YBK Audio: Music software made simple

1. Who we are

These terms govern your purchase and use of software sold on ybkaudio.com. The seller is YBK Audio, a sole proprietorship registered in the Republic of Korea and owned by Kim Yeonbum, business registration number 288-17-02789, 221 Seolleung-ro, Gangnam-gu, Seoul, Republic of Korea. You can reach us at ybkaudio@gmail.com.

By buying, installing or using Instrument Player, MultiConsole, Beatmaker or MixAlign (“the Software”), you agree to these terms.

2. Payment and our reseller, Paddle

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders: it processes your payment, charges and remits any sales tax or VAT, and issues your invoice. Your purchase is also subject to the Paddle Buyer Terms. YBK Audio never receives your card details.

Prices are shown in US dollars on each product page. Paddle may show the total in your local currency and add tax where required.

3. Your license

The Software is licensed, not sold. When your payment completes, you receive one license code by email. That code grants you a personal, non-exclusive, non-transferable right to install and use the Software on one computer at a time.

• One computer at a time. The code activates the Software on one computer. To use it on another computer, you move it: release it from the first computer (in the Software’s Settings, “Release license”) and activate it on the second. The Software stops running on the first computer when the license leaves it.
• Moves. A license can be moved once every 30 days. Only the computer the license is on can release it. If that computer can no longer do so (for example because it broke down), write to us and we will release it after checking that the license is yours. We may also help with further moves when there is a good reason.
• Your computers only. Moving a license is for moving between your own computers. A license may not be shared with, lent to, or used in turn by other people.
• What doesn’t need a move. Reinstalling or resetting Windows, Windows and driver updates, app updates, and replacing the drive, RAM, graphics card, monitor or network hardware on the same computer. A new motherboard or CPU, a different computer or a new virtual machine counts as a new computer and needs a move.
• Activation. Activating needs an internet connection, and so does moving a license. See the Privacy Policy for exactly what is sent.

Free launch-month licenses (claimed free of charge between 19 September and 19 October 2026) follow the same rules, including moves, with these additions. There is one free license per person, not per email address, and it is for your own use. It may not be sold, traded or given away, and it is not a purchased license. To enforce this we compare the email addresses and IP addresses used to claim licenses (see the Privacy Policy). If one person collects several free licenses (for example under different email addresses) or offers a free license for sale, we may refuse further claims and deactivate the extra licenses. A person, not an automatic rule, makes that decision, and you can write to us if you think we got it wrong. This paragraph applies to licenses claimed from 26 September 2026.

You may use the Software for personal and commercial work. Music, recordings and MIDI files you make with it belong to you.

4. Updates

A purchased license is for the software as you bought it. New versions, updates and other editions may be free or sold separately. We may change or remove features in updates, but an update will not remove the core function of the product you bought.

A free launch-month license includes every update released up to and including 19 October 2026. Updates released after that are for purchased licenses. The free license keeps working, for good, with the last version released on or before 19 October 2026, on any computer you move it to. Later versions do not run with it; to use them, buy the Software.

5. What you may not do

• Share, sell, rent or publish your license code or the Software.
• Circumvent, disable or tamper with license activation.
• Reverse engineer, decompile or disassemble the Software, except where the law expressly allows it despite this restriction.
• Use the Software to break the law or infringe anyone else’s rights.

6. Third-party plugins and audio

Instrument Player loads VST3 instruments made by other companies. Those plugins are governed by their own licenses, which you must hold separately; we are not responsible for how they behave. MultiConsole processes audio already playing on your computer; it records only when you press Record, saving the file to your own computer, and never transmits audio. Beatmaker reads the audio and MIDI files you point it at; it never moves, changes or uploads them. MixAlign reads the audio files you open; it never changes or uploads them, and what it exports (PDF reports, WAV loops, sessions) is saved only where you choose.

7. Problems with an order

If something is wrong with your order, email ybkaudio@gmail.com with your order number and we will look into it. If a payment is reversed, the license code it paid for is deactivated.

