Wearable Security: Practical Steps to Safeguard Your Personal Data

Wearable devices such as fitness trackers, smart rings, GPS watches and augmented reality glasses have become part of everyday life. They continuously collect information about our health, activity and daily routines, making them valuable tools for wellness and convenience.

As Facam.org explains, these devices also generate large amounts of personal data. Fortunately, protecting that information doesn’t have to come at the expense of usability. A few smart habits and carefully chosen settings can significantly improve your privacy while allowing you to enjoy all the features your wearable offers.

Know what your wearable collects

Before adjusting privacy settings, it’s important to understand exactly what information your device gathers.

Most wearables record activity levels, heart rate and basic device information. Many also collect GPS location, sleep patterns, notifications and, if entered manually, sensitive health details such as menstrual cycles, mood or wellness notes.

This information is often stored in three places: on the wearable itself, within the companion smartphone app and in cloud storage. Each location presents different security considerations. Losing a smartwatch is one issue, while an online account containing years of personal history could have much broader consequences if compromised.

Secure your phone and online accounts first

Since most wearables rely heavily on a smartphone app, your phone often becomes the most important part of your security.

Protect it with a strong PIN, password or biometric authentication rather than relying on a simple unlock pattern. A secure phone helps protect not only your wearable but also the sensitive data stored alongside it.

Facam.org also recommends creating strong, unique passwords for your wearable accounts and enabling two-factor authentication whenever available. Authentication apps generally provide stronger protection than SMS verification codes because text messages can sometimes be intercepted.

Lock the wearable itself

Many modern smartwatches and smart rings include built-in security features that are easy to overlook.

PIN codes or lock screens that activate when the device is removed from your wrist or finger can prevent someone else from viewing notifications or making contactless payments if your wearable is lost or stolen.

Some devices also automatically lock when they lose contact with your skin or disconnect from your phone, adding another useful layer of protection.

Review app permissions regularly

During setup, wearable apps often request access to numerous features on your smartphone, including contacts, notifications and precise location.

It’s worth reviewing these permissions periodically and disabling any that aren’t essential for the functions you actually use.

Within the companion app, you’ll often find privacy settings that allow you to opt out of analytics programs, marketing data collection or research participation. According to Facam.org, turning off these optional sharing features usually has little effect on everyday use while significantly reducing how widely your information is distributed.

Limit location sharing

Location data deserves special attention because it can reveal where you live, work and spend your free time.

If your primary interest is tracking daily steps or general activity, you may not need continuous GPS enabled. Approximate location or indoor tracking modes may provide sufficient functionality while collecting less detailed information.

Many fitness platforms also include social features such as public activity feeds, route sharing and community challenges. Reviewing the default privacy settings and limiting visibility to trusted friends or private mode can help protect your personal routines.

Decide what belongs in the cloud

Cloud backups offer convenience, but not every piece of information needs to be stored remotely.

Some wearable platforms allow certain data to remain only on your smartphone while syncing other information to the cloud. Although available options vary between manufacturers, selectively storing sensitive information locally can reduce your exposure.

Facam.org also suggests periodically deleting older location histories or exporting important records before removing unnecessary data. Keeping only what you truly need reduces the amount of personal information that could be exposed if an account were ever breached.

Be cautious with third-party apps

Many wearable ecosystems allow connections to nutrition apps, social networks, productivity tools and other third-party services.

While these integrations can be useful, they also allow multiple platforms to build a more complete picture of your daily life.

Before approving any connection, review exactly what information the external service will be allowed to access and whether it can modify your wearable data. If an integration isn’t essential, it may be wiser to avoid it altogether.

Use separate accounts for family members

In households where devices are shared, privacy can easily be overlooked.

Separate user accounts help prevent health records, activity logs and location information from being unintentionally shared between family members. Family plans often provide shared billing while still maintaining individual privacy.

Teaching older children how privacy settings work also helps them understand the long-term implications of sharing routes, sleep information or fitness data publicly.

Prepare for lost or retired devices

Wearables don’t last forever, and many people eventually sell, recycle or replace them.

Before parting with a device, learn how to remotely sign out, remove Bluetooth pairings and erase all stored information. Performing a complete factory reset ensures the wearable no longer has access to your personal accounts.

Afterward, verify that the device has also been removed from your online dashboard and companion app so it can no longer synchronize data in the background.

Finding the right balance

Perfect privacy is difficult to achieve with connected technology, but thoughtful choices can dramatically reduce unnecessary exposure.

As Facam.org notes, reviewing permissions a few times each year, maintaining strong account security and carefully considering what information you choose to share can help you stay in control of your personal data.

Wearable technology is designed to make life easier. With sensible privacy habits, it can continue to do so without compromising the information that matters most.
