Anti Spy Detector - Spyware

Concerned that someone may be monitoring your phone? Anti Spy is a spyware detector and anti-spyware scanner for Android. Check installed apps for spyware, stalkerware, keyloggers and hidden spy apps. See detected risks, understand the finding and decide what to remove.

Start with free manual scans. Pro adds real-time protection, AI-supported detection and automatic background scans between your own checks. No ads.

When to check your phone for spyware
• You are concerned about unwanted monitoring of your messages or location
• You find an unfamiliar app or install software from outside Google Play
• You want to review the apps on a used phone before making it your own
• You want to check installed apps after changes to your device

What Anti Spy detects
• Spyware and known surveillance tools in installed apps
• Stalkerware used to monitor someone without consent
• Hidden or disabled spy apps, even without a visible launcher icon
• Keyloggers that can record what you type
• Malicious apps that monitor text messages (SMS) or GPS location
• Banking trojans, backdoors and potentially unwanted apps

Remove spyware on your terms
See which app was detected and why it may be a risk. Review the finding and decide what to uninstall. Android may ask you to confirm or to turn off device administrator access first. After removal, run another scan to check the result. You stay in control of each step.

Signatures and AI
Free scans compare installed apps with signatures of known spyware, supported by Protectstar AI CLOUD. Advanced detection combines signatures with AI-supported analysis through Protectstar Dual Engine and Deep Detective™. Pro includes enhanced AI CLOUD features. Keep the app and detection data updated.

Why keep Anti Spy on your phone
A manual scan checks your phone when you start it. New apps and updates can change what is installed later. Free lets you repeat a scan whenever you choose. Pro adds real-time protection and automatic background scans, so you do not have to start every check yourself.

Choose Pro if you want ongoing automatic checks alongside your manual scans. The added value is continued checking as your apps change, including after an earlier scan found nothing suspicious.

Choose your edition
• Free: manual, signature-based spyware scans. No root, no Protectstar account, no time limit.

Tests and validation
In AV-TEST's January 2024 Android malware test, Anti Spyware 6.0 achieved 99.8% real-time protection against Android malware attacks and 100% detection of widespread Android malware.
Protectstar reports DEKRA MASA L1 (Verified Self) validation of version 6.7.5 dated 20 February 2026. It assessed selected OWASP MASVS app-security requirements, not detection rates.

Privacy without ad tracking
No ads, advertising IDs or third-party tracking SDKs. The privacy policy and Google Play Data safety section explain which data the security features process and why.

Good to know
• Anti Spy checks software, not physical trackers or hidden cameras.
• A scan with no findings found nothing suspicious in that check. No scanner rules out every threat; an unfamiliar app or permission alone does not prove spying.
• If an abusive person may be monitoring you, seek help from a safer device before scanning or changing settings. Those actions may alert them.

Run a spyware scan, review the findings and choose the protection that suits you.
