Terms of Use

Last updated: October 14, 2026

These Terms of Use (the "Terms") set out the conditions for using the iOS application "Charge, Barrier, Attack" (Japanese name: 溜め・バリア・攻撃; shown on the Home Screen as "Clap Duel" on English devices and "溜めバリア攻撃" on Japanese devices; the "App"), provided by the individual developer Rinblog (the "Developer"). By using the App, you are deemed to have agreed to these Terms.

1. What the App is

The App turns a hand game that was popular in Japan's Heisei era during lunch and other breaks (two players clap twice, then play "Charge", "Barrier" or "Attack" at the same time) into a 3D battle game. It offers the following.

• Solo: Practice (4 opponents who wait until you choose a move), vs CPU (8 opponents; the tempo starts at 60 BPM and goes up by 20, reaching 180 with the 7th; clear the 1st to 7th to face the 8th at 200 BPM), and Custom (you set the opponent's moves, the tempo and the pace; the tempo is 60 to 180 BPM, and 200 becomes available once you clear the 8th in vs CPU)
• Online matches: Casual (you choose a BPM range, 80–100, 120–140, 160–180 or 200, and play someone in the same range) and Friends (creating a room shows a 4-digit room number, and your friend enters it to join the same room; the person who creates the room chooses the tempo from 60 to 180 BPM, and 200 once they have cleared the 8th in vs CPU)
• Moves and looks: you can choose the set of moves you use (Charge, which you always have, plus 3 of 5: Barrier and the Lv1 to Lv4 Attacks), your character (the stick figure and characters you have bought), the color of the stick figure (12 colors), and the move effects

Ranked (matches in which points go up or down with wins and losses) is being prepared and cannot be selected in the App yet. When we start offering it, its rules will be posted in these Terms and in the App.

"Cleared" marks, results and other records in the App only have meaning inside the App. They have no property value and cannot be exchanged for money.

2. Pricing and purchases

• The App is free to play. Solo play and online matches (Casual and Friends) are all free. The stick figure with its 12 colors and the standard look of the moves can be used by everyone for free.
• The paid items are the following, each bought once in the App (all are non-consumable and last for good once bought). The purchase screens can be opened from "Shop" in the Moves tab, from "Purchases" in Settings, and other places. Strength in a match and the opponent's strength are the same whether or not you buy anything.
• "Remove Ads": no ads are shown in the App (neither the banner ad at the top of the menu screens nor the full-screen ads between matches).
• Characters, one at a time: you can buy each of the 12 Tekage characters one at a time, and choose a character you bought as your own character (looks only).
• "Everything Set": the 12 Tekage characters plus "Remove Ads". Move effects and characters added later are not included (they can be bought separately). If you have already bought part of it and buying the rest separately would cost the same or less, the set is not shown.
• "Tekage Set": the 12 Tekage characters ("Remove Ads" is not included). If you have already bought some of them and buying the rest separately would cost the same or less, the set is not shown.
• Move effect "Tekage Effects": when chosen, all 6 moves (Charge, Barrier and Lv1 to Lv4) turn into hand-shadow moves (Lv1 fires one hand and Lv2 both hands toward the opponent, and Lv3 is a giant shadow; looks only). Usable with any character. It is separate from characters and is not included in the "Everything Set".
• In Japan the prices are 480 yen for "Remove Ads", 160 yen for one character, 1,480 yen for the "Everything Set", 1,280 yen for the "Tekage Set" and 240 yen for the move effect "Tekage Effects" (all tax included). In other countries and regions it is the amount shown on the purchase screen.
• Payment is charged once to the payment method on your Apple ID when you confirm the purchase. You are not charged again after that. What you buy is available as soon as the purchase is confirmed.
• When you change devices or reinstall the App, you can get your purchases back at no extra cost with "Restore purchases" on the Shop screen, the "Remove Ads" screen or "Purchases" in Settings, using the same Apple ID.
• Because these are digital items, they cannot be returned or canceled after purchase. Refunds follow Apple's policy. Please request them from Apple (reportaproblem.apple.com).
• We may add characters or move effects in the future. When we do, their content and price will be shown in the Shop and on the purchase screen, and posted in these Terms and the legal notice (Japan).

