Payplug is headquartered in Paris, France, and is a subsidiary of Groupe BPCE, one of France's two largest banking groups. All payment data is processed under French and EU financial regulation with GDPR-compliant infrastructure and dedicated French customer support.
Why choose Payplug over Square?
The decisive argument is data jurisdiction. Square is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Payplug removes that overhead. As a France-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
