W OBD2 · last updated 15 August 2026
W OBD2 is a motorcycle dashboard that reads live data from your vehicle through a Bluetooth OBD2 adapter. It is made by one person, and it is built so that your data has no reason to leave your phone.
All of it is kept in your browser's or the app's own local storage, on the phone. None of it is transmitted anywhere.
| What | Why |
|---|---|
| Your settings: language, units, speed source, bike profile, display options | So the app behaves the same next time you open it |
| The name and address of the last Bluetooth adapter you connected to | So it can reconnect on its own instead of asking you every time |
| Learned gear ratios | So the estimated gear becomes accurate for your bike |
| Trip counters | So they survive switching the bike off |
| Results of the optional exploration scan, if you run one | So a later scan can be compared against it |
| The diagnostic ride log, if you switch it on | See below |
You can erase all of it at any time by clearing the app's storage in Android settings, or your site data if you use it in a browser.
The app can use your phone's GPS as its speed source, because many motorcycles do not report a reliable speed over OBD2. When you allow this, the app reads your position only to calculate your speed and direction of travel.
Your position is never stored and never transmitted. No coordinates are written to the diagnostic log, no route is recorded, and there is no map in this app. If you prefer, you can switch the speed source to OBD in Settings and refuse the location permission entirely; the rest of the app works normally.
On Android the app also declares that its Bluetooth scanning is never used to derive your
location, which is what the neverForLocation flag on the permission means.
Bluetooth is used for exactly one thing: talking to your OBD2 adapter. The app needs to scan in order to show you the list of nearby adapters so you can pick yours. It does not use what it sees during that scan for anything else.
This is an optional feature, switched off by default, that you turn on yourself in Settings. When it is on, the app records roughly one row per second while connected, so that a bike's behaviour can be studied afterwards. Each row contains a timestamp and vehicle data only:
It contains no location coordinates and no vehicle identification number. It stays on your phone. Nothing is uploaded.
You may choose to export it as a CSV file and send it to me by email, to help work out what a particular model of motorcycle is capable of reporting. That is entirely your decision and takes a deliberate action. If you do send one, I use it only to improve support for that model, and I treat your email as ordinary correspondence: I do not add you to any list.
Nothing automatically. I have no server collecting anything from this app, and the app makes no network requests while you use it.
If you use the web version at weathergpx.com/obd2/, the hosting provider keeps ordinary web server logs, such as IP address and the time of the request, in the same way every website does. These are not used to build any profile. The Android app carries its own files and does not load pages from the site.
If you email me, I have your email address and whatever you put in the message, for as long as I keep the correspondence.
This app is a tool for vehicle owners and is not directed at children.
Because I hold no data about you, there is nothing for me to show you, correct or delete, unless you have emailed me. In that case, ask and I will delete the correspondence.
If this policy changes, the date at the top changes with it. If a change ever meant the app started collecting something, it would be announced in the app's version history rather than quietly edited in here.
