What does Square do with personal data?
Manage customer payments, subscriptions where applicable, invoicing and billing. That is how Privacyboard describes a typical use of Square, as a starting point you can edit.
The data usually involved: customer names, email addresses, billing addresses, transaction identifiers and payment information handled by the provider.
Is Square a processor or a controller?
Square acts as processor for sellers' customer data but is typically an independent controller for payment, fraud and compliance processing.
Privacyboard does not prefill a role for this vendor on purpose. You are asked to choose, since the answer changes what your privacy policy says and which agreement matters.
Where does Square store personal data?
Square does not have one fixed location for every customer. The location depends on the plan, the account and the services you enable.
How to find yours: Check your account settings or Square’s data processing terms for where your data is stored.
Even when the main location is in the EU, ask whether subprocessors or support access involve a transfer outside the EEA, and record it if so.
Does Square have a data processing agreement?
Checked on 1 November 2026. Vendors change their pages, so check the date.
Yes. Square publishes the text of its data processing agreement on its own website. Article 28 of the GDPR requires a written contract with every processor, so this is the document to read and keep.
What we noted when we opened the page: Square 'Data Processing Terms', posted 27 Feb 2024. Covers Block, Inc. and Square Europe/International as processors of sellers' customer data. States no hosting location; mentions third-country transfers with EU SCCs.
A page that exists does not mean you are covered. Whether the agreement applies to you depends on your plan and on what you accepted, so record the decision yourself in your vendor list.
