I Built a Free, Private App for Muslims — No Ads, No Tracking, No Compromise

InfaqKu: A gift from the Muslim community, to the Muslim community.


"Who is it that would loan Allah a goodly loan so He may multiply it for him many times over?"
— QS. Al-Baqarah: 245

Every time I sat down to record my sadaqah, infaq, or zakat, I ended up staring at a notes app — scribbling amounts between grocery lists and meeting reminders. There had to be a better way. A private way. A way that felt worthy of the act itself.

So I built one. And today, I'm releasing it — completely free, forever — to every Muslim who has ever felt the same.

Its name is InfaqKu. In Indonesian, "ku" means "mine." But really, this app belongs to all of us.


What Is InfaqKu?

InfaqKu is a personal Zakat and Infaq management app for Android, designed for Muslims everywhere. It supports both English and Bahasa Indonesia, works in every country, and is built around a single promise: your ibadah stays private, between you and Allah.

  • ✅ 100% Offline
  • ✅ Zero Ads
  • ✅ No Data Collection — ever
  • ✅ Free Forever
  • ✅ Open Source
  • ✅ Biometric Lock (PIN, Pattern, Fingerprint, Face)

That's not marketing copy — it's the architecture. No analytics SDK, no crash reporting cloud, no ad network. The app literally cannot transmit your data because it never connects to any server for your records.


Three Pillars of the App

🌿 Journey — Your Giving, Visualized

The home screen greets you with a living summary: your total giving this week, this month, this year, and all time. But the feature I love most is the Inspirational Tree — a visual metaphor for your spiritual growth, with 12 unique tree illustrations that change with the seasons or your mood. Small detail. Big feeling.

📋 Records — Your Amanah, Organized

Log every act of giving in seconds. Choose from Zakat, Infaq, or Sadaqah. Add an amount, a note, a date. Filter by category or time range. Edit or delete anytime. Your entire history of generosity, searchable and yours alone.

🌙 Reflections — Daily Nourishment

Every day, a verse or hadith about giving waits for you. The app carries 39 Quranic verses, 20 authenticated hadith, and 10 motivational reflections — all about charity, generosity, and the rewards that multiply beyond what we can see. Share one with your family. Start a conversation that matters.


The Zakat Calculator — All Four Types

Calculating zakat shouldn't require a spreadsheet or a trip to the masjid office. InfaqKu includes precise, fiqh-grounded calculators for every main type:

💰 Zakat Maal (Wealth)
Covers gold, silver, cash, and savings. Nisab: 85g gold. Rate: 2.5% after one lunar year (haul).

🌙 Zakat Fitr
Per-person fitrah before Eid. Enter your household size and the local price of rice — the app does the rest.

🌾 Agricultural Zakat
10% for rain-fed crops, 5% for manually irrigated. Nisab: 900 liters of produce. Calculated at harvest time.

🏪 Business Zakat
Total assets minus debts. Nisab: equivalent to 85g gold. Rate: 2.5% after one haul.

Each calculator includes a full info panel explaining the underlying fiqh principles — not just numbers, but understanding.


Privacy Is Not a Feature. It's a Commitment.

I have seen Islamic apps that serve ads alongside Quranic verses. Apps that track your "engagement" with worship content. Apps that monetize the very data of your spiritual life.

InfaqKu is a refusal.

Your records of giving are between you and Allah. They should not pass through anyone else's servers — not mine, not Google's, not any analytics company's.

The app uses your INTERNET permission only because Flutter requires it at the framework level. No data leaves your device for InfaqKu's purposes. Your biometric data is managed entirely by your device's own secure hardware — we never see it.

You can back up your data to an encrypted ZIP on your own device or private cloud. Restore it. Delete everything with one tap. Your data, your control, always.

Here's what we collect: nothing.

What We Don't Collect Status
Personal information ❌ Never
Financial data ❌ Never
Location ❌ Never
Usage analytics ❌ Never
Third-party services ❌ None

This Is Bigger Than One App

InfaqKu is part of a larger mission at FlagoDNA — a small studio ranked Top 4 Startup in Indonesia by F6S, that has quietly built 15+ apps serving 60,000+ downloads and 7,500+ active users. Apps like HadisKu (complete hadith from 14 Imams), FastiQuran (beautiful offline Quran reader), AmalanKu (daily deeds tracker), and more.

Our philosophy is summed up in four Javanese words:

Mlampah ing tresno — Walk in love.

Technology shapes behavior. Every notification, every UI pattern, every algorithm nudges you somewhere. We want Muslim technology to nudge toward taqwa, toward generosity, toward presence — not toward endless scrolling.

InfaqKu is a small act in that larger vision. A tool that quietly honors the sacredness of giving.


Who Is This For?

InfaqKu was built for:

  • The Muslim who wants to track zakat obligations accurately without sharing financial data with an app company
  • The parent who wants to teach children about sadaqah through a simple, visual log of family giving
  • The professional who calculates business zakat annually and needs a reliable, fiqh-grounded tool
  • Anyone who simply wants to remember, at year's end, how much they gave — and feel gratitude for the ability to give at all

A Message to the Community

I am not a large company. I am a developer who built something because I needed it — and because I believe the Muslim community deserves tools built with the same care and intention as the acts of worship they support.

InfaqKu costs you nothing. If it gives you value, the greatest return you can offer is simple: share it. Tell a friend. Post it in your family group. Mention it after Jumu'ah. Every Muslim who tracks their giving more consistently is a ripple of good in the world.

If you find a bug, I want to know. If you have a feature idea, I want to hear it. The source is on GitHub. The conversation is open.

This is not just a tool. It is a gift — from one Muslim, to all Muslims.
