Relai is a Bitcoin-only app for buying, saving and self-custody of bitcoin, offered in Switzerland and the EU. Users can make one-time purchases and set up recurring savings plans. The app is a self-custodial wallet, so the provider does not hold users' bitcoin. It is delivered as a mobile app by Relai AG, whose holding company Relai Holding AG is also based in Zurich.
Relai AG is a member of the Swiss self-regulatory organisation VQF. Its EU entity, Relai EU SASU in Paris, is registered as a crypto-asset service provider under MiCA with the French AMF. The privacy policy states that personal data is stored and processed on servers in Switzerland, which the European Commission recognises as ensuring an adequate level of data protection. The policy refers to the Swiss Federal Act on Data Protection rather than the GDPR. Ownership is not described on the website. For a European organisation, the Swiss hosting location is a point to weigh against its own requirements.
