QuantPilot License and After-Sales Terms Version: 20260928-v4 Published: 2026-09-28 1. Price and license A one-time payment of 1,600 USDT grants perpetual use of the purchased version on one computer, with no monthly or annual license fee for that version. Trading capital, trading fees, internet, hardware and hosting are not included. The license belongs to the original purchaser. Do not share it between users, resell, sublicense or distribute the package or certificate. Delivery of Python files does not transfer copyright; rights permitted by law remain unaffected. 2. Delivery and system requirements The purchase page specifies the release, supported environment and delivery method. Successful payment verification unlocks downloads. If verification or delivery fails, contact support with the TXID; do not pay again. The current delivery is a Python 3.11–3.13 program package, not a standalone EXE or App. Setup, activation and live data require internet. Check the operating-system and hardware requirements before purchase. Do not transfer funds before checkout opens. 3. Maintenance coverage Send maintenance requests and written notices to QuantPilot090@gmail.com. Internal procedures do not extend deadlines under these terms or applicable law. For 12 months from delivery, support covers installation, activation, provided API connection features and reproducible software faults. General cases receive an initial reply within 2 service days; this is not a resolution guarantee. License, payment, refund and consumer complaints remain receivable after the support period under these terms and applicable law. Support does not include managed trading, custody of funds, investment advice, custom strategies, 24-hour monitoring or unlocking exchange accounts. Support never needs private keys, seed phrases, verification codes or withdrawal permission. Do not send Secret Keys in chat. 4. Updates and perpetual use Bug fixes and security updates for the purchased version are included for 12 months from delivery. Support will explain known impacts and workarounds when a fix takes longer. Unresolved material defects are handled under section 8. New features, major releases and adaptations to future operating systems or exchange interfaces are not all promised free of charge. Optional paid products require advance pricing and separate agreement. The purchased version remains licensed perpetually; this does not promise lifetime human maintenance, permanent exchange availability or uninterrupted cloud services. 5. Computer binding, reinstalling and replacement First activation binds one computer. Choose that computer before activation; a second computer cannot reuse the same license. Keep your private license code and license backup when reinstalling on the same computer. Support can help check its identity and recovery options. Self-service device transfer is unavailable, and cross-computer transfer is not promised. Contact support before replacing failed hardware or after an identity change to establish a feasible solution. New-computer activation is not guaranteed without written confirmation; do not buy again merely to troubleshoot. Statutory defect remedies remain available. 6. Payment and fees Use USDT on TRON Mainnet (TRC20). Read the official payment address and QR, pay exactly 1,600 USDT, then enter the on-chain transaction ID (TXID) on the same page. No sign-in, order creation or wallet signature is required. Payments may originate from an exchange or your own wallet. Downloads unlock after final confirmation, USDT token, recipient, exact received amount and prior-redemption checks. Use the recipient and amount on the official payment page. Pay network fees separately without reducing 1,600 USDT. Contact support for underpayments, overpayments, duplicate payments, payments from the previous flow or verification problems; do not pay again. Funds are not donations or automatically forfeited. Wrong-network, wrong-token or third-party-address transfers may be unrecoverable, without excluding liability imposed by law. This simplified flow verifies the payment, not the payer's identity. TXIDs are public; the first submission that passes verification receives download access, so a third party may redeem first. Contact support for independent review if that occurs. Automated attribution does not exclude the actual payer's statutory rights. Save the private license code after success for download recovery and device activation. A public TXID alone cannot retrieve that private code. 1,600 USDT is the total software price, including applicable seller sales taxes; no hidden fees are added afterwards. Platform charges and the buyer's personal taxes are separate. The actual merchant supplies legally required documentation. 7. Seven-day refunds and cancellation You may request a full software-fee refund without giving a reason within 7 calendar days starting the day after actual delivery of a downloadable version and valid license. Send a retainable written cancellation notice to QuantPilot090@gmail.com. Downloading or activating does not automatically remove this right; this offer does not use a digital-content exception to exclude its seven-day refund. You may also cancel and request a refund before delivery. Include the TXID and purchasing identity. A TXID, explanation or screenshots help verification but complete attachments and prior support approval are not conditions for timely notice. After this window, non-delivery, defects, duplicate payments and other statutory grounds remain reviewable. Statutory periods are not shortened. 8. Installation failures, material defects and later requests For reproducible defects materially affecting core functions in an environment expressly supported when purchased, support will investigate and offer a fix or reasonable alternative. If remediation is not possible within a reasonable period, cancellation, a price reduction or other appropriate remedies will be provided as required by law and the circumstances. Expiry of support does not remove statutory liability. Trading losses, disappointing returns or no longer needing the software do not alone prove a defect or create an additional unconditional refund right after seven days. This does not limit seven-day refunds, defect remedies or other statutory rights. 9. Refund method and license consequences Refunds are due within 15 calendar days starting the day after valid cancellation notice, or sooner if required by law. Internal review does not restart that deadline. Refunds normally use USDT (TRC20) to the verified original payer wallet. If that address cannot receive funds, an alternative is verified securely. No refund processing fee applies. The seller bears outbound network fees without reducing the refundable software fee. Other legally refundable necessary expenses are handled as required by law. Refunds are processed manually by support; automatic payouts are not currently available. After cancellation, stop using and remove the software and license copies. Backend licensing and downloads will be disabled. Previously issued offline certificates cannot be remotely erased; this does not permit use after cancellation. A refund does not close trading positions or withdraw assets for you; manage existing positions directly through the exchange. 10. Account and troubleshooting security Keep your private license code, payment record and license backup safe. Provide only necessary, redacted troubleshooting information. Uploading exchange credentials to the backend requires separate explicit consent; purchase or acceptance of these terms is not consent to upload keys. Use minimum API permissions and avoid withdrawal permission. Check exchange positions and revoke suspicious keys if problems arise. Stopping the application does not close positions. Personal data is handled under the privacy notice and applicable law. 11. Trading risks and responsibility This software is a tool, not a principal guarantee, profit promise, fixed win rate or managed investment service. Simulations do not prove live performance. Slippage, fees, leverage, outages, exchange restrictions and liquidation can cause losses; stop-loss execution at a set price is not guaranteed. Users choose strategies, funds, permissions and whether to enable live trading. These warnings do not exclude mandatory merchant liability, including intentional misconduct, gross negligence or legally imposed product/service liability. There is no blanket liability waiver or blanket cap at the software price. 12. Version and complaints Version 20260928-v4, published 2026-09-28. Merchant: QuantPilot Technology Co., Ltd. (English translation). Contact address: 101 S San Fernando St, San Jose, CA 95113, United States. Phone: +1 (201) 913-4284. Email: QuantPilot090@gmail.com. Each purchase record retains the accepted terms version and full text. Later changes do not retroactively reduce existing rights. Differences between translations are interpreted reasonably without reducing consumer rights. Taiwan law and other applicable mandatory rules govern; lawful court, consumer complaint and mediation options remain available. Send complaints, refund requests and written notices to QuantPilot090@gmail.com. Unresolved disputes may be referred to applicable consumer-protection or judicial channels. Internal procedures do not limit timely notice or complaint rights.
