This is an English translation for convenience. The Korean version is the official text, and it prevails if the two differ.

Article 1 (Purpose and scope)

  1. These Terms set the conditions for using the trial, paid license purchases, license keys, and notes sync service related to MyIdol (the "App"), a Windows program provided by AYH Labs (the "Operator").
  2. Conditions of using the App itself (prohibition of copying and reverse engineering, intellectual property, third-party software, etc.) follow the End User License Agreement (EULA) distributed with the App. If these Terms and the EULA differ, these Terms prevail for matters of purchase, trial, license keys, notes sync, and refunds, and the EULA prevails for other software use conditions.
  3. Matters not set out in these Terms follow applicable laws, including the Korean Act on the Regulation of Terms and Conditions and the Act on Consumer Protection in Electronic Commerce.

Article 2 (Definitions)

  1. Trial: the state of the App that can be used without payment for 7 days from the day it is first run
  2. Paid license: the right, obtained by payment, to keep using all features of the App after the trial period
  3. License key: the string that confirms a paid license
  4. Notes sync: an optional add-on feature, turned on by the user, that encrypts notes and syncs them between PCs
  5. Connection code: the per-user code used for notes sync
  6. User: a person who agrees to these Terms and installs or uses the App

Article 3 (Effect and changes of the Terms)

  1. You are deemed to agree to these Terms when you install, use, or purchase the App. When you purchase, these Terms and the refund policy are shown on the checkout screen.
  2. The Operator may change these Terms within the limits of applicable law. Changes, with their effective date and reason, are announced on the website 7 days before they take effect. Changes that are unfavorable or significant to users are announced 30 days in advance and also through an in-app notice.
  3. If you do not agree to the changed Terms, you may stop using and uninstall the App. Orders paid before a change are governed by the Terms and refund policy in effect at the time of payment.

Article 4 (Trial)

  1. You can use the App as a trial for 7 days from the day you first run it.
  2. The trial start time is the earlier of the times recorded in the save file and in the Windows registry. You must not change save files, the registry, or the system clock to extend or repeat the trial.
  3. When the trial ends, character change effects and records, and notes sync stop. To-dos, calendar, reminders, and notes on this PC keep working after the trial ends.
  4. The trial is meant to let you examine the App thoroughly before purchasing.

Article 5 (Purchasing a paid license)

  1. A paid license is purchased by paying on the website's purchase page. It is a one-time payment, and is not renewed or charged again automatically.
  2. Payment and tax processing are handled by the payment provider Lemon Squeezy, and the price, currency, and taxes are shown on the checkout screen.
  3. When payment is complete, the license key is sent to the email address entered at checkout. Any disadvantage from entering a wrong email address is borne by the user, but the Operator will resend the key if the order can be confirmed.
  4. A paid license includes, at no additional cost, App updates released after the time of purchase. This does not include anything the Operator has announced as a separate product.
  5. Before purchasing, please be sure to confirm with the trial that the App suits your environment and needs.

Article 6 (License keys)

  1. A license key is issued to one user, who may install and use the App on devices they own or control.
  2. You must not transfer, lend, sell, share, or publicly post the key. If a key is found to have been made public, the Operator may refuse to accept that key in App versions released afterwards.
  3. Nature of offline keys: keys are verified by checking a signature inside the App, with no communication with the Operator's servers. Therefore the Operator cannot remotely revoke or deactivate a key once it has been issued. Because of this, refunds may be limited in some cases; details follow the refund policy.
  4. You must keep your key safe. If you lose it, we will resend it where the order can be confirmed. If a key leaks through the user's carelessness, the Operator cannot revoke it.
  5. You must not bypass or disable the license check, or create or distribute tools that generate keys.

Article 7 (Withdrawal and refunds)

  1. Once a license key has been issued and supply of the digital content has begun, withdrawal of the order for a simple change of mind is limited. The Operator announces this in advance on the checkout screen and in the refund policy, and provides a 7-day trial.
  2. However, refunds are given where the key was not delivered or does not work properly, where the product differs from its description or advertising, in cases of duplicate or erroneous payment, and similar cases. Detailed conditions, how to request, and the process follow the refund policy. The refund policy will be posted on the website when paid purchases begin.
  3. When a refund is made, the right to use that key ends, and the user must delete the key and stop using it.
  4. Nothing in this Article limits the rights guaranteed to consumers by applicable law.

