Privacy posture
Local-first professional records.
Your dive history, certs, and scanned documents are work records. Most of the app works without an internet connection, and core records stay on your device unless you choose to export, back up, print, or share them.
Important: HagaLog is a personal professional record-keeping tool. It does not replace employer-required dive sheets, official regulatory submissions, medical or legal advice, or certified legal record systems.
