Your data
Your log lives on your device.
No account to log or plan, no connection needed on the boat, and nothing leaves your phone until you choose. Sync is something you switch on, never a requirement.
No ads. No selling your data. Open export, always.
Local-first
Every dive, plan and piece of kit lives in a fast database on your device. There’s no sign-up wall and nothing to time out at sea. The app is whole and complete with nothing but your phone.
Sync, in layers
Three ways to keep your dives.
Stay entirely on-device, mirror through a cloud you already own, or run full cross-device sync through the ScubaOS server. Each layer is optional; each is honest about where your data sits.
When you do share
You decide exactly what’s shown.
Sharing is per-dive and deliberate. Choose who sees it and how precisely its location appears, and trust that the boring-but-important details, like the GPS buried in a photo, are handled before anything is uploaded.
- Public, followers-only or private, per dive
- The exact site is fuzzed to a rough area, or hidden entirely
- Photo location data stripped before upload, every time
The promise
Private by default, and it stays that way.
There’s no surveillance business model hiding behind this dive app. ScubaOS makes its money from divers who choose to pay for more, not from your data.
Keep your dives, your way.
Start fully on-device for nothing. Add your own cloud, or full cross-device sync, the day you want it.
