What to Look For

Key criteria when evaluating dead man's switch services:

• Encryption: Is it end-to-end? Zero-knowledge? What algorithm? • Check-in flexibility: How configurable are intervals and reminders? • File support: Can you attach files or just text? • Recipient management: Multiple recipients? Different content per recipient? • Privacy: What data is collected? Is anonymous registration possible? • Reliability: What happens during service outages? • Pricing: Free tier? Per-vault pricing? Subscription?

Service Comparison

ZeroLatch: AES-256-GCM client-side encryption, zero-knowledge architecture, anonymous registration, configurable intervals, file attachments, multiple recipients, free tier available.

Google Inactive Account Manager: Sends data to designated contacts after inactivity. Not a true dead man's switch — limited to Google data. No encryption beyond Google's standard. Free.

AfterVault: Dead man's switch with encrypted storage. Server-side encryption. Requires email registration. Paid service.

Dead Man's Switch (deadmansswitch.net): Simple email-based dead man's switch. No file support. No encryption. Free tier with limitations.

Why ZeroLatch

ZeroLatch differentiates through zero-knowledge encryption (the service literally cannot access your data), anonymous registration (no PII required), client-side AES-256-GCM encryption, file attachment support, and a purpose-built dead man's switch mechanism with configurable heartbeat intervals.

For users who prioritize privacy and security above all else, zero-knowledge architecture is non-negotiable.
