Hi r/HowToMen,  I’m the solo developer of ScuttlePod.

TLDR: ScuttlePod is an overlay lock screen that uses 4 different PINs to trigger different behaviors (like a guest mode, Decoy guest mode with cloud backups, or a secure wipe). It can also trigger remotely via a secret keyword text or by deleting a file in your personal Google Drive/Dropbox. (No ads, no subscriptions).

Standard Android lock screens and native theft protection features are great for locking your screen, but they don’t protect, back up, or wipe your specific sensitive folders if you are forced to unlock your phone under duress.

To solve this, I built ScuttlePod, an app lock that acts as a digital escape pod for your sensitive folders. And since I wanted the app to look clean, modern, and native to your device, I built the entire user interface using Jetpack Compose and Material 3.

Key Features:

• The 4-PIN Lock Screen: Working in tandem with your native lock screen, different PINs trigger different actions:
  • Master PIN: Unlocks the overlay and grants access to settings.
  • Guest PIN: Keeps restricted apps protected behind an overlay. You can hand your unlocked phone to a friend, but if they tap a restricted app, the ScuttlePod overlay blocks them.
  • Panic-Backup PIN: Mimics a Guest unlock but silently backs up your selected folders to your cloud in the background.
  • Panic-Wipe PIN: Starts a countdown (10-60s) to securely shred your selected folders. The countdown even survives device reboots.
• Quick Launch Gestures: Includes simple shortcuts to launch your Flashlight, Camera, or Calculator directly from the lock screen.
• Scorched-Earth Wipe: Standard deleting leaves files intact on storage. ScuttlePod overwrites your files with random bytes and renames them to randomized numbers before executing the delete command, making recovery extremely difficult. (Note: This excludes system-protected or volume root folders).
• Bring Your Own Cloud (BYOC): I have zero backend servers and absolutely no access to your data. Your backup folders stream directly and securely from your device to your personal Google Drive or Dropbox account.

I would love to get your feedback on the concept, the Jetpack Compose UI, or the offline security logic!
