SeaTime is a personal record locker for merchant mariners. It is not the U.S. Coast Guard, NMC, or an employer system.
You are responsible for the accuracy of sea time, discharges, and papers you enter or digitize. Always check extracted voyages against the original letter before you file an MMC application. SeaTime does not certify sea service.
Use the app for your own service record and papers. Do not upload documents you are not allowed to copy. Do not use SeaTime to impersonate another mariner.
The app is provided as-is. Offline logging works on this device even if the network is down. Features that read paper or back up to the cloud need a connection and may be unavailable.
In-app Premium limits (unlimited entries, backup, extra reports) are product features. Paid Card payments are processed by Stripe when the publisher connects a Stripe account. Paid App Store or Play billing is separate and only applies if a native store listing is submitted. Clearing the device removes local preview Premium; a paid Stripe subscription stays on the signed-in account.
SeaTime is not liable for denied credentials, missed renewals, or lost local data. Keep paper originals and a backup of anything you would need for an NMC packet.
