If you've shopped around for a budgeting app in the last decade, you've seen the same pitch a dozen times: "Connect your bank in seconds and let us do the rest." It sounds like magic. It's not. Under the hood, that magic is usually Plaid (or a similar aggregator) storing a copy of your online banking credentials and logging into your bank on your behalf. Lemonbudget takes the opposite approach: 100% manual entry, by design. No bank credentials. No aggregators. No screen-scraping. Here's why we made that choice.
1. The security story is uncomfortable
When you "connect your bank" in most budgeting apps, one of two things happens:
- Credential storage. Your username and password are stored (encrypted, usually) and replayed against your bank's website.
- OAuth-style tokens. A better option where supported, but in practice the aggregator still sits between you and your bank, and often sees the full transaction history across every linked account.
Either way, you are trusting a third party with one of the most sensitive credentials you own. When that third party has a bad day — and they occasionally do — you have a problem that reaches far beyond your budgeting app.
2. You're the product when "it's free"
Free budgeting apps have to make money somewhere. Historically, that has often meant selling aggregated, de-identified spending data to advertisers, card issuers, or market researchers. "De-identified" is doing a lot of heavy lifting there — spending patterns are notoriously easy to re-identify.
If an app can see every transaction on every account, it can build a remarkably detailed profile of your life — where you shop, where you travel, what you drink, who you pay rent to. That's a big ask.
Lemonbudget is paid software (40 CHF/year after a 30-day trial). That simple business model means we make money when you find the product useful — not when we squeeze data out of your transactions.
3. Manual entry actually changes behavior
Here's the counterintuitive part: even if bank sync were perfectly secure and perfectly private, we'd probably still recommend manual entry for most people. Here's why.
Automatic imports create a passive relationship with your money. Transactions just appear. You glance at them at the end of the month, feel vaguely bad, and close the tab. Manual entry forces a two-second pause every time you spend — the pause where you remember you have a budget. Most users report that within two weeks of switching, their impulse spending drops noticeably, before any actual budgeting rules change.
It's the same reason cash "feels" different from contactless. Friction, used deliberately, is a feature.
4. "But it sounds like so much work"
This is the number one objection, and it's fair. So let's be concrete. In Lemonbudget, adding a transaction takes about five seconds:
- Tap the + button.
- Type the amount. The category is guessed from your last few transactions.
- Confirm.
Most people do this at the register or when they close their delivery app. Pro users can also snap a photo of a receipt and let on-device OCR pre-fill the fields. For fixed costs like rent, utilities, and subscriptions, scheduled transactions post automatically — you set them up once.
If you're migrating from YNAB, Monarch Money, or a spreadsheet, Pro users can import their full history via CSV, YNAB export, or Monarch export. You don't start from zero.
5. Your data stays encrypted, even from us
Because you enter data yourself, there are no bank credentials anywhere in our system to steal. On top of that, everything you enter is protected at rest with AES-256-GCM encryption — the same family of ciphers used by banks, password managers, and government standards.
When bank sync would make sense
We're not anti-sync dogmatists. Bank sync is genuinely useful in a few scenarios: reconciling an account with hundreds of transactions per month, catching fraudulent charges quickly, or managing business accounts where every penny must match. We may add optional bank sync later for users who want it, via direct bank APIs where supported. But it will never be required, and it will never be the default.
The bottom line
Privacy-first budgeting isn't about paranoia. It's about choosing a tool whose incentives line up with yours. Lemonbudget is a paid app, with no bank access, that encrypts your data at rest and lets you export everything whenever you want. That's the deal. No asterisks.
If that sounds like your kind of budgeting, start the 30-day free trial — no credit card required.
