Common Questions
Does Halyard work offline?
Yes. Core reference, composer, decode, quiz, and bundled audio/images work offline.
Is Halyard an official marine authority?
No. Halyard is a training and reference app. For real marine operations, follow current official publications and local authority instructions.
Why does the app ask for Photos access?
Only when you choose to save a generated flag-hoist image to your photo library.
