These terms apply to CheepDoku (Korean title: 삐약도쿠, Japanese title: PiyoDoku), a logic puzzle game for Android and iOS made by WaveWorks ("we"). By using the game you agree to these terms. If a Korean and an English sentence differ, the Korean version applies.
1. The game
You place one chick in every row, column, and region so that no two chicks touch. The game works offline and without an account. Your progress, settings, items, and purchase status are saved on your device.
2. Use
- You may use the game for personal, non-commercial purposes.
- You must not modify game files or data, manipulate scores or rankings with automated tools, or reverse-engineer and redistribute the game.
3. Sign-in, ranking, and profile
This section applies to versions of the game that offer sign-in. Versions without sign-in do not save data to our server and do not offer the ranking, profile, or Chick Club.
- Sign-in is optional. On Android you sign in with Google Play Games, on iOS with Sign in with Apple. Everything else in the game works without signing in.
- When you sign in, your progress is saved to our server and you can join the weekly ranking. The ranking shows your nickname, avatar, and weekly score. If you change devices or reinstall the app, you can sign in to load the progress saved on our server.
- The Chick Club (Gold) membership is free. Signed-in players can join after clearing the daily puzzle 7 days in a row. Membership lasts 30 days and gives sign-in rewards and Gold-only profile items.
- Nicknames and mottos must not contain profanity, hate speech, impersonation of others, or personal information. We filter some words automatically. If a nickname breaks this rule, we may reset it or remove your ranking entry.
- If we find manipulated scores, we may remove the scores and limit your access to the ranking.
- You can delete your account in Settings at any time. Deleting your account removes your saved progress, profile, and ranking entries from our server. Weekly score distribution totals that cannot identify you remain.
4. Items and paid products
- Magnifiers and hints are in-game items. They can be used only in the game and cannot be exchanged for money or transferred.
- Paid products are the Starter Pack, permanent Remove Ads, 1-week and 1-day Remove Ads passes, and magnifier and hint packs. Prices are shown in the store and on the purchase screen.
- Remove Ads removes interstitial and banner ads. Rewarded ads that you choose to watch for a reward remain available.
- The Starter Pack and permanent Remove Ads are tied to your store account and can be restored with [Restore Purchases] in the shop. Timed passes and consumable items are stored on your device. If you delete the app or change devices, items you have not used and the remaining time on a pass may not be recovered.
5. Ads
The game shows interstitial and banner ads, and rewarded ads that you choose to watch. You receive a reward after the rewarded ad finishes. If the ad fails to load or ends early, you may not receive the reward. Ad content depends on the ad network.
6. Refunds
- Refunds follow the policy and procedure of the store where you bought the product (Google Play or the App Store). We do not process store payments ourselves.
- Under Article 17(2) of the Korean Act on Consumer Protection in Electronic Commerce, digital products that were delivered right away and have been used may not be eligible for withdrawal. The shop shows this notice before purchase.
- For unused products, payment errors, or duplicate charges, request a refund through the store. Contact us by email if you need help.
7. Data and liability
Data saved only on your device can be lost if you delete the app, change devices, or reset storage, and we cannot recover it. We are not liable for data loss on your device unless it was caused by our intent or gross negligence.
8. Changes and termination
We may change the game or end the service. We will announce the end of the service at least 30 days in advance on the store page or in the game. We will announce changes to these terms at least 7 days before they take effect, or at least 30 days before for changes unfavorable to you.
