Terms of sale and license

Last updated: 28 October 2026

The short version. You are buying a license to run our trading software on your own computers. Payment is in crypto and cannot be reversed. Trading is risky and every trade is your decision. The software runs on your machine with your own exchange keys, and we never hold your funds or your keys. Please read the full terms below before you buy.

1. Who we are and what these terms cover

These terms are an agreement between you and DELTAFLOW TECHNOLOGIES ("we", "us", "our"), the seller of the software on this website. They cover your purchase of GMAYFF Bot, FS-Monitor or a bundle of both (the "Software"), and your use of this website. By placing an order, downloading the Software or entering a license key, you confirm that you have read and accepted these terms. If you do not accept them, please do not buy or use the Software.

2. Who can buy

  • You must be at least 18 years old, and able to enter a binding contract where you live.
  • You must not be located in, or ordinarily resident in, a country or region subject to comprehensive sanctions, and you must not be on a sanctions list. We may refuse or cancel any order if we believe this is not the case.
  • You are responsible for making sure that trading derivatives and using trading software is legal where you live, and that your use complies with the terms of every exchange you connect to.

3. Your license

The Software is licensed, not sold. When your payment is confirmed, we grant you a personal, non-exclusive, non-transferable license to install and run the version you bought, on the one computer you activate, for your own trading and monitoring. The license is perpetual for the major version you bought. We keep all ownership and intellectual property rights in the Software.

What your package includes. Your package states how many copies of each app you may run at the same time, for example 1 bot and 1 monitor, or 3 bots and 1 monitor. That number is in your order and in your license key. Running more copies than your package includes needs a larger package. The Software stops an extra copy from starting.

One computer. Each license is for one computer only. Your license key is made for the computer you choose when you activate it on your order page, and it will not run on any other computer. All the copies in your package run on that one computer.

Moving to a new computer. You can move your license to a different computer by emailing us your order number. We then disable the old key and you can activate the new computer. We may refuse or limit moves that look like sharing a license, and may ask for reasonable details first. A replacement because of a failed or reinstalled computer is normally free.

Online check. Your license key is checked on your computer. The Software also checks over the internet, at start-up, whether a key has been disabled, and it must be able to do this at least once every 7 days. This check does not send your license key, your computer ID or any exchange details.

4. What you may not do

  • Share, sell, rent, lend, publish or otherwise give your license key or the Software files to anyone else, including by posting them online or in chat groups.
  • Run more copies at the same time than your package includes, or use one license to run the Software for other people, or offer it as a hosted, managed or signal service to others.
  • Copy, modify, decompile, reverse engineer, remove or bypass the license check, or try to produce keys, except to the extent the law gives you those rights and cannot be waived.
  • Use the Software to break any law, to manipulate markets, or to break an exchange's rules.

You are responsible for keeping your license key private. If you believe it has leaked, email us with your order number.

5. Updates and support

Your license covers the app versions and the number of copies in the package you bought, including fixes and minor updates that we choose to publish. A future major version may be offered as a paid upgrade. Support is provided by email on a reasonable-efforts basis, normally on business days. Support covers installing, licensing and running the Software. It does not include trading advice, strategy tuning or recovering losses. We may change the Software, add or remove features, and stop supporting an exchange that changes or closes its service.

6. Your exchange accounts and credentials

  • The Software runs on your computer and connects directly to the exchanges you choose, using API keys and wallet keys that you store on your computer. We do not ask for, receive or hold your exchange credentials, and we cannot trade, move or recover anything on your behalf.
  • You are solely responsible for creating, restricting and protecting your API keys. We strongly recommend trading-only permissions, withdrawals turned off, IP restrictions where available, and dedicated API or agent wallets rather than your main wallet.
  • Never send us API keys, private keys or seed phrases. We will never ask for them.
  • GMAYFF Bot, FS-Monitor and this website are independent products. We are not affiliated with, endorsed by or sponsored by Binance, Kraken, AsterDEX, Hyperliquid, SoDEX, Polymarket or any other exchange. Their names are used only to say which services the Software can connect to.

7. Trading risk and no financial advice

Trading perpetual futures and other leveraged products is risky. You can lose all of the money in your account, and sometimes more than you deposited. Funding rates, spreads and prices can change quickly, and a hedged or delta-neutral position can still lose money, for example through fees, slippage, funding costs, liquidation, exchange outages, delays, rejected orders or a hedge that does not fill.

The Software, this website, our documentation and any example or figure we show are tools and information only. They are not investment, financial, legal or tax advice, and nothing here is an offer or recommendation to trade. We are not a broker, dealer, investment adviser or fund manager. Past results, screenshots and back-tests do not predict future results. You decide what to trade, how large, and when to start or stop. You are responsible for every order the Software places on your accounts. Start with small sizes and test each exchange before you scale up.