Article 8 (Notes sync service)

  1. Notes sync is an optional feature that works only when the user turns it on in the App settings. The App's other features work without it.
  2. Notes are encrypted on the user's PC before they are sent, and the Operator cannot read their contents. The information stored and its retention period follow the Privacy Policy.
  3. Notes sync is provided to users during the trial and to users with a paid license. After the trial ends, sync stops if there is no paid license, and notes on this PC can still be used.
  4. For stable operation, the following limits apply: 1,000 notes and about 5MB in total per connection code, a limit on how much can be sent at once, and a limit on requests per minute. Limits may change, and changes unfavorable to users are announced in advance under Article 3(2).
  5. Users are responsible for keeping their connection code. Anyone who knows the code can read and edit the notes in that space, and if the code is lost the Operator cannot recover it. Do not share the code with others.
  6. The Operator may change or suspend the service to improve it or for unavoidable reasons (outages, operational circumstances, legal requirements, etc.). When ending the service, the Operator will announce it on the website and in the App at least 30 days in advance; since notes also remain on your PC, you can keep using them after it ends.
  7. Notes stored on the server are deleted according to the retention periods in the Privacy Policy. Users can delete their notes on the server at any time in the App settings.
  8. Sync is a supplementary tool. We recommend keeping separate backups of important notes.

Article 9 (User obligations)

Users must not:

  1. Attempt to bypass or extend the trial period
  2. Share, sell, or publish license keys, or bypass the license check
  3. Send excessive requests to the notes sync server, guess or probe other people's connection codes, or disrupt normal operation of the service
  4. Use notes sync to store or transmit illegal information or content that infringes the rights of others
  5. Otherwise violate applicable law, these Terms, or the EULA

If such conduct is confirmed, the Operator may restrict sync for the connection code concerned or refuse to accept the key in the next version. In that case the reason is given in advance, or, in urgent cases, after the action is taken.

Article 10 (Intellectual property and your notes)

  1. Copyright and other intellectual property rights in the App and the website belong to the Operator or the rightful holders.
  2. Rights in the notes and to-dos you write belong to you. The Operator cannot read your notes and does not use them beyond what is needed to provide the service.

Article 11 (Providing and changing the service and the App)

  1. The App is a supplementary tool for schedules, to-dos, and reminders. Do not rely solely on the App for important schedules or health management.
  2. The Operator may change features or release new versions to improve the App. Core features that existing buyers were using will not be removed or made paid without good reason.
  3. The App runs on the Microsoft Edge WebView2 runtime in Windows. Problems caused by an incompatible environment can be checked with the trial before purchase.

Article 12 (Limitation of liability)

  1. The Operator is not liable for damage caused by natural disasters, outages of third-party services (Cloudflare, GitHub, Lemon Squeezy, etc.), or causes attributable to the user, except where the Operator acted intentionally or with gross negligence.
  2. The App and notes sync provided by the Operator are provided as is to the extent permitted by law, and rights guaranteed to consumers by applicable law are not affected.
  3. Where the Operator is liable, compensation covers ordinary damages up to the amount actually paid by the user. This limit does not apply to intent, gross negligence, or liability that cannot be excluded by law.
  4. Nothing in this Article limits the rights guaranteed to consumers by law.

Article 13 (Personal information)

Processing of personal information follows the Privacy Policy.

Article 14 (Inquiries and dispute resolution)

  1. Please send complaints or questions about the service to [email protected]. We reply within 3 business days of receipt, and if handling takes longer we will tell you the reason and schedule.
  2. Disputes between the Operator and a user are first resolved through good-faith consultation. If that fails, you may seek help from a consumer dispute resolution body such as the Korea Consumer Agency (1372).
  3. These Terms are interpreted and applied under the laws of the Republic of Korea.
  4. If a lawsuit is filed in relation to these Terms, the court of first instance is the court with jurisdiction under the Korean Civil Procedure Act. Users residing abroad are not deprived of rights under the consumer laws of their country of residence.
