Earmonia

Terms of Use

Effective date: October 24, 2026

In shortEarmonia is free and has no ads. Outfit sets for Moni and ship decorations are optional purchases; they are cosmetic only and give no advantage in the game. Connecting an account is optional; with one you can see your friends' boats in the Harbor. Your name is visible to your friends there, and inappropriate names and behavior can be reported and blocked. Weekly contests are free and their rewards exist only in the game. Moni, the artwork, the sounds and the story belong to us.

1. Parties and acceptance

These Terms of Use govern the use of the Earmonia app and the earmonia.app website, developed by Recep Kaan Çağlar (the “Owner”). By downloading or using Earmonia you agree to these terms. For apps obtained through the App Store, Apple's Standard License Agreement (EULA) also applies and prevails where it conflicts with these terms. For apps obtained through Google Play, the Google Play Terms of Service also apply.

2. The service

Earmonia is a game that teaches ear training and music theory. The Owner may develop, change or remove parts of its content.

3. License

We grant you a non-transferable, non-exclusive license to use Earmonia for personal, non-commercial purposes on Apple and Android devices that you own or control.

4. Intellectual property

The Moni character and all artwork, music, sound effects, story and lesson content belong to Recep Kaan Çağlar. They may not be copied, modified or distributed without permission.

5. Account

  • The game works fully without an account. If you like, you can connect an account with Sign in with Apple on iPhone and iPad or Sign in with Google on Android, back up your progress and purchases, and move them to another device.
  • Your account is as secure as your Apple Account or Google account; keeping that account safe is your responsibility.
  • You can delete your account at any time under Profile › Account › Delete account; if you can't access the app, ask by email as described on the Delete account page. A deleted account's backup cannot be recovered; the game on your device and the purchases tied to your store account remain.
  • If you connect an account, your in-game name is shown in the Harbor to your friends and to captains you have a pending request with (see 6).

6. The Harbor and community rules

The Harbor is where players with an account add each other by friend code and see each other's boats, Deck cards and weekly stars. The Harbor has no chat and no free text; players can only send a preset greeting. The only written content others can see is your in-game name. When using the Harbor you agree to these rules:

  • Do not use names that are insulting, profane, sexual or hateful, that impersonate someone else, or that look official (for example “Earmonia”, “support”, “admin”).
  • Do not use your real full name, address, phone number or other personal details as your name; use a nickname.
  • Do not harass or abuse other players with requests or greetings.

Names are checked with a word filter; a name caught by the filter is not shown to others. You can report a captain with “Report” in the ⋯ menu on their Deck or on their request, and block them with “Block”; a blocked captain can no longer send you requests or find you. We review open reports within 24 hours. We may hide the name of a player who breaks these rules or remove them from the Harbor; their game and progress remain. See sections 2.3 and 2.4 of the Privacy Policy for details. You can also write to [email protected].

7. Contests

  • Players with an account can take part in weekly contests for free. Some contests require you to have reached a certain sea or to have finished it. Each contest's dates, daily number of questions and rewards are shown on its card.
  • One round is played each day and scored on our server; the weekly ranking is the total of the daily scores. On a tie, the player with the shorter total time ranks higher, and if that is also equal, the player who reached the score first.
  • Rewards exist only in the game (such as trophies, gold and outfit pieces) and are added to your account when the contest ends. They have no monetary value and cannot be sold or transferred; contests never award money or anything of monetary value.
  • The leaderboard shows your name, Moni's outfit, your boat and your trophies to all players; the name rules in section 6 apply here too.
  • Using cheating software, taking part with more than one account or sending false answers to our server is not allowed. We may remove entries that look like cheating from the leaderboard and withhold their rewards.
  • If there is a technical problem or an error, we may extend or cancel a contest or correct its results.

8. In-app purchases

  • Earmonia is free to download and play. There are no ads and no subscriptions.
  • Outfit sets for Moni, ship decoration sets, bundles with both, and the Captain's Chest with every set can be bought as one-time purchases. They are cosmetic only and have no effect on lessons, progress or scores.
  • Prices are shown before purchase in the store (App Store or Google Play) and in the app, in your country's currency. Payment is charged to your Apple Account on iPhone and iPad, and to your Google account through Google Play on Android.
  • Purchases are tied to your account with the store you bought them from and come back on other devices on that platform with the same account through “Restore purchases”. A set bought on the App Store does not unlock on Android, and one bought on Google Play does not unlock on iPhone or iPad. Purchases are not shared through Family Sharing or Google Play Family Library.
  • Bundles and the Captain's Chest are sold at full price even if you already own some of the sets they include, so check their contents before you buy.
  • Refund requests for App Store purchases are handled by Apple (reportaproblem.apple.com) under Apple's terms, and for Google Play purchases by Google Play under Google Play's refund policy. A refunded item is removed from the app.
  • In-game rewards such as gold and stars have no monetary value and cannot be sold or transferred.

9. Rules

  • Do not try to reverse engineer or modify the app, or play it with cheating software.
  • Do not try to send false data to our servers or disrupt the service.
  • Do not use the app for any unlawful purpose.

We may close accounts that break these rules or remove them from the Harbor or from contests.

10. Test builds

TestFlight and Google Play test versions are in development. They may contain bugs, features may change, and your progress may be reset. Purchases in TestFlight are for testing and are not charged. In Google Play test versions, purchases are real payments unless you have been added as a license tester.

11. Protect your hearing

When playing with headphones, keep the volume at a comfortable, moderate level.

12. Limitation of liability

Earmonia is provided “as is”. We cannot guarantee that it will run without interruption or errors, or that it will bring you to a particular level in music. To the extent permitted by law, we are not liable for indirect damages arising from use of the app or for data loss that occurs despite reasonable precautions. Your statutory consumer rights are not affected.

13. Changes

We may update these terms from time to time. The current version is always on this page, and we will announce important changes here.

14. Governing law

These terms are governed by the laws of the Republic of Türkiye. This does not affect any mandatory consumer protection rights you have under the law of the country where you live.
