Privacy Policy

Last updated: 15 July 2026

LubeLogger mobile is an unofficial, open-source Android companion app for a self-hosted LubeLogger server that manages vehicle maintenance records. It is not affiliated with, endorsed by, or connected to LubeLogger or Hargata Softworks.

This policy explains what data the app handles. In short: LubeLogger mobile does not collect, transmit, or share any personal data with the developer or any third party. All data stays on your device and travels only to the LubeLogger server address that you configure.

Who the app talks to

LubeLogger mobile communicates only with the self-hosted LubeLogger server whose address you enter during setup. There is no cloud backend, no analytics service, and no advertising SDK. The developer never receives your data.

Data stored on your device

  • Server address and API key for your LubeLogger server. The API key is stored in the Android Keystore-backed encrypted storage on your device and is never sent anywhere except to your own server, over the connection you configure.
  • App settings and preferences — such as display units, which record tabs are shown, and notification preferences — stored in local app storage.

This data is removed when you uninstall the app or clear its storage.

Permissions and why they are used

  • Internet — to reach the LubeLogger server you configure. This is the only network destination the app contacts.
  • Notifications — used only if you opt in to reminder notifications, so the app can alert you when a maintenance reminder is due or overdue.
  • Background scheduling / run at startup — when reminder notifications are enabled, the app periodically checks your server for due reminders in the background and re-registers that check after a device restart. No data leaves your device beyond the connection to your own server.

Files and attachments

When you attach a document or photo to a record, the file you pick is uploaded to your LubeLogger server and attached to that record. When you open an attachment, it is downloaded from your server to your device so it can be viewed. Files are exchanged only with your own server.

Children

LubeLogger mobile is a utility app for vehicle owners and is not directed at children.

Data deletion

Because no data is collected on any server operated by the developer, there is nothing for the developer to delete. To remove all locally stored data, uninstall the app or clear its storage in Android settings. Data held by your LubeLogger server is governed by that server, which you control.
