Last Updated: 10/23/2017

These Square Developer Terms of Service (“Agreement”) are a legal agreement between you (“you,” “your”) and Square, Inc. (“Square,” “we,” “our” or “us”) governing your use of Square’s software development kit files, tools, programs and utilities, as well as any plug-in or other application programming interfaces (“APIs”), sample code (including runtimes and libraries) and related documentation (collectively “Developer Tools”). Please read this Agreement carefully. To access the Developer Tools, you must accept all of the terms of this Agreement.

1. Your access to and use of Square Developer Tools and Content.

Your use of Square Developer Tools, and related materials made available to you is subject to and must comply with these Square Developer Terms of Service, Square’s Privacy Policy and the documentation and guidelines accompanying the Developer Tools.

  1. You may use Developer Tools to access information created or retained in a Square account (“Content”) and use Square payment processing services in connection with the applications, websites, products or services you operate and offer that interact with Developer Tools (your “Service”). Any payment processing enabled by you via a Square API requires a Square account and is subject to the Square Seller Agreement. You are solely responsible for, and Square disclaims all liability for, your Service.

  2. Your use of Developer Tools and Content are subject to certain limitations on access, calls and use as set forth in this Agreement, in the Square documentation accompanying such Developer Tools, or as otherwise provided to you by Square. If Square assigns you developer credentials or client IDs, you must use them with applicable Developer Tools. You will not misrepresent or mask either your identity or your Service’s identity when using the Developer Tools or developer accounts. If Square believes that you have attempted to exceed or circumvent these limitations, your ability to use Developer Tools and Content may be temporarily or permanently blocked.

  3. If your Service enables Square account holders (“Square Sellers”) to access their Content, Square Sellers must be presented with an ability to log into Square via the OAuth protocol. Sellers without a Square account should be given the opportunity to create a new Square account as provided by Square. You will not solicit or store Square passwords.

  4. You will use Developer Tools and operate Services which access Developer Tools only as permitted by law (including without limitation laws regarding the import or export of data or software, privacy or local laws). You will not use Developer Tools to encourage or promote illegal activity. You will only access the applicable Developer Tools following the implementation instructions and other requirements specified in the documentation for such Developer Tools, or as otherwise provided by Square from time to time.

  5. You are fully responsible for the security of data on your site and processed via your Services. You agree that at all times you and your Services will, at your effort and expense, be compliant with the Payment Card Industry Data Security Standard (PCI DSS) and the Payment Application Data Security Standard (PA-DSS), as applicable. At Square’s request, you will promptly provide us with documentation evidencing your compliance with PCI DSS and/or PA-DSS. You will use and access Developer Tools in accordance with the documentation and instructions provided by Square and in no circumstances will you store, process or transmit any cardholder’s account number, expiration date, or CVV2 except as described in that documentation. Further, you may not disclose card information to any third party, other than in connection with processing card transaction requested by your customer under the Service and in a manner consistent with PCI DSS and applicable law.

  6. You provide Square with a paid-up, royalty-free, revocable, worldwide, non-exclusive, non-transferable license to use your Services for testing, review or other related purposes to ensure that your Services comply with this Agreement. You may revoke this license at any time by providing written notice to us. If you revoke this license, this Agreement will immediately terminate.

  7. If your Service is provided at a fee to your customers, the fees you charge will be identified separately from the fees Square charges for its services.

  8. If you are using the Developer Tools in order to access and use the Apple Pay Web APIs and Apple Pay Platform, you must first accept the Apple Pay Platform Web Merchant Terms and Conditions.

  9. You may use certain Square APIs to facilitate payments to be collected by Square from Square Sellers.  Where available, Square APIs may be used to facilitate your collection of fees from Square Sellers. You are responsible for clearly and accurately describing the fees you collect from Square Sellers and you will notify them prior to making any changes to those fees. If you are utilizing Square APIs in order to charge fees to Square Sellers on a per-transaction basis, then you authorize Square to act as your agent for the limited purposes of holding,receiving, and disbursing payments, consisting of and/or sourced from such Square Sellers’payment processing proceeds.  You acknowledge and agree that Square does not act on the your behalf or on the Square Sellers’ behalf as money transmitter or a money services business (as those terms are commonly construed under applicable law) or in any other similar capacity except as expressly provided in this Agreement.  You acknowledge and agree that you will be solely responsible for collecting and remitting to any taxing authority any sales, value-added or similar taxes for your Service.

  2. Create a Service that functions substantially the same as Developer Tools or any Square service.

Square may limit or revoke your ability to use Square Marks at any point. All rights not provided in the Square Trademark Terms are expressly reserved by Square. We may change Square Marks from time to time.

NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED BY YOU FROM SQUARE OR THROUGH ANY DEVELOPER TOOL WILL CREATE ANY WARRANTY NOT EXPRESSLY STATED HEREIN.

  2. THIS LIMITATION OF LIABILITY SECTION APPLIES WHETHER THE ALLEGED LIABILITY IS BASED ON CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR ANY OTHER BASIS, EVEN IF SQUARE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. THE FOREGOING LIMITATION OF LIABILITY SHALL APPLY TO THE FULLEST EXTENT PERMITTED BY LAW IN THE APPLICABLE JURISDICTION.

