What the Whoop (5.0 / MG) knows about you
Whoop (founded 2012 in Boston by Will Ahmed) makes a biometric-primary, screen-free wrist band with strain, recovery, and sleep AI, recorded in the new biometric form factor and notable as the purest subscription-only model in the cohort, with no standalone hardware sale and annual memberships of $199, $239, and $359 that bundle the Whoop 5.0 and the Medical Grade Whoop MG launched May 8, 2025. It is the load-bearing verified-versus-claimed exemplar through a clean split on its MG device: its ECG is FDA-cleared via 510(k) K243236 on April 4, 2025 as an over-the-counter ECG classifying atrial fibrillation, sinus rhythm, and low and high heart rate for adults 22 and older, but its Blood Pressure Insights feature is not cleared and drew an FDA Warning Letter dated July 14, 2025, in which the FDA held that daily systolic and diastolic estimates are inherently associated with the diagnosis of hypertension and hypotension, meeting the device definition and requiring premarket clearance Whoop never obtained, warning that an erroneously low or high reading can have significant consequences. Whoop argues the feature is general wellness under the 21st Century Cures Act and refused to remove it after the compliance deadline passed, and as of May 21, 2026 the dispute remains unresolved with the feature still live and the warning letter now anchoring a class-action lawsuit, so the medical-grade branding applies defensibly only to the cleared ECG and not to blood pressure. A valuation correction is worth recording: Whoop is valued at $10.1 billion after a $575 million Series G in March 2026, not the stale roughly $3.6 billion figure from its 2021 Series F. Its clinical-validation posture is mixed and contested, with a real ECG clearance and study but a public regulatory finding against its blood-pressure marketing, and the blood-pressure accuracy and wellness classification, the Healthspan longevity construct, and the proprietary Strain and Recovery metrics are disputed or unverified.

What it collects about you
The data this device picks up.
Your body data
Continuously tracks your resting heart rate, HRV, respiratory rate, skin temperature, and blood oxygen, plus sleep and workout data.
Your location
Collects precise GPS and movement data during certain workouts when you grant permission. Classifies location as sensitive personal information under California law. You can disable collection in your phone's settings.
Your body data
Whoop collects heart rate, heart rate variability, sleep duration, respiratory rate, skin temperature, blood oxygen saturation, activity type and duration, plus any additional health information members manually enter; consumer health data includes health conditions, bodily functions, vital signs, diagnostic testing and biomarkers, and derived health information like recovery readiness and risk scores.
Where your data goes
Who else can see it once it leaves the device.
Shared with others
A class action filed in 2025 alleged that Whoop embedded Twilio Segment analytics in its app and that tracker sent biometric data including heart rate, HRV, sleep scores, and recovery metrics to Segment without adequate user consent. Whoop disputed the claim.
Shared with others
Whoop Coach AI is powered by OpenAI. De-identified body metrics go to OpenAI for processing under a contract that prohibits OpenAI from storing or training on the data. Your data still leaves Whoop's systems on each query.
Selling your data
Does not sell member personal data, and has not sold any personal data in the 12 months before its April 2026 privacy policy update.
Shared with others
Shares only de-identified metrics with its AI coaching partner, which operates under a zero-retention, zero-training policy and does not store or train on Whoop member data.
Training their AI
Uses member data to train AI coaching features, but only after removing personal identifiers. The outside LLM partner is contractually barred from retaining or training on any Whoop data.
Selling your data
Whoop does not sell member personal data and does not sell consumer health data to third parties; however, Whoop uses third-party cookies and tracking technologies which may fall under CCPA's broad definition of sale, and aggregated or de-identified data may be shared with any third party including advertisers, promotional partners, and sponsors.
What you can control
Your say over the data it holds.
How long they keep it
Whoop is not covered by HIPAA, which applies to healthcare providers and plans, not consumer fitness trackers. Most US users outside Washington State have no federal law protecting their Whoop biometric data beyond Whoop's own policy, which can change with notice.
Deleting your data
You can delete your AI coaching chat history directly from the app anytime, and access, correct, or delete personal data through a dedicated data management portal.
Deleting your data
Whoop members can delete their personal data upon request including when canceling membership, access and export their data, correct inaccuracies in consumer health data, withdraw consent for future collection or sharing, disable use of health data for personalized recommendations and offers in app Privacy Settings, and opt out of marketing texts by replying STOP.
How long they keep it
Whoop retains consumer health data for as long as necessary to provide services or as required by applicable law; the company takes a variety of physical, technical, administrative, and organizational security measures, maintains access logs tracking who accessed member data and when, but does not explicitly mention encryption in the privacy policy and notes no online activity can be guaranteed 100 percent secure.
