About this app

What happens to your passwords, contracts, and last words when you're no longer here? Semperia securely stores them in encrypted form and gives them to the people you designate.

THE PROBLEM
Accounts, insurance policies, login credentials, powers of attorney: Much of this is now digital or scattered across folders. If something happens to you, your loved ones will be locked out—at the most difficult moment of their lives.

IT'S THAT SIMPLE
You create your safe. You specify who should receive what. And you check in occasionally with a tap of your finger—your sign of life.

As long as you check in, everything remains secure. And if you don't check in for an extended period, each of your trusted individuals receives exactly what you've assigned them. Nothing more.

YOU SET THE RHYTHM
One day, three, seven, or thirty—you decide how often Semperia checks in. A single tap is all it takes.

If there's no sign of life, nothing happens immediately. A seven-day grace period begins, during which Semperia will warn you several times: on your mobile phone and also via email. Even if your phone is lost or broken, you'll still receive the warning. A single click stops everything.

Access is only granted if you don't respond in any way.

NO ONE CAN READ ALONG – NOT EVEN US

• Everything on your device is encrypted with AES-256-GCM.

• The key consists of six words that only you know. It never leaves your phone.

• What goes to the cloud is an encrypted package – unreadable to us. Servers in the EU. No tracking, no advertising, no data sharing.

• No one can trigger access from the outside. There's no button for that – neither for us nor for anyone else.

WHAT'S INSIDE

• Encrypted vault for access data, documents (with PDF attachments), personal messages, and advance care planning documents.

• Create trusted contacts and assign them to specific entries. Each person receives only what is intended for them.

• Emergency file: an encrypted package with a recovery code and QR code that only that one person can open. Print it out and place it in a folder – it works even without internet access and survives any server failure.

• Unlock via fingerprint. Everything can be deleted at any time.

• Calm, large font. Designed for people who aren't tech-savvy.

TO BE HONEST

Semperia is a tool for planning and organization. It is not a will, not a substitute for a notarized or handwritten document, and not legal advice. For legally binding arrangements, consult a notary, lawyer, or other professional.

Semperia cannot know why you haven't contacted us. It only knows that you haven't responded for an extended period despite multiple warnings. That's precisely what it's designed for – and that's exactly why it warns you so often beforehand.

And most importantly: Keep your six words safe. Without them, no one can access your data – not even us. This isn't a mistake, it's the whole point.

Take precautions today. For those who are important to you.
The digital estate vault: encrypted locally, only you have the key.
