Fifty Fifty
Terms of service
The deal between you and Fifty Fifty. Short, because the app does one thing.
LAST UPDATED August 21, 2026
What Fifty Fifty is
An app for splitting shared expenses between people who trust each other: a trip, a flat, a group of friends. You write down what was spent and the app works out who owes whom.
What it is not
It is not a bank, a wallet or a payment service, and it moves no money at all. When you mark a payment as done, you are writing down something that happened elsewhere — in cash, by transfer, by Bizum. Nothing here charges anyone or transfers anything.
Your account
You get in with a name and nothing else. Linking an email is optional and only serves to recover your groups on another phone; if you link one, the password is yours to look after, and nobody verifies the address, so a typo in it is a typo you will find out about the day you change phones.
What you write is yours
And so is the responsibility for it. Amounts, names and splits are what you and the other members type; the app adds them up faithfully but cannot know whether they are true. If a number is wrong, the person who wrote it is the one who fixes it.
Fair use
Do not use Fifty Fifty to break the law, to harass anyone, or to try to reach groups you were not invited to. An invite code gives access to one group and to nothing else.
Price
The app is free, with no ads and no limits on expenses or groups. If a paid extra ever exists, it will be an optional one-off purchase and everything that is free today will stay free.
Guarantees and limits
The app is provided as it is. It is looked after carefully and there are no known ways to lose your data, but no service can promise it will never fail, and nothing here is a substitute for keeping track of your own money. Liability is limited to what the law allows, and nothing in these terms takes away the rights a consumer has by law.
Ending it
You can leave a group whenever you like and delete your account from Settings, with no explanation and no waiting period. An account may only be closed from this side if it is being used to harm somebody, and you would be told why.
Governing law
Spanish law applies. If you are a consumer, you may also rely on the protection of the law of the country where you live, and bring a claim before its courts.
Changes to these terms
If they change in any way that matters, the app will tell you before it applies. Carrying on using it after that is how you accept the new version; if you would rather not, you can delete your account.
