The Last Will

ZKidz Dev LLC

About this app

The Last Will is a fully private, offline vault for managing your final wishes, important documents, and sensitive information. No accounts. No cloud. No servers. Everything stays on your device, protected by military-grade encryption.

YOUR LEGACY, YOUR CONTROL

Planning for the future shouldn't mean trusting your most sensitive information to yet another cloud service. The Last Will keeps everything on your device — encrypted with AES-256-CBC and a key derived from security questions only you know the answers to.

WILL CREATION MADE SIMPLE

Create comprehensive wills in five guided steps:
★ Add your personal information
★ Name beneficiaries with contact details
★ List and allocate your assets
★ Record final wishes and directives
★ Review everything before saving

Manage multiple wills for different purposes — primary, living will, pet care instructions, or any scenario you need.

ENCRYPTED VAULT

Store all your sensitive information in one secure place:
★ Passwords and login credentials
★ Bank account details
★ Insurance policies and documents
★ Property deeds and legal documents
★ Safe combinations and access codes
★ Personal notes and instructions

Every item is individually encrypted before being stored in the on-device database.

SECURITY YOU CAN TRUST

★ AES-256-CBC encryption (the same standard used by governments)
★ PBKDF2-SHA256 key derivation with 100,000 iterations
★ No passwords to forget — unlock with personal security questions
★ Optional biometric authentication (fingerprint / face unlock)
★ Encrypt-then-MAC verification (HMAC-SHA256)
★ Keys are cleared from memory after each session
★ Zero network permissions — the app cannot send data anywhere

SHARE WITH LOVED ONES

When the time comes, share your encrypted will with family members:
★ Export as a secure .mlw file with independent encryption
★ Share via email, messaging apps, or any method
★ Each export uses its own encryption key
★ Recipients answer the same security questions to decrypt

NO ACCOUNTS. NO SUBSCRIPTIONS.

One purchase. No recurring fees. No account creation. No email required. Your data is yours — we never see it, store it, or have access to it. Period.

WHY THE LAST WILL?

Most people put off planning for the future because it feels overwhelming — or because they don't trust digital tools with their most private information. The Last Will changes that. It's simple enough to use in an afternoon, and secure enough that your information never leaves your hands.
