This means your name, payment card details, and purchase history can end up in Square's systems simply by swiping your card at a café or retail store that uses Square — without your direct knowledge or consent.
Square collects a wide range of personal and financial data — including transaction history, device identifiers, location data, government-issued ID, and inferred behavioral profiles — from both merchants and the consumers who shop at Square-powered businesses, even without a direct account relationship. This data may be shared with financial institution partners, service providers, and used for cross-product profiling and marketing purposes, which creates meaningful privacy exposure for everyday buyers. You can submit a data access, correction, or deletion request through Square's privacy rights portal at https://squareup.com/us/en/privacy/request.
