Lumy for everyday household spending

An expense tracker that never asks for your bank login

Capture the purchases that matter without handing over bank credentials or relying on a bank feed.

Linking a bank account is the default in most budgeting apps, and it is exactly what many people will not do: they do not want to give banking access to a third party, their bank is not supported, or a large part of their spending is cash. Lumy has no bank connection at all. The trade-off is honest, because you record expenses yourself, so the app is designed to make that take seconds rather than an evening.

How it works in Lumy

  1. 1

    Type it or say it

    Add an expense in the form, write it in the chat, or say it out loud; the AI turns a sentence like "groceries 42" into a categorized transaction.

  2. 2

    Scan the receipt

    Photograph a paper receipt, up to five at once, and review the merchant, date, total and items before saving.

  3. 3

    Set limits per category

    Weekly, monthly or yearly budgets warn you before you overspend, based on what you have recorded.

  4. 4

    Keep working offline

    Entries are stored on your phone first and sync to your account when you are back online.

Built for daily life

Log it in seconds

Add a transaction with a category, amount, and note. Income or expense — Lumy keeps the record straight. Search, filter by date, or browse by family member.

Works with or without a connection

Lumy stores your data locally on device. Log transactions anywhere — everything syncs to the cloud when you're back online.

Track in 44 currencies

Select from a wide range of currencies. Amounts convert automatically so your totals always make sense.

Is this the right setup for you?

A good fit if

  • You do not want to share bank credentials with any app.
  • Your bank is not supported by the usual aggregators, or you use several banks and currencies.
  • A good part of your spending is cash.

Probably not for you if

  • You want your balances and card transactions imported without lifting a finger.
  • You will not record spending as it happens or scan receipts afterwards.

How it compares with the usual alternatives

Bank-connected apps

Automatic imports, at the cost of giving ongoing access to your transactions. Categories still need fixing, cash is invisible, and coverage varies by bank and country.

Spreadsheets

Private and free, but entries are made later from memory, which is where most small spending gets lost.

Your bank's own app

Shows what went through that bank's cards. It cannot combine several banks, cash or a partner's spending into one budget.

Questions people ask

Is it safe to link a bank account to a budget app?

Many apps use regulated data aggregators, but you still grant ongoing access to your transaction data. If you would rather not, a manual tracker avoids the question: Lumy never asks for or stores banking credentials.

How long does manual tracking take?

An entry typed or spoken as it happens takes a few seconds. Receipt scanning covers bigger shops; reviewing the scan before saving is the only extra step.

Does it work without an internet connection?

Yes. Lumy stores data on the device first and syncs to your account when you reconnect.

Is the free plan enough?

The free plan covers manual expense tracking, budgets, goals, subscriptions and limited AI chat (10 messages a month). Receipt scanning, unlimited AI, voice logging, multi-currency and family sharing need Pro.

What about cash and different currencies?

Cash is recorded like any other expense. Multi-currency, with 44 currencies converted automatically, is a Pro feature.
