Curve: sovereignty score and 8 European alternatives

Curve is a consumer payments app that combines a user's existing bank and credit cards into one digital wallet, and it issues its own card. It is delivered as a mobile app and aimed at private customers in the United Kingdom and the European Economic Area. Curve UK Limited is authorised by the Financial Conduct Authority to issue electronic money, and Curve Europe UAB holds an electronic money institution licence from the Bank of Lithuania for EEA customers.

Curve UK Limited is registered in England and Wales with its office in London, so the company is headquartered in the United Kingdom, outside the EU and the EEA. For European customers, Curve Europe UAB in Vilnius issues e-money and cards under a Bank of Lithuania licence, giving them an EU-regulated contracting party. The website does not state where customer data is stored or whether a data processing agreement is offered, so these should be requested before use. Transfers of personal data to the United Kingdom are a point to check under the GDPR.

Why digital sovereignty matters with Curve

Curve is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Curve hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Curve is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Curve together with your other vendors and gives a total score, a heatmap and the main risk drivers.
