How it works

Three simple steps. Takes about 5 minutes. You get a full report you can trust.

1

Start the scan

Open the app and tap Check Device. Trust Phone automatically reads your battery, storage, and device info right away — no setup, no account.

2

Run the interactive tests

Some tests need your input — swipe the touchscreen, look at each camera, press the buttons, or plug in a cable. Each test has clear, simple instructions.

3

Read your report

Every test produces a clear pass/fail result with details. Your full scan report is saved on the device so you can refer to it before any sale or purchase.

Everything that matters, tested

Trust Phone checks all the hardware a buyer or seller actually cares about.

Battery

Health status, USB charging port test, and wireless charging detection.

Display

Dead pixel detection across 5 full-screen colors — black, red, green, blue, white.

Touchscreen

Multi-round swipe test covering every zone — detects dead spots and ghost touches.

Cameras

Tests every camera — front and rear — with a live preview and image quality check.

Connectivity

Wi-Fi, 4G/5G, Bluetooth, NFC, SIM slots, and eSIM support — all in one screen.

Hardware

Volume buttons, loudspeaker, earpiece, microphone, vibration, and biometric sensors.

Sensors

GPS accuracy test, compass/magnetometer, gyroscope, accelerometer, and ambient light.

Performance & Storage

RAM usage, memory responsiveness, total and available storage — real numbers, not estimates.

Your data never leaves your phone

Scan reports are stored only on your device, encrypted with AES-256. No account, no cloud upload, no ads. We use Firebase only to collect anonymous crash reports so we can fix bugs — nothing personal is ever sent.

Privacy Policy

Last updated: May 8, 2026

1. Who we are

Trust Phone is developed and maintained by Citvo. If you have any questions about this privacy policy or how your data is handled, you can reach us at contact@citvo.com.

2. What data we collect and why

Scan reports (stored only on your device)

When you run a scan, Trust Phone reads hardware information from your device — battery health, storage capacity, sensor availability, camera specs, and test results. This data is saved exclusively on your device in encrypted local storage. It is never uploaded to our servers or any external service.

Anonymous crash and performance data (Firebase)

We use Firebase Crashlytics and Firebase Performance (by Google) to collect anonymous reports when the app crashes or performs unexpectedly. These reports help us identify and fix bugs. They do not contain your name, email, phone number, or scan results. They may include device model, Android version, and app version.

We also use Firebase Analytics to understand how features are used in aggregate — for example, which screens are visited most often. This data is anonymised and not linked to any individual.

What we do NOT collect

  • Your name, email address, or any account information
  • IMEI, IMSI, SIM serial number, or any persistent device identifier
  • Your contacts, call logs, or messages
  • Any photos or videos taken during camera tests
  • Any audio recorded during the microphone test — it is deleted immediately after playback
  • Your precise or approximate location beyond what is temporarily needed for the GPS test

3. Permissions explained

Trust Phone requests the following permissions. Each one is used only during its specific test and for no other purpose.

Camera

Used to display a live preview during the camera test — to confirm each lens can open correctly. No photos or videos are captured or saved.

Microphone

Used to record a 5-second audio clip during the microphone test. The recording is played back immediately so you can hear your voice, then deleted. It is never saved to storage or sent anywhere.

Location (GPS)

Used only during the GPS test to check whether the device can obtain a satellite fix. Location is never stored, shared, or used outside of this test screen. You can skip this test entirely.

Bluetooth

Used to check whether Bluetooth hardware is present and can be enabled. No device pairing, scanning for other devices, or data transfer occurs.

Phone state (network type)

Used on Android 12 and below to detect whether your device is on 4G or 5G. No call information, phone number, or personal identifiers are accessed.

Notifications

Requested on Android 13+ to allow us to send occasional notifications about new features and updates. You can turn these off at any time in your device settings.

4. Third-party services

Trust Phone uses the following third-party services provided by Google:

  • Firebase Analytics — anonymous usage statistics
  • Firebase Crashlytics — anonymous crash reports
  • Firebase Performance — anonymous app performance data
  • Firebase Cloud Messaging — push notifications

These services are governed by Google's Privacy Policy. We do not share any data with other third parties for advertising, analytics, or any other commercial purpose.

5. Data security

Scan reports saved on your device are encrypted using AES-256-GCM via the Android Keystore, with HMAC-SHA256 tamper detection. The encryption key is stored in secure hardware and never leaves your device. We apply reasonable technical measures to protect any data we do process against unauthorised access, loss, or disclosure.

6. Data retention

Scan reports are kept on your device until you manually delete them within the app (up to 3 reports). Uninstalling the app removes all locally stored data. Anonymous crash and analytics data collected by Firebase is retained according to Firebase's data retention policy.

7. Children's privacy

Trust Phone is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, please contact us and we will take steps to remove it.

8. Your rights (GDPR / EEA users)

If you are located in the European Economic Area, you have the right to:

  • Access the personal data we hold about you
  • Request correction or deletion of your personal data
  • Object to or restrict the processing of your data
  • Withdraw consent at any time (where processing is based on consent)

Since we do not collect personal data directly, most of these rights apply to the anonymous data held by Firebase. You can exercise your rights by contacting us or directly through Google's privacy controls.

9. Changes to this policy

We may update this privacy policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of Trust Phone after changes are made constitutes acceptance of the updated policy.
