Privacy
Your data, your control.
DiveOne is built on the principle of local-first privacy. Your dive logs stay on your devices, not our servers.
Our data principles
Local storage
Your dives are saved directly to your Apple Watch and iPhone.
No accounts
We don't require an account. Your data is tied to your Apple ID.
Portable export
Export your logs to standard formats (CSV, UDDF, JSON) for use elsewhere.
Private by design
We do not track your location or dive activity for marketing.
Where data lives
Apple Watch
Recent sessions and active tracking data.
iPhone
The primary permanent logbook and session history.
iCloud
Optional encrypted backup via Apple Health and iCloud Drive.
DiveOne
We do not host your dive data on our servers.
