Stalker Alerts: Tracker Warnings, Offender Notifications, and Account Alerts

What "Stalker Alert" Can Mean

The phrase covers several different tools.

• Unknown tracker alerts. Notifications on your phone that a small Bluetooth tracker you don't own is traveling with you.
• Offender notifications. Automated messages from the justice system when a person in custody is released, transferred, or has a court date.
• Account security alerts. Emails or texts when someone logs in to your account from a new device or changes a setting.
• Safety apps and alarms. Tools that share your location with trusted people or sound an alarm.
• Your own alert network. Friends, family, and coworkers who know what to watch for and whom to call.

The sections below take them in turn.

Unknown Tracker Alerts on Your Phone

Small Bluetooth trackers are useful for finding keys and luggage, and they can also be hidden in a bag, car, or coat to follow someone. To reduce that risk, many phones and tracker makers now include protections that can warn you when an unfamiliar tracker is moving with you.

• Check your phone's settings for unknown-tracker or item-tracking alerts, and make sure they are turned on, along with Bluetooth and location services as required.
• Know that coverage is limited. Alerts work for trackers designed to work with them, and they may not catch every device or every kind of tracker.
• Learn to scan manually. Some phones let you scan for nearby trackers you can't see.
• Pay attention to odd sounds. Some trackers beep after being separated from their owner for a while.

An alert is information, not proof of stalking. But if it appears more than once, or you find a device you didn't place, take it seriously. Read stalking without words: following and tracking.

What to Do If a Tracker Alert Goes Off

How you respond matters for your safety and for any later case.

1. Stay calm and don't go home if you think someone may be following your location. Go to a public place, such as a police station or busy store.
2. Look for the device. Check bags, pockets, car seats, wheel wells, bumpers, and under the dashboard. If you can, photograph it where you find it before moving it.
3. Don't confront anyone. The person who placed it may not be nearby, or may be.
4. Call the police and tell them you found a tracking device. They can document it, and in some cases collect it as evidence.
5. Keep the device if police advise it, and write down the time, place, and what happened.
6. Update your safety plan. If the stalker could know where you have been, think about where you are going next.

Disabling the device can alert the stalker. If you feel you are in danger, call 911.

Offender Release Notifications

If someone has been arrested or convicted in a stalking case, you can often register to be notified when their custody status changes.

• Ask the prosecutor's victim-witness unit or the arresting agency how to register.
• Use your state's notification system. Most states run an automated service for jail and prison release, transfer, or escape.
• Register a phone number and email you can safely receive messages on, and keep them current.
• Find your state's victim services through the Office for Victims of Crime Help in Your State directory or our State Reporting Guide.

Notifications about court dates matter too. Ask whether you can be told when hearings are scheduled and when a protective order is served.

Account Security Alerts

Many stalkers get in through accounts rather than devices. Alerts can tell you quickly when that happens.

• Turn on login alerts for email, cloud storage, social media, and banking, so you hear about new devices and locations.
• Send alerts to a safe address or number, one the stalker can't read.
• Add multi-factor authentication. The Cybersecurity and Infrastructure Security Agency's Secure Our World pages explain how.
• Review recovery options. Make sure the recovery email and phone number are yours.
• Check connected apps and devices every few months, and remove any you don't recognize.

If you receive a "new login" alert you didn't cause, change your password from a safe device and save a screenshot first.

Safety Apps, Alarms, and Alert Networks

Personal safety tools can help, but choose them thoughtfully.

• Location sharing with a few trusted people can let them know where you are. Be careful: shared location can be misused if the wrong person has access or if the stalker can see the account.
• Check-in features can notify a contact if you don't confirm you are safe by a certain time.
• Personal alarms can attract attention if you feel threatened.
• A code word lets you ask for help without saying so out loud. Agree on one with someone you trust.
• Workplace and school alerts. Ask your employer or school to notify you if someone asks about you or appears at the building.

Build these into your safety plan, and consider whether each one could be turned against you.

When an Alert Turns Out to Be a False Alarm

Not every alert means someone is watching you. Common false alarms include a friend's or family member's tracker traveling with you in a shared car, a lost item that belongs to someone nearby, or an old device you forgot about.

Still, treat the first alert seriously until you can explain it. If you find a harmless explanation, note it in your log. If the alerts keep appearing with no explanation, or you find a device you didn't place, report it. You can also file an internet crime complaint with the FBI's Internet Crime Complaint Center when technology is involved.

A Quick Setup Checklist for Your Alerts

Spend thirty minutes setting these up, and you will have much better early warning.

1. Phone settings. Turn on unknown-tracker alerts, Bluetooth, and any needed location permissions. Ask a friend to test whether your phone can detect a tracker they carry.
2. Account alerts. Enable login and new-device alerts on email, cloud storage, social media, and banking, and send them to a safe address.
3. Multi-factor authentication. Turn it on for every important account, and keep recovery methods current.
4. Offender notification. If a case exists, register through the prosecutor's victim-witness unit or your state's system.
5. Trusted contacts. Choose two or three people, share your code word, and tell them what to do if they get a certain message from you.
6. Printed list. Write down the numbers and steps for each alert on paper and keep it where the stalker can't find it.
7. Review monthly. Test your alerts, remove old devices, and update contacts.

If you suspect your devices are compromised, set these up from a safe device. Read the complete guide to digital safety and build your plan in the Safety Plan tool.

An alert doesn't have to be a crisis. It can be a prompt to check, document, and protect yourself.
