What happens if your family needs information only you have?
Store passwords, documents, and final instructions. If you become unreachable, the people you trust receive exactly what they need, automatically and securely.
"Nice setup and really like the safety check in as an avid hiker! Really makes me feel at ease if something happens to me."
for recipients
it leaves your device
Simple to set up. Serious protection underneath.
Get started in under two minutes. The security happens behind the scenes.
Store what matters
Passwords, documents, account credentials, instructions. Anything your family or team would need, encrypted on your device before upload.
Choose who receives what
Assign specific information to specific people. Each person only receives what you intended. Nothing more, nothing less.
Set your check-in schedule
Configure your Lifeline for ongoing protection, or start a Safety Check-In before a hike, surgery, or trip. Each ring has its own timer, contacts, and information.
Automatic delivery when it matters
If you stop checking in, your trusted contacts receive a secure link by email. No Etergis account required. No app to install. They just click and enter the passphrase you shared.
Store anything as text, documents, or files. Only you and the people you choose can ever read it.
We can't read your information. By design.
Everything is encrypted on your device before it reaches our servers. We store ciphertext only. Even with a court order, we cannot produce your data in readable form.
We cannot see your passwords or documents. They're encrypted on your device with a key only you hold.
A breach of our servers reveals nothing. Attackers would find only encrypted data they cannot decrypt.
A subpoena cannot produce your data in readable form. We hold only ciphertext. We have nothing to give.
Your passphrase never leaves your device. Not in transit. Not in our database. Not even in hashed form.
AES-256-GCMAuthenticated encryption. Your information is encrypted and integrity-verified before it ever leaves your device.
Argon2id · 64 MiB · t=3Memory-hard key derivation makes brute-force attacks against your passphrase economically infeasible.
X25519 + HKDFPer-recipient key wrapping. Compromising one recipient's access reveals nothing about anyone else's.
Zero-knowledge serverWe store only ciphertext. No plaintext, no passphrases, no keys. Even we cannot read your information.
For the moments you can't plan for.
You may know the paper version: the "if something happens to me" binder. Etergis is that binder, encrypted, always current, and delivered automatically to the person you chose, only when it matters.
Unexpected hospitalization
Your spouse needs the WiFi password, insurance login, and bank access. Etergis delivers it to them automatically if you can't.
Before a first date
Meeting someone new? Leave the details with a friend the safe way: who, where, when, and what they told you. Start a Safety Check-In; if you don't check back in, your friend gets it automatically. While you're fine, nobody sees anything.
Solo travel & hiking
Start a Safety Check-In before you head out. Pick a timer: 1 hour, 4 hours, 8 hours. If you don't check back in, your emergency contacts are notified automatically.
Family emergency planning
Store everything your family would need in one secure place: account credentials, medical info, important contacts, final instructions.
Digital estate & inheritance
Ensure digital assets, crypto wallets, and important documents reach the right people. No lawyer required for delivery.
Business continuity
Server credentials, vendor contacts, operational procedures. If you're unavailable, your business partner gets what they need to keep things running.
Documenting a workplace problem
When something at work is wrong and you're the one who saw it, keep the record outside the building: a timeline, where the evidence lives, who to call. If anything happens to you, the person you chose receives it. Encrypted until then.
Elder care coordination
Help aging parents organize critical information. Medications, doctors, accounts, legal documents. All accessible to caregivers when needed.
Free to start. Upgrade when you need more.
All plans include end-to-end encryption, check-in monitoring, and automatic delivery.

More ways to protect the people who depend on you.
Same zero-knowledge architecture. New ways to use it.
Safety Check-In
Solo hike? First date? Surgery? Set a short timer. If you don't check in, your emergency info goes to your chosen contact automatically. Available on Personal and Family plans.
Time Capsules
Schedule encrypted messages for future delivery. Birthday letters, anniversary notes, or instructions, delivered on the date you choose. It stays sealed until then, and still delivers if your Lifeline ever fires. Available on Personal and Family plans.
Emergency Keyword Trigger
One word releases everything. Text your safe word to Etergis and your emergency information goes out to the right people, after a short cancel window in case of a mistake. Available on the Family plan.
