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, you might not want all your health information to show up and be tracked for added personal privacy. If you decide 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 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.

  • If you don’t want to erase the data stored in iCloud, go to Settings > your Apple ID > iCloud and toggle off the Health app before you delete any data from your phone.
  • If you want to erase all your health data from your iPhone and iCloud, go to Settings > your Apple ID > iCloud and verify you toggled on the Health app before you delete any data from your phone.

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

Follow these steps to remove all your health data from your iPhone & Apple Watch

  1. On your iPhone, open the Health app (you can go to the Settings app > Health app to delete your health app’s data–see the FAQ section for step-by-step instructions)

    3. After several minutes, once Apple creates that zip file, you can then save it elsewhere–this file is often huge (as in hundreds of MBs and possibly GBs)
  5. Under Privacy, tap Devices (called Sources in older iOS versions) privacy settings in Health app iPhone
  6. Under the list of devices, you see all the sources for your health data. Each time you pair/unpair a watch, it shows up as a new source, even if it’s the same watch Remove data from a device inside the iPhone Health app

  8. Tap Delete from the confirmation message to erase all data from this device
  9. Repeat for all listed devices until you erase all your health data from your devices

  1. Go back to the Health app’s Privacy section and tap Apps app privacy settings for Apple Health
  2. Tap on an app that reads and writes data to the Health app Apple Health app and apps that read and write data to the Health app

When you delete all your health data from your iPhone, it resets your awards and badges on any paired Apple Watch. If you want to keep your awards and badges, do not clear out all of your iPhone’s Health data–instead, choose a selective approach.

How to delete some of your health data from your iPhone & Apple Watch

If you don’t want to remove all your health data and want to selectively choose which data remains and which data goes, follow the steps that cover what you want to do.

Remove health data by app

Since you always give permission for an app to connect to your iPhone’s Health app, you can easily remove that permission and delete that app’s data from the health app.

  1. Open the Health app
  2. Tap your profile picture or icon
  3. Scroll down to the Privacy section Health app privacy settings for apps
  4. Tap Apps

  8. Choose Delete All Data from “app nameApple Health app Delete all app data from a connected app
  9. Confirm you want to delete that app’s data.

This permanently removes the app’s data from your Health app and disconnects the app, and deletes all its collected data from your iPhone’s Health app.

  1. Open the Health app
  2. Choose the Browse tab
  3. Under Health Categories, select the type of data you wish to remove from things like Activity, Body Measurements, Hearing, Heart, and so forth
    1. If you don’t see the category you’re looking for, choose Other Data Browse options in iPhone Health app
  4. Tap on a specific instance and scroll down the summary information to the Options section, and tap Show All Data Remove health data by category
  5. To remove data, swipe on a record to delete a specific record or select the Edit button and tap the red minus symbol

    2. To delete all instances, choose Delete All Delete an instance of data in the Health app

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 it. unpair apple watch from iPhone

You’ll need to set it up as new or restore it 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 adjusting which apps have access.

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

Can I delete or reset just some of my fitness and activity data?

If you see some fitness data that isn’t correct or that was taken while someone else wore your Apple Watch or had your phone, you can indeed delete just that data subset.

  • 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
  • Tap on the activity or data that you do not want your device to collect delete a data point in the Health app on iPhone
  • Scroll down to Options and tap Show All Data
  • Locate the data you wish to remove and either swipe to delete it or tap it to drill down into that entry and then swipe on the data you wish to remove
  • To remove all data, tap Edit and choose the option to Delete All–this action removes all your entries, so only select this option if you want to remove all your data
  • Repeat to remove any additional entries
  • Tap Done when complete
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.

  2. Hello, I am trying to clear out all of the data from my Apple Watch fitness app, so I can start fresh.

    I’ve tried recalibrating, unpairing and repairing my phone, clearing out using the health app- under devices.

    But nothing is working, my old data is still showing. Please help.

    • Hi Megan,

      Sorry to hear about that. It may be that you turned off the Health app in your iCloud settings before you deleted data and then toggled it back on which refreshed that data since it was stored on iCloud.

      Leave the Health app enabled in your iCloud settings and try deleting your old data again from your iPhone. You can delete that data via the Health app or via Settings > Health app > Data Access & Devices. Then choose the app and delete their data and choose your devices and delete all that data.

  3. Under Settings > Privacy, you can select “Health” and then the Health app and “delete all data”. But when I did this, I noticed that nothing got deleted. I also cannot find any reference online about what this actually does. I followed your steps, and it worked, but I’m still curious and wondered if you know: why is that option available under Privacy when it doesn’t seem to do anything (and no one mentions it or explains what it does)? I’m on iOS 15.5.

    • Hi Marc,

      Yes, it does seem counter-intuitive but currently (iOS 15.5) when you choose the option to Delete All Data from Health under your iPhone’s Privacy Settings, it only deletes data recorded by your iPhone and not any third-party apps or connected devices, including the Apple Watch.

      To delete that data, follow my steps from the Health app. Make sure you check your iCloud Health app settings before you begin.

        If you don’t want to erase the data from iCloud, toggle the Health app setting in iCloud off (grayed out.)
        If want to erase the data from iCloud, toggle the Health app setting in iCloud on (green.)

      You can also delete this data from the Settings app.

      Again, check your iCloud Health app settings before you begin.

        If you don’t want to erase the data from iCloud, toggle the Health app setting in iCloud off (grayed out.)
        If want to erase the data from iCloud, toggle the Health app setting in iCloud on (green.)
        Open Settings > Health.
        Scroll to Data and tap Data Access & Devices, then go through each app one by one to delete its data.
        After tapping an app, scroll down and tap Delete All Data from “the app name.” Then confirm you wish to delete that data.
        Repeat for each app.
        Once done with each app, go back to Settings > Health > Data Access & Devices.
        Then scroll down to each listed device and delete its data by selecting it, scrolling all the way down, and tapping Delete All Data from “that device name.”
        Confirm you wish to delete that data.
        Repeat for each listed device.

      If you also store health records on your iPhone, including your Covid vaccine digital certificate, you need to delete that too!

        Open the Health app and choose the Summary tab.
        Tap your profile picture or icon from the top.
        Under the Features category, tap Health Records.
        Choose the provider that you want to remove.
        Tap Remove Account.
        Confirm by tapping Remove Account & Delete Data.
        Repeat for any additional health records providers.

      Hope that helps.

      Amanda
