Everything You Need to Know
Common questions about Open Drone Logbook, DJI log analysis, and privacy.
Is Open Drone Logbook really free?
Yes, Open Drone Logbook is completely free and open source under the BSD 3-Clause license. There are no subscriptions, premium tiers, or paywalls. All features are available to everyone at no cost, forever.
Which drones and flight logs are supported?
Open Drone Logbook supports all DJI drones that generate .txt flight logs including DJI Mini, Mavic, Air, and Phantom series. It also supports Litchi CSV exports with automatic metric/imperial unit detection.
How is this better than Airdata UAV?
Unlike Airdata UAV which requires expensive subscriptions ($75/year) and cloud uploads, Open Drone Logbook is 100% free, stores all data locally on your device, and is open source so you can verify privacy. You get similar features including 3D flight replay, telemetry analysis, and export capabilities without any cost.
Is my flight data private and secure?
Absolutely. All your flight data is stored locally on your device in a DuckDB database. Your logs never leave your computer, ensuring complete privacy and data ownership. Unlike cloud-based alternatives, you're not uploading sensitive flight information to third-party servers.
Why this is sending HTTP requests to DJI servers?
The newer versions of the log files are encryptred and require fetching the decryption keys from DJI servers to decode the flight data. This is done locally on your device and the decrypted data never leaves your computer. This allows Open Drone Logbook to support the latest DJI drones while still ensuring your privacy.
Can I export my flight data?
Yes! Open Drone Logbook supports exporting to multiple formats including CSV, JSON, GPX (for GPS tracking apps), and KML (for Google Earth). You can also backup your entire database and restore it on any platform.
What platforms are supported?
Open Drone Logbook runs on Windows, macOS, and Linux as a desktop application. You can also deploy it as a self-hosted web app using Docker on any server or NAS device.
