optional display name from World wallet authentication.

World ID verification status (proof that you are a unique human — we do not receive your biometric data).

Game progress: Emeralds, Diamonds, upgrades, cosmetics, migration stats, and settings stored locally and in cloud save.

Leaderboard entries: username, wallet address or pseudonym, and sanitized score (Golden Wings).

Purchase references and transaction IDs to verify Diamond Chest payments and prevent double crediting.

Technical data: language preference, basic device/browser info in server logs (via hosting provider).

Run gameplay, cloud sync, leaderboards, referrals, and on-chain reward distribution.

Verify in-app purchases and prevent fraud or duplicate credits.

Send optional push notifications if you opt in (World notifications API).

Improve stability and fix bugs.

Leaderboard usernames and scores are visible to other players.

We use infrastructure providers (e.g. Vercel hosting, Upstash Redis for saves/leaderboard) under their privacy terms.

On-chain transactions are public on World Chain by nature.

We do not sell your personal data.

Saves and leaderboard data are kept while the service operates or until you request deletion.

We use reasonable technical measures; no system is 100% secure.

You can play without cloud features in some environments; full features require wallet sign-in.

Clear local data via browser settings; contact us to request removal of cloud save or leaderboard entries tied to your wallet.

Privacy requests: support@rcol.fun

The game is not directed at children under 13 (or the minimum age in your region). If you believe a child provided data, contact us.

We may update this Policy. The “last updated” date will change accordingly.
