Privacy Policy

EV Range Tracker ("we", "us", "our") lets you record real-world test journeys for your electric vehicle and compare the result against its official WLTP range. This policy explains what personal data we collect through the website and Android app, why, and what rights you have over it.

You can use the Android app fully without creating an account — in that case your vehicles and journeys stay stored locally on your phone and are never sent to our servers. The rest of this policy describes what happens if and when you choose to create an account, for example to back up your data or unlock Enhanced Analysis.

If you have any question about this policy or how your data is handled, contact us at info@evrangetracker.net.

None of the information below leaves your device unless you create an account — without one, it's stored only in the app's local database on your phone.

Account information — your email address, a securely hashed password (we never store your actual password), and an optional display name.

Vehicle information — registration plate, make, model, year, colour, fuel type, and (for EVs) the WLTP range and kerb weight used for scoring. If you look up a UK or Dutch registration plate, we send it to the relevant government vehicle registry to fetch these details. You may also upload a photo of your vehicle.

Journey information — when you record a test journey, we store the start and end odometer reading, battery percentage, timestamps, any notes you add, and, if you use live GPS tracking, the route itself as a series of location points. We also look up the outside temperature and elevation for your route to calculate your Performance Score.

Dashboard and number-plate photos — if you photograph your car's dashboard (to auto-fill odometer/battery readings) or its number plate, that photo is sent to an image-recognition service to read the values off it. We keep a copy for up to 30 days for quality-assurance purposes (checking and improving the accuracy of that scan), then it's automatically deleted — it is not permanently stored on our servers.

Technical and error data — if the app or website encounters an error, a crash report (which can include device information and, occasionally, an IP address) is sent to our own self-hosted error-tracking system so we can fix the problem.

If you choose to create an account, we use the information you provide to perform the contract between you and us: managing your account, storing your vehicles and journeys, calculating your WLTP Performance Score, and keeping the app working reliably. Without an account, this data is never sent to our servers in the first place, so no server-side processing happens at all. We don't use your data for advertising, and we don't sell it to anyone.

We share the minimum necessary data with the following services in order to provide the app's features:

• DVLA / RDW (UK and Dutch government vehicle registries) — to look up your vehicle's details from its registration plate.
• Google Cloud Vision — to read odometer/battery values from a dashboard photo you choose to upload.
• Visual Crossing — to look up historical weather for your journey's time and location.
• Open-Meteo / Open-Elevation — to look up elevation data along your route.
• Resend — to send account verification and password reset emails, if you request one.
• Google Analytics — only if you accept our cookie banner, to help us understand how visitors use the site. You can decline this, or change your mind later, at any time via "Cookie preferences" in the footer.

Some of these services are based outside the UK/EU (primarily the United States). Where that's the case, they operate under their own data protection agreements (such as Standard Contractual Clauses) that require them to protect your data to a comparable standard.

Our error-tracking system is self-hosted on our own infrastructure — it is not a third party and your data never leaves our servers through it.

We keep your account, vehicle, and journey data for as long as your account is active, so you can review your history at any time. If you delete your account (see below), your vehicles and journeys are permanently and immediately deleted along with it. Dashboard and number-plate photos are kept for up to 30 days for quality-assurance purposes, then automatically deleted, regardless of whether your account is still active. Crash/error reports are kept for a limited period purely for debugging and aren't linked back to your identity once your account is removed.

Under UK GDPR, you have the right to:

• Access and portability — download a complete copy of your data at any time from Preferences → Export my data.
• Erasure — permanently delete your account and everything in it, either in the Android app (Settings → Delete account) or on the website (Preferences → Delete my account). This takes effect immediately and can't be undone. Step-by-step instructions.
• Rectification — correct any inaccurate vehicle or journey details directly in the app or portal at any time.
• Object or restrict — contact us if you want us to stop or limit a particular use of your data.

If you're unhappy with how we've handled your data, you can also complain to the UK's data protection regulator, the Information Commissioner's Office (ICO).

EV Range Tracker isn't directed at children, and we don't knowingly collect personal data from anyone under 16.

We use strictly necessary cookies/local storage to keep you signed in — these don't require consent. We also use Google Analytics to understand how visitors use the site, but only after you accept the cookie banner shown on your first visit; if you decline, no analytics cookies are set. You can change your choice at any time via "Cookie preferences" in the footer.

All traffic to our website and app is encrypted in transit (HTTPS). Passwords are hashed, never stored in plain text. Administrative access to user data is logged and audited internally.

If we make a significant change to how we handle your data, we'll update the date at the top of this page. We encourage you to check back occasionally.
