For help with the Lifestream iPhone app, the Mac app or the Chrome extension, write to contact@lifestream.ing. Say which app, which version, and what happened.
Getting the iPhone app
The iPhone app is a beta on Apple's TestFlight. Open https://testflight.apple.com/join/wA1AwVHv on your iPhone, install TestFlight if it asks, then install Lifestream. Then pair it with your Mac: Lifestream on your Mac shows a code to scan.
Privacy
The iPhone app privacy policy and the Chrome extension privacy policy say what each reads and where it goes.
