Withings+ becomes required on the Start for Free API plan from October 12, 2026.Details
Withings accounts created after that date will need a membership to share health data with a free-plan app, including apps that are already live.
Accounts created before that date are unaffected, and Enterprise lifts the requirement for specific use cases.

Where your data lives
Two Medical Clouds, two compliance perimeters. HIPAA and ISO 27001:2017 cover both; GDPR and HDS are properties of the France-hosted EU cloud and do not transfer to the US one.
EU Medical Cloud
Hosted in France. The default cloud for Public API and most partner contracts.
- HIPAA compliant
- ISO 27001:2017 certified
- GDPR compliant
- HDS certified — French health-data hosting
US Medical Cloud
Hosted in the United States, for entities covered by HIPAA that need their data to stay onshore.
- HIPAA compliant
- ISO 27001:2017 certified
- GDPR — use the EU cloud for EU residents
- HDS — a French scheme, EU hosting only
Your cloud is set when your access contract is created and cannot be switched afterwards, so pick it against the residency rules your programme answers to. Read the full security and compliance page, or check the API status page.
