Military-Grade Security. Zero-Knowledge Architecture. Complete Transparency.

How DeathNote Works

Every single component part has been built with enterprise-grade infrastructure and military-level encryption with privacy-first principles in mind.

Three-step process overview

1. Sign Up

Easy sign-up with 26 oAuth services like Apple, Google, Spotify, Twitter, Microsoft, and Web3 Wallets (Coinbase, MetaMask, OKX) all with Enterprise Security.

2. Write Messages

AES-256 encrypted messages stored with zero-knowledge architecture. Rich text editor with 11 professional templates, all protected by military-grade encryption.

3. Automatic Delivery

Enterprise message queue with API status verification, retry logic, and comprehensive audit trails. Every action logged with cryptographic timestamps.

Invite Freely, Select Carefully

Database-level Row Level Security (RLS) policies ensure complete data isolation. Distributed locking prevents race conditions and maintains data integrity.

Unlimited Invitations

FREE FOR ALL USERS

Control & Safety: Only contacts you explicitly select will receive your death note. This prevents accidental delivery and ensures your final message reaches only those you intend.

What Happens When You Miss a Check-in

Row Level Security ensures complete data isolation. Every step is logged with immutable audit trails and cryptographic timestamp verification for transparency and accountability.

  1. User misses verification deadline

    Your scheduled check-in period expires without confirmation.

  2. Immediate: Send early warning

    We immediately send you an urgent notification to check-in.

  3. Final warning sent

    A final urgent reminder is sent giving you one last chance to check-in.

  4. Grace period expires

    Your account status changes to expired, triggering the delivery process.

  5. Send death notes to selected recipients

    Your final messages are delivered to contacts you've specifically selected to receive them.

  6. Auto-generate memorial pages

    A respectful memorial page is automatically created for you to honor your memory. Sensitive information is NEVER shared publicly.

  7. Complete audit logging

    Every action is recorded with timestamps for complete transparency and peace of mind.

Important: You have a grace period after missing your initial deadline. Simply click the verification button or link in any warning email to instantly reset your timer and keep your messages private.
