집고정 (매달 고정지출 관리)

Jipgojeong is an app that visualizes the money automatically deducted every month in advance.

It focuses on pre-visualization rather than post-hoc accounting — instead of asking "How much did I spend last month?", it focuses on knowing "This much goes out every month" beforehand.

⸻ What does it show?

• This month's total household expenses and usage rate relative to monthly income

• 4-category breakdown (Mandatory · Contract · Subscription · Variable)

• Payment rhythm calendar — Use a heatmap to see which days money tends to be concentrated

• Estimated cumulative amount over 10 years — How much it will cost if the current flow remains unchanged

• Sparkline of fixed expense trends over the past 6 months

• D-day notifications for contract renewals next month

⸻ 4-category system

It groups each item into four categories to create a hierarchy.

• Mandatory — Rent · Maintenance Fees · Insurance

• Contract — Telecom · Internet · Water Purifier Rental

• Subscription — Netflix · YouTube Premium

• Variable — Electricity · Gas · Water · Postpaid Transportation

Tap a category row to expand the items within it, allowing you to edit each item directly.

⸻ Automatic Detection from Card & Bank Notifications

Reads payment notifications sent by credit card and bank apps to identify potential new fixed expenses.

• Not saved immediately upon detection; confirm on the detection screen to add or ignore.

• Notification access is used solely for payment detection and does not leave the system.

• Automatic detection can be turned off at any time in Settings.

⸻ Data is stored only on the device.

• All fixed expenses, payment history, and settings are stored only in the user's device's local DB (Room).

• Data is not uploaded to a server.

• Anonymous crash reporting (Firebase Crashlytics) is the only exception — can be denied in Settings.

• Data can be exported as a file at any time via CSV.

⸻ What this app does not do.

• No mandatory monthly income input — Totals and 10-year cumulative figures can be viewed without entering them.

• No promotional pushes — Notifications are available for Updating, Automatic Detection, and Monthly Summary; each can be turned off individually.

⸻ 3 types of widgets.

You can view the totals that automatically update daily via a home screen widget.

Long press on the launcher → Widgets → Search for 'Home Pin'.
