File sharing between devices can be convenient, especially for families and friends who want to easily send images, videos, documents, and more. However, features like Apple’s AirDrop, Android’s Nearby Share, and Chrome OS’s Self Share can pose privacy risks if not properly managed.
These tools allow people to send files to nearby devices without needing to exchange contact details, which can sometimes lead to unwanted or inappropriate content being shared. Here’s what parents need to know to keep their children safe.

What Is AirDrop (and Nearby Share or Self Share)?
AirDrop, Nearby Share, and Self Share allow users to send files like photos, videos, and documents to other nearby devices using Bluetooth, Wi-Fi, or Near Field Communication (NFC). These features are often used for quick file transfers without the need to send emails or texts.
However, these tools have risks if they are left open for anyone nearby to use. Cyber flashing—the unsolicited sending of inappropriate images—is one growing concern. In schools, students can use these features to share harmful or bullying content with classmates.
Key Risks of AirDrop and Nearby File Sharing

While file-sharing tools are convenient, they can pose several risks if left open:
- Unwanted Content: Strangers or classmates could send inappropriate images, videos, or harmful content to your child’s device.
- Cyber Flashing: In some cases, unsolicited images may be inappropriate or even explicit, exposing children to graphic content.
- Malicious Files: Sharing can also involve transferring malicious files that may compromise the security of your child’s device.
- Distraction: During school hours, students may receive files that disrupt their learning or encourage off-task behavior.
Dangers of AirDrop in the news:

“The primary concern is the security and privacy of their children. The ease with which contact details can be exchanged merely through proximity increases the risk of this sensitive information falling into the wrong hands.” Fox News

How to Turn Off or Control File Sharing Features
Apple AirDrop (iPhones, iPads)
You can adjust AirDrop settings to limit who can send files to your child’s device.
- Steps:
- Open Settings > General > AirDrop.
- Choose from:
- Receiving Off: Prevents anyone from sending files.
- Contacts Only: Only contacts can send files.
- Everyone: Anyone nearby can send files (not recommended).
To further control AirDrop, you can disable it entirely via Screen Time parental controls:
- Go to Settings > Family.
- Tap your child’s name, then select Screen Time > Content & Privacy Restrictions.
- Under Allowed Apps, turn off AirDrop.
Android Nearby Share
For Android devices, Nearby Share can be turned off to prevent unwanted sharing.
- Steps:
- Open Settings > Google > Devices & sharing > Nearby Share.
- Toggle Use Nearby Share off.
Chrome OS Nearby Share (or Self Share)
Chromebooks also allow file sharing through Nearby Share or Self Share. It’s important to disable these settings on school-provided devices to prevent unwanted sharing during school hours.
- Steps:
- Click on the time in the bottom-right corner, then select Settings.
- Tap Connected Devices and turn off Nearby Share.
How to know if Airdrop is switched on
For iPhones or iPads:
- Swipe down from the top right corner of your screen (on iPhone X and later models) or swipe up (on older models) to open the Control Center.
- Look for the AirDrop icon (it looks like a series of concentric circles).
- Press and hold the network box that shows Airplane Mode, Wi-Fi, and Bluetooth settings.
- You’ll see the AirDrop icon below. If it’s switched on, it will display either “Contacts Only” or “Everyone.”
- If you see “Receiving Off,” AirDrop is switched off.
Alternatively:
- Go to Settings > General > AirDrop.
- You can check if AirDrop is set to Receiving Off, Contacts Only, or Everyone.
For Mac:
- Open Finder and select AirDrop from the sidebar.
- In the AirDrop window, check the setting at the bottom. It will indicate whether it’s set to allow file sharing from Contacts Only, Everyone, or if AirDrop is Off.
How to Respond if Your Child Receives an Unwanted File
If your child receives an unexpected file via AirDrop or Nearby Share, it’s important to take immediate action:
- Decline or Cancel: Teach your child to immediately decline or cancel any incoming files from unknown sources.
- Turn Off File Sharing: Disable file-sharing features to prevent further attempts.
- Report the Incident: Encourage your child to report any inappropriate or suspicious files to a trusted adult or teacher.
Why This Matters
File-sharing features can be useful, but they can also lead to situations where children receive inappropriate or harmful content. Unwanted files, like those shared through cyber flashing, can cause distress and may have legal consequences for the sender. By adjusting settings and talking to your child about how to handle unwanted content, you can help protect them from these risks.
Tips for Parents
- Check Default Settings: Make sure file sharing is turned off or limited on all devices your child uses.
- Educate Your Child: Have conversations about the risks of file sharing and what to do if they receive an unwanted file.
- Use Parental Controls: For younger children, use parental controls like Screen Time to limit who can send files to their devices.
- Monitor Devices Regularly: Take time to review your child’s device settings to ensure file sharing remains restricted to trusted contacts.
- Talk to your child about cyberflashing
Conclusion
While AirDrop and similar file-sharing tools can be helpful, they come with potential risks, especially for children. Taking a few minutes to adjust privacy settings and teaching your child how to handle unwanted files can go a long way in keeping them safe. Be proactive about managing these features and staying involved in your child’s digital life.
