Local first

The mission file stays with the mission

CAP Defender Logbook^™ stores every mission in data/logbook.db on this computer. There is no signup and no remote account. A saved pack can be copied to another machine and imported. Full backup and restore live in Settings.

Logs that include mission activity should be kept with the mission file per CAPR 100-1 and CAPR 10-2. Default time is Zulu. Note the time zone on the first line of each day, as CAPF 110 requires.

This desk is for Civil Air Patrol, a volunteer nonprofit. Packs are a modest $1.00 USD each for Windows, macOS, and Linux — not the $19 Moonraker Logbook^® station price.
