How does this work
The simple logic of Dead Man's Switch in a modern version.
Daily Check-in
Click the "I'm OK" button once every 24 hours. This recharges your battery and confirms you're okay. If you miss a check-in, the system will start counting down.
Emergency Release
If you don't contact us for 30 days, the system will automatically begin the process of transferring the keys to your partner. Your loved one will gain access to the Safe.
Absolute privacy
Zero Knowledge architecture. Data is encrypted on your device, and only you (and your partner after activation) have the access keys. We can't read the contents of your Vault, even if we wanted to. Password hashes are not stored in plaintext on the server.
Security technologies
AES-256 GCM
Military-grade encryption for your vault
Argon2id + HKDF
Key derivation with memory-hard function
Client‑Side Encryption
Your keys never leave your device
What’s next? Our roadmap
We are building a secure infrastructure that will last for decades.
Hardware key isolation
Integration of AWS Nitro Enclaves (or Google Confidential VMs) – seed phrases and encryption keys will be processed in isolated enclaves, inaccessible even to administrators.
Web Worker for cryptography
Moving all key operations to a separate thread – protection against XSS attacks. Your master key will never leave the secured worker.
Open source & audit
We plan to open source key components and commission an independent security audit from top-tier firms.
Pricing & access
The beta version is completely free. In the future, we will introduce a pay‑once model to guarantee eternal storage of your data.

Transfer to a foundation
After development is complete, the code and project management will be handed over to an independent non‑profit foundation. Even if something happens to the creators, the service will continue to operate.
Open source
Critical components will become open source. Any developer can verify the absence of backdoors and even run their own copy.
Endowment fund
Part of the proceeds from paid options will go to a fund that ensures server operation and development for decades to come.
