Description
Most budget apps want to log into your bank account.
yen-yen doesn't.

You type what you spent, hit save, and get on with your day. That's the whole interaction.

It's built around kakeibo (家計簿), the Japanese household-ledger habit that's been around for over a hundred years. Every entry asks four small questions:

· Did I need it?
· Did I just want it?
· Does it feed something I love?
· Did I see this coming?

Sit with the answers for a minute. That minute is the point.


FREE, FOREVER

Multi-account ledger across cash, banks, cards, and loans. Multi-currency with historical FX so a coffee in Tokyo last March still reads in JPY but totals correctly in your home currency. Budgets and bill reminders. Kakeibo classification on every entry. CSV / JSON import + export. Photo attachments for receipts. Account deletion you run yourself.

No ads. We don't sell your data. We never ask for your bank password.


OPTIONAL ADD-ONS

· Sharing a household ledger with a partner or roommate.
· AI-assisted statement parsing — you paste the lines, you approve every row, nothing auto-saves to your ledger.
· Longer audit retention.
· Priority support.


WHAT YEN-YEN WILL NEVER DO

· Connect to your bank.
· Auto-write AI guesses into your ledger.
· Send push notifications about your spending habits.
· Show ads.


ACCOUNT DELETION

In the app: Settings → Account → Delete. You get 14 days to undo it, after which the data is hard-deleted within 24 hours. The Data Safety form lists the same web flow at https://kensaur.us/yen-yen/account/delete.


HOSTING + PRIVACY

Hosted on Supabase, encrypted in transit and at rest.
