theONE Vessel Command Center · JEMS Marine, LLC
Help inside the app
Every screen in theONE has its answer in the app itself: open the menu (☰) and choose Help Center. It covers setting up your boat, maintenance and work orders, trips and tracks, stowage, crew and access, sign-in and your account, and the safety tools. It works offline, at sea, with no signal.
Write to us
Email ops@jems-marine.com. A person reads every message. Tell us what you were doing, what you expected, and what happened instead; a screenshot helps. From inside the app, Menu (☰) → Settings → Send Feedback does the same and can add the last hour of the app’s own log; the screen shows you exactly what will go, and you can leave the log out.
Your account
theONE works with no account. If you signed in and want your account removed, the app does it itself: Menu (☰) → Settings → Account → Delete my account. Or write to privacy@jems-marine.com and we will do it. What we hold, and what deletion removes, is set out in our Privacy Policy.
Safety
theONE’s safety features supplement — they never replace — proper seamanship, official charts and U.S. Coast Guard requirements. In an emergency, call the Coast Guard on VHF channel 16 or 911 first.
