Straight answers
Your group business stays group business.
The useful parts of a shared ledger, without turning your personal life into a product.
Emails stay private
People in a group see participant names, never each other’s email addresses.
No ads. No data sales.
Oumox uses your data to run the service—not to sell it or target you with advertising.
You stay in control
Export your information or delete your account from your profile. Oumox records repayments but never moves your money.
Your group, your thing
Made for the plans people actually make.
“Nobody wants to be the group accountant. That’s the whole point.”
Good questions
Before you start splitting.
Do we all need the app?
No. Oumox works in a browser too, so everyone can join from the device they already have.
Can I choose exactly how an expense is split?
Yes. Split equally, enter exact amounts, or use percentages. You also choose who paid and who participated.
Does Oumox move money?
Not currently. Oumox keeps the math and the record straight; you settle using whichever payment method your group prefers.
Is Oumox free?
Oumox is currently free to use.
Ready when your group is
