What Project O2 is, what your stake does, and how we settle up.

What this is

Project O2 runs skill-based fitness races. You put a stake in, you hit a daily target measured from your own health data, and if you finish the race you are paid out of the pot. It is a contest of effort, not a game of chance: your target comes from your own recent history and nothing is drawn, dealt or spun.

You must be 18 or over

Accounts are 18+ everywhere Project O2 operates, and we ask for your date of birth to check it. If we find out an account is under 18, we close it and return any stake that has not already been forfeited.

Your stake is at risk

An entry is a stake, not a subscription and not a deposit you can change your mind about. Miss one daily goal in a race and the stake is forfeited to the pot for the people still in it. That is the whole mechanism, and it is the one thing you should be sure you understand before you tap.

How a payout is worked out

The guarantee is paid first: finishers are paid at least their stake back, at the multiplier the race froze when it was created. What is left of the pot after that is divided among the finishers. O2 is never paid out of a finisher's stake. Each race shows its own frozen figures on the staking sheet before you enter.

Finishing pays you at least the floor. Everything above the floor depends on how many people dropped out, because that is where the surplus comes from. We show a projection before you stake and label it as a projection.

Where our money comes from

Project O2 takes no cut of your stake and no cut of the floor. Our share comes only out of the surplus created by forfeited stakes, on the terms each race froze. If nobody drops out, there is no surplus and we make nothing on that race.

Apple is not involved

Apple is not a sponsor of and is not involved in these contests in any way. Apple has no responsibility for a race, a stake, a payout or a dispute. Your contract for entering a race is with Project O2 alone.

Money in and money out

Deposits and withdrawals run through our payment provider. Withdrawals need a verified email address and, above a lifetime cap, an identity check. Money staked in a live race sits in escrow and is not spendable until that race settles.

Fair play

Health data is screened for the things that make a race unfair: manually entered totals, samples from a source we cannot corroborate, and physically implausible jumps. We may void a day, a race entry or an account for it. If we void your entry for cheating you do not get the stake back.

Closing your account

You can erase your account from inside the app at any time, unless money is still in motion (a live race, a stake in escrow or a withdrawal on its way). We tell you which one it is instead of just refusing. Financial records are kept for accounting, anonymised so they are no longer about you.

If something goes wrong

Write to support@trabalhinho.pt. We answer disputes about a specific day, a specific race or a specific payment with the same records the settlement used.
