Show HN: Word Maze – Secure Folder with Flip-to-Hide and Built-In Viewer and Cam

1 Zifnap 0 8/20/2025, 11:22:42 AM

Hi HN,

I’ve been working on Word Maze – Secure Folder, a mobile app designed to keep files private without pushing them to system galleries or the cloud.

Some of the core features:

- Flip-to-Hide → Instantly switch to a maze game screen in unexpected moments. - KillSwitch → Wipe data safely if needed. - Built-in Viewer → Open photos, videos, and audio directly inside the app — nothing leaves the sandbox. - Custom App Icons → iOS fully supports multiple app icons; Android has partial support. - In-App Camera → Photos/videos taken stay in the app, never exported to the system gallery.

Tech-wise, the app is built mainly with Flutter, but for performance (esp. thumbnails, memory handling), I had to drop down into Kotlin/Swift. iOS felt smoother for media handling, while Android required more native workarounds to avoid OOM issues.

I’ve tried to build this as carefully as I could, but I may have missed things. If you spot a better approach, or think of another privacy feature worth adding, please let me know.

I’d be happy to answer any questions.
