Yes, but it’s not as easy as exporting your data from the Health app. To do so, you have to reach out to WHOOP’s customer care team to request a data dump — which they’ll send to you within 45 days.  My impression of this process is that it only exists because of privacy laws in the European Union (GDPR) and the state of California. Personally, I think that being able to download my own data should be a feature of the WHOOP app that takes just minutes or a couple of hours.
