Offline Evidence Vault Pro is a secure, offline-first Flutter application designed to manage sensitive cases and digital evidence without relying on any server or cloud connection.

The app allows users to create cases, attach photos, videos, and notes as evidence, and organize everything in a clear timeline. All data is stored locally on the device, ensuring full privacy and control.

For security, the application uses an App PIN system and automatically locks when the app is moved to the background or the device is locked. Export options include professional PDF case summaries and ZIP archives containing all evidence files, making it suitable for documentation and record-keeping purposes.
