Every family has one person who knows how everything works.
Kinsake makes sure they’re not the only one. Bills, papers, passwords and the how-tos in your head, kept current a minute a day, and handed over to the people you choose if something happens.
Coming soon on the web, for any phone or computer. Free during the beta.
Kinsake
Where does your family’s know-how live right now?
The video of how to relight the pilot light is in the family chat, a few thousand messages up. The bank texts its code to one phone, and that phone has a passcode. The insurance papers are in a drawer nobody else opens.
A binder helps, until the first thing changes.
SamHow do we turn the water off again?
I sent a video last winter
SamWhere?
Water shut-off
Garage, behind the water heater.
Opens with Emergency
Save it once. Find it in ten seconds.
Add the photo or the video you already sent, say the rest out loud, and it lives on the water shut-off, not somewhere up the family chat.
How to reset the Wi-Fi. Where the breaker panel is. How Grandma makes the soup. Explain it the way you would in person, a minute at a time.
Share it with your partner or your grown kids today, or let them ask you for the one you haven’t written yet.

On paper, too
One tap makes a binder on your device: a fridge page for the babysitter, a wallet card, a full binder with room for three holes. Passwords stay out unless you add them.
Export everything, any time, in formats you can open without us.
Everything the house runs on
Nineteen sections in five groups. Each one asks a plain question instead of showing a blank form, and you can take a photo instead of typing. Every section opens with one handover level, and you can move any item to another.

Opened for Maya after the 7-day wait you set. Read-only, and logged.
Not for Maya
This item is in After death, a level you didn’t give her. Opening another level never opens this one.
You see all of it. We see one line.
What we can see
| For | What we can see | Why | For example |
|---|---|---|---|
| Reminders | A title and a date for each reminder | So we can remind you on time | Car registration · Nov 30 |
| Reminder emails and notifications | They carry only that title and date | Car registration · Nov 30 | |
| Your household | Who is in your household and Circle, and each person’s role | So the right people are invited and told | Sam · co-owner |
| Each item’s level, whose it is, when it changed, how large its files are | So a handover releases only what you chose | Incapacity · Alex · 2.4 MB | |
| Handovers | Requests, wait times and confirmations | So we can hold the wait and tell you | Emergency · 24 hours |
| The log of who opened what | So you can read it | Maya opened Emergency | |
| Signing in | Your email address | It’s your account name, and how handover mail reaches you | Your email |
| That you sign in with Google, if you choose Google | So Google can confirm it’s you | ||
| Counting | How many people visit, where they came from, how many households use each feature | To improve Kinsake, on our own servers, without cookies | Never your File, titles or email |
| Everything else | Item details, documents, photos, voice notes, passwords and device codes, For later messages, the call log | Sealed on your device before upload | Sealed |

Hand it over in levels
It isn’t only about dying. A week in the hospital is enough for someone else to need the autopay list.
To begin, you choose your Circle. Your partner shares the whole File. A sister, a friend or an executor gets only the levels you give them: Emergency for doctors, medications, allergies, insurance cards, who to call and where the spare key is; Incapacity for bills, accounts and the house; After death for your wishes and the accounts to close.

- Maya sisterEmergency Incapacity
- Jordan friend, executorAfter death
When someone asks, you hear right away. A trusted contact taps Request access. We tell you at once, again halfway through the wait, and a day before it ends. One tap on I’m OK, in the app or in the email, stops it.
Maya asked to open Emergency
If you don’t stop it, Emergency opens for Maya on Fri, Oct 16 at 9:40 AM. Nothing else opens.
I’m OKThis link stops the request. It can’t open or export anything.
During the wait, nothing opens. You set the wait for each level, and for each person if you like: for example 24 hours for Emergency, 7 days for Incapacity, 14 days for After death. After death also needs a second trusted person to confirm, never the one asking.
- Emergency24 hours
- Incapacity7 days
- After death14 days, then Sam confirms
- For Maya only: Emergency12 hours
When the wait ends, that level opens, and only that level. What opens can be read, not changed. Every opening is logged, and you can read the log. If you stop checking in, we let your Circle know. Nothing opens on its own.

From then on, The Guide is there. The people you chose get a calm checklist for the first days, weeks 1–2, the first month and the first year, with plain words for probate and the rest. It’s free for them, always.
In your own voice
Text tells them what to do. Your voice tells them it’s going to be fine.
Save the voicemail you can’t bring yourself to delete, before the next phone upgrade does.
A question a week, like “How did you two meet?”, answered with a voice note or a few lines.
For later holds messages, voice notes and links for one person, passed on by someone you trust once After death opens. No account needed to read them.

