Privacy and data

In short

  • Find out today whether your records live on your phone or in the cloud; that decides what happens if it's lost.
  • Screen lock, Find My and up-to-date software should be ready before your phone ever goes missing.
  • Once you notice it's gone, mark the phone as lost from another device and tell your carrier.
  • Records stored only on the phone disappear with it unless you back them up regularly.
  • An app lock and notification privacy add a second layer if your phone ends up in someone else's hands.

Your medication plans, your period dates, your doctor's notes… If it's all on your phone, leaving it in a café or having it slip out of your bag doesn't feel like losing just any device. In this post we walk you through, in a simple order, where your health records actually live, what you can do before your phone goes missing, and the steps to take in the first few hours if it does.

Where do your health records actually live?

What happens when your phone is lost depends largely on where your records are stored. Some apps send data to their own servers or to the cloud; others keep it only on the phone. With the first kind, you can reach your records from another device even if the phone is gone, but your data also exists outside your device. With the second, your data stays with you alone; in return, backing it up is your job.

To know which applies to you, one look at the privacy and backup settings of the app you use is enough. You'll find a step-by-step guide to reading those settings in our post on where your health data is stored.

There's no good or bad option here; what matters is knowing which one you use. For every app you keep records in, ask yourself two questions: Do these records exist somewhere without my phone? If so, who can access them? The answers show which of the steps below matter most for you.

What you can do before your phone goes missing

The preparations that help most are the ones you make while the phone is still in your pocket. The US Federal Trade Commission (FTC) highlights a few basic measures for your phone and the data on it. Here's how to think about them for your health records:

  • Screen lock: Let your phone lock when you're not using it, and use a passcode of at least 6 digits. Face ID or Touch ID makes this lock effortless in everyday use.
  • Find My: Make sure Find My is turned on on your iPhone. You'll need it to locate, lock or erase the phone if it's lost.
  • Updates: Try not to put off iOS and app updates; they often include fixes that close known gaps.
  • Regular backups: If your records live only on your phone, back them up at regular intervals and keep the backup somewhere other than the phone.
  • App lock: If your health app has its own lock, turn it on. Even if your phone ends up unlocked in someone else's hands, your records stay behind a second door.

Notifications on your lock screen are another detail not to overlook. If medication names or check-up details appear there, that information can be read even while the phone is locked. We explain how to change this in Hiding medication names in notifications.

What should you do in the first hours after losing your phone?

Feeling panicked when you realize your phone is gone is completely natural. The order below is based on the steps Apple recommends for a lost or stolen iPhone; we've kept it short so you can follow it even in the moment:

  1. Check its location from another device. In the Find My app on another Apple device, or at icloud.com/find, you can see your phone on a map and play a sound if it's nearby.
  2. Use Mark As Lost. This locks your phone with your passcode and suspends your Apple Pay cards. If you like, you can show contact details on the screen so whoever finds it can reach you.
  3. Tell your carrier and, if needed, the police. If your phone was stolen or it's becoming unlikely to turn up, report your line to your carrier. Filing an official report of the loss or theft makes the next steps easier.
  4. Decide whether to erase it. If you think you won't get the phone back, you can erase it remotely through Find My. Apple reminds you not to remove the device from Find My after erasing it; if you do, Activation Lock is turned off too, and someone else can use the phone more easily.
  5. Review your account. Check your Apple Account settings and change your password if needed.

One more warning: Apple says it will never contact you to tell you your phone has been found. Messages or calls saying “Your phone has been found” may be scams trying to get hold of your account details.

If your phone turns up later, take a few minutes anyway. If you think someone might have seen your passcode, change it, and take a quick look at your app and account settings. Noting down what you did and what helped makes it easier to stay calm next time.

If you have a backup, do your records come back?

This is the question people ask most when a phone goes missing. The answer is simple: if your records also exist somewhere outside your phone, they come back; if not, they go with the phone. With apps that send records to the cloud, signing in on the new device is often enough. With apps that store data only on the device, you need a backup file.

That's why backing up once and forgetting about it isn't enough. The more recent your last backup, the less you lose. Keep the backup file not on the phone itself but on your computer or in another storage location you choose; otherwise it's lost along with the phone.

Once you have a backup, give restoring a thought too: knowing where the file is and how to move it to a new phone means knowing where to find what you need when it counts. Because the backup file contains health information too, store it with care; don't put it in shared folders or places others can access.

Your records in Oveluni and a lost phone

In Oveluni, your records are stored on this iPhone; there's no automatic cloud backup and no analytics tracking. That means your data stays on your device, and it also means the backup is in your hands. With Create backup you can make a copy of your records, then on a new iPhone choose restore from file, or use the move to a new iPhone option. For the full step-by-step process, see our guide to moving your Oveluni records to a new iPhone.

In case your phone ends up unlocked in someone else's hands, you can set up an app lock with Face ID, Touch ID or a passcode. The “Hide medication names” and “Hide check-up and pregnancy details” options in Notification Privacy settings let you decide what shows on your lock screen. You can browse all of the app's features on the Features page. Oveluni is coming soon to the App Store.
