๐Ÿ›ก๏ธ WHY CALENDAR VAULT?

โœ“ Keep professional and personal life separate
โœ“ Privacy from family members or friends borrowing your phone

• Open Development - Transparent about features and permissions

ADVANCED FEATURES:
FAKE PIN MODE:Create an optional decoy PIN that shows an empty vault. This security feature protects you in coercion scenarios where someone forces you to unlock the app.

BIOMETRIC RECOVERY:
Set up fingerprint recovery with a secret date. If you forget your PIN, tap a specific date 5 times in the calendar to trigger fingerprint authentication.

EXPORT BACKUP:
Export all vault content to a secure folder for backup purposes. Maintain control over your data with manual backup options.

ICON DISGUISE:
Choose from multiple icon styles matching popular OS designs (iOS, One UI, Pixel, MIUI, Oxygen OS, Color OS, EMUI, Windows, Nothing OS, and more). Change the app name to
Calendar, Planner, Agenda, or My Day.

๐ŸŒŸ WHAT MAKES US DIFFERENT?
Most vault apps use calculator or file manager disguises that immediately look suspicious. Calendar Vault provides the most believable cover while delivering a fully functional calendar app. You get real utility plus complete privacy protection.

๐Ÿ“ฑ HOW IT WORKS
1. Download and install Calendar Vault
2. Complete quick onboarding
3. Set your secure PIN (4-9 digits)
4. Start vaulting photos, videos, contacts, and documents
5. Use the calendar for normal scheduling
6. Your vault stays hidden behind the functional calendar