This runs in your browser. Your answers aren’t saved or sent.
Free to start
Kinsake is free during the beta. After it, a Free plan stays, and the handover is never paid.
After the beta, the Free plan keeps one adult, every daily feature, two trusted contacts and 1 GB. Households that need more move to Family, and nothing you’ve saved is deleted either way. Rather pay once? Tick the box when you join.
And more on the way. Join the waitlist to help decide what comes next.
Questions
Who can see my information? You, your partner if you share a File, and the people you choose, each only after a handover you control. Your File is end-to-end encrypted: to remind you, we keep a title and a date, and everything else is sealed on your device. One honest limit: the wait before a level opens is enforced by our server. If someone in control of our server worked together with one of your trusted contacts, they could open that person’s levels early. They could never open a level you didn’t give that person, and we still can’t read your sealed items. A later update will require two trusted contacts to open After death. Read how Kinsake protects it.
Is this a will? No. Kinsake doesn’t replace a will, and nothing in it is legal or financial advice. It keeps the information your family will need, including where your will is kept. An estate attorney can help with the will itself.
What if I forget my password or passphrase? We can’t read your File, so we can’t reset your password or passphrase for you. The Recovery Kit is how you get back in. You print it when you set up and keep it somewhere safe.
How do I sign in? With Google, or with your email and either a password or a 6-digit code. If you use Google or a code, you also set a passphrase that opens your File. Where your device supports it, a quick face or fingerprint check opens it too.
When does it launch? We’re building it now, starting on the web, so it works on iPhone, Android and any computer. Everyone on the waitlist gets an email the day the beta opens, and the beta is free. An iPhone app comes later.
Does it work on my phone? Yes, in any modern browser. Take photos of documents with your phone’s camera instead of typing. On iPhone, add Kinsake to your Home Screen to get notifications.
Do I have to upload anything? No. You can keep your File only on this device, for free, and export it whenever you like. Turn on sync when you want your partner in, reminders by email, or a handover.
Can my partner and I share one File? Yes. Your partner is a co-owner and sees everything. Each item belongs to one of you or is marked shared, so a handover about one of you opens only that person’s items and the shared ones.
What happens if I stop opening the app? If you turn on check-ins and go quiet for longer than you chose, we remind you once, then let your Circle know so someone checks on you. Nothing opens on its own. Away mode pauses this while you travel.
We just lost someone. Can Kinsake help? Yes. When the beta opens, The Guide will be free even if nothing was set up beforehand, and you’ll be able to read it without an account. It walks through the first days, weeks 1–2, the first month and the first year. It’s general information, not legal or financial advice.
Do you use my data for ads or AI? No ads, and no third-party trackers or analytics. We never sell your data, and it’s never used to train AI. We can’t read what’s in your File anyway.
What if Kinsake shuts down? If Kinsake ever closes, we’ll tell you at least 90 days ahead. Until the last day you can export everything in formats that last without us: a PDF binder, CSV and plain-text files, and a ZIP with your documents, photos, voice notes and videos. Anything kept only on your device keeps working after we close. Then your data on our servers is deleted. It will never be sold.
Why I’m building Kinsake
I grew up in my grandparents’ home and lived with them until I was 18, when I left for college far away. I remember the sườn ram, caramelized pork ribs, from their kitchen. I remember my grandmother scolding me when I did something wrong, words I didn’t appreciate until I was grown. And I remember my grandfather trimming the hedge along the fence, then splitting a coconut for me to drink.
None of it felt like something to keep. It was just everyday life, and I assumed it would always be there. By the time I understood what those days were worth, and knew how to build something that could have saved them, my grandparents were gone. What I wish I had kept most are their voices and pictures of them. It’s one of the regrets I carry.
Today I’m the one in my home who keeps track of how everything works: the Wi-Fi password, the account numbers for the power and water bills, where the hammer, screwdrivers and pliers live. Your list is probably different. But a lot of us are that person for our families, and a lot of us want to hold on to what our parents know. The replies to a Threads post about an “in case of death” folder were full of people who feel the same way.
Grief and loss come to every family. What we can keep are the things money can’t buy back: a voice, a face, a story, the way something is done. That’s why I’m building Kinsake.
