Question 1

Does Lumi require access to my bank account?

Accepted Answer

No. Lumi never asks for bank credentials, card numbers, or financial institution access. All data is stored locally on your device. Apple Pay transactions are imported via iOS Shortcuts — a one-time setup that requires no third-party access.

Question 2

How does Back Tap logging work?

Accepted Answer

Back Tap is a built-in iOS accessibility gesture — double-tap the back of your iPhone to trigger any action. In Lumi, it opens the app directly in expense-recording mode. No unlocking, no searching for the app, no extra taps. You can log an expense in under 3 seconds from any situation.

Question 3

How does Apple Pay auto-import work?

Accepted Answer

Set up a one-time iOS Shortcut that triggers when Apple Pay is used. Every contactless payment automatically creates an expense entry in Lumi with the correct amount, merchant name, and timestamp. No manual input required after setup.

Question 4

How accurate is the AI spending forecast?

Accepted Answer

Lumi calculates your average daily spend rate from the last 3 months (excluding statistical outliers like one-off large purchases), then projects it to month-end. If you have income data entered, it also shows your projected balance. Confidence scores are shown so you always know how reliable the forecast is.

Question 5

Is Lumi available on Android?

Accepted Answer

Currently Lumi is iOS only. Back Tap and Apple Pay integrations are iOS-native features. An Android version is on the roadmap.

Question 6

What currencies does Lumi support?

Accepted Answer

The free plan includes 2 currencies with real-time conversion. Premium includes 150+ currencies with automatic exchange rate updates. Useful for travel, expat life, or managing income in multiple currencies.

Question 7

Is my financial data private and secure?

Accepted Answer

All your data is stored exclusively on your device — Lumi has no servers storing your transactions. There is no account required to use the app. No data is sold or shared with third parties. You can export or delete everything at any time.

Question 8

How does the receipt scanner work?

Accepted Answer

Point your iPhone camera at any paper or digital receipt. Lumi's AI Vision reads the total amount, date, merchant name, and assigns a spending category — even for receipts in foreign languages. The scan takes 2–3 seconds.

Question 9

Is Lumi free to use?

Accepted Answer

Yes. The free plan includes 10 AI receipt scans per month, 2 budgets, Back Tap logging, Apple Pay auto-import, and basic analytics. Lumi Premium ($4.99/month or $39.99/year) unlocks unlimited scans, unlimited budgets, AI forecasting, advanced analytics, and full multi-currency support.

Question 10

What makes Lumi different from YNAB, Copilot, or Monarch?

Accepted Answer

Three things no competitor offers simultaneously: (1) Back Tap instant logging — log without opening the app. (2) Apple Pay auto-import — zero-effort automatic logging. (3) Local-first privacy — no bank login, no cloud, your data never leaves your phone. YNAB, Monarch, and Copilot all require bank account access and store data in the cloud.
