Outdo is a fitness competition app. It reads your Apple Watch Activity rings and compares them with your friends'. This page explains exactly what that means for your data — in particular the part people don't expect, which is how much of it your competitors can see.
The short version. Outdo reads three things from Apple Health: your Move, Exercise and Stand rings, plus the goals you set for them. When you join a competition, every other member of that competition sees your exact numbers. Your health data is never sold, never shared with advertisers, and never used to target advertising at you. You can delete all of it from inside the app, permanently, at any time.
Outdo is developed and operated by Arihant Gupta, an independent developer. For any question about this policy or your data, write to support.outdoapp@gmail.com.
With your permission, and only with your permission, Outdo reads:
Outdo reads daily totals. It does not read workouts, heart rate, sleep, body measurements, clinical records, or any other health data type. Outdo never writes anything to Apple Health, and it cannot change your Apple Watch goals — those are yours to set in the Fitness app.
You can withdraw access at any time in Settings → Privacy & Security → Health → Outdo. Outdo will stop reading new data immediately; anything already synced stays until you delete your account.
Outdo reads the three Activity rings above and nothing else. It does not read your sleep, heart rate, heart-rate variability, workouts, body measurements, menstrual or reproductive health, clinical records, or any other Health category.
Features under consideration for a future Pro tier — such as sleep, recovery and heart-rate variability analysis — would need some of that data. None of it is read today, and none of it leaves your device today. If that ever changes:
Granting a new permission later is entirely your choice, and declining it only turns off the feature that needs it.

My Email. Outdo stores it but does not currently display it, use it, or send mail to it.This is the important part, and it is deliberate. Outdo exists because capped, blurred fitness competition is boring and easy to game. Everyone in a competition you join can see your exact figures: your Move, Exercise and Stand numbers, the goals you were scored against, your points, your daily and best-day totals, your display name, your username, and how many rounds you have played in that group.
That transparency is the product. It is why nobody can quietly set a soft goal and win on paper. If you are not comfortable with a particular group seeing your numbers, do not join that competition — or leave it, which stops sharing your data with it from that moment.
People who are not in a competition with you cannot see your activity at all. Your personal, non-competition activity — what you see on the Home tab — is visible only to you.
Outdo stores data in a PostgreSQL database hosted by Supabase, which processes it solely to provide the app. Push notifications are delivered through Apple's Push Notification service, and sign-in is handled by Apple.
Health data is never written to iCloud, which Apple's Developer Program License Agreement prohibits outright. Apple, Supabase and your own device are the only places your Outdo data exists.
Plainly, and without qualification:
This is not only our choice. Apple's rules for apps that read Apple Health prohibit using that data for advertising, marketing or use-based data mining, and prohibit disclosing it to third parties — and no amount of consent unlocks it.
The only place your health data is shared with other people is inside a competition you chose to join, as described above.
Outdo shows no advertising today. We may add it in a future version — and if we do, the line above does not move: no advert will ever be selected or targeted using your health data, or anything derived from it. Not your rings, not your goals, not your points, streaks, rank or competition history.
In practice that means any advertising would be the same for everyone, or based only on information that has nothing to do with your health.
Before any advertising appears in Outdo, this page will be updated to describe it, and the App Store privacy labels for Outdo will be updated to match. If advertising ever involved tracking you across other companies' apps or websites, iOS would ask your permission first, on its own screen, and you could refuse.
Outdo does no advertising-network tracking today, which is why it does not currently ask for tracking permission.
Your data is kept for as long as your account exists. Delete your account and it goes, as described next.
In the app: Home → your profile icon → Settings → Delete account. It is immediate and permanent — there is no grace period and no restore.
Deleting removes your profile, your username, every day of activity you have ever synced, your notification token, and your place on every leaderboard, including finished rounds you placed in.
One thing survives, on purpose: competitions you created keep running for the people still in them. A competition you started passes to whoever has been a member longest, so that other people's group does not disappear because you left. If you are the only member left, the competition is deleted along with your account.
Deleting your Outdo account does not touch your Apple Health data, which never leaves your iPhone's control and remains exactly as it was.
Outdo is not directed to children under 13, and does not knowingly collect data from them. If you believe a child has created an account, write to the address above and it will be removed.
Depending on where you live, you may have the right to access, correct, export or erase your personal data. Deletion is built into the app. For anything else, write to the address above and it will be handled.
If this policy changes in a way that affects how your data is handled, the date at the top of this page changes and the change will be noted in the app's release notes. Continuing to use Outdo after a change means accepting the updated policy.
