1. Nature of the service

• Mecus is a Windows overlay utility that provides convenience features such as a timer, web/music panels, an input-mode helper, external-window display, an in-app billboard, and screen sharing.
• Mecus does not read or modify the memory or files of other programs, and does not provide code injection, packet tampering, automated input, or security-bypass features.
• Some features may be limited or suspended due to policy changes by external platforms such as operating systems, security software, Discord, Firebase, Cloudflare, and the payment service provider (PSP).
• Mecus is not an official service of any specific game company or platform; each platform sets its own terms and operating policies.
• Mecus is not an official service of, and is not affiliated with, NEXON Korea, MapleStory, or Maplescouter. Public character information is based on the NEXON Open API, and conversion stats and boss multipliers are shown for reference based on lookups from the public Maplescouter service.

2. Accounts and eligibility

• Account-based features require Discord login. Members must keep their account secure; damages caused by account sharing are the member's responsibility.
• The service assumes users aged 14 or older. If a minor makes a paid purchase, the consent of a legal guardian is required.
• For security and to prevent duplicate use, one account is intended for one device; logging in from a new device may end the existing session.

3. Pro pass and billboard pass

• The Pro pass is a digital pass that unlocks the app's Pro features for 30 days. The standard price is KRW 4,000.
• The Pro pass can be stacked up to a maximum of 90 days. If more than 61 days of Pro time remain, additional purchases are restricted to prevent exceeding the 90-day cap; purchases become available again once 60 days or fewer remain.
• The billboard pass is a Mecus-app-only digital pass used solely to display a one-time message on the in-app billboard. The billboard is a one-way, one-time display that automatically disappears about 12 hours after being shown; it is not a real-time chat, messaging, or matchmaking service. The price is KRW 500 per pass, and the quantity can be chosen at checkout.
• Multiple billboard passes can be used at once for a single display. The number of passes used can affect the number of lines, the color tier, and whether top-pinning is available.
• Paid billboard passes are usable for 90 days from the purchase date. Free coupons, event coupons, and reward coupons expire at the separately notified time.
• The Pro pass and billboard pass may be used only within Mecus app features. They cannot be exchanged for cash, withdrawn, transferred, gifted, traded between users, resold, exchanged for external goods, or used to purchase game items.
• Once a digital benefit such as Pro activation or a billboard display begins, refunds or withdrawal of subscription may be restricted.
• Login-bonus billboard coupons may be granted to free or Pro users. Such coupons expire at the separately notified time and are not eligible for cash refunds.
• Members may not cash out passes or trade them with others. Use may be restricted where abnormal use is suspected, such as cashing out, account trading, payment-method theft, money laundering, or exchange for game items or external goods.

4. Use of third-party services

• Compliance with third-party terms. Users must review the terms and operating policies of the external programs and online services they use, and must not use Mecus in a manner that may violate those policies. Mecus is not responsible for any disadvantage arising from such use.
• Members must check the terms and operating policies of the games and online services they use, and must not use Mecus in a prohibited or potentially risky manner.

5. Screen sharing and external content

• Screen sharing lets a user offer a chosen screen to other participants. Before sharing, users must check for exposure of personal data, messengers, payment information, account information, and sensitive screens.
• Creating and joining screen-share rooms is available only to Discord-logged-in members. A room created by a free member allows up to 2 participants and a room created by a Pro member up to 6; limits may be adjusted based on operating conditions and abuse-prevention policy.
• Disadvantages may arise under the policies of external services during screen sharing, so members must check the relevant service's policy and use the feature at their own responsibility.
• Mecus does not guarantee the content of, or transactions on, external web pages, the Discord community, or user-written messages.

5-1. Boss Party Finder (BETA)

• The Boss Party Finder is a community board on which users post and manage recruitment listings and applications based on public character data they enter manually or refresh via the NEXON Open API and the public Maplescouter service (such as nickname, server, job, level, combat power, conversion stats, and boss multipliers).
• Data based on the NEXON Open API and Maplescouter is shown according to what those external services provide or publicly display, and may be missing or differ from the actual state due to lookup timing, maintenance, API delay, private profiles, or external-service changes.
• Where possible, source links are shown alongside values looked up from Maplescouter. Mecus does not own or guarantee those formulas, figures, or results, and users must verify the source and latest state themselves.
• Mecus does not guarantee the authenticity of specs, links, or conversations entered by users, or the outcome of any party.
• Clicking a nickname or member entry may open a Discord profile or the official Discord server; actual conversation and follow-through are the responsibility of the users involved.
• Listings or applications intended for impersonation, false specs, defamation, exposure of personal data, account trading, cash trading, paid leveling, inducement to violate a service's terms, or promotion of illegal programs may be removed or blocked.
• During BETA, the recruitment flow, input fields, Discord integration, retention period, and visibility policy may change.

6. External links and third-party content

• External links may appear in the app or on the website. Goods/services, payment, personal-data collection, and customer support on external pages are the responsibility of the relevant external operator, and Mecus does not guarantee their content or any external transaction.

7. Billboard, nicknames, and community use

• Billboard content, nicknames, and Discord-linked information may be visible to other users.
• Profanity, hate, exposure of personal data, impersonation, promotion of illegal programs, account trading, cash trading, gambling, speculation, adult content, malicious links, or dispute-inducing messages may be removed or blocked.
• The operator may review messages and account records to the extent necessary for reports, legal compliance, service protection, and dispute response.

8. Withdrawal of membership and data handling

• On withdrawal, account benefits such as held passes, Pro time, and billboard coupons are not recoverable.
• Even after withdrawal, transaction, consent, and security records required for payment, refunds, disputes, abuse response, or legal retention may be stored separately under the Privacy Policy.
• Free coupons, event coupons, and giveaways expire upon withdrawal and are not refundable in cash.

9. Service limitations and limitation of liability

• The operator may change, restrict, or suspend features for security, incident response, policy changes, prevention of illegal/improper use, and compliance with external-platform policies.
• Damages arising from a member's breach of these terms, concurrent use of illegal programs, payment-method theft, account sharing, or violation of third-party service policies are the member's responsibility.
• Absent intent or gross negligence, Mecus is not liable for damages arising from external-platform outages, third-party policy changes, the member's PC environment, use of external links, or prohibited use against any service.

10. Changes to these terms

• The operator may amend these terms when necessary; material changes may be announced via the app or website or may require re-consent.
• If a member does not agree to the amended terms, they may stop using the service and withdraw.

In case of any discrepancy, the Korean-language version of these Terms prevails for customers in South Korea.
