Halo Biometric

Halo Biometric makes medical wearables. Officially that means pelvic-floor monitoring, continuous biometrics and clinical trials, all under FDA review. Unofficially, it makes the most intimate devices ever put in a human body: locks that live under the skin, firmware that decides when you finish, and a keyholder app on someone else’s phone.

Every device ships with terms of use. Every participant clicks I ACCEPT. And every story in this world begins with someone who thought they knew what they were agreeing to.

Stories here are dark, explicit and adult. Consent is always present, often reluctant, and never removed: every participant has a word that ends everything, and it always works. The cost of saying it is the story.

Stories, in reading order

Stories from inside the trials.
