How it works

SeaCert is designed for real-world use at sea:

• Fast access to documents

• Simple, structured interface

• Full control over your files

Privacy

• No account required

• No data collection

• No remote storage by default

• All data remains on your device

Optional support (Ko-fi) opens in your browser and does not affect app functionality.

Android
