How to erase health data from Apple Watch and paired iPhone

how to remove health and fitness data from iPhone and Apple Watch using the Health app

Apple’s Health app records and keeps a lot of your activity and health data, especially when you connect third-party apps to it. And while it’s convenient to access all that data in one place,  for added personal privacy you might not want all your health information to show up and be tracked. If you decide you want to delete some or all of your data from your iPhone or your Apple Watch, this article outlines just how to do that!

There are other reasons to remove health data, from cleaning out storage hogs, removing old and no longer needed health information, or getting rid of someone else’s data that was stored on your device. And the good news is that you can remove all or just some of your health data and you can pick and choose which third-party app data you want to delete too–you have choices!

How to delete all health data from your iPhone & Apple Watch

If you use iCloud, Apple automatically stores your Health data in iCloud. When you erase your health data from your iPhone, it also gets removed from your iCloud account.

To stop storing your Health data in iCloud, go to Settings > your Apple ID > iCloud and toggle off the Health app.

Health data is also stored when you encrypt your backups using Finder or iTunes. Unencrypted backups do not contain your health information.

Remove your activity history from your Apple Watch

The Apple Health app consolidates health data from your iPhone, third-party apps, and syncs information directly from your Apple Watch.

While Apple stores all of your health and activity history on your paired iPhone, your Apple Watch does retain your most recent data. This data includes things like daily tracking of your Activity.

The most comprehensive way to remove any fitness, activity, or other health data from your Apple Watch is to unpair your watch from your iPhone and then re-repair. unpair apple watch from iPhone

You’ll need to set it up as new or restore from an unencrypted iPhone backup via Finder or iTunes (iCloud always creates an encrypted backup.)

Change which apps can read and write Health data using your Apple Watch

Rather than unpair or reset your calibration, you may want to remove app access to your Apple Watch instead.

Manage apps on your Apple Watch by going to Settings > Health > Apps and adjust which apps have access.

FAQs FAQ frequently asked questions

How do I delete an old Apple Watch from my iPhone’s Health app that I no longer have?

One thing you’ll likely notice when you review the list of connected devices inside the Apple Health app on your iPhone is that there are a lot of entries for the Apple Watch.

There is currently no way to delete an Apple Watch entry from the Health app and keep that watch’s health data

Each time you unpair your Apple Watch, the Health app creates another device entry. And unfortunately, even when you restore your watch from a backup, the Health app does not consolidate that data into a single Apple Watch entry.

So if you delete one of your older Apple Watch listings under the Health app’s devices, you lose that data.

If you are okay with that, go to your iPhone’s Health app and tap your profile picture or icon. Under Privacy, choose Devices (or Sources on older iOS versions) and tap each entry to see if you want to remove that data or not. delete a data source from the Health app on iPhone

  • Open the Health app on your iPhone
  • Go to the Browse tab 
  • Choose the category for the activity or health data you wish to remove

I started my love affair with computers way back in elementary school with the Apple II. Since then, I've worked with technology in my career as a media educator and videomaker. I have an MFA in media making from Temple University, where I also taught undergrads as an adjunct faculty member. So I know a thing or two about teaching others and creating how-to guides! After a cancer diagnosis, I turned to mobile technology like my Apple Watch to help me monitor my health throughout my chemotherapy treatment and later, to regain my wellness once in remission. I love sharing how to understand and use mobile tech, like smartwatches and phones, as a tool for empowerment to live our best and healthiest lives!


  1. Very helpful.
    A question: If I delete an old Apple Watch entry from the Health app I will lose that watch’s health data. But does that mean my step counts etc for last year will change and it will look like I did not do any workouts ?

    • Hi Jonathan,

      When you delete health data from the Health app, you do lose all references to that particular data, including activity data like steps.

      So, yes your year’s step count would be impacted if you deleted an old Apple Watch entry.
