Are you prepared for the unexpected?
I wasn’t.
Recently, I lost people who were very close to me.
They were taken far too soon. The stories were incredibly sad.
What is equally heartbreaking is the chaos they left behind—not intentionally, of course. Nobody knows when their time will come. We all hope it will be much later, believing there will still be enough time to organize our affairs.
I’ve seen their families struggle to find insurance policies, locate savings, access accounts, and piece together important information, only to realize that much of it was lost forever. They couldn’t unlock phones or laptops, access social media accounts or crypto wallets, and they discovered subscriptions and services they never even knew existed.
Endless chaos that only added more pain during an already devastating time.
I don’t want my family to go through that. I don’t want my children to lose access to money, investments, or important documents simply because nobody can access—or even knows about—my accounts, crypto wallets, or financial records.
I don’t want to be lazy. I want to organize my life while I still can—step by step—documenting what matters and securely sharing it with the people who need to know.
I started searching for a platform where I could do exactly that.
It needed to be bulletproof, with top-tier security, because I wanted to store sensitive information there. Google Drive, Dropbox, and Microsoft OneDrive were not suitable for my needs. I wanted a solution where privacy and encryption were the primary design goals. A piece of paper in a safe deposit box wasn’t the answer either.
I needed something that was always accessible digitally, allowing me to manage documents whenever I wanted—modify, upload, or delete them as needed. At the same time, some information should remain private while I am alive. Only after I am gone should those documents be released to my loved ones.
I wasn’t able to find anything like that on the market.
There are some digital vaults available, but I wasn’t impressed by their security models.
That’s why I developed Notify World, a digital legacy and after-life document management application. Not alone, of course. I had help from my amazing team and the talented developers at 1way2cloud. Together, we created a web application and native mobile apps for both iOS and Android.
Notify World consists of three main parts:
1. Document Management
It allows you to create or upload important documents. We provide templates that help guide you on what you should be documenting, such as:
* Legal (my will, power of attorney)
* Business (information about my job)
* Finances (where my money is)
* Insurance (which policies I have)
* Health (my medical information)
* Subscriptions (what I pay for monthly)
* Assets (what I own)
* Debts (who owes me money and whom I owe)
* Logins (usernames and passwords)
* Pet care instructions
* Goodbye letters
…and much more.
2. Trusted Contacts
You can create contacts manually or import them directly from your phone. You can also share them with other users.
Some of these users can become your trusted contacts, who play a very important role. They can help restore access to your documents if you ever forget your password. More importantly, once you are gone, they can initiate the countdown process for releasing your protected documents.
3. Smart QR Tags
You can create QR-code tags for anything you don’t want to lose.
For example, you can create tags for pets (imagine a collar with a QR code for your cat), luggage, bicycles, laptops, children’s backpacks, and much more.
Anyone who scans the QR code will see a description that you have provided, automatically translated into 75 languages. They can leave a message and share their GPS location. Once you receive an email or SMS notification, you can contact the finder and arrange where to meet. You don’t need to make your email address or phone number visible to everyone. Notify World informs you whenever someone scans one of your tags.
You also have a personal tag. This tag belongs exclusively to you and can contain important information such as your blood type, allergies, or emergency medical details. I personally wear mine as a bracelet. If something happens to me and someone finds me unconscious on the side of the road, they can notify my trusted contacts immediately.
You can download and print your QR codes wherever you like. We also offer stickers, bracelets, necklaces, and other accessories that can be ordered directly through the application.
Since launch, the feedback has been incredibly positive.
People are uploading documents, securely sharing information with family and friends, and tagging important belongings with QR codes. Personally, I’ve uploaded my insurance policies, IDs, credit card information, investment records, password manager recovery codes, and much more. I’ve tagged all my bicycles, my children’s scooters, my laptops, and my luggage. If any of them get lost, someone may find them and notify me.
My mind feels at ease now. I’ve organized my assets and continue updating them as life moves forward.
The biggest concern with applications like this is always the same: trust. Why would anyone trust a platform with highly confidential information?
This is where I spent an entire year designing, coding, and testing a zero-trust encryption system, including development of a complex algorithm to cover all the edge cases and cyclic dependency challenges.
Every document is protected by multiple layers of encryption. In simple terms, documents are encrypted using a secret token, which is itself encrypted with your password. Your password is never stored anywhere in the system. Your trusted contacts hold that same secret token, encrypted with their own passwords. The system blocks access to the token until the appropriate time. This means that if you ever forget your password, your trusted contacts can help restore access to your documents. However, if you have no trusted contacts and lose your password, your documents are gone forever. Even platform administrators can never access or read user documents. It is technically impossible.
That is the unique foundation of Notify World.
If you are truly gone, there is no need to provide a death certificate or any other official documentation. Notify World is fully automated. No interaction with a human administrator is required. All that is needed is for all of your trusted contacts to confirm that you are gone. Once they do, a countdown period begins. The length of this period is defined by you—it can be 5, 10, 30, or any other number of days. During that time, Notify World continues sending email and SMS messages to verify that you are truly gone. After the countdown ends, documents marked with the “after-life” flag are securely released to the contacts you selected.
I will soon publish several articles explaining the architecture and security model behind the entire system.
See it for yourself:
Sign up as a Premium user to unlock all features. The first month is free, no credit card is required, and you can cancel at any time.
Where this journey will take us, we’ll see.
Beyond personal use, I can imagine music festivals printing QR codes for their visitors, companies providing Notify World as an employee benefit, or insurance companies offering it to their customers.
The trust issue is still real and will remain a primary concern for many users.
I plan to explore partnerships with reputable organizations in Switzerland, such as law firms, insurance companies, and similar institutions to further strengthen trust and credibility.
Life is unpredictable…
