Data Ownership: Your Dive Data Belongs to You
We believe dive data should belong to the diver, not the app company. DiveOne is built on this principle from the ground up.
Where your data lives
Dive data is stored in two places: your Apple Watch (raw sensor data) and your iPhone (synced dive logs). There is no DiveOne cloud service. We do not operate servers that store your dive data. If you enable HealthKit sync, Apple manages that data under their privacy policies — not ours.
No account required
You can use every feature of DiveOne without creating an account, providing an email, or signing in. The app works with local data only. No registration wall, no mandatory profile.
Full export, anytime
Export your complete dive history in CSV format at any time from the iPhone app. The export includes: depth profiles, timestamps, water temperature, GPS coordinates, dive duration, and mode. Once exported, the file is yours — send it anywhere, import it into any tool.
Deletion rights
Delete all your data from the app at any time. Since we don't have a cloud copy, deletion is permanent and complete. Your data, your decision.
