# BUS Core Privacy Statement

Last updated: March 2026

BUS Core is designed to run locally on your machine.
Because of this architecture, the software collects little or no personal data.

---

## Local Operation

All operational data is stored locally in a **SQLite database** on your device.

Examples include:

* inventory records
* manufacturing recipes
* cost data
* production logs
* sales records

This data is not transmitted to the developer.

---

## No Telemetry

BUS Core does **not** include:

* usage tracking
* analytics services
* telemetry
* advertising identifiers

The software does not monitor how you use it.

---

## No Accounts

BUS Core does not require:

* user accounts
* logins
* cloud services

The software can run completely offline.

---

## Local Web Interface

BUS Core runs a local web interface normally available at:

```
http://localhost:8765
```

This interface is accessible **only from your device by default**, unless you intentionally configure your system to expose it to a network.

---

## Optional Update Checks

If enabled, the software may check a public repository for new releases.

These requests do not include operational data.

Update checks can be disabled.

---

## Data Ownership

You own the data stored in BUS Core.

The developer does not host or control your database.

Because the system runs locally, the developer cannot recover lost data.

Users are responsible for maintaining backups.
