Privacy Policy

Krool World Last updated: April 11, 2026

This privacy policy describes how Krool World (“we”, “us”, “our”) collects, uses, and shares information when you use our mobile game Combo Ace (the “Game”) on iOS, Android, or web.

By using the Game you agree to this policy. If you do not agree, please uninstall the Game.

1. Information We Collect

1.1 Information you provide

Account information — If you sign in (e.g. Sign in with Apple, Google Sign-In), we receive your display name and a platform-specific user identifier. We do not receive or store your password.
Display name — If you set a display name for leaderboards or social features, it is stored with your account and visible to other players.
Friends and social connections — If you add friends (via invite link, Game Center, or Google Play Games), we store your friends list to enable social features such as sending and receiving lives, viewing friends’ progress, and friend leaderboards.
Support requests — If you contact us, we retain the correspondence to resolve your issue.

1.2 Information collected automatically

Game progress — Level completions, scores, star ratings, currency balances, settings, and tutorial state. This data is stored locally on your device and may be synced to our servers if you create an account.
Analytics events — Gameplay actions such as level starts, completions, failures, hand types resolved, boosters used, and purchase events. Events include a timestamp and session identifier but do not include your name, email, or device identifiers.
Crash and performance data — If the Game encounters an error, we may collect a crash report containing the error message, stack trace, device model, OS version, and Game version. No personal data is included.
Device information — Device type, operating system version, screen resolution, and preferred language. We use this for compatibility and localization.
Purchase receipts — When you make an in-app purchase, the platform (Apple App Store or Google Play) processes payment. We receive a transaction receipt for verification but never see your payment card details.
Leaderboard and ranking data — Scores, star counts, and level progress used to rank you on global and friend leaderboards. This data is associated with your display name and is visible to other players.

1.3 Information we do NOT collect

We do not collect your precise location, contacts, photos, microphone, or camera data.
We do not use advertising SDKs or serve third-party ads. No advertising identifiers (IDFA/GAID) are collected.

Leaderboard entries are retained for the duration of the leaderboard period (weekly, all-time, etc.) and may persist in aggregated form after your account is deleted.
Analytics and crash data is retained for up to 12 months, then deleted or aggregated.

We do not sell personal information. You may request disclosure of the categories and specific pieces of data we have collected. Contact us at the email above.