3. Online matches

• The App signs you in with an anonymous ID when it starts. In online matches, the player name you choose (up to 12 characters), your character, your stick-figure color and your chosen move slots are shown on your opponent's screen. Please do not use a real name, contact details or inappropriate words. A name containing words that cannot be used (words that impersonate others or inappropriate words) is replaced with "Player" followed by a number.
• If an opponent has an inappropriate name, please let us know with "Report" on the match screen. You will not be matched with a reported opponent in Casual again, and their name will be shown as "Player".
• Casual and Friends matches do not change points.
• If you close the App, send it to the background, or stop the match with "Quit" during a match, it counts as a loss.
• Depending on your connection, a move may not arrive in time. A move that does not arrive in time is treated as "Charge". If your moves keep failing to arrive because the connection is lost (5 turns in a row, or about 6 seconds' worth at fast tempos), it counts as a loss.
• A Friends room closes if no friend joins within 10 minutes.
• Match rooms and records of moves are deleted when a match ends (details are in the Privacy Policy).

4. Prohibited conduct

The following are prohibited when using the App.

• Modifying, analyzing or improperly manipulating the App or its communication (including learning an opponent's move in advance, rewriting records, or getting around ads or purchase restrictions).
• Using programs that play automatically, or putting an excessive load on the server.
• Manipulating match results or records unfairly (including using several devices or accounts to play yourself, losing on purpose to let an opponent win, or arranging results together). Once Ranked is offered, this also applies to rank points.
• Harassing other users, impersonating others, acting against laws or public order and morals, or using an inappropriate player name.
• Exchanging, buying, selling, brokering or soliciting accounts, records in the App or purchased items in return for cash, valuables, electronic money or items in other games.
• Disassembling or decompiling the App (except to the extent permitted by law).

If any of these is found, we may, without prior notice, suspend your use of online matches or take other measures.

5. Ads

For users who have not bought "Remove Ads" (or the "Everything Set"), we show a banner ad at the top of the menu screens, full-screen ads between matches (at most once every 3 matches, with 3 minutes between ads). No ad is shown on the match screen, and no full-screen ad is shown right after launch. Ads are served under the advertisers' responsibility, and the Developer does not guarantee their content.

6. Age

The App is not mainly directed to children under 13. If you are under 13, please use it with a parent's consent. If you are a minor, please get a parent's consent before buying.

7. Data and your account

• The App does not require an email address or phone number. It signs you in with an anonymous ID when it starts.
• Settings, results, your chosen looks and similar data are stored on your device. Carrying them over to a new device is not supported. If you delete the App or erase your device, the records on the device cannot be recovered. Purchased items can be recovered with "Restore purchases".
• If you want your data deleted, please ask at the email address given in the Privacy Policy (the contact on the Support page). We will delete the information about you on the server that we can identify from your request.
• Details of how data is handled are in the Privacy Policy.

8. Intellectual property

All rights in the App and in the screen designs, text, sounds and characters it produces belong to the Developer. Users are granted only the right to use the App for personal purposes.

9. Disclaimer

• The App is provided as is. The Developer does not guarantee that the App will run without interruption or be free of errors.
• The Developer is not liable for damage caused by communication problems, device failure or loss, or failures of third-party services (Apple, Google, RevenueCat and others), except in cases of the Developer's intent or gross negligence.
• The Developer is not in a position to mediate disputes between users and is not liable for them.

10. Changes to, or discontinuation of, the App

The Developer may change the App or stop providing it. When it ends, we will notify you in the App or on the support page in advance wherever possible. After it ends, features that use the server, such as online matches, can no longer be used.

11. Changes to these Terms

The Developer may change these Terms. The revised text will be posted on this page and in the App and takes effect from the time of posting. For important changes we will also notify you in the App.

12. Governing law and jurisdiction

These Terms are governed by Japanese law. If a dispute arises about the App, the Japanese court having jurisdiction over the Developer's address is the exclusive court of first instance by agreement.
