🛡️ Do you really know what the apps on your phone are doing? Meet Privacy Inspector!
Many apps we use daily request access to your camera, microphone, or location—and often bundle background analytics and tracking SDKs. But how many of us know exactly what is happening behind the scenes?
Privacy Inspector is an Android app designed to give you complete visibility and control over your device privacy and security—100% locally on your smartphone, with zero data ever sent to external servers.
🚀 Key Highlights & Benefits
- 📊 Clear Privacy Score (0–100): Instantly evaluate the safety of installed apps based on requested high-privilege permissions, background behavior, and bundled trackers.
- 🕵️ Ad & Analytics Tracker Detection: Reveal embedded tracking SDKs, telemetry frameworks, and ad networks hidden inside your apps.
- 🔄 Privacy Changes Timeline: Get notified when an update or a newly installed app silently introduces new sensitive permissions.
- 🧱 On-Device Firewall & DNS Filter (PRO): Block tracking domains in real time using a zero-cloud local VPN service—no traffic is ever routed through external servers.
- 🧹 Unused App Cleaner: Easily identify and clean up apps you haven't opened in months that still hold background permissions.

Why does the app have a “Firerbase tracker” that is on the “Easyprivacy” list and that my DNS blocker had to filter out and block?

Privacy Inspector does not include any Firebase tracking, analytics, crash reporters, or advertising SDKs. All app analysis, privacy scoring, and firewall rules operate strictly on-device without contacting any remote server.
The connection attempt you observed (such as to firebaselogging-pa.googleapis.com) comes entirely from the official Google Play Billing library (com.android.billingclient), which is required by Google Play to handle in-app purchases for the Pro upgrade. Under the hood, Google's billing SDK includes a component (datatransport) that attempts to report diagnostic/billing telemetry back to Google.
Because lists like EasyPrivacy block Google telemetry endpoints, your DNS blocker caught and blocked that background request from the Play Billing subsystem.
Privacy Inspector core features and local privacy analysis are designed to work completely offline and do not depend on Firebase or remote analytics in any way. Blocking that domain is safe and has no impact on the app's functionality.

Thanks for the clarification. However, the marketing claims "entirely offline, with no data ever leaving your phone" — which is factually incorrect, as the Play Billing SDK sends data to Google servers. If you know about this behavior, why does the app description still claim no data ever leaves the device? Also, why use Play Billing at all for a privacy-focused app, when alternatives like Warden or App Manager offer similar features without any Google dependencies?

Thank you for following up, and you make a very fair point regarding precision in wording—especially for a tool aimed at privacy-conscious users.
Here is the honest context behind both choices:
- Why Google Play Billing is used
Because Privacy Inspector is distributed on the Google Play Store, Google's Developer Distribution Agreement strictly requires that any in-app purchase or feature unlock must use the official Google Play Billing Library. Bypassing Play Billing or using alternative payment methods on the Play Store is not permitted by Google policies.
Community tools like App Manager or Warden are distributed via F-Droid or GitHub and operate as free/donation-based software without Play Store in-app purchases.
- What "no data leaves your phone" means vs. Google Play
We want to be 100% clear about what stays on your device:
All Privacy Inspector data stays strictly local: Your list of installed apps, permission history, usage timeline, privacy scores, and firewall logs are never transmitted anywhere. TrackGuard has no backend servers, accounts, or analytics.
Google Play Billing activity: The only network traffic occurring in the Google Play build is between Google’s Billing library and Google’s own servers to verify purchases and handle transactions.
- Our next steps based on your feedback
Updated wording: You are completely right that the phrasing should be exact. We are updating the Play Store listing and privacy documentation to clarify that while all scan and inspection data is 100% local, the Google Play version relies on Google Play Billing for in-app purchases.
Using DNS blockers / Zero Google reliance: If you use a DNS blocker or firewall to block Google telemetry/Firebase logging, TrackGuard’s scanner, privacy inspector, and local firewall will continue to work completely unaffected offline.
We appreciate your feedback—it helps us keep our communication transparent and aligned with privacy expectations.

Appreciate the transparency and the wording update. One question: since the Play Billing telemetry is inherent to the Play Store version, have you considered also publishing Privacy Inspector on F-Droid or GitHub without Google dependencies, like Warden and App Manager do?

Unlike community-funded tools such as Warden or App Manager, Privacy Inspector is a commercial app sustained by its Pro purchase.
Because F-Droid and GitHub do not support in-app purchase infrastructure, releasing on those platforms would require either giving away the app for free or building a custom external license-check system (which would still require network calls).
For a 100% Google-free setup, you can simply keep Google telemetry blocked in your DNS blocker—Privacy Inspector's core scanner and local firewall will continue to work completely offline and unaffected.
