An expense app without linking your bank account

Many personal finance apps ask for your banking credentials to import transactions. If you don't like the idea, you're not paranoid: an expense app can work perfectly well — often better — without touching your account. Here's why, and what to look for.

Why avoid bank linking

Privacy: your bank transactions tell everything about you — where you go, what you buy, how much you earn. The fewer parties see them, the better. An app without linking has nothing to leak.
Cash and mixed payments: bank syncing doesn't see cash, meal vouchers, or a card from another circuit. Manual tracking covers everything by definition.
No account, no strings: if the data lives on your phone, you don't depend on anyone's servers and you don't have to create yet another account.

The hidden advantage: awareness

There's also an effectiveness reason, not just privacy. Automatic imports make you a spectator of your spending: you look at it afterwards, in bulk, when it's already done. Manual logging makes you a participant: the act of recording $28.90 of shopping the moment you spend it creates the good kind of friction, the kind that after a month makes you say "no, I don't need this". It's the same principle by which writing by hand helps you remember.

The classic objection is "but logging by hand is a chore". True ten years ago: today, done well, logging costs two seconds — and with a widget, one tap.

What to look for in an app without bank access

Logging in a few seconds (if it's slow, you'll abandon it: it's the only real risk of the manual method);
Widgets or shortcuts for everyday expenses;
Automatic categories, a monthly budget and statistics;
Data on your device with backups/exports you control;
Recurring payments for subscriptions and salary, so the "manual" part stays minimal.

Frequently asked questions

Is an app without bank linking less accurate?

No, quite the opposite: it also covers cash and payments outside your main account. It only requires the consistency of logging — which with widgets and recurring payments comes down to a few seconds a day.

What happens to my data in Crena?

It stays on your device. Crena requires no account and doesn't collect your transactions; backups and exports are under your control.

What if I change phones?

Make a backup of your data from Crena and import it on the new iPhone: the backup file is yours and contains everything.
