Can Your Smartwatch Data Help Your Michigan Injury Claim?
After a crash or a fall, you are hurt, you are worried about money, and now you are wondering whether the watch on your wrist matters. It can. The steps, heart rate, sleep, and GPS your Apple Watch or Fitbit quietly records can become real evidence, and it can cut both ways. Used the right way, that data is objective proof that your injury changed how you live, which is a big part of what Michigan law asks you to show in a car accident claim. Used against you, an insurer (often with the help of AI software) can twist a few numbers to claim you are not really hurt. Here is the bottom line: do not delete anything, do not hand your data to an adjuster on your own, and read this before you do either.
What Your Watch Is Actually Recording
Most people have no idea how much their device stores. A modern smartwatch or fitness tracker logs your step count, distance, flights of stairs, active minutes, heart rate, sometimes blood oxygen and sleep stages, and frequently your GPS location and pace. Your phone keeps a lot of the same information. All of it carries a timestamp. That means there is a minute-by-minute record of what your body was doing before your injury and what it has been doing since. In a personal injury claim, that timeline can be powerful, because the central question is not just that you were hurt, it is how the injury changed your daily life.
Can the Insurance Company Get My Smartwatch Data?
Sometimes, yes. Once you file a lawsuit, the other side can request information that is relevant to your claim through the discovery process. Michigan Court Rule 2.302(B) lets parties obtain relevant, non-privileged material, but it also limits requests to what is proportional to the case, so an insurer cannot simply vacuum up years of your private health data on a hunch. If your physical activity is truly in dispute, though, a court may order you to produce the relevant portions. The key word is relevant. A good attorney fights to keep the request narrow and tied to the real issues, instead of letting the defense rummage through everything you have ever tracked.
What you should not do is assume the data is private just because it lives on your wrist. Insurers already pull public information about claimants, the same pattern we describe in our guide to AI social media surveillance in injury claims. Wearable data is the next frontier, and the safest move is to treat it as something that may one day be seen by the other side.
How Your Data Can Help Your Claim
This is the part most injured people miss. Wearable data is often the most objective evidence you have. Insurers love to argue that pain is exaggerated because they cannot see it. Your device can answer back with numbers. If you walked 9,000 steps a day before the crash and 1,200 a day after, that is a hard, time-stamped record of reduced mobility. If your sleep was steady and now your watch shows you waking in pain every night, that supports your account. In a car accident case, Michigan’s injury threshold in MCL 500.3135 asks for three things together: an objectively manifested impairment, of an important body function, that affects your general ability to lead your normal life, as the Supreme Court explained in McCormick v Carrier, 487 Mich 180 (2010). Wearable data speaks most directly to that last part, how your normal life changed, and it can back up the first part too. It does not replace medical proof of the injury itself, so think of your watch as powerful support for your doctor’s findings, not a substitute for them. Used that way, a before-and-after activity record can speak to the threshold more convincingly than testimony alone.
How It Can Hurt You, and Where AI Comes In
The same numbers can be turned against you, and this is where artificial intelligence changes the game. Insurers now use software to ingest large data sets and surface anything that looks inconsistent. If your tracker logged 6,000 steps on one good day, an algorithm can flag it and an adjuster can wave it around as proof you are fine, ignoring that you paid for that day with a week of pain, or that the watch counted steps while you were a passenger in a car. Raw activity numbers have no context, and AI tools are very good at stripping context away. A single high reading, pulled out of a year of low ones, can be made to look damning to a jury if no one explains it. That is why you do not want a machine, or an adjuster, telling your story for you.
Do Not Delete It: The Spoliation Trap
Once you know a claim is coming, deleting your data is one of the worst things you can do. Michigan law imposes a duty to preserve evidence you know or reasonably should know is relevant, even before a lawsuit is filed. In Brenner v Kolk, 226 Mich App 149 (1997), the Court of Appeals confirmed that a party who destroys such evidence can be sanctioned, and a jury can be told to assume the missing evidence would have hurt that party. If you wipe your watch or cancel your account after a crash, the defense can argue you hid something, and a judge may instruct the jury to hold it against you. The right move is the opposite: preserve it, then let your attorney decide what is helpful and how to present it.
Will a Judge Even Let This Data In?
Not automatically. Before any device data reaches a jury, it has to be authenticated, meaning someone has to show it really is your data and that the device produces reliable readings. Michigan Rule of Evidence 901, including 901(b)(9) for evidence produced by a process or system, governs that step. If an expert is needed to interpret the numbers, MRE 702 (amended effective May 1, 2024) requires that the methods be reliable. And even relevant data can be excluded under MRE 403 if it would mislead the jury more than it helps. These rules protect you as much as the insurer, because they give your lawyer the tools to keep cherry-picked, misleading snippets out, the same authentication fights we cover in our guide to AI-generated evidence and authentication.
| Wearable data | How it can help you | How an insurer (or its AI) may twist it |
|---|---|---|
| Daily step count | Shows a clear drop in activity after the injury | Points to one high day to claim you recovered |
| Heart rate and sleep | Supports ongoing pain and disrupted rest | Argues normal readings mean no real injury |
| GPS and location | Confirms where you were and how little you moved | Claims a trip proves you are active and fine |
| Active minutes | Documents reduced exertion over time | Flags any spike as inconsistent with your claim |
What to Do Right Now
Keep your device and your account exactly as they are, and stop changing settings or deleting history. Do not send screenshots or export files to any adjuster, and do not agree to “share” your health data to speed up a claim, because that is rarely in your interest. Write down, while it is fresh, how your activity and sleep changed after the injury, so your own records line up with the device. Then talk to a lawyer before anyone asks for the data formally. Handled correctly, your watch can be one of the strongest, most objective witnesses you have. Handled carelessly, it becomes the insurer’s best argument. The difference is usually who controls the story.
अक्सर पूछे जाने वाले प्रश्न
Can the insurance company force me to hand over my Fitbit or Apple Watch data?
Only if it is relevant to your claim and only through proper discovery once a lawsuit is filed. Michigan Court Rule 2.302(B) allows relevant requests but limits them to what is proportional to the case, so a broad demand for years of private health data can be challenged and narrowed by your attorney.
Will my smartwatch help or hurt my injury case?
It depends on the full picture and who presents it. A before-and-after drop in activity can be strong proof your injury changed your normal life under MCL 500.3135. The danger is out-of-context numbers, which AI review tools are good at surfacing, so the data should be explained by your lawyer, not an adjuster.
Should I delete my fitness data after an accident?
No. Deleting it can be treated as destroying evidence. Under Brenner v Kolk, 226 Mich App 149 (1997), a court can sanction you and even tell the jury to assume the missing data would have hurt your case. Preserve everything and let your attorney decide what to use.
Is my health data automatically allowed as evidence?
No. It must be authenticated as truly yours and reliable under MRE 901, and any expert interpretation must meet MRE 702. A judge can also exclude misleading snippets under MRE 403. These rules give your lawyer room to keep cherry-picked readings out.
The adjuster asked me to share my activity data to speed things up. Should I?
Be very cautious. You are rarely required to volunteer raw data directly to an adjuster, and doing so hands the insurer material it can interpret against you. Talk to a lawyer first so the scope is controlled and the context is preserved.
