Foldernote is a local-first note-taking app that organizes notes into folders.
🔒 Privacy first
• No ad / analytics SDKs, no account signup
• Notes stay on-device — no cloud sync
📁 Folders + Notes
• Organize notes by folder with per-folder sort options (manual / title / date)
• PIN-locked folders with biometric recovery
• Mandalart 3×3 grid notes (for goal-setting and planning)
• Account book folders — monthly budgets with day-by-day income / expense, shared fixed items, per-book currency
• Routine folders — day-by-day 24-hour AM / PM slots, check off with per-day progress; today auto-seeds from yesterday's filled slots
✍️ Editing

🚫 What we don't do (on purpose)
• Cloud sync — backup destination is your choice
• Ads, accounts, sign-ups
• Collaboration / co-editing
Permissions:
• USE_BIOMETRIC — biometric / device-credential auth for folder unlock recovery
• RECEIVE_BOOT_COMPLETED — refresh the home widget after device reboot
• CAMERA — attach photos (images stay in app-private storage, no external send)
• Storage — limited via Android's Storage Access Framework to a folder you pick
