Locky - NFC vault, expense tracker and subscription manager

🔒 Locky – Turn your physical cards into smart digital keys (NFC Wallet + Expenses Manager) Hey Guys! 👋 I’m building Locky, a privacy‑first NFC wallet and expense tracker that turns your physical cards into smart digital keys. It uses a hybrid model: card data stays encrypted on your device, while expenses + subscriptions sync to the cloud so you can access them anywhere. What it solves I wanted a simple way to attach secure notes, reminders, and expense info to the cards I already carry without giving up privacy. So I built Locky. ✨ Key features 📲 Instant NFC Scanning → Tap any NFC card to identify it instantly 📝 Encrypted Notes → Store PIN hints, reminders, or private notes per card 🔒 Local‑only card data → Card info always encrypted in local storage 🔄 Subscription Manager (NEW!) → Cloud‑synced across devices 💸 Daily Expense Tracker → Auto‑sync to the cloud for access anywhere 🛡️ Strong Security → AES‑256 encryption + Biometrics/PIN 🎨 Hand‑crafted UI → Dark mode, clean and fast ⚡ Zero latency → Ultra‑fast scan and retrieval 💡 Use cases Save secure PIN hints for each card Track last used card details Add emergency info to your ID badge Keep expenses organized privately Clean up your wallet digitally If you care about privacy + utility, I’d love your feedback.
