TERMS OF SERVICE
Terms for using BlockAck
These terms govern access to BlockAck.com, merchant accounts, APIs, dashboards, payment monitoring, callbacks, and related services. By creating an account or using the service, you agree to them.
Effective and last updated: September 24, 2026Important: This document is a product-specific baseline, not legal advice. It cannot eliminate all legal risk. BlockAck should have qualified counsel review it for the operator’s legal entity, location, customers, and launch jurisdictions before accepting production users.
1. Eligibility and authority
You must be legally able to contract and, if acting for an organization, authorized to bind it. You must provide accurate account information, keep it current, and safeguard credentials. One person or entity may not create accounts to evade limits or enforcement.
2. The service and non-custodial boundary
BlockAck provides software and APIs for payment operations such as invoices, public-address derivation through connected infrastructure, payment monitoring, dashboards, callbacks, and related risk indicators. BlockAck is not a bank, wallet, exchange, escrow, money transmitter, fiduciary, investment adviser, tax adviser, or legal adviser. Customer payments are intended to settle directly to merchant-controlled wallets. BlockAck does not possess merchant private keys and cannot spend, freeze, reverse, recover, refund, or redirect blockchain transactions.
3. Merchant responsibilities
You are solely responsible for your products and customers; wallet ownership and backups; private keys and seed phrases; receiving-address verification; pricing, refunds, taxes, records, consumer disclosures, sanctions/export controls, licenses, registrations, and all laws applicable to your business; API-key security; validating callbacks; confirming final settlement before fulfillment; and obtaining lawful rights to all submitted data. Risk indicators are advisory and are not legal determinations.
4. Prohibited use
You may not use the service for unlawful, fraudulent, deceptive, abusive, sanctioned, infringing, or harmful activity; unauthorized financial services; evading legal restrictions; malware, credential theft, trafficking, exploitation, or prohibited goods; probing or disrupting systems; accessing another tenant; misrepresenting availability or custody; or submitting private keys, seed phrases, special-category data, or unnecessary personal data. We may suspend, limit, preserve, or terminate access to protect users, infrastructure, or legal compliance.
5. Networks and third parties
Bitcoin, Lightning providers, stablecoin networks, Solana or other future networks, BTCPay, wallets, nodes, cloud providers, email providers, and third-party APIs are independent systems. Their availability, fees, finality, forks, congestion, bugs, policy changes, compromise, or loss are outside BlockAck’s control. Roadmap statements are plans only, not commitments. Provisioning, synchronization, or a displayed status does not by itself establish payment readiness.
6. Fees and subscriptions
Current public plans include a free monthly API allowance and a Bitcoin-priced Starter subscription. Prices, limits, and features shown at purchase apply for the stated period. Network fees are separate. There are no automatic wallet debits; renewal requires payment of a new invoice. Fees are non-refundable except where required by law or expressly stated. We may change future prices or plans with reasonable notice, without silently repricing an already-paid period.
7. Availability, changes, and beta features
The service may be unavailable, delayed, incomplete, or changed. We may impose limits, perform maintenance, discontinue features, or label functionality as preview, sandbox, demo, or beta. Demo data and development-only mock APIs are not production transactions. No service-level commitment applies unless stated in a separately signed agreement.
8. Intellectual property and feedback
BlockAck and its licensors retain rights in the service, software, branding, and documentation. Subject to these terms, you receive a limited, revocable, non-transferable right to use the service for your internal business operations. You retain rights in your data and grant BlockAck the rights needed to host, process, transmit, and secure it. Feedback may be used without restriction or compensation.
9. Confidentiality and data
Each party must use reasonable care with non-public information and may use it only to perform under these terms, except information lawfully public, independently developed, rightfully received, or required to be disclosed. The Privacy Policy describes personal-data handling. You must not use the service to store secrets or data unnecessary for payment operations.
10. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” BLOCKACK DISCLAIMS ALL EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, SECURITY, AVAILABILITY, AND THAT TRANSACTIONS, CALLBACKS, RISK SIGNALS, OR NETWORK DATA WILL BE ERROR-FREE, FINAL, OR SUITABLE FOR YOUR LEGAL OBLIGATIONS.
11. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, BLOCKACK AND ITS AFFILIATES, PERSONNEL, AND SUPPLIERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES; LOSS OF PROFITS, REVENUE, DATA, GOODWILL, KEYS, DIGITAL ASSETS, OR BUSINESS; OR THIRD-PARTY, NETWORK, WALLET, SECURITY, OR REGULATORY EVENTS. BLOCKACK’S AGGREGATE LIABILITY ARISING FROM THE SERVICE WILL NOT EXCEED THE GREATER OF US$100 OR THE FEES YOU PAID TO BLOCKACK FOR THE SERVICE DURING THE 12 MONTHS BEFORE THE EVENT. THESE LIMITS DO NOT APPLY WHERE LIABILITY CANNOT LAWFULLY BE LIMITED.
12. Indemnity
To the extent permitted by law, you will defend, indemnify, and hold harmless BlockAck and its affiliates, personnel, and suppliers from third-party claims, losses, penalties, costs, and reasonable legal fees arising from your business, products, customers, data, wallets, taxes, refunds, legal compliance, breach of these terms, or misuse of the service. BlockAck will provide reasonable notice and allow you to control the defense, subject to reasonable participation and settlement protections.
13. Suspension and termination
You may stop using the service. We may suspend or terminate access for breach, risk, nonpayment, legal requirements, security, or discontinuation. Upon termination, rights to use the service end. Provisions that by nature should survive do survive, including payment obligations, ownership, disclaimers, liability limits, indemnity, and dispute terms.
14. Disputes and general terms
These terms, together with incorporated policies and any signed order, are the agreement about the service. Mandatory law may grant rights that cannot be waived. Governing law, venue, the operating legal entity, and its notice address have not yet been finalized and must be completed with qualified counsel before production launch; until then, no jurisdiction-specific arbitration or venue clause is represented here. You may not assign these terms without consent; BlockAck may assign them with its business. Invalid provisions are limited to the minimum necessary, and failure to enforce is not waiver. Force-majeure events excuse delay where permitted by law.
15. Changes and contact
We may update these terms prospectively. Material changes may require notice or renewed acceptance. Continued use after an effective date constitutes acceptance where permitted by law. Contact: support@blockack.com.
