What Is a Privacy Risk Score and How Does Guard Calculate Yours
A privacy risk score is a rating that shows how exposed your iPhone is based on the permissions you've granted to installed apps. Guard by MRVL gives every app on your phone a privacy risk score, then walks you through revoking the ones that worry you.
How Guard Defines Privacy Risk Score
Guard assigns a privacy risk score to each app by looking at what permissions it requests and how sensitive those permissions are. An app that asks for access to your location, contacts, and photos gets a higher risk score than one that only needs basic functionality. The score is displayed in the Free dashboard for 12 common apps, so you can see at a glance which ones pose the biggest exposure. The higher the score, the more personal data that app could potentially access. Guard doesn't just flag the risk; it shows you exactly which permissions are driving that score.
Why Your Privacy Risk Score Matters
Most iPhone users grant permissions without thinking about the long-term implications. A weather app that requests location access makes sense. A social media app that asks for your microphone, contacts, and clipboard access raises red flags. Your privacy risk score helps you understand the cumulative exposure across all your installed apps. In 2025 and beyond, privacy has become a serious concern for professionals handling sensitive data, parents monitoring children's devices, and anyone who simply wants to know what apps can see. Guard translates technical permission settings into a number you can understand and act on.
How to Check Your App's Privacy Risk Score in Guard
Open Guard and browse the dashboard. Each of the 12 common apps shown in the Free version displays its privacy risk score prominently. Tap on any app to see the specific permissions it requests. If you spot a high-risk app, Guard gives you a direct link into iOS Settings where you can revoke permissions on the spot. The Personal Pro tier upgrades this with real-time alerts whenever an app tries to change its permission status, plus a full data exposure profile and tracking breakdown so you can see exactly what each app has accessed. Family tier extends this protection across six devices and includes child controls, so parents can monitor what apps their children are using and revoke risky access remotely.
What Guard's Privacy Risk Score Can and Cannot Do
Guard's privacy risk score is educational and empowering, not a comprehensive audit of every app on your phone. The Free version covers 12 common apps; the score reflects which permissions those apps request, not a real-time scan of your entire device. iOS sandboxing prevents third-party apps from scanning other apps' actual permission usage, so Guard uses a curated set of well-known apps and their known permission patterns. Think of it as a guided tour through the most dangerous permission requests, not a surveillance detector. Guard is not antivirus software, a VPN, or a tool to detect microphone or camera surveillance. Its job is to show you where you've granted permission and help you take back control.
Privacy Risk Score and Personal Data Exposure
Once you understand your privacy risk score, you can make informed decisions about what stays on your phone and what goes. Revoking a permission doesn't uninstall the app; it just blocks access. Guard makes this simple by deep-linking directly to iOS Settings so you don't have to hunt through menus. Personal Pro users see even more detail: a clipboard safety check reveals which apps have accessed your clipboard, tracking details show which apps have requested tracking permission, and a permission breakdown chart visualises your exposure across all categories. For parents, the Family Hub adds a layer of oversight. Monitoring your child's privacy risk scores can spark conversations about why apps need certain permissions and what data they're really after.

Frequently asked questions
What does a high privacy risk score mean for an app
A high score means the app requests access to sensitive data like location, contacts, photos, or clipboard. It doesn't mean the app is malicious, but it does mean you should decide whether the app actually needs that access to do its job.
Can Guard scan all the apps on my iPhone
The Free version covers 12 common apps with a demo dashboard. iOS restrictions prevent Guard from auditing every app on your device in real-time, so Guard focuses on the most frequently used and most permission-heavy apps to give you the clearest picture of your exposure.
How do I revoke permissions for an app with a high privacy risk score
Tap the app in Guard's dashboard, then tap the permission you want to revoke. Guard deep-links directly into iOS Settings where you can toggle the permission off. You keep the app; you just block its access to that specific data.
What's included in Guard Personal Pro beyond the privacy risk score
Personal Pro adds real-time alerts when apps request new permissions, a clipboard safety check, a data exposure profile, and tracking details per app. You also get a visual permission breakdown chart so you can spot patterns across all your apps.
Is Guard a virus or spyware detector
No. Guard is a privacy education tool that shows you which permissions you've already granted to apps. It's not antivirus software and doesn't detect malware or spyware. It helps you understand and control your own permission settings.
Can I monitor my child's privacy risk score with Guard
Yes. The Family tier gives you a 6-device family hub where you can view privacy risk scores across your child's devices and revoke permissions remotely, so you can help them understand what apps are asking for and why.
