The security of your data

Sejf Życia was built to give you full control over your documents.

Protection mechanisms

Modern mechanisms that protect your data

Every mechanism in Sejf Życia - from encryption to privacy by design - exists so you can be certain your information is truly yours alone.

Encryption

We use multi-layered encryption based on modern standards such as AES-256 and RSA-2048, with keys generated locally by the user. Every document is secured individually, and decryption happens only on your device.

Your individual key

Each user generates a personal cryptographic key on their own device, without any server involvement. The key is derived from a unique behavioural pattern, giving a level of security traditional cloud systems can’t match.

Blockchain

Notarising a document in a public blockchain (storing its hash) guarantees that the authenticity of information retrieved from the safe can be confirmed in the future. We do this for your loved ones, for when you are gone.

Zero-knowledge proof

We use advanced identity-verification methods before anyone tries to access the data in a safe. We block even encrypted data from being downloaded if an unauthorised person attempts it.

Security by design

Sejf Życia’s architecture is built on the principle of security by design and industry best practices (e.g. OWASP ASVS). Our goal is not only to protect your data, but to build a safer digital environment for everyone.

Privacy

Your right to privacy is a pillar of our company. That’s why your data is never used for profiling or training artificial intelligence - unlike Big Tech solutions. We believe technology should serve people, not analyse them.

MFA

We follow best practice and require multi-factor login to protect your account. Others encourage MFA - at Sejf Życia it’s the default, active from the moment you create your account.

Procedures

In competing systems data is protected by procedure. At Sejf Życia, technology protects your data from the very start - we never have access to a safe’s contents. We apply procedures across the whole organisation to deliver the most secure product possible.

A unique key

At Sejf Życia, only you hold the “key to the safe”. You create it on your phone or computer from your individual behavioural pattern. The result? Even if someone reached the infrastructure, they would see only unreadable, encrypted data. We generate the user key locally using strong entropy, then protect it with a KDF mechanism (salted, many iterations). We encrypt user data symmetrically (AES-GCM) and protect session keys asymmetrically (RSA). We use a verifiable key-sharing scheme built on zero-knowledge proof.

Legacy Contact

You can designate a Legacy Contact (up to four) for your account, who will gain access to documents you choose, in strictly defined situations (for example after your death). The system sends notifications and requires verification to prevent abuse. Everything happens transparently, with full event logging. The account guardian helps authorised people reach the information you leave behind.

Integration with the PESEL registry

If something happens to you (because Sejf Życia is also there just in case), we check whether you are all right in the government PESEL registry. Only when your PESEL is marked as “deceased” do we start the procedure to release information to the people you named. If you don’t give us your PESEL number, we instead check your activity in the system and confirm with your designated Account Guardians whether you are alive.

Risk scenarios

We regularly test recovery procedures, maintain incident-management mechanisms and monitor the security of ICT service providers. Our processes are designed for continuity even in crisis situations.

HIPAA

We are not formally subject to HIPAA, but we deliberately implement its requirements for protecting sensitive information. Sejf Życia runs access controls, continuous event monitoring, auditing of administrative actions and processes that ensure the immutability and confidentiality of user data.

NIST and Post-Quantum Cryptography standards.

NIST / PQC

We follow NIST guidance on Post-Quantum Cryptography (PQC), preparing the system for the era of quantum computers. Data stored in Sejf Życia is encrypted with algorithms designed to stay secure even against future cryptographic threats.

Compliance with KNF and UOKiK requirements.

KNF / UOKiK

Sejf Życia meets the highest standards set by Poland’s UOKiK and KNF for processing regulated data covered by banking and insurance confidentiality. We store data on a durable medium - guaranteeing immutability, integrity and availability together with proof of authenticity.

OWASP

In designing and developing Sejf Życia we follow OWASP ASVS 5.0 - the international application-security standard. Our code is systematically analysed for vulnerabilities, and security checks are built into every stage of development.

Insurance policy

Sejf Życia’s security is not only technology, but also responsible business conduct. Safe & Trust holds a civil-liability insurance policy for its operations, covering IT as well.

The policy is further confirmation that we treat security, stability and operational responsibility as a core part of how we work. Insurance does not replace our technical and organisational safeguards - it complements our risk-management model.