8. Warranty

We build the Software carefully and will try to fix problems you report, but it is provided “as is”, without warranties of any kind beyond those that cannot be excluded by law. Check the system requirements on each product page before buying.

9. Limitation of liability

To the fullest extent permitted by law, YBK Audio is not liable for indirect or consequential losses (including lost data, lost work or lost profits) arising from use of the Software, and its total liability for any claim is limited to the amount you paid for the product concerned. Nothing in these terms limits liability that cannot legally be limited, such as for intentional misconduct or gross negligence.

10. Termination

Your license ends automatically if you break these terms. On termination you must stop using and uninstall the Software.

11. Governing law

These terms are governed by the laws of the Republic of Korea. If you buy as a consumer, you keep any mandatory protections given by the law of the country you live in, and nothing here removes your statutory rights.

12. Changes

We may update these terms. The version in force when you bought applies to that purchase; the date at the top of this page shows the latest revision.

Short version: we collect what it takes to sell and license the Software, to keep the free launch to one license per person, and to see whether our emails arrive and how many people use the app. Instrument Player also sends three usage numbers (app version, operating system, minutes open), which the activation window tells you about. We never sell personal data, use no advertising trackers and no cookies of our own, and never receive your audio, MIDI or files.

1. Who is responsible

YBK Audio (sole proprietor Kim Yeonbum), 221 Seolleung-ro, Gangnam-gu, Seoul, Republic of Korea, business registration number 288-17-02789. Contact: ybkaudio@gmail.com. This policy applies wherever you live; section 7 lists the rights you have, and section 8 the extra points for particular regions.

2. What we collect, when, and why

• When you buy. Paddle, our Merchant of Record, collects your name, email address, country, postal code where required, and payment details. Paddle keeps your card details; we never receive them. We receive your email address, the product, the order number, the amount paid out to us, and any later refund or chargeback, so we can deliver your license, keep sales records and handle problems.
• When you ask us to tell you when an app is out. Your email address, which app(s) you picked, the page you signed up on, the link that sent you (if any) and your country (worked out by Cloudflare). We use it only to send a confirmation and one email when that app is ready to buy; nothing else, and it is never shared. If you tick Join our newsletter, we also email you about new apps and updates now and then; every newsletter has an unsubscribe link. To be taken off the list, reply to any of our emails or write to us.
• When you download 432hz. Nothing about you: 432hz is a free download with no sign-up and no email. The download button is counted anonymously, like other clicks (see “When you visit this website”). If you choose to name a price, Paddle’s checkout asks for your email address for the receipt. If you then pay, we keep a record of the payment with that email address, as with any purchase, and send you one thank-you email; it is not added to any mailing list.
• When you claim a free launch license. Your email address; the website or link that sent you to us and its campaign tag, if any; the first page you saw; the random visit number described below; your browser language; whether you use a phone or a computer; your country and time zone (worked out by Cloudflare from the connection); and your IP address. We also record the IP address that opens the confirmation link (often your email provider’s link scanner rather than you). The email address receives the confirmation link, the code, one email about two weeks later asking how the Software works for you, and a few short reminders before the free month ends, each with an unsubscribe link. The IP addresses let us keep the free launch to one license per person: without them, one person could collect many licenses under different email addresses and sell them. If you choose to pay through “name your price”, Paddle handles that payment as described above.
• When we email you. Our email provider, Resend, tells us whether each email was delivered, delayed, bounced or marked as spam, so we notice when a license code doesn’t arrive. We do not track whether you open emails or click links in them.
• When you activate the Software. The app sends your license code, a machine fingerprint, the computer’s name and platform as Windows reports them, and the time. We also record the IP address and country of the activation. The fingerprint is a one-way code derived from your motherboard and CPU identifiers; it cannot be turned back into them and exists only so a license runs on one computer at a time. The computer name is whatever you or the manufacturer called your PC, which sometimes includes a person’s name; we use it only to answer support questions about that activation. When you release or move a license, we record when that happened, and the name of the computer it left, so that the once-every-30-days limit can be applied.
• Every time the app starts. The app checks its license with our license service; the license cannot work without this. With that check we record the time, the IP address and country, and count how many times and on how many days each license has been used. These counts tell us how many people really use the app.
• Usage statistics (Instrument Player 1.8.0 and later). The activation window tells you about this when you activate. Once per session (about 15 seconds after the next start) the app sends a short report about the previous session: a random install ID made by the app (not your license code, email address or computer, and not linked to them), the app version, your operating system, and how many minutes the app was open. Nothing else: no plugin names, no hardware details, no audio, notes, MIDI or files. There is no switch for this inside the app; you can object by emailing us (see section 7). If you said no to the usage question in an earlier version, nothing is sent. Versions 1.4.0 to 1.7.x asked separately and sent more detail only if you said yes; those reports follow the retention below. We do not store your IP address or country with these reports; the IP is used only to limit how many reports one address can send per hour and is deleted after an hour.
• When you email us or send feedback. Your email address (optional in the feedback form), whatever you choose to write, and the page you sent it from, used to read and answer your message.
• When you visit this website. Anonymous visit statistics: which pages were viewed, clicks on Buy and download buttons, how far a checkout or the free-license form got, the country (from Cloudflare), whether the device is a phone or a computer, and the website or link that sent you (the full address of the page that linked here, with any email address or sign-in code removed). A visit is tied together only by a random number that exists while the page is open; it is never stored on your device, and these statistics contain no IP address, name or email. If you then sign up on one of our forms (a free license or a download), that visit number is sent and kept with your sign-up, so we can see which pages of this site that visit viewed before signing up. We also use Cloudflare Web Analytics, which counts page views, browser and operating system, screen size and page loading speed without cookies and without storing your IP address. The IP address that sends a form is kept for one hour to stop automated sign-ups and messages.

