Title: Privacy Policy — Intruder Catcher Effective date: 3 May 2026
Introduction
This Privacy Policy describes how the "Intruder Catcher" Android application ("the App", "we", "us", or "our") handles information when you use it on your Android device. The App is published by Mohammad Arshi Khan.
The App is designed with a strict on-device privacy model: nothing the App accesses or generates is ever transmitted off your device, sold, shared, or analysed by us or any third party. We do not operate any servers and we do not have access to your captures or any other information from your device.
Summary
We do not collect any personal data.
We do not transmit any data off your device.
We do not share any data with third parties.
We do not show ads.
We do not use analytics or tracking SDKs.
Everything the App captures (photos, audio, location stamps, metadata) is stored only in private storage on your device, accessible only by you and only through the App itself.
Information the App Accesses
To provide its core feature — silently photographing someone who enters the wrong unlock code — the App accesses the following information on your device:
Camera — used to capture a single still image with the front camera each time the configured wrong-attempt threshold is reached.
Microphone (optional, can be disabled in Settings) — used to record a short ambient audio clip of approximately 3 seconds at the moment of capture.
Approximate and precise location (optional, can be disabled in Settings) — used to stamp each capture with GPS coordinates so you can identify where the failed unlock attempt happened. Location is fetched once per capture, used immediately, and saved alongside the photo.
Battery level — read at the moment of capture and saved as supplementary metadata.
Failed unlock attempt notifications — received from the Android operating system through the Device Administrator API ("Watch login attempts" policy) so the App knows when to trigger a capture.
Notification posting — used to display the mandatory foreground-service notification that Android requires whenever an app uses the camera, microphone, or location from the background.
The App does not access your contacts, messages, call logs, browser history, calendar, files outside its own private folder, accounts, advertising ID, device identifiers, or any other personal information.
How the Information Is Used
All accessed information is used solely to construct a "capture record" — a photo plus optional audio clip plus optional location and timestamp — that is saved to the App's private storage on your device. The capture record is then displayed to you, and only you, in the App's Gallery and Detail screens. The information is never sent off your device by the App.
Data Storage, Retention, and Deletion
Captures (photos, audio, and metadata) are stored in the App's private storage area on your device. This area is sandboxed by Android — no other app on your device can read it.
Data is retained until you choose to delete it. You can:
Delete an individual capture from the Detail screen using the trash icon.
Delete all captures at once from the Gallery screen using the trash icon in the top bar.
Uninstall the App, which removes all captures and all App data from your device.
Because nothing leaves your device, there is no remote copy of your data and nothing for us to delete on a server. All deletion is immediate and complete.
Data Sharing
The App does not share your data with any third party. Specifically:
No data is uploaded to any cloud service or server.
No data is sold, rented, or transferred for any commercial purpose.
No third-party analytics, advertising, crash-reporting, or tracking services are integrated.
The only way a capture leaves the App is if you yourself explicitly tap the Share button on the Detail screen, which lets you send the photo to another app of your choice (for example, your email or messaging app). What you do with the file after that is your decision and is governed by the privacy policy of whichever app you share it with.
Permissions Explained
When you install or first run the App, Android will ask you to grant the following permissions. Each is used only for the purpose stated below.
CAMERA — to take the silent photo of whoever entered the wrong unlock code.
RECORD_AUDIO — to record the optional 3-second ambient audio clip. Disable in Settings to revoke this use.
ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION — to stamp captures with GPS coordinates. Disable in Settings to revoke this use.
POST_NOTIFICATIONS — to show the mandatory foreground-service notification while a capture is in progress (required by Android, cannot be hidden by the App).
FOREGROUND_SERVICE, FOREGROUND_SERVICE_CAMERA, FOREGROUND_SERVICE_MICROPHONE, FOREGROUND_SERVICE_LOCATION — to legally use the camera, microphone, and location from a background-triggered service on Android 11 and newer.
RECEIVE_BOOT_COMPLETED — to re-initialise notification channels after your device reboots, so captures continue to work without you having to open the App.
REQUEST_IGNORE_BATTERY_OPTIMIZATIONS — to let you whitelist the App from Android's battery optimisations, so the OS does not suspend captures while the screen is off.
The App also requests the Device Administrator "Watch login attempts" policy. This policy lets the App receive a callback from the operating system when a wrong PIN, pattern, or password is entered on the lock screen. The App does not request and does not use any other Device Administrator capability — it cannot lock your device, wipe your data, change your password, or restrict any other app or function. You can revoke Device Administrator status at any time from Android Settings → Security → Device admin apps.
Security
All capture data is stored in Android's app-private internal storage, which is isolated from other apps by the operating system. We additionally disable cloud backup of the App's data so that captures are not copied off your device by Android's automatic backup system.
Because the App does not transmit data over the network, encryption-in-transit does not apply. There are no servers or accounts to protect.
Children's Privacy
The App is not directed at children under 13 and we do not knowingly collect any information from anyone, of any age, on or off our service. The App is intended to be used by the legitimate owner of the device on which it is installed.
Your Responsibilities
The App is intended for use on your own personal device by you, the device's legitimate owner, to identify someone who attempts to access your device without permission. Photographing or audio-recording other people without their knowledge or consent may be regulated or prohibited under the laws of your country, state, or region. You are solely responsible for complying with all applicable laws regarding the captures generated and retained by the App, and for any consequences of sharing or otherwise using those captures.
Changes to This Policy
We may update this Privacy Policy from time to time, for example to reflect changes in the App's features or in applicable law. When we make material changes, we will update the "Effective date" at the top of this page. Continued use of the App after a change constitutes acceptance of the updated policy.
