What it does

Funds and campaigns
- General, project, zakat, sadaqah and waqf funds.
- Zakat only goes into a zakat fund and waqf only into a waqf fund, and the database enforces it.
- A restricted gift is held as restricted money, never counted as income, and a waqf’s principal is not spent.
- Campaigns with a goal, dates and live progress.
Donors and households
- Each donor is a STAK customer: a person or an organisation, with tax number, address, language and anonymous giving.
- Households for families who give together.
- Consent to be contacted per channel (email, text, WhatsApp, post, phone), with every decision kept.
- A donor sheet with giving by Hijri year and type, and what is promised and not yet received.
Gifts
- General, zakat, sadaqah, zakat al-Fitr, waqf, tithe, offering and membership dues.
- Cash, cheque, bank transfer, card or mobile wallet.
- Each gift posts one balanced journal entry and records the Hijri year and month, with your own moon-sighting correction.
- A gift is never edited: a mistake is reversed, with the reason kept.
Pledges and standing gifts
- Pledges split into 1 to 120 instalments that add up exactly.
- Standing gifts weekly, monthly, quarterly, yearly, or on the last ten days of Ramadan.
- A dues list for the people who record gifts; STAK never charges a donor automatically.
Receipts and annual statements
- Gapless receipt numbers, and a voided number is never reused.
- A receipt freezes its words and figures when it is issued.
- An annual statement per donor, by Gregorian or Hijri year.
- In the donor’s language: Arabic, English, French, Spanish, Turkish, Urdu or Hindi.
Volunteers
- Skills, availability, an emergency contact and a clearance.
- Shifts with places, sign-up and a waiting list, and a shift never holds more people than its places.
- A shift with children or vulnerable people can require a current clearance.
- Check-in by code, and hours per volunteer and per month.
Reports and mosque screens
- Raised, first-time donors, donor retention, income by fund and type, and totals by Hijri year.
- A zakat estimate from the gold price you type in, and the zakat al-Fitr total for a household.
- Screens with prayer times, iqama, Friday prayer and the Hijri date, announcements and a live fundraising bar.

Good questions

Is Giving free?

Giving is a main app, so it can be your one free app, forever. Verified mosques and churches get it free together with the other apps a house of worship needs.

Does STAK hold the donations?

No. STAK records the gifts in your own books, and the money stays in your own bank and payment accounts. STAK never charges a donor automatically.

Can STAK calculate zakat?

It has a zakat estimate: you type in today’s gold price and the wealth; below the nisab it is zero, otherwise 2.5%. It is only an estimate: your scholar decides what counts as wealth.

Do the receipts meet my country’s rules?

Your organisation’s own wording is printed unchanged, and STAK stops a receipt that lacks a fact your country requires (such as the registration number in the United States). Have your adviser confirm the wording for your country.
