Privacy

This site collects one thing: the email address you give us when you request early access. It is stored privately, used only to send your invite, and never shared or sold. The site sets no cookies and loads no third-party analytics or advertising scripts.

The interactive demo on the home page runs entirely in your browser. Nothing you do in it is recorded or transmitted.

Every email from Delta is written and sent by a person. Reply to any of them, the invite included, and ask for your address to be removed; it will be deleted.

The app's full privacy policy, covering training data, Apple Health, sync, coached invites, and the Coach, publishes with the app's release. The commitments it will formalize are the ones this site already states: your training data lives on your device first, readiness signals never leave your phone, body data never reaches a trainer, and nothing is sold.
