Your logbook stays on your own device. We cannot see it. It works offline, on the boat too. Use Back up regularly, and use Restore to move everything to a new phone.
Moving to a new phone? 1) Tap Back up and send the file to yourself (WhatsApp, email or Drive). 2) On the new phone open pinkwhaleclub.com/logbook/, tap Restore and choose the file. All dives, photos and settings come across.