10. Indemnification.

You will indemnify, defend, and hold us (and our respective employees, directors, agents, affiliates and representatives) harmless from and against any and all claims, costs, losses, damages, judgments, tax assessments, penalties, interest, and expenses (including without limitation reasonable attorneys’ fees) arising out of any claim, action, audit, investigation, inquiry, or other proceeding instituted by a person or entity that arises out of or relates to: (a) any actual or alleged breach of your representations, warranties, or obligations set forth in this Agreement, including without limitation any violation of our policies; (b) your wrongful or improper use of the Developer Tools or Content; (c) your violation of any third-party right, including without limitation any right of privacy, publicity rights or Intellectual Property Rights; (d) your violation of any law, rule or regulation of the United States or any other country; or (e) any other party’s access and/or use of Developer Tools with your unique name, password or other appropriate security code.

11. Modification of Terms.

We may amend this Agreement and the documentation and guidelines accompanying the applicable Developer Tools, at any time with notice that we deem to be reasonable in the circumstances, by posting the revised version on our website or communicating it to you through your Square account (each a “Revised Version”). The Revised Version will be effective as of the time it is posted, but will not apply retroactively. Your continued use of and access to the Developer Tools after the posting of a Revised Version constitutes your acceptance of such Revised Version. Any Dispute (as defined in Section 12) that arose before the changes will be governed by the terms of service in place when the Dispute arose.

12. Binding Individual Arbitration.

“Disputes” are defined as any claim, controversy, or dispute between you and Square, its processors, suppliers or licensors (or their respective affiliates, agents, directors or employees), including any claims relating in any way to this Agreement or the Developer Tools. You and Square agree to arbitrate all Disputes by a neutral arbitrator who has the power to award the same damages and relief that a court can.
ANY ARBITRATION UNDER THIS AGREEMENT WILL BE ONLY BE ON A INDIVIDUAL BASIS; CLASS ARBITRATIONS, CLASS ACTIONS, PRIVATE ATTORNEY GENERAL ACTIONS, AND CONSOLIDATION WITH OTHER ARBITRATIONS ARE NOT PERMITTED. YOU WAIVE ANY RIGHT TO HAVE YOUR CASE DECIDED BY A JURY AND YOU WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION AGAINST SQUARE. If any provision of this arbitration agreement is found unenforceable, the unenforceable provision shall be severed, and the remaining arbitration terms shall be enforced (but in no case shall there be a class arbitration). All Disputes shall be resolved finally and exclusively by binding individual arbitration with a single arbitrator administered by the American Arbitration Association (www.adr.org) according to this provision and the applicable arbitration rules for that forum. Consumer claimants (individuals whose transaction is intended for personal, family, or household use) may elect to pursue their claims in their local small-claims court rather than through arbitration so long as their matter remains in small claims court and proceeds only on an individual (non-class or non-representative) basis. The Federal Arbitration Act, 9 U.S.C. §§ 1-16, fully applies. If you are a consumer bringing a claim relating to personal, household, or family use, any arbitration hearing will occur within the county where you reside. Otherwise, any arbitration hearing will occur in San Francisco, California, or another mutually agreeable location. The arbitrator’s award shall be binding on the parties and may be entered as a judgment in any court of competent jurisdiction. We will pay the arbitration fees due to the American Arbitration Association for individual arbitrations brought in accordance with this section. If you prevail on any claim for which you are legally entitled to attorney’s fees, you may seek to recover those fees from the arbitrator. For any claim where you are seeking relief, Square will not seek to have you pay its attorney’s fees, even if fees might otherwise be awarded, unless the arbitrator determines that your claim was frivolous. For purposes of this arbitration provision, references to you and Square also include respective affiliates, agents, employees, predecessors, successors and assigns as well as authorized users or beneficiaries of Square services. Subject to and without waiver of the arbitration provisions above, you agree that any judicial proceedings (other than small claims actions in consumer cases) will be brought in and you hereby consent to the exclusive jurisdiction and venue in the state courts in the City and County of San Francisco, California, or federal court for the Northern District of California.

13. Governing Law.

This Agreement and any Dispute will be governed by California law and/or applicable federal law (including the Federal Arbitration Act) as applied to agreements entered into and to be performed entirely within California, without regard to its choice of law or conflicts of law principles that would require application of law of a different jurisdiction.

14. Limitation on Time to Initiate a Dispute.

Unless otherwise required by law, an action or proceeding by you relating to any Dispute must commence within one year after the cause of action accrues.

15. Assignment.

This Agreement, and any rights and licenses granted hereunder, may not be transferred or assigned by you and any attempted transfer or assignment will be null and void.

16. Other Provisions.

These Developer Terms of Service are a complete statement of the agreement between you and Square regarding the Developer Tools. In the event of a conflict between this Agreement and any other Square agreement or policy, this Agreement shall prevail and control the subject matter of this Agreement. If any provision of this Agreement is invalid or unenforceable under applicable law, then it will be changed and interpreted to accomplish the objectives of such provision to the greatest extent possible under applicable law, and the remaining provisions will continue in full force and effect. The Agreement does not limit any rights that Square may have under trade secret, copyright, patent, or other laws. No waiver of any term of this Agreement shall be deemed a further or continuing waiver of such term or any other term.

17. Survival.

The following sections of this Agreement survive and remain in effect in accordance with their terms upon termination of this Agreement: 6 (Ownership. Feedback), 7 (Termination), 8 (Disclaimer of Warranty), 9 (Limitation of Liability), 10 (Indemnification), 12 (Binding Individual Arbitration), 13 (governing Law), 14 (Limitation on Time to Initiate a Dispute), 15 (Assignment) and 16 (Other Provisions).