3. Why we are allowed to (legal bases)

• To perform our contract with you: selling and delivering the license, activating it, checking it when the app starts, sending the emails the license needs, and answering you.
• To meet legal obligations: tax, accounting and consumer-protection records.
• Our legitimate interests, weighed against yours: keeping the free launch to one license per person and preventing resale (IP addresses), noticing undelivered emails, counting how the store and the app are used, and the three usage numbers from Instrument Player 1.8.0 and later (app version, operating system, minutes open), so we can count how many people use the app and which versions and systems to support. You can object at any time by emailing ybkaudio@gmail.com (section 7).
• Your consent: the detailed usage statistics from Instrument Player 1.4.0 to 1.7.x that you said yes to, and anything else where the law of your country requires consent. You can withdraw consent at any time; that doesn’t affect what was processed before.

In the EU, EEA and UK these are Articles 6(1)(b), (c), (f) and (a) of the GDPR. In Korea, processing is based on Article 15(1) of the Personal Information Protection Act (contract, legal obligation and the controller’s legitimate interest) (including the usage numbers from Instrument Player 1.8.0 and later, which are necessary for providing and improving the service) and, for the detailed statistics from versions 1.4.0 to 1.7.x, your consent.

4. How we use it

To deliver and support your license; to keep the free launch fair; to fix problems and decide what to improve; and to keep simple business statistics (sign-ups, installs, sales). We do not make decisions about you by automated means alone: if a free license looks like one of several collected by the same person, a person reviews it before anything happens, and you can write to us about it. We do not use your data for advertising or profiling, and we do not sell or rent it.

5. How long we keep it

• Records of contracts, payments and refunds: 5 years, as required by the Korean Act on Consumer Protection in Electronic Commerce. Records of complaints and disputes: 3 years.
• License and activation records: for as long as the license exists, then up to 5 years alongside the sales record.
• IP addresses recorded at sign-up, confirmation, activation and app start: 12 months from when they were recorded, then deleted automatically.
• App start counts per license: until 13 months after the last start.
• Our internal activity log (sign-ups, emails, activations, payments): 60 days.
• Usage statistics: the record for an install ID is deleted about 13 months (400 days) after its last report; combined counts are kept about 3 months.
• Anonymous website statistics: about 3 months. IP addresses used against automated form submissions: one hour.
• Email list: until you unsubscribe. After that we keep only the fact that you unsubscribed, so we never email you again by mistake.

