Privacy Policy
Last updated: August 18, 2026
Device-Test is designed as a local-first hardware testing utility. Live camera, microphone, location, sensor, clipboard, biometric, NFC, Bluetooth, and device test results are not uploaded to our servers. The website does use limited analytics, advertising, and consent preferences as described below.
1. Scope
This Privacy Policy applies to the Device-Test website at device-test.com and the Device Test Android app, package name com.devicetest.app. It explains what device data may be accessed when you run specific tests, what website service providers may receive, how information is used, and how long it is kept.
2. Data Collection Summary
We do not operate user accounts or cloud sync for device test results. Most information shown in a browser test or the Android app is read from your device only after you choose a test and, where required, grant permission. The Android app does not include third-party advertising or analytics SDKs; the website uses the services listed in Section 3.
- No account is required.
- No app analytics SDK, advertising SDK, or crash reporting SDK is used by the Android app.
- No camera images, microphone audio, location coordinates, Bluetooth scan results, NFC tag data, clipboard content, or biometric templates are uploaded by us.
- Recent test shortcuts may be stored locally on your device to improve navigation.
3. Website Data, Cookies, Analytics, and Advertising
When you visit the website, our hosting infrastructure and service providers may receive standard request information such as IP address, browser and device type, referring page, requested URL, and timestamps. We use this information to deliver the site, maintain security, and diagnose availability problems.
- Consent preferences: the website stores your cookie choice in your browser so it can remember whether you accepted or rejected optional categories.
- Analytics: when enabled, the website may load analytics from
analytics.codegram.devto understand aggregate page usage and improve the service. - Advertising: the website loads Google AdSense. Google and its partners may use cookies or similar technologies to deliver, measure, and limit advertising, subject to your consent choices and Google’s policies.
- Fonts and linked resources: the website may request fonts or other public resources from third-party hosts, which can receive standard network request metadata.
These website services are separate from the live hardware test data. We do not intentionally send camera frames, microphone audio, test results, location coordinates, or nearby device scan results to analytics or advertising providers.
4. Permissions and Device Data Used by Test Features
| Feature | Data accessed | How it is used |
|---|---|---|
| Camera, flashlight, and camera preview tests | Camera permission, camera device list, live preview, torch control | Used only to show a live preview, enumerate cameras, or test flashlight behavior on your device. We do not record, save, or upload photos or video. |
| Microphone and speech tests | Microphone permission, audio level readings, speech recognition input | Used to show microphone activity or test speech recognition. We do not record or upload audio. Speech recognition may use Android or device-provided speech services depending on your device settings. |
| Speaker and text-to-speech tests | Audio output, text-to-speech engine, a public test audio file | Used to play audio through your speaker or device TTS engine. The speaker test may request a public audio file from https://actions.google.com/; that host may receive standard network request metadata such as IP address. |
| Location and Wi-Fi tests | Approximate/precise location permission, Wi-Fi SSID/BSSID/IP information, nearby Wi-Fi permission where Android requires it | Used to display GPS and Wi-Fi diagnostics in the app. We do not upload location, Wi-Fi names, BSSIDs, IP addresses, or nearby network information. |
| Bluetooth and NFC tests | Bluetooth scan/connect permission, nearby BLE device information, NFC tag availability and tag data during a scan session | Used to verify whether Bluetooth and NFC features work. Results are shown locally and are not uploaded by us. |
| Sensors and motion tests | Accelerometer, gyroscope, compass, ambient light, proximity, barometer, pedometer/activity recognition, brightness, display, touch, gamepad, vibration, battery, and volume data | Used to display real-time device capability and status information. These readings stay on your device and are not sent to us. |
| Device information and system checks | Device model, operating system version, hardware details, notification permission status, clipboard test content, biometric capability status | Used to help you confirm device capabilities. Clipboard content is only displayed when you choose the clipboard test. Biometric authentication is handled by the operating system; the app does not receive biometric templates. |
5. Local Storage
The app may save a small list of recently opened tests on your device so the home screen can show recent shortcuts. This data is stored locally in the app's private storage area and is not sent to us. You can remove it by clearing the app's storage in Android settings or uninstalling the app.
6. Sharing and Sale of Data
We do not sell personal data. We do not share personal or sensitive user data with advertising networks, analytics providers, or data brokers. The Android app does not include third-party advertising, analytics, or crash reporting SDKs.
Some device functions are provided by Android or device manufacturer services, such as biometric authentication, speech recognition, text-to-speech, and permission dialogs. Those services are controlled by your device settings and the service providers' own policies.
7. Network Access
The app requests Internet/network permissions primarily for connectivity-related diagnostics and for the speaker test audio file described above. We do not use Internet access to upload your test results to our servers.
8. Data Retention and Deletion
We do not retain app test results on our servers because the Android app does not send those results to us. Locally stored recent test shortcuts remain on your device until you clear app storage or uninstall the app.
9. Children
Device Test is a general utility app and is not directed to children. We do not knowingly collect personal data from children.
10. Security
The app is designed to process test data locally on your device. When the app makes network requests, it uses HTTPS URLs where applicable.
11. Changes to This Policy
We may update this Privacy Policy when the app's behavior, permissions, or legal requirements change. The updated policy will be posted at this URL with a new "Last updated" date.
12. Contact
