Free for churches, forever
Your church, in order.
Who was missing on Sunday? ChurchOS tells you at a glance. Replace Excel spreadsheets and notebooks: people and families, attendance with QR self check-in, offerings and tithes, and your church's finances, all from the phone already in your pocket.
Everything this page describes is available today.
A 45-second walkthrough of ChurchOS, in Spanish.
Sound familiar?
The membership spreadsheet
The congregation list lives in a spreadsheet only one person knows how to open, and nobody is sure which version is the right one.
People and families
AvailableRegister a person in four taps from your phone. Find them even if you type their name without accents. Group members by family. Bring the member list you already have: upload your spreadsheet and ChurchOS turns it into tidy records.
The attendance nobody remembers
Every Sunday someone counts heads, and by Tuesday the number is gone: nobody can say how many came last month, or who was missing.
Attendance
AvailableTake attendance at every service from your phone: by name or by headcount. Members can also check themselves in with a QR code, and you see who was missing at a glance.
The offerings notebook
Tithes and offerings are written by hand in a notebook that can't be searched, totaled or backed up.
Offerings and tithes
AvailableRecord tithes and offerings by fund, in batches that are closed and locked. Generate each member's giving statement as a PDF whenever you need it.
The church's money, out of control
Expenses and transfers between cash boxes are noted separately, if at all, and nobody can say for sure how much the church has today.
Finances
AvailableYour church's monthly cash box: income, expenses, transfers between funds and the real balance, no parallel spreadsheets.
ChurchOS exists so your church never has to go through this again.
Role-based access. Pastor, secretary and treasurer: each one sees exactly what they need, and nothing more. Modules that fit. Turn on only what your church uses. Every module can be switched on or off from settings, at no cost. Configuration that fits. Custom fields, roles for pastor, treasurer and leader, invite people by link, a full export of your data, and an audit log of every change.
What it looks like.




Built for churches like yours.
ChurchOS is designed for evangelical churches of 30 to 200 members, starting in Bolivia.
- For the secretary, who registers and finds every member from their phone.
- For the treasurer, who gives a clear account without fighting spreadsheets.
- For the pastor, who sees the state of the congregation at a glance.
Everything works on the phone first, because that's where the real work gets done.
Available in Spanish and English, with room for several churches on one account.
Your data belongs to your church.
Every church, isolated. Your church's data is separated from every other church's at the database level, and an automated test checks it on every change we make to the system. Nobody from another congregation can see it, not even by mistake.
Yours, not ours. Your congregation's information belongs to your church. We don't sell it, we don't share it and we don't use it for advertising.
No fine print. There are no hidden paid plans or features that get charged later. What you see is what you get.
Every change, under control. Offering batches are closed and frozen; reopening one is a treasury action and is recorded in the audit log. You can export all your data whenever you want, and erase a person's personal data if they ask.
Free, and we mean it.
ChurchOS has no plans, licenses or monthly fees. Any church can use all of it, without paying anything, today and always.
This project is sustained by voluntary donations from people who believe the church deserves good tools.
