Money
Accounts, transactions, budgets, recurring bills, debts and investments in one ledger a household can reconcile.
Explore MoneyMoney, notes, important documents and the people they belong to — in a space the household owns, not one person. Who can see what is decided per record.
Asaruma is not in the app stores yet. Every screen on this page is a concept preview with sample data.
Every member keeps their own part. What is shared meets in one space, and what is private stays private.

01
The money sits in one app, the documents in a photo gallery, the plans in a chat group, and the emergency numbers in one person's head. What is missing is not a feature. It is a space the household holds together. Asaruma is built to be that space.
02
Each stands on its own, and all of them follow the same privacy rule.

Accounts, transactions, budgets, recurring bills, debts and investments in one ledger a household can reconcile.
Explore Money
Notes, mind maps, checklists, reminders, goals and dated memories — the things a household has to remember.
Explore Notes
Documents, identity papers and policies encrypted on the device, where approval releases the key itself.
Explore Vault
Members and their roles, the family tree, and a child's growth timeline in one protected space.
Explore Family
One button that tells the household and the emergency contacts something is wrong. On every plan, including the free one.

Two people who share a life do share data — but not all of it, and not forever. In Asaruma every record carries its own setting.
A transaction is open to the household by default, because shared money needs to be seen together. A note and a vault item are private by default, and you can change it per record at any time.

A balance in Asaruma is not a number we store and ask you to trust. It is the sum of the transactions you recorded, and it can be traced line by line. When something does not add up, the cause can be found rather than guessed.
Asaruma does not ask for, transmit or store your internet-banking or e-wallet credentials. Transactions are entered by hand, and that is exactly why a balance can be rebuilt.
The app works fully with no network, and no edit is discarded in silence. Export is open on every plan, including the free one and a lapsed one.
A summary or suggestion from a model always arrives as a proposal you accept, edit or reject. Vault content is never sent to a model.
We are opening Asaruma in stages, so the first households to use it get an app they can already trust.
The privacy rules, the ledger and the Vault come first, before anything else.
A small group of households uses Asaruma and tells us what to fix.

An app that holds what a household runs on: money, notes, important documents, the people in it, and one button for an emergency. All in a space the household owns, with who can see what decided per record.
No, and that is deliberate. We do not ask for, transmit or store your internet-banking or e-wallet credentials. Transactions are entered by hand, and balances are computed from those records.
No. Every record carries its own setting: private, open to the household, or opened to named people. A transaction is open to the household by default; a note and a vault item are private by default.

Someone living alone is still a household. Start on your own and invite the others whenever you are ready.