8. Orders and payment

  • Price. Prices are shown in US dollars. You pay in one of the cryptocurrencies listed at checkout, at the exchange rate quoted when you start the order.
  • Exact amount, exact network. Your order page shows a wallet address, a network and an exact amount. Each order has its own amount, and that is how we match your payment to your order. Send exactly that amount, on exactly that network, from a wallet you control. Do not pay from an exchange account if it deducts withdrawal fees from the amount you send, because the order will receive less than required.
  • Time limit. The quoted amount is held for the time shown on the order page. After it expires, start a new order. If you pay after the order expires, contact us with your order number and the transaction ID, and we will try to match it manually.
  • Confirmation. The order is completed after your payment has enough network confirmations. This is usually a few minutes, longer on busy networks. Your license key and download links then appear on your order page.
  • Wrong amount or network. Blockchain payments cannot be reversed. If you underpay, we will ask you to pay the difference. If you overpay, we can refund the extra on request. If you send funds on the wrong network or to the wrong address, we cannot guarantee that they can be recovered, but we will try to help, and any network fees for recovering or returning funds are paid from the amount returned.
  • Taxes. The price shown is the price you pay. You are responsible for any tax, duty or reporting that applies to your purchase where you live.
  • Chargebacks. Crypto payments have no chargeback. If you have a problem with an order, email us first and give us a chance to fix it.

9. Delivery and downloads

The Software is delivered digitally from your order page. Keep your order link private, because it shows your license key and downloads. Each order has a limit on the number of downloads. If you reach it, or lose your files, email us with your order number and we will reset it. Please keep a copy of the files and your key, because the order page may not be available forever.

10. Refunds

Because the Software is digital and can be used as soon as you download it, purchases are final except in the cases below.

We will refund your order if, within 7 days of payment:

  • you did not receive your license key or download after your payment was confirmed, and we cannot fix it within 3 business days of your report; or
  • the Software will not start or run on a supported version of Windows, as described on this website, and we cannot fix it within 7 days of your report; or
  • the Software does not materially work as we described it on this website, and we cannot fix it within 7 days of your report.

We do not refund: trading losses or lower-than-expected profits; a change of mind after you have downloaded the Software or used your license key; problems caused by exchange outages, exchange rule changes, your own API settings, your computer, your internet connection or other software; or payments sent with the wrong amount or network (see section 8).

How refunds work. Email us with your order number, a description of the problem and, if possible, a screenshot (never include keys). We reply within 5 business days. Refunds are paid in USDT or USDC, on a network of your choice, for the US dollar price of your order, so the refund does not depend on price changes in the coin you paid with. Network fees are deducted from the refund. After a refund, your license is cancelled and you must stop using and delete the Software.

These rules are in addition to any rights you have under the consumer protection laws that apply to you, which we do not try to remove.

11. No warranty

The Software is provided "as is" and "as available". We work hard to make it reliable, but we do not promise that it will be error-free, uninterrupted, secure, or compatible with every exchange, account type or market condition at all times, or that it will make a profit. Exchanges can change or switch off their systems without notice, and that may stop part or all of the Software from working. To the fullest extent the law allows, we exclude all warranties and conditions that are not stated in these terms, including implied warranties of fitness for a particular purpose and non-infringement.

12. Limit of liability

To the fullest extent the law allows:

  • we are not liable for any trading losses, lost profits, lost opportunities, liquidations, funding or fee costs, missed or failed hedges, or losses caused by exchange outages, API changes, network delays, your settings or credentials, or your computer or internet connection;
  • we are not liable for indirect, incidental, special, consequential or punitive loss; and
  • our total liability to you for all claims connected with the Software or these terms is limited to the amount you paid us for the Software that gave rise to the claim.

Nothing in these terms limits liability that cannot be limited by law, such as liability for fraud or for death or personal injury caused by negligence, or removes rights you have under mandatory consumer protection laws.

13. Your responsibility for claims

You agree to cover us for any third-party claim, loss or cost (including reasonable legal fees) that results from your breach of these terms, your breach of an exchange's rules, or your use of the Software in a way that breaks the law. This does not apply to the extent that the claim is caused by our own fault.

14. Ending the license

You may stop using the Software at any time. We may cancel your license, disable your key, refuse updates or block your key in future releases if you break these terms (for example by sharing or reselling a key, or running it on more than one computer), if we have to by law, or after a refund. A key that we disable stops working the next time the Software checks online. The sections on risk, liability, intellectual property and governing law continue to apply after your license ends.

15. Your information

When you place an order we keep your order details, the payment transaction ID, and the email address you give us (which is optional, and is used only to send your receipt and answer support requests), and the computer ID you enter to activate your license. The computer ID is a code that the Software makes from your computer, and it does not reveal who you are or what is on your computer. Blockchain transactions are public by nature. We do not sell your information and we share it only with the service providers we need to run the store, such as our hosting and email providers, or when the law requires it. We never ask for or store your exchange credentials. To ask what we hold or to have it deleted where the law allows, email us.

16. Website and content

We try to keep this website accurate, but descriptions, screenshots, figures and supported-exchange lists may change as the Software and the exchanges change. If a description differs from these terms, these terms apply.

17. Changes to these terms

We may update these terms from time to time. The date at the top shows when they were last changed. The terms that applied when you placed your order continue to apply to that order, except where a change is needed to follow the law.

18. Governing law and disputes

These terms are governed by the laws of Malaysia. Please contact us first and give us a fair chance to resolve any dispute. If it cannot be resolved, it will be decided by the courts of Malaysia, subject to any mandatory consumer rights you have to bring a claim in the courts where you live.

19. General

These terms are the whole agreement between you and us about the Software. If any part is found to be unenforceable, the rest stays in force. If we do not enforce a right straight away, we do not lose it. You may not transfer your license or your rights under these terms to anyone else without our written consent. We are not responsible for delays or failures caused by events outside our reasonable control, such as network or exchange outages.

20. Contact

For support, refunds, license problems or questions about these terms, email our support address and include your order number (the first eight characters of your order link). Please do not send API keys or private keys.
