Square Terms of Service

This is Square's Terms of Service — the legal contract you agree to when you create an account and use Square's payment processing, point-of-sale hardware, or business tools. The single most important thing to know is that this agreement includes a mandatory arbitration clause and class action waiver, meaning that if Square does something that harms you, you cannot sue them in court as part of a group and must instead resolve disputes individually through private arbitration. You have 30 days from account creation or from the date a material change is made to opt out of arbitration by sending written notice to Square.

This document constitutes Square's general Terms of Service governing the contractual relationship between Block, Inc. (operating as Square) and users of its suite of payment processing, point-of-sale, financial, and business management services, with acceptance effectuated by account creation or continued use. The most significant obligations include mandatory compliance with Square's Acceptable Use Policy, user responsibility for maintaining account security and all activity conducted under their credentials, and Square's right to suspend or terminate accounts at its sole discretion with limited notice. Notably, the agreement contains a binding mandatory arbitration clause with class action waiver, a broad unilateral modification right allowing Square to change terms with minimal notice, and an expansive intellectual property license grant covering user-submitted content. The document engages the Electronic Fund Transfer Act (EFTA), Payment Card Industry Data Security Standards (PCI-DSS), the California Consumer Privacy Act (CCPA), Regulation E, Bank Secrecy Act/AML requirements, and FinCEN money services business regulations; compliance teams should assess the adequacy of consent mechanisms for arbitration opt-out, the scope of data processing authorizations, and the financial services regulatory exposure arising from Square's payment facilitation activities.
