Your bank password
is none of our business.
Paste a statement below — it runs in your browser. Nothing is uploaded, and we never ask for online-banking credentials.
Most budgeting apps open with the same request: hand over your online-banking credentials so an aggregator can scrape your accounts. It’s convenient, until it isn’t — broken connections, duplicated transactions, and a third party sitting between you and your bank forever.
yen-yen doesn’t connect to your bank at all. You either log spends as they happen — a few seconds each, which is the habit doing its work — or paste a statement and approve the draft entries before anything is saved.
That one decision simplifies everything else. There are no credentials to leak, no aggregator to trust, and no mystery rows appearing in your ledger that nobody in the household remembers.
(It also means the app works the same in Japan, Thailand, or anywhere else — no waiting for your bank to be “supported”.)
The four-question habit is what makes the manual moment worth it.
Questions people ask about going bank-free
- How do I get transactions in without connecting my bank?
- Two ways: type them in as you spend (a few seconds each), or paste a chunk of your bank or card statement and let the import assistant turn it into clean entries you review before saving.
- Is manual entry actually sustainable?
- For most people, yes — because the point of the four-question habit is the moment of noticing, not the completeness of the data. A statement paste once a week fills any gaps.
- What data does yen-yen store?
- The entries you create, the account names you choose, and your preferences. No bank credentials, no aggregator tokens, no third-party data brokers. The full detail is in our privacy policy.
- What happens if I stop using the app?
- Export everything from settings, then delete your account. Nothing lingers with a screen-scraping middleman, because there never was one.
