Data Ownership: Your Dive Data Belongs to You

Dive recordings are kept on your Apple Watch and iPhone by default. In 1.0.1, signing in may copy your logbook and attached photos to DiveOne servers; this is off from version 1.0.2. If you enable HealthKit sync, Apple manages that data under their privacy policies.

You can use on-device dive tracking without creating an account, providing an email, or signing in.

Export your dive history from the iPhone app as a CSV summary: one row per dive with date, site, max depth, duration, mode, buddy, and notes. A JSON backup keeps the full records and can be restored in DiveOne. UDDF export is in the app from version 1.0.2. Once exported, the file is yours.

Delete dives in the app. Delete a dive you added on the website in your website logbook. To close your account, use Close account under Account on the website or Delete account in the iPhone app. Self-service closing stops access immediately and schedules deletion after the 30-day grace period. Or email privacy@diveoneclub.com from your account email. We close the account and delete its data within 30 days of your request. Your data, your decision.