How we delete. When a period ends, the record is deleted automatically from the systems in section 6, or the personal fields in it are erased, so it cannot be restored. We keep no paper records. Records we must keep by law are stored apart from the ones we use day to day.

6. Who processes it, and where

We use the following services. Because they are based outside Korea, your data is transferred abroad over the internet at the moment of each event listed in section 2 (buying, claiming, activating, starting the app, emailing, visiting). Where the law requires it, these providers protect transfers with standard contractual clauses or equivalent safeguards. You can refuse the transfer by not purchasing or claiming; the Software cannot be licensed without it.

Each service keeps data only as long as needed to provide its function to us, or as its own legal obligations require.

7. Your rights

Wherever you live, you can ask us to: show you the personal data we hold about you and give you a copy (as a CSV file); correct it; delete it; restrict or stop processing it; and object to processing based on our legitimate interests, including the IP address check. You can withdraw consent to the detailed usage statistics of versions 1.4.0 to 1.7.x, or object to the 1.8.0 usage numbers, by emailing us. Email ybkaudio@gmail.com; we reply within 10 days and at the latest within one month. We may ask you to write from the address you used, so we know the request is yours. Some records must be kept for the periods in section 5 even after a deletion request; your license keeps working after we delete your personal data.

If you are unhappy with our answer, you can contact the data-protection authority where you live. In Korea: the Personal Information Dispute Mediation Committee (kopico.go.kr, 1833-6972), the Personal Information Infringement Report Center of KISA (privacy.kisa.or.kr, 118), the Supreme Prosecutors’ Office cybercrime unit (spo.go.kr, 1301) and the Korean National Police Agency cyber bureau (ecrm.police.go.kr, 182).

8. For particular regions

• EU, EEA, UK and Switzerland. You also have the right to data portability and to lodge a complaint with your supervisory authority. We have not appointed an EU or UK representative; contact us directly.
• United States (including California). In the last 12 months we collected identifiers (email, IP address, license code), commercial information (purchases), internet or app activity (as in section 2) and approximate location (country). We do not sell personal information or share it for cross-context behavioral advertising, and we do not use sensitive personal information. You may exercise the rights to know, delete and correct through an authorized agent, and we will not treat you differently for doing so.
• Other countries (for example Brazil, Canada, Japan and Australia). You have the rights your local law gives you in addition to those in section 7; contact us to use them.

9. Cookies

We set no cookies of our own and use no advertising trackers. Paddle’s checkout may set cookies it needs for payment and fraud prevention, and Cloudflare’s bot check may use browser signals to tell people from bots.

10. Security

All data travels over encrypted connections. Access to the services above and to our records is restricted to YBK Audio and protected by secret keys that are never published.

11. Children

Our store and apps are not directed at children under 14 (under 16 in the EU where that age applies, under 13 in the United States), and we do not knowingly collect their personal data. If you believe a child has given us personal data, contact us and we will delete it.

13. Changes

If this policy changes, we update the date at the top of this page. Significant changes are announced on this website before they take effect, and the app asks again before sending anything new.

1. Refunds and problems with your order

You can ask for a refund within 30 days of your purchase. After 30 days, purchases are not refundable. To ask for a refund, or if something else is wrong with your purchase, email ybkaudio@gmail.com from the address you bought with. Include your order number from the Paddle receipt and tell us what happened. We read every message and reply within 3 business days.

2. How payments are reversed

Payments are handled by Paddle, our Merchant of Record, so any refund is issued by Paddle to your original payment method. When a payment is refunded, the license code it paid for is deactivated and the Software stops working on any computer where it was activated.

3. Your statutory rights

Nothing on this page limits any rights you have under the consumer protection laws of the country where you live — including, for buyers in the EU or UK, the statutory withdrawal right described in the Paddle Refund Policy.
