Privacy Policy
Intruder Alert (“the App”) is a motion-based alarm that runs on your phone. This policy explains what information is involved, where it stays, and what we do not collect.
1. Who we are
The App is published by Smartklik, računalniško programiranje in svetovanje, Marko Lovrić s.p. (short name: Marko Lovrić s.p.), Goriče 30, 4204 Golnik, Slovenia (registration no. 7508417000, tax no. 91312434). Full company details are on the Legal notice page. Privacy questions: info@smartklik.si or Support.
2. Core principle: local-first
Alarm settings, PIN material, event log entries, and purchase/trial status related to unlocking are stored on your device (Android DataStore / internal storage). The App does not require an account and does not operate its own cloud backend for motion data, camera images, or location history.
3. Data processed on your device
Settings and preferences
- Alarm mode (Door / Backpack), sensitivity, arming delay
- Sound, vibration, flash, stealth preferences and volume
- Theme preference
- Optional custom alarm sound file (copied into app-private storage)
Security
- App PIN stored as a salted hash (PBKDF2), not as plain text
- Biometric unlock uses the device’s biometric APIs; biometric templates stay in the system secure hardware and are not readable by the App
Event log
- Recent trigger/test events with timestamps (limited local history)
Sensors (runtime only)
- Accelerometer and (if available) gyroscope readings are used in real time to detect motion while armed
- These readings are not uploaded and are not stored as a continuous recording
Trial and unlock
- Local markers for trial start and unlock status
- One-time purchase is handled by Google Play Billing; Google processes payment data under Google’s policies
4. Permissions (why we ask)
- Vibrate — haptic alerts and stealth mode
- Notifications — foreground service status while monitoring
- Foreground service / wake lock — keep motion monitoring reliable with the screen off
- Biometric — optional unlock to disarm
- Billing — lifetime unlock purchase via Google Play
Flash uses the torch API and does not require a Camera permission for taking photos. The App does not request access to your contacts, SMS, microphone recording, or fine location for the core alarm.
5. This website
The marketing site is static HTML. Hosting providers may process standard server logs (IP address, user agent, timestamps) according to their own policies. We do not embed advertising trackers or analytics SDKs in the App for behavioural profiling. If this website later adds analytics cookies, this section will be updated.
6. Children
The App is not directed at children under 13 (or the equivalent minimum age in your country). We do not knowingly collect personal information from children.
7. Retention and deletion
Local data remains until you clear app storage, uninstall the App, or change settings that overwrite it. Uninstalling removes app-private data on the device. Purchases can be restored with the same Google account via Play.
8. Your rights (EEA/UK and similar)
Because most processing happens on your device under your control, the primary way to exercise access or deletion is through Android settings (clear data / uninstall). For questions about this policy or Play purchase records, contact us using the Support page. You may also have the right to lodge a complaint with your local supervisory authority.
9. Changes
We may update this policy when the App or website changes. The “Last updated” date at the top will change accordingly. Material changes may also be noted in the Play Store listing release notes.
