How to get a copy of your health data.
Health data has a habit of living somewhere you do not control. Accounts get migrated, apps get retired, terms get rewritten. A copy you hold yourself is the simplest protection against all of that, and taking one is a short job.
Nothing here needs Me. These are steps on your own iPhone.
Start by seeing what is actually there
Before you export anything, it is worth knowing what your phone already holds. Open the Health app and tap the icon at the bottom right to open the health categories. Tap a category, then below Options tap Data Sources & Access. That screen lists the apps and devices allowed to share that kind of data.
It answers a question most people have never thought to ask: which of your devices is actually writing into Health, and which is keeping its data on its own side. Not every device writes everything. Some write a full picture, some write selectively, and you usually find out at the moment you needed the data.
Take the export
Health can hand you everything it holds, in one file.
- Open the Health app.
- Tap Summary, then tap your picture or initials at the top right.
- Tap Export All Health Data, then choose how you want to share it.
What you get is XML, a common format for moving data between apps. It is not designed to be pleasant reading. It is designed to be a complete, portable record, which is the part that matters.
Ask the service for its own copy as well
An export from Health covers what reached Health. It will not include anything a service worked out and kept to itself: proprietary scores, processed metrics, or history from before you connected the device.
For those, look in the service's own account settings for a data export or download option. Many countries also give people a right to request a copy of the personal data a company holds about them. Where that applies to you, the request usually goes through the company's privacy contact or its support channel.
Keep it somewhere you will still have it
An export is only worth taking if it survives. Put it somewhere you control and will still have access to in a year, then repeat it occasionally. An old copy is better than none. A recent one is better again.
