Privacy and Security

Square’s approach to security is designed to protect both merchants and their customers. Read about how we keep you and your information safe.

Privacy at Square

Square respects your privacy, and works hard to protect your personal information. We want you to understand how we may collect, store, use, share and protect your personal information, so please be sure to review our Privacy Notice. You acknowledged the Privacy Notice when you created a Seller account in order to use our services. We update this notice to reflect important changes to how we collect, store, use and share your personal information, so you should check back from time to time to review any changes. We may even send you notifications about updates to our Privacy Policy if we determine those are required. Check the date at the top of the Privacy Notice to determine when the most recent update took place. In most cases, any changes to the notice will be immediately effective unless a different effective date is indicated. Throughout this Privacy Notice, we will refer to our website, software, and services collectively as the “Service.” Please note, this Privacy Notice does not apply to information we collect by other means than your use of the Service (including offline) or from other sources.

Protecting the privacy of minors is especially important. For that reason, Square does not knowingly collect or solicit personal information from anyone under the age of 13 or knowingly allow such persons to register with our Service. If you are under 13, please do not send any information about yourself to us, including your name, address, telephone number, or email address. No one under age 13 is allowed to provide any personal information to or on Square. In the event that we learn that we have collected personal information from a child under age 13 without verification of parental consent, we will delete that information as quickly as possible. If you believe that we might have any information from or about a child under 13, please contact us.

Additionally, you must be over 18 in order to create an account with Square. 

Changes to Our Privacy Policy

If we change our privacy notices, policies and procedures, we will post those changes on our website to keep you aware of what information we collect, how we use it and under what circumstances we may disclose it. Changes to this Privacy Notice are effective once published, unless a different effective date is indicated.

Privacy for Your Customers

We understand that your customers expect you to take care of their personal information, and we have designed our Services with those expectations in mind. We have created a Privacy Notice that describes how Square processes personal information from your customers when we process payments or provide other services on your behalf.

Security at Square

To protect Square account holders and their customers, all information our customers submit is encrypted to our servers, regardless of whether you’re using a public or private WiFi connection or a data service on your phone (such as 4G, 5G or EDGE). Square complies with all required PCI standards.

Square protects its systems with industry-leading technology and security controls, including:

  • Square performs data encryption within the card reader at the moment of swipe.

  • Square’s software is developed using industry-standard security best practices.

  • Square’s servers are monitored around the clock by dedicated security staff.

  • Square’s employees act in accordance with security policies designed to keep your data safe.

Since Square itself is PCI compliant, we don’t require account holders to validate PCI compliance. Merchants who use Square for all storage, processing, and transmission of payment card data do not need to validate PCI compliance for those transactions. 

We strive to provide a safe environment for both buyers and sellers. Please review our Terms for items and services prohibited by Square.

Education: Please also visit our Support Center and The Bottom Line to search for articles that provide further privacy and security education, as well as other helpful information. For example, read about recognize and report phishing scams or the importance of 2FA (two factor authentication).
