Privacy Policy

Wave.io - Paint Battle · Last updated: November 3, 2026

This policy explains what information the game Wave.io - Paint Battle ("the game", "we") collects, why, and the choices you have. It applies to the iOS, Android and web versions of the game.

1. Information we collect

• Game account and progress. When you first open the game, an anonymous account is created for you automatically. Your game progress (level, coins, gems, skins, upgrades, purchases, rewards) and your nickname are saved to our cloud database so that they are not lost and can be restored on another device.
• Sign-in information (optional). If you choose to save your account with email, Sign in with Apple or Google Play Games, we receive your email address or an identifier from that service. Your password is handled by Google Firebase Authentication and is never visible to us.
• Usage and diagnostics. Anonymous gameplay events (for example level started or finished, ads watched, purchases attempted), device model, operating system, app version, approximate country and crash reports.
• Advertising data. The advertising identifier of your device (IDFA on iOS, Advertising ID on Android) and related device information, used by our advertising partner to show and measure ads. On iOS this is only used if you allow tracking.
• Purchases. In-app purchases are processed by Apple App Store or Google Play. We do not receive your payment card details; we only receive a confirmation of the purchase.

2. How we use information

• To run the game, save your progress and restore it on other devices.
• To understand how the game is played, balance difficulty and fix crashes and bugs.
• To show ads that keep the game free, and to deliver rewards when you choose to watch an ad.
• To verify purchases and deliver purchased items.
• To send notifications on your device (for example daily rewards), only if you allow them. You can turn them off in your device settings.

We do not sell your personal information.
