Data ownership

Export anytime. No lock-in.

Your dive history is a training record, trip history, and evidence. DiveOne treats portability as a trust requirement, not a premium feature.

If you have been burned before

Plenty of divers have watched years of logs disappear behind a shut-down app, an opaque sync, or a subscription wall. That is a broken deal: you did the dives, the app held the history hostage. DiveOne is built so that cannot happen quietly — your logbook stays exportable, and data status stays visible instead of silent.

Data ownership

What portability means here

Not a marketing word. A set of concrete paths in and out.

Export your whole logbook
Your history stays portable: CSV for spreadsheets and universal tools, UDDF for portability across the scuba ecosystem.
Bring your existing dives
Import your deeper dives from Apple Health, UDDF, or Subsurface, so the history you already have is not left behind.
Local-first storage
Dive recordings stay on your devices by default. Cloud features are optional and only run with your explicit consent.
Leave anytime
If DiveOne stops being right for you, your history leaves with you. That is the standard we hold ourselves to.

The honest print

  • DiveOne 1.0 is available on the App Store. These pages describe the current release and do not claim features ahead of shipping.
  • Portability is not a paywall lever: the Free tier includes export basics.
  • DiveOne is a logbook, not a dive computer. Nothing here is decompression guidance.
