EVMetricsOBD

Privacy Policy

Effective 4 July 2026 · Applies to the EVMetricsOBD app for iPhone, iPad and Mac

In short: EVMetricsOBD has no user accounts, no advertising, no analytics and no trackers. The diagnostic data the app reads from your vehicle is processed and stored on your device. The app's only network request sends your vehicle's VIN to a US government database to identify the make, model and year. Nothing is ever sold or shared with third parties for marketing.

1. Who we are

EVMetricsOBD is developed and published by Evmetrics Ltd (United Kingdom), the data controller for any personal data described in this policy. You can reach us at hello@evmetrics.co.uk.

2. Vehicle diagnostic data

The app communicates with your vehicle through an OBD adapter you own (Bluetooth, Wi-Fi or USB) and reads diagnostic data such as sensor readings, battery telemetry, trouble codes (DTCs), the vehicle identification number (VIN) and the odometer. This data is:

processed on your device;
stored only on your device (and in your personal iCloud, if you enable sync — see section 5);
never transmitted to Evmetrics Ltd — we operate no servers that receive app data.

3. Location

With your permission, the app uses your location while in use to record journeys (route maps, distance) and to keep logging vehicle data while your phone is locked during a drive or charging session. Location history is stored on your device as part of your journey records. It is not sent to us or to any third party. You can deny or revoke location access at any time in iOS Settings; the app works without it.

4. VIN lookup (NHTSA)

To identify your vehicle's make, model, year and powertrain, the app sends the VIN to the US National Highway Traffic Safety Administration (NHTSA) vPIC API, a public government service. The request contains only the VIN — no name, email, location or device identifier. NHTSA's handling of requests is governed by its own web policies. This is the only network request the app makes.

5. iCloud sync (optional)

If you enable iCloud sync, your Garage vehicle records, Workshop checklists, Fleet costs and journeys are stored in your private iCloud container, managed by Apple and protected by your Apple ID. Evmetrics Ltd has no access to it. Apple's handling of iCloud data is described in Apple's privacy policy.

6. Reports and exports you share

You can generate diagnostic reports (HTML) and export journeys, workshop templates, fleet records or GPX tracks as files. These may contain vehicle data such as the VIN, odometer and location history. They leave your device only when you choose to share them, and only to the destination you pick in the iOS/macOS share sheet.

7. Device permissions

Bluetooth — to connect to your OBD adapter.
Local network — to connect to Wi-Fi OBD adapters.
Location (while in use) — journey logging and background data capture, as described in section 3.

8. Data retention and deletion

Because your data lives on your device, you are in control of it. You can delete individual reports, journeys and vehicles inside the app, disable iCloud sync, or remove everything by deleting the app. There is no server-side copy for us to delete.

9. Your rights

Under the UK GDPR you have rights of access, rectification, erasure, restriction, portability and objection. Since we do not collect or hold your personal data on our systems, most requests can be fulfilled directly on your device — but if you have any question or concern, contact us at hello@evmetrics.co.uk and we will help. You also have the right to lodge a complaint with the UK Information Commissioner's Office (ICO).

10. Children

The app is not directed at children under 13 and we do not knowingly collect personal data from children.

11. Changes to this policy

If the app gains features that change how data is handled (for example online vehicle-record lookups), we will update this policy and the App Store privacy label before those features ship. The effective date at the top reflects the latest revision.
