Privacy Policy

Your account. An email address, and your name if you choose to give one or if Apple or Google passes it to us when you sign in. That is what identifies your runs as yours.

Health and fitness data. With your permission, the iPhone app reads running workouts from Apple Health: distance, duration, pace, heart rate, cadence, elevation, and the GPS route of the run. If you record a run with our phone or watch app instead, we collect the same things directly.

What you tell us. Anything you enter yourself — year of birth, sex, height, weight, resting heart rate, heart-rate zones, strength numbers, the names and tags you give runs, planned sessions, and life events such as an illness or injury you mark so the graphs can explain a dip.

Photos. Any photo you attach to a run.

Weather. We look up the weather for the time and place of a run so you can see what you were running in, and store the result with the run.

Connected services. If you connect Strava or Garmin, we retrieve your own activities from them on your behalf. If you switch on Strava upload, we send runs our watch app recorded to your Strava account. We never post anything anywhere on your behalf otherwise.

All of it exists to do one thing: show you a run against your own history. Comparing a run to your previous runs at the same effort, estimating your fitness from your own efforts rather than a population table, and noticing when something has changed all require the underlying samples — a summary is not enough.

We do not use your data to build a profile of you for anyone else, to target advertising, or to train models.

Your runs live on your device and are backed up to your account in our database, so they survive a lost phone and so you can sign in on the web and see the same numbers. Photos are held in file storage attached to the same account.

We use Supabase for the database, authentication and file storage; Vercel to host the website; Twilio SendGrid to send email; and Apple for Sign in with Apple and weather. These providers process data on our behalf under their own terms and are not permitted to use it for anything else. Data is stored in the United States.

Health data the app reads through Apple Health gets specific protection, and we commit to it plainly: we do not use it for advertising or any similar service, we do not sell it, and we do not disclose it to third parties except the providers above who store it for us and any service you have explicitly connected.

You control this permission. iOS Settings → Apps → Health → Data Access & Devices → You vs You lets you withdraw it at any time, and the app will stop reading new workouts.

We send account email — confirming your address, resetting a password. If you turn it on, we also send a weekly summary of your running. You can switch the summary off in Settings without affecting account email, which we have to be able to send you.

You can delete your account from inside the iPhone app, in Settings under Account, or on the web in Settings. Deletion is immediate and it is total: your runs, photos, tags, plans, life events, settings, connected-service tokens and the login itself are removed. We do not keep a shadow copy.

Signing out is not deletion — it leaves your account intact so you can sign back in.

For as long as your account exists, because the whole point of the app is the comparison against years of your own history. When you delete your account it goes. Backups held by our providers roll off on their own schedules, within about 30 days.

You vs You is not intended for children under 13, and we do not knowingly collect their data. If you believe a child has created an account, write to us and we will remove it.

Depending on where you live you may have the right to see a copy of your data, correct it, or have it deleted. The app already gives you the last of those directly. For the others, write to us at the address below and we will help.

If we change how data is handled we will update this page and move the date at the top. If a change is significant we will tell you in the app rather than relying on you to check.
