Your phone knows more about you than any other device. It tracks your location, stores your messages, holds your photos, and manages your money. If someone installs spy software on it, they see everything.

What Is Spyware?

Spyware — sometimes called stalkerware — is software that secretly monitors your phone activity. It can track your calls, read your messages, record your location, access your camera, and even listen through your microphone.

Who Installs It?

In Africa, spyware is most commonly installed by intimate partners, but it can also come from malicious links sent via WhatsApp, SMS, or social media.

Warning Signs

  • Your battery drains faster than usual
  • Your phone is hot even when not in use
  • Unusual data usage spikes
  • Your phone takes longer to shut down
  • You see apps you do not recognise
  • Someone seems to know things they should not — your location, your conversations

How to Check — Android

  1. Go to Settings → Apps → Show all apps
  2. Look for apps with generic names you do not recognise
  3. Check Settings → Security → Device admin apps for unknown entries
  4. Review Settings → Accessibility for services you did not enable
  5. Check Settings → Network → Data usage for unknown apps using data

How to Check — iPhone

  1. Check Settings → General → VPN & Device Management for unfamiliar profiles
  2. Look for apps you did not install
  3. Check Settings → Privacy → Location Services for apps with "Always" access
  4. Check if your iCloud is signed in on unknown devices

What To Do If You Find Something

If you suspect an intimate partner installed spyware, do not confront them before securing yourself. Contact a trusted person first. Then:

  1. Screenshot evidence of the suspicious app
  2. Note the app name and permissions
  3. Consider whether removing it will alert the installer
  4. Contact SafeHer Foundation for guidance

Prevention

  • Use a strong screen lock (6-digit PIN minimum)
  • Never share your phone PIN
  • Disable "Install from unknown sources" on Android
  • Keep your OS updated
  • Review app permissions monthly

Your phone is your most personal device. Protect it like you would protect yourself.
