iPhone App Permission Auditor: See Which Apps Access Your Data
Guard is an iOS privacy app that audits all installed app permissions, reveals when they've been used, and flags suspicious access patterns - helping you answer whether apps are truly listening or watching without your knowledge.
What Guard's Permission Auditor Does
Guard scans your iPhone and presents a complete inventory of which apps have requested access to sensitive hardware: microphone, camera, location, contacts, photos, and calendar. Unlike Apple's native permission settings, Guard shows you not just what permission was granted, but when each app actually used it. You get a usage history - timestamps, frequency, and duration - so you can spot apps accessing your microphone at 3am or your camera without your interaction. This on-device analysis surfaces patterns humans miss: background activity, repeated access during idle time, and permission combinations that don't match the app's stated purpose.
Suspicious Activity Detection
Guard flags unusual access patterns using on-device analysis. If an app accesses your microphone consistently outside normal usage hours, or requests location data far more often than typical for its category, Guard alerts you. The app doesn't send data to a server - analysis happens locally on your device. Privacy score per app gives you a quick risk summary: a social media app requesting constant background location access, for example, will show a lower privacy score than expected. You can then decide whether to revoke that permission immediately or investigate further.
One-Tap Permission Control
Once you've audited your apps and identified unnecessary or suspicious permissions, Guard provides one-tap deep-links to iOS Settings so you can revoke access instantly. No need to navigate buried permission menus - Guard takes you directly to the specific app's permission controls. This is especially valuable if you've discovered an app has access it shouldn't: a note-taking app with full calendar access, or a weather app requesting microphone permission. Revoking is just one tap away, and you maintain full control over your device without removing apps entirely.
For Parents and Professionals
Parents managing children's devices can audit permissions to ensure installed apps aren't requesting suspicious access. Professionals handling client data or sensitive information use Guard to verify that communication and productivity apps aren't leaking microphone or camera access in the background. The privacy score per app helps non-technical users understand risk at a glance. For teams, understanding app behaviour builds confidence that devices remain secure during remote work or field operations.
Free Audit, Pro Monitoring
Guard's free tier gives you full access to the permission auditor and usage history - enough to understand your current app landscape. The Pro tier unlocks ongoing background monitoring, so Guard continuously watches for new suspicious patterns and alerts you in real-time, plus family device management for parents. Both tiers run analysis on-device, keeping your audit data private.
Privacy-First Design
Guard analyses app behaviour locally on your iPhone. No audit results, permission histories, or suspicious-activity flags are sent to external servers. This on-device approach means you get instant visibility into app surveillance without trading your privacy data to a monitoring service. As Guard's tagline says: your data, your rules.

Frequently asked questions
Does Guard let me see if an app is listening to me?
Guard shows you microphone access history, timestamps, and frequency - so you can see when apps requested or used your microphone. It flags suspicious patterns like unexplained background microphone access, but it cannot record or decode audio itself.
Can I revoke app permissions with Guard?
Yes. Guard provides one-tap deep-links to iOS Settings for each app's permission controls, so you can revoke camera, microphone, location, or other access instantly from Guard's interface.
Does Guard send my audit data to a server?
No. All permission auditing and suspicious-pattern detection happen on-device. Your audit results and usage history remain private on your iPhone.
Is Guard a personal safety or panic button app?
No. Guard is a data privacy app focused on understanding app surveillance and controlling permissions. It is not a personal safety application.
What's the difference between free and Pro?
Free includes the full permission auditor and usage history. Pro adds ongoing background monitoring with real-time alerts and family device management for parents.
Can I use Guard to monitor my child's iPhone?
Yes. Pro includes family device management, so parents can audit permissions on children's devices and receive alerts if suspicious patterns emerge.
