This Privacy Policy describes how DACK Systems, Inc. ("we", "our", or "us") handles information in the X-Track mobile application (the "App").
The App does not collect, transmit, or store any personal information on our servers. All data generated by the App remains on your device or on the X-Track hardware device you own.
The following information is processed locally on your device:
The App uses Bluetooth to discover and connect to X-Track hardware and receive tire readings. On Android 11 and earlier, the App collects Bluetooth Low Energy (BLE) scan results that Android classifies as location data. This data enables X-Track device discovery while the App is visible and, when background monitoring is enabled, tire-sensor monitoring, automatic reconnection, and tire alarms even when the App is closed or not in use.
On Android 9 and earlier, the same location permission also covers background Bluetooth scanning when you enable monitoring; these versions do not provide a separate background location permission.
Background monitoring and notifications are off by default. If you choose to enable them on Android 10 or 11, the App requests background location permission solely to continue this Bluetooth scanning while the App is closed or not in use. X-Track does not use GPS coordinates. Bluetooth scan data is processed on your device and is not transmitted or shared.
On Android 12 and later, the App instead uses the Nearby devices permission for Bluetooth scanning and connections; no location permission is requested. On Android versions that control notifications through a system permission, that permission is requested only when you enable background monitoring.
On iOS, the App requests Bluetooth access to discover and connect to X-Track hardware and receive tire readings. If you enable background monitoring, Bluetooth can continue maintaining the connection and receiving readings while the App is not in use. Notification access is used to display tire alarms. X-Track does not request location permission on iOS.
The App periodically contacts our server (systemesdack.ca) to check whether a
firmware update is available for your X-Track hardware. This request contains no personal
information — only the current firmware version string is compared against the latest published
version.
The App includes a "Send logs" button. Pressing it opens your device's standard share sheet, allowing you to send the local log file to a destination of your choosing (e.g. email, messaging app). Logs are only transmitted when you explicitly initiate this action. If you choose to send logs to our support team, we use the information solely to diagnose the reported issue and do not share it with third parties.
The App does not integrate any third-party analytics, advertising, or tracking SDKs.
Since all data is stored locally on your device, you can remove it at any time by uninstalling the App or by clearing the App's data in your device settings. Uninstalling the App removes all locally stored configuration and logs.
The App is not directed at children under the age of 13. We do not knowingly collect any information from children.
We may update this Privacy Policy from time to time. Any changes will be reflected by an updated date at the top of this page. We encourage you to review this policy periodically.
