# Just In Case — Digital Legacy Platform

> What happens to your passwords, crypto wallets, and digital accounts when you're gone?

Just In Case is a military-grade encrypted vault and digital legacy platform with a 5-level Dead Man's Switch. It ensures your most important information reaches the right people — automatically — when the time comes.

## Core Features

### Encrypted Vault (AES-256, Zero-Knowledge)
- Store passwords, documents, photos, and sensitive data
- AES-256 encryption — same standard used by governments and military
- Zero-knowledge architecture — even we can't read your data
- Biometric unlock (Face ID / Touch ID)

### 5-Level Dead Man's Switch
A progressive escalation system that prevents false triggers:
1. **Level 1** — Email reminder
2. **Level 2** — Push notification
3. **Level 3** — SMS alert
4. **Level 4** — Automated phone call
5. **Level 5** — Final trigger: vault contents delivered to designated heirs

The switch monitors your activity. As long as you check in, nothing happens. If you become incapacitated, the system automatically escalates and eventually delivers your legacy.

### Heir Management with Shamir Secret Sharing
- Designate multiple heirs with different access levels
- Shamir's Secret Sharing splits your master key into N shares where K shares are needed to reconstruct

- Heir confirmation via secure link

### Voice Testament
- Pre-record voice messages or write custom scripts
- System automatically calls your heirs via phone when the Dead Man's Switch triggers
- Supports multiple languages: English, Chinese, Japanese, Korean, Spanish

## FAQ

### How is Just In Case different from a password manager?
Password managers store your passwords but don't solve the inheritance problem. When you die, your family can't access your password manager either (master password + 2FA). Just In Case adds a Dead Man's Switch that automatically delivers your information when you can't.

### What if I just forget to check in?
The 5-level escalation system prevents false triggers. You'll receive an email, then a push notification, then an SMS, then a phone call — over a period of days. Only if you fail to respond to ALL five levels does the switch activate.

### Can you read my data?
No. Just In Case uses a zero-knowledge architecture. Your data is encrypted on your device before it leaves. We never have access to your encryption keys.

### What happens if Just In Case goes out of business?
Your encrypted vault is stored on Google Cloud with redundant backups. We have a continuity plan that includes open-sourcing the decryption tools if the service ever shuts down.

### Is it legal?
Yes. Just In Case is a tool for authorized estate planning. You are granting explicit permission for your heirs to access your information. This is similar to including digital assets in a legal will.
