Cellphone spy software secretly collects information from a phone or monitors its activity. When someone uses it to monitor another person without their knowledge, it is commonly called stalkerware. The term spyware is broader and also covers covert surveillance tools used by governments and criminals.
What cellphone spy software can do
Its capabilities depend on the app and the access it has. It may collect location data, calls, texts, email, photos, videos, or browsing information. Some tools may access microphone functions or record conversations; those capabilities should not be assumed of every app.
A 2023 technical study by Enze Liu and colleagues analyzed 14 distinct Android consumer spyware apps. That sample describes the apps examined, not all spy software, current prevalence, or every phone platform. Read the study.

Stalkerware versus disclosed monitoring
The defining concern with stalkerware is covert monitoring: the person being watched does not know it is happening. Some products are marketed for parental or employee monitoring, but a product label alone does not establish that a particular use is transparent, authorized, or appropriate. The Federal Trade Commission’s Retina-X case involved apps marketed for monitoring children and employees that could also be used to track someone without their knowledge. FTC case information.

How to tell whether a phone may be monitored
Possible warning signs include unexpectedly high data use, battery drain, overheating, unexplained changes in device behavior, or someone knowing private details they should not know. These clues are not proof of spyware: ordinary technical issues can cause device symptoms, and a phone may show no obvious sign of covert monitoring.
Stalkerware may be concealed under an innocuous app name. A symptom check or scan cannot conclusively establish that spyware is present or rule it out. The Coalition Against Stalkerware explains the issue and offers survivor-focused guidance at stopstalkerware.org.

What to do if you think someone is monitoring your phone
If a partner, former partner, or another person may be monitoring your device, prioritize safety before changing settings, deleting apps, or resetting the phone. Those changes may alert the person and could escalate abuse.

- Plan before changing the phone. An advocate can help you consider immediate safety, evidence preservation, and whether a reset or replacement is appropriate.
- Be careful with backups. Restoring apps from an old backup could reinstall the software you are trying to remove.

What the term does not tell you
The name alone does not identify what information a particular app collects, whether it is installed on a specific phone, or whether its use is lawful where you live. Capabilities vary, detection is uncertain, and legal rules depend on jurisdiction and circumstances. If the concern involves possible abuse, seek safety support before trying to investigate or remove anything.
