This is a translation of the Japanese original. If there is any difference between the two, the Japanese version prevails.


Article 1 (Scope and Agreement)

  1. These Terms of Use (the "Terms") set out the conditions for using the smartphone and tablet application "Sea Angel: Relaxing Aquarium" (Japanese title: "クリオネ水槽") (the "App") provided by Miao Zhihao (trade name: Clione Aquarium Team) ("we," "us").
  2. Anyone who uses the App ("you") uses it after agreeing to all of these Terms. By using the App, you are deemed to have agreed to these Terms.
  3. These Terms are standard terms under Article 548-2 of the Civil Code of Japan and apply to all relationships between you and us regarding the use of the App.
  4. In addition to these Terms, the Licensed Application End User License Agreement set by Apple Inc. (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/) applies to your use of the App. That agreement prevails on matters concerning the rights and responsibilities of Apple Inc., and these Terms prevail on all other matters.
  5. Information is handled as described in our separate Privacy Policy, which forms part of these Terms.

Article 2 (Content and Changes)

  1. The App lets you watch clione (sea angels) swim in a tank. It is free to download, and many features can be used for free.
  2. Some dioramas, backgrounds, tank shapes, items, music, and so on are available through Clione Premium (Article 3) or by exchanging Star Medals (Article 4).
  3. We may change the content of the App at our discretion, including adding, changing, or replacing dioramas, backgrounds, music and other items, and changing its appearance or features.
  4. We may temporarily suspend all or part of the App without prior notice in any of the following cases:
    1. Maintenance, inspection, or updates of servers or other equipment
    2. When providing the App becomes difficult due to fire, power outage, natural disaster, network failure, or other force majeure
    3. Failures or specification changes in services of external providers such as Apple Inc., Google LLC, RevenueCat, Inc., and Cloudflare, Inc.
    4. Any other case in which we judge suspension to be necessary
  5. We may end the App after giving notice in the App or on the page where these Terms are posted at least 30 days in advance.

Article 3 (Clione Premium)

  1. Clione Premium ("Premium") is an auto-renewing subscription on the App Store. While subscribed, you can use all dioramas, backgrounds, tank shapes, and items in the App, the Premium-only music, and a higher limit on the number of clione. Newly added dioramas are available from the day they are released.
  2. Premium is available as a yearly or monthly plan. The price, period, and any free trial are shown on the App Store screen before purchase.
  3. If there is a free trial, you will move to the paid period automatically when the trial ends and be charged.
  4. Premium renews automatically for the same period unless canceled at least 24 hours before the end of the current period. Payment is charged to your Apple Account.
  5. You can cancel (turn off auto-renewal) anytime from your device's Settings > your name > Subscriptions. After canceling, you can use Premium until the end of the current period. No pro-rated refund is given for the remainder of a period canceled midway. Deleting the App does not cancel the subscription.
  6. Apple Inc. handles billing and refunds, and whether a refund is given is decided by Apple Inc. under its own rules. We do not issue refunds.
  7. After changing devices or reinstalling, you can use Premium again by tapping "Restore Purchases" with the same Apple Account used for the purchase.
  8. Items exchanged for Star Medals under Article 4 remain after Premium ends. Items available only with Premium can no longer be used.
  9. The items available with Premium may change under Article 2, Paragraph 3. We will give advance notice under Article 11 before any important change that is unfavorable to you.

Article 4 (Star Medals)

  1. Star Medals can be received for free in the App by picking them up at the bottom of the tank or by choosing to watch an ad (Article 5). Star Medals cannot be purchased for money.
  2. Star Medals can be used only to exchange for dioramas, backgrounds, tank shapes, items, and so on that we specify within the App.
  3. Star Medals have no monetary value. Star Medals and items exchanged for them are only a right to use them within the App and are not property. You may not convert them into money, transfer, lend, or pledge them to others, or trade them outside the App.
  4. We may change the number of Star Medals you can receive per day, the number required for exchanges, and the range of items available. Items you have already exchanged remain usable as long as the App is provided.
  5. If a different number of Star Medals or items than intended is recorded because of a bug in the App or server, a communication error, or the like, we may correct the record.
  6. Your Star Medal record is stored on our server, linked to the identifier described in the Privacy Policy. On devices where the App was downloaded with the same Apple Account, Star Medals carry over after changing devices or reinstalling. They may not carry over on devices where App Store information cannot be obtained, or beyond the number of transfers we set.
  7. When the App ends, or when your record is deleted at your request under Article 13, Star Medals and items exchanged for them can no longer be used. Because Star Medals are received for free, no compensation is provided for them.

Article 5 (Ads)

  1. The App shows video ads (rewarded ads) only when you choose to watch one to receive Star Medals. The App never shows ads on its own.
  2. When you watch an ad to the end, you receive the number of Star Medals we specify. There is a daily limit. Ads may not be available depending on ad inventory and network conditions.
  3. The content of ads is decided by the ad provider (Google LLC), and we are not responsible for the content of ads or for products or services reached through them.

Article 6 (Prohibited Acts)

  2. If you suffer damage from our breach of obligation or tort caused by our slight negligence (negligence other than willful misconduct or gross negligence), our liability is limited to ordinary damage actually incurred by you (excluding damage arising from special circumstances, lost profits, and damage from loss of data), up to the amount you paid for the App in the one month before the damage occurred.
  3. The limitation in the preceding paragraph does not apply to damage caused by our willful misconduct or gross negligence.
