Boostline

Privacy policy

Last updated: 10 October 2026

Boostline does not collect, store or share any personal data. There are no accounts, no analytics, no advertising and no tracking. Everything the app records stays on your device.

What stays on your device

Boostline keeps these on your iPhone or iPad only:

Logs and reports can contain your car's vehicle identification number (VIN) and the data read from its engine computer. They are saved in the Files app (On My iPhone or On My iPad › Boostline). They only leave your device if you share or copy them yourself. Deleting the app deletes them.

Network connections

Your car's adapter, on your local network

Boostline connects to the diagnostic adapter plugged into your car (an MHD or bootmod3 WiFi adapter, or an ENET cable) over the local network, to read data from the car. iOS asks for permission to use the local network the first time you connect. This connection stays between your device and the adapter; nothing is sent to us or to anyone else.

BMW DME data, only when you ask for it

When you tap Download & import or Update from GitHub in Settings, Boostline downloads the data file of the open-source bmw-unified-db project from GitHub. As with any download, GitHub receives the request, including your IP address; GitHub's privacy statement applies to it. Boostline sends nothing else with the request.

Boostline makes no other internet connections.

Links

Links in the app (to this website and to the bmw-unified-db project) open in your web browser.

Data we collect

None. We have no servers that receive data from the app, and we can't see your logs, your car or how you use the app.

Children

Boostline is not directed at children and collects no data from anyone.

Changes

If this policy changes, the new version will be published on this page with a new date.
