Terms of Service

Project O2 · Version 2026-09-04 · Governed by Portuguese law
Read this part if you read nothing else. Project O2 involves real money. You stake it, and if you miss a day you lose it to the people who did not. There is no house edge and no rake, but there is real loss. It is for adults, it is a contest of personal effort rather than chance, and you should not stake money you cannot afford to lose.

1. Who can use it

2. What Project O2 is, and what it is not

Project O2 runs contests of skill and personal effort. Your target is derived from your own 30-day activity baseline, so you compete against your own established habits rather than against other people's fitness or against chance. Meeting the target is within your control.

Project O2 is not a betting service, a casino, a lottery, or a game of chance. No outcome is randomised. We do not accept wagers on events outside your control.

O2 is the sponsor and administrator of every contest. Contests are run by us, not by other users, even when a user has set one up. See the Official Rules.

3. How the money works

Your stake

When you enter a contest you stake a fixed entry amount. It moves from your wallet into escrow for that contest. It is not ours and it is not spendable by us; it is held for the contest.

If you finish

You get your entire stake back first. That is the floor, and it is paid before anything else. On top of it you receive a share of the surplus created by people who did not finish.

If you miss a day

You forfeit your stake. That is the mechanic, and it is the whole point: it is what makes the money you can win real. The forfeited amount goes to the people who finished, and to O2 as its fee.

What O2 takes

We take a share of forfeitures only, on a sliding scale, and we never take anything from the stake of somebody who finished. If nobody drops out, we earn nothing from that contest. Our incentive is deliberately aligned with you succeeding, and the exact percentages are shown in the app before you stake and are frozen for the contest at that moment.

Deposits and withdrawals

Credits

We sometimes give promotional credits, for example after your first missed race. Credits are euros of ours offered toward an entry. They cannot be bought, cannot be withdrawn, cannot be transferred, and expire 30 days after they are granted. If you close your account, unspent credits end with it. Real money and credits never mix: cash in a contest is returned as cash, and credit as credit.

4. Health data and your device

Your results are judged from daily totals your phone reports, which you approve. If your phone stops reporting, or you revoke the permission, or the data arrives late, your day may be judged as missed, and that is a real risk of a real-money contest that depends on a sensor. Keep the permission on and the app installed for the length of a race. See the Privacy Notice for what we do with the data.

5. Fair play

We check for fabricated activity. Attempting to feed the app data your body did not produce, whether by a treadmill-mounted phone, a shaking device, a simulator, or a modified app, is fraud against the other people in your contest, whose money is at stake. We may withhold a payout while we examine a flagged result, and we may close an account and refund the affected contest.

An automated system flags results; a person decides. No account is closed and no payout is withheld permanently by software alone.

6. Subscriptions

Premium is an optional auto-renewing subscription billed through Apple. Payment is charged to your Apple ID at confirmation. It renews automatically unless cancelled at least 24 hours before the period ends. Manage or cancel in your Apple ID settings; deleting the app does not cancel it. Unused time in a period is not refundable when you cancel, which is Apple's rule rather than ours.

7. When we may suspend or close an account

If we close your account, money that is genuinely yours is returned to you. We do not keep balances as a penalty.

8. Beta software

Project O2 is currently in testing. Features may change, data may be reset with notice, and the service may be unavailable. If we reset a testing environment we return any real money first.

9. Liability

We provide the service with reasonable skill and care, but not on a promise of uninterrupted availability. We are not liable for losses caused by your device failing to record activity, by you losing access to your account, or by circumstances outside our reasonable control. Nothing here excludes liability that cannot lawfully be excluded, including for death or personal injury caused by negligence, for fraud, or for your statutory rights as a consumer under Portuguese and EU law.

10. Health and responsible play

Project O2 encourages daily activity. It is not medical advice, and it is not designed for anyone whose health makes daily exertion unwise. Talk to a doctor before starting if you have any doubt. Do not stake money you cannot afford to lose, and do not chase a lost stake with a larger one. If you feel your use is becoming compulsive, close your account; the door is always open and your balance leaves with you.

11. Disputes and law

These terms are governed by Portuguese law, and the courts of Portugal have jurisdiction. As an EU consumer you keep the protections of your country of residence and may use the EU's Online Dispute Resolution platform. Contact us first at support@theprojecto2.com; most things are a misunderstanding we can fix.

12. Changes

The version and date are at the top. The app records which version you accepted. Material changes to the money rules will be put to you for acceptance rather than applied silently.
