Built a vault app that doesn't trust anyone (including you) — bringing it to Product Hunt June 24

Hey everyone! I'm Alex, solo dev behind IbronEXO — an offline, encrypted vault app for Android, already live on Google Play. No cloud, no telemetry.

The core idea: it has a Decoy PIN. Your real PIN opens the real vault. A different PIN opens a fake vault with believable fake notes. A third PIN wipes everything. Built around the "what if someone forces you to unlock my phone" scenario.

I'm bringing it to Product Hunt on June 24th, but wanted to start a conversation early — would genuinely love to hear what people think. What would make a vault app actually trustworthy to you? What's missing from apps like this that you've used before?
