Privacy Policy

Krool World Last updated: November 10, 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.

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

1. Information We Collect

The Game has no sign-in. It does not ask for your name, email address, or phone number.

1.1 Your player record

The first time the Game reaches our server it creates an anonymous player record for your install. No action from you is needed. The record holds:

Device ID - a random identifier the Game generates and stores on your device. It is not your Apple ID, advertising ID, or any hardware identifier.
Player ID and friend code - generated by our server. The friend code is what you share to add friends.
Display name - generated by the Game from a word list. You can roll a new one. You cannot type your own.
Avatar - the icon you pick from the Game’s built-in set.
Timestamps - when the record was created and when you last connected.

1.2 Game progress and scores

Progress - level results, stars, high scores, gems, and lives are saved on your device. After each level you win, a copy is uploaded to our server so it can be restored on a reinstall.
Scores - your best score and stars per level are uploaded and used to build the leaderboards.

1.3 Leaderboards and friends

Leaderboards - weekly and all-time boards show your display name, avatar, total score, and total stars to other players.
Friends - if you add a friend by friend code, we store the connection. Friends can see your display name, avatar, friend code, when you last connected, and your highest unlocked level.

1.4 Usage and error events

The Game sends gameplay events to our own server: session start, level start, level complete or fail, hand types resolved, specials created and used, boosters used, continue offers, and reshuffles. If the Game hits an error it sends the error message, source file and line, and a short stack trace.

Each event carries a timestamp and the Game version, and is stored with your player ID. Events do not include your name, email, or contacts. There is no setting to turn this off. We use no third-party analytics or crash-reporting SDK.

1.5 IP address

Our server sees your IP address when the Game connects, as any server does. It is used for rate limiting and kept for about a minute for that purpose. Our hosting provider may keep its own standard logs.

1.6 Purchases

In-app purchases are processed by Apple. The purchase is confirmed on your device through Apple’s StoreKit. We do not receive your payment card details, and our server does not receive or store a purchase receipt.

1.7 Notifications

If you allow notifications, the Game schedules reminders on your device (lives refilled, daily reward). They are local notifications. No push token is collected and nothing is sent to a notification service.

1.8 Information we do NOT collect

No real name, email address, phone number, or password.
No precise location, contacts, photos, microphone, or camera data.
No advertising SDKs and no third-party ads. No advertising identifier (IDFA) is collected.
The Game is not directed at children under 13 and we do not knowingly collect personal information from children.

2. How We Use Information

We use collected information to:

Save and restore your game progress
Run the leaderboards and the friends list
Find and fix errors
Balance difficulty and content using gameplay events
Limit abuse of our server
Respond to support requests

We do not sell your personal information.

Service	Purpose	Data involved
Cloudflare	Hosts our server and database	Player record, progress, scores, friends, usage and error events, IP address
Apple	Processes in-app purchases	Handled by Apple under its own privacy policy

Other players see the leaderboard and friend details listed in section 1.3.

We do not share data with data brokers or advertising platforms. We may disclose information if required by law, subpoena, or court order.

4. Data Retention

Player record, progress, scores, and friends are kept until you ask us to delete them. Removing a friend deletes the connection on both sides.
Leaderboards are rebuilt from stored scores every 15 minutes.
Usage and error events are kept by our hosting provider for up to three months.
Session tokens expire after 30 days.
Data on your device is removed when you uninstall the Game.

5. Deleting Your Data

Uninstalling the Game removes the data on your device. It does not remove your player record from our server, and the Game has no delete button.

To have your server data deleted, email kroolworld@proton.me with your friend code (shown on the Friends screen). We will delete your player record, progress, scores, and friend connections within 30 days.

6. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, delete, or export the personal data we hold about you. To exercise any of these rights, contact us at kroolworld@proton.me with your friend code. We will respond within 30 days.

You can turn the Game’s notifications off at any time in your device settings.

California residents (CCPA)

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.

Our legal basis for processing is legitimate interest (improving the Game) and contract performance (providing the Game service). You may lodge a complaint with your local data protection authority.

7. Data Security

Data is sent over HTTPS and access to our infrastructure is restricted. No system is 100% secure; we cannot guarantee absolute security.

8. Changes to This Policy

We may update this policy from time to time. We will post the updated policy on this page and update the “Last updated” date.
