EV Subs UK is a free, enthusiast-built tool for EV drivers in the UK. We are committed to handling your data with transparency and respect. This policy explains precisely what information is stored, how it is stored, and why.

The short version: we do not collect, transmit, or store any personally identifiable information. Everything that makes the calculator work is kept locally in your own browser.

We use browser cookies solely to remember the values you enter into the calculator's input fields between visits. This means when you return to the tool, your vehicle efficiency, PAYG rate, and other preferences are already populated and ready to use — saving you from re-entering them each time.

The following calculator inputs may be saved:

• Vehicle efficiency (miles per kWh)
• Your average PAYG charging rate (p/kWh)
• Trip distance and other calculation preferences
• Your light/dark mode display preference

These cookies are stored locally on your device only. They are never shared with any third party.

We do not collect, store, or process any of the following:

• Your name, email address, or any contact details
• Your location or IP address
• Your vehicle registration, make, or model
• Any payment or financial information
• Any data that could be used to identify you personally

This site uses Google Analytics to collect anonymous, aggregated usage statistics — for example, how many visitors the site receives and which pages are most popular. This data contains no personally identifiable information and is used solely to understand how the tool is being used so we can improve it.

Google Analytics may set its own cookies in accordance with Google's Privacy Policy. You can opt out of Google Analytics tracking using the Google Analytics Opt-out Browser Add-on.

This site displays adverts served by Google AdSense with a view to recouping hosting costs. Google may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising by visiting Google's Ad Settings.

You can clear all cookies set by this site at any time using the Reset All option in the settings menu on the calculator page — or by clearing your browser's cookies and site data through your browser settings.

Clearing the calculator cookies will simply mean your input values are no longer pre-loaded on your next visit — there are no other consequences.

If you have any questions about this privacy policy or how your data is handled, please get in touch and we'll be happy to help.
