What stalkerware does
Stalkerware (sometimes called spouseware or a "monitoring app") can record location, read messages, log calls and sometimes switch on the microphone or camera. Unlike most malware, it is not trying to steal money. It is used to watch a specific person.
Warning signs on Android
- An app you do not remember installing, often with a bland name like "System Service" or "Sync".
- Battery drains faster than usual, or the phone feels warm when idle.
- Unexpected spikes in mobile data use.
- Settings that changed on their own, such as Install unknown apps being turned on, or Google Play Protect being turned off.
- An app that has Accessibility or Device admin access that you never granted.
How to check
- Open Settings, then Apps, and look through the full list, including system apps.
- Open Settings, then Accessibility and check which services are switched on.
- Open Settings, then Security, then Device admin apps.
- Check Install unknown apps to see which apps are allowed to install other apps.
If you find it
Think about your safety before removing it. Removing stalkerware can alert the person who installed it. If you may be at risk, contact a trusted person or a local support service first. In India you can reach the National Cyber Crime Helpline on 1930 or report at cybercrime.gov.in.

Frequently asked questions
Can stalkerware be installed without touching my phone?
It is uncommon. Most stalkerware needs physical access to install, or needs you to be tricked into installing an app from outside the Play Store.
Will a factory reset remove it?
Usually yes, but back up only what you need, and be careful not to restore the unwanted app from a backup.
