Peloton is a connected fitness platform from Peloton Interactive. It combines streamed workout classes and an app with its own hardware, such as bikes, treadmills and a rowing machine. The offering covers classes in a range of disciplines, including running, cycling, strength, yoga, boxing, rowing and meditation, and a weekly plan built around personal goals. A membership is required for full access to the content and the hardware features. It is a consumer service: the app and the devices collect the user's fitness data.
Peloton Interactive is based in New York (US) and is subject to US law, including the CLOUD Act. The product page does not say where user data is stored. A European organisation or individual sharing fitness data should expect health-related personal data to end up with a US provider and possibly be processed outside the EU. The company's public pages show no published data processing agreement or GDPR commitment.
