About this app

"What do you want to do from now on?"

"Korekara Hiyori" begins with this question.

Many people become apprehensive when they hear the term "end-of-life planning."

"But I'm still healthy," "It's bad luck to think about that."

It's also difficult for family members to bring up the topic.

"Will they want me to die soon?"

That's why Korekara Hiyori changed the order.

■ Just one question per day

Only one question appears on the screen.

"What was your favorite place as a child?"

"Is there anywhere you'd like to visit in the future?"

"What is the most important thing to you right now?"

Initially, it's just about memories and the future.

As you answer, it gradually progresses to topics like daily life, finances, and what to do in case of an emergency.

You don't need to write everything at once.

If you press "Answer later," the question will reappear at a later date.

■ Taking care of worries will lighten your burden from now on.

Where do you keep your bankbooks? Do you have insurance? Who is your family doctor?

Getting your thoughts out of your head makes you feel lighter.

Organize not "just in case," but "for the future."

This is what Korekara Hiyori is an app for.

■ Together with Family

You can invite family members who live far away.

What you write will also appear on your family's screen.

Family members can also send questions like, "I want to ask about this."

Things that are difficult to ask face-to-face can be asked through the app.

As you write more, your family will receive a notification saying, "I've written it down."

What you wrote is not notified. The contents are for them to open and view.

■ Writing is Free for Everyone

Answering questions, copying documents, and inviting family members are all free.

There are no limits on the number of entries.

You only pay for one thing.

**This is to ensure that your family can view the contents in case of an emergency.**

If just one family member registers,
the service will extend to the entire family. Individual payments are not required.

You might think, "I don't want to burden my children."

However, for your family, this is the greatest peace of mind.

■ Documents can be registered simply by taking a photo.

Insurance policies, pensions, and bank documents can be registered simply by taking a picture with your camera.

AI reads and organizes the company name, type, contact information, and renewal date.

You will be notified when renewal is approaching.

Even contracts that don't involve paper documents (online banking, subscriptions, cryptocurrencies, etc.)

can be registered by answering just two questions.

■ Procedures are also included.

The procedures that families actually follow for banks, securities, insurance, pensions, mobile phones, etc., are summarized.

None of the deceased's PINs or passwords are required for any of the procedures.

All that is needed is documentation proving you are an heir.

This is also clearly stated.

▼ Our Commitment to Security

■ Zero-Knowledge Design (End-to-End Encryption)
Everything you write is encrypted and saved on your device.
The key to decryption resides only on your device and is not sent to the server.
Even we, the operators, cannot view the contents.

■ We Do Not Store Your PIN or Password
There are no input fields for this information.
The system is designed to prevent accidental entry.

■ One-Hour Grace Period for Information in Case of Emergency
If we cannot contact you, your family can access the necessary information for the procedure.
However, you have one hour's grace period after making a request, during which you can cancel at any time.
Upon receiving a request, you will immediately receive a notification on your device.
The determination is made using the server's clock, so changing your device's time will not speed it up.

■ AES-256 Encryption and Tamper Detection
We encrypt using a method also used by financial institutions,
and constantly verify that the data has not been rewritten.

■ Biometric App Lock
You can require fingerprint or facial recognition when opening apps.

■ About Fees

All note-taking is free.

Answers to questions, future plans, registration of important documents, inviting family members.

There is no limit to the number of entries.

Registration is only required to view the contents of "Money Matters, Digital Assets, Important Documents, Inheritance and Funeral, and Last Words" written by your family.

The person who wrote it decides when it can be viewed.

One family member's payment covers the entire family.

・Korekara Hiyori Premium (Annual) 10,000 yen per year / Automatic renewal every year
・Korekara Hiyori Premium (Monthly) 1,000 yen per month / Automatic renewal every month
