My Pay Market

My Pay Market is the personal expense tracker of the collection. The app lets you record each expense with date/time, amount, currency, payment method, store and category — all editable combos, no rigid lists. "Now" button for quick timestamp, preview of the amount converted to app-currency.

Flagship feature: **receipt OCR**. Take a photo of the receipt (camera or gallery) and Google ML Kit Text Recognition extracts the text on-device — no network, no cloud, receipt never leaves the phone. An internal keyword-based parser identifies amount (TOTAL line), date/time, store and payment method. The keywords used to recognize each field are fully configurable in Settings → "OCR Settings" — you decide what to search for.

History shows the chronological list with detail, edit, delete. Chart aggregates by Daily / Weekly / Monthly / Yearly / Total. Export to CSV or XLSX (with SUM formulas in Excel cells) and standard Android share Intent to send the file via mail / WhatsApp / Drive.

Balances screen computes Balance / Credit / Accumulation of the current period with periodic refill rules: expenses subtract from Accumulation first, then Balance; at period end positive Balance flows into next Accumulation, negative is absorbed; manual refills are CREDIT entries that offset net expenses of the period. All movements visualized as double-entry (DEBIT expense red, CREDIT refill green) with Debit/Credit columns in exports.

Same stack as the other MCC Androids: Kotlin + Jetpack Compose + Material 3 + Room + DataStore + Apache POI for Excel + ML Kit Text Recognition. Native IT/EN multilingual via AppCompat (`AppCompatDelegate.setApplicationLocales`). 4 palettes reused from MyVote (Default Violet / Sunset / Ocean / Forest) + light/dark/system theme.
