Common Questions
Does the app need an account or subscription?
No. It is a one-time-purchase app with no account, advertising, analytics, or in-app purchase.
Does it work offline?
Core features and bundled reference data work on device without a developer-operated service.
Where is my information stored?
Your selected-log summaries, parsed records, evidence notes, and display preferences remain in the app's local storage.
How do I remove local data?
Use available delete or reset controls. Removing the app removes its local container, subject to backups you control through Apple.
What are the limits?
The app is a log-analysis aid, not a primary navigation instrument. Use approved navigation equipment and current official information underway.
