Privacy Policy - USB Alarm

1. Introduction

Lavazzi.it Srl ("we", "our" or "us") is committed to protecting the privacy of users of the USB Alarm mobile application ("the App"). This Privacy Policy describes what data the App processes and how.

By using USB Alarm, you agree to the practices described in this Privacy Policy. If you do not agree with this policy, please do not use the App.

2. Data We Process

USB Alarm does NOT collect, transmit, or share any personal data with the developer or with third parties. The App runs entirely on the device, with no connection to external servers.

The only data saved is stored exclusively on the user's device, in a private area of the App, and consists of:

• Security PIN: never saved in plain text. Only a cryptographic hash is stored (PBKDF2 with a random salt), which does not allow the original PIN to be recovered.
• App preferences: protection on/off status, sound/vibration/volume preferences, and whether the alarm should only trigger when the screen is locked.

This data is not included in the device's cloud backups (it is explicitly excluded from Android's backup rules) and is deleted when the App is uninstalled.

3. Permissions Requested and Why

USB Alarm requires the following permissions to function correctly:

Permission	Reason
Notifications (POST_NOTIFICATIONS)	Show the "protection active" status notification and the alarm alert.
Vibration (VIBRATE)	Vibrate the device during the alarm.
Auto-start (RECEIVE_BOOT_COMPLETED)	Re-enable protection after a reboot, if it was active.
Foreground service (FOREGROUND_SERVICE, "specialUse" type)	Keep listening for charger disconnection even when the App is not in the foreground.
Full-screen notifications (USE_FULL_SCREEN_INTENT)	Show the alarm even when the phone is locked.
Battery optimization exemption	Optional, can be enabled by the user from the App's Settings, to prevent the system from stopping background protection.

None of these permissions is used to collect, profile, or share data: they exist solely to make the alarm work as described.

4. Third-Party Services

The App does not integrate any analytics, advertising, or tracking libraries, nor any third-party SDKs that collect data.

5. Data Sharing with Third Parties

USB Alarm does NOT share any data with third parties, simply because it does not collect or transmit any data. Since no data is transmitted to external servers, no international data transfer takes place.

6. Data Retention and Deletion

The data saved by USB Alarm (PIN hash and preferences) remains on your device until you:

• Change or remove the PIN from the App's settings
• Clear the App's data from the device's settings
• Uninstall the App (in which case all local data is automatically deleted)

7. Children's Data

The App is not specifically directed at children and does not collect data from any user, whether a child or an adult.

8. Your Rights (GDPR)

Since USB Alarm does not collect, transmit, or otherwise process any personal data outside the user's device, most of the rights provided for by the General Data Protection Regulation (GDPR) do not apply in practice, as there is no processing of personal data on our part. You remain free at any time to:

• Delete the PIN and preferences from the App's settings
• Clear all App data from the device's settings
• Uninstall the App, which automatically removes all local data

9. Cookies and Tracking Technologies

USB Alarm does NOT use cookies, web beacons, or other tracking technologies. The App does not contain any analytics, advertising, or tracking systems of any kind.

10. Changes to This Privacy Policy

Any future changes will be published on this same page with an updated date. We recommend periodically reviewing this Privacy Policy to stay informed.

12. Severability Clause
