Privacy Policy
Last updated: November 2024
In plain English
- The cost calculator runs entirely in your browser. Your mileage, MPG, fuel prices, and electricity rates are never sent to or stored on our servers.
- If you enter a postcode, it is sent to the free postcodes.io API to look up your geographic location. We do not store your postcode.
- We do not require you to create an account or provide personal information to use the calculator.
- We may use basic, privacy-respecting analytics to understand how the site is used, with no personally identifiable data collected.
- We do not sell data to third parties.
What data we collect
Calculator inputs
Your annual mileage, MPG, fuel prices, electricity rates, and other calculator inputs are processed entirely within your browser using JavaScript. These values are not transmitted to any server operated by ElectricVsPetrol.co.uk.
Postcode (optional)
If you choose to enter a UK postcode, it is sent via a secure HTTPS request to postcodes.io — a free, open-source UK postcode lookup service. This returns your geographic region (e.g. "South East") which is used to display region-appropriate pricing context. Your postcode is not stored in our databases. Please review the postcodes.io terms for their data handling.
Analytics
We may use privacy-respecting web analytics (such as Plausible Analytics or similar cookieless tools) to understand aggregate usage patterns — for example, how many visitors use the calculator and which pages are most visited. No cookies are set and no personally identifiable information is collected through analytics.
Cookies
This site does not currently use cookies for tracking or advertising purposes. We may use browser local storage to save your calculator settings between visits, purely for your convenience. No tracking cookies or third-party advertising cookies are set.
Third-party services
| Service | Purpose | Data shared |
|---|---|---|
| postcodes.io | Postcode geolocation | Postcode only, if entered |
| Google Fonts | Typography (Inter, Space Grotesk) | IP address (on font load) |
| Analytics (if enabled) | Aggregate usage statistics | No personally identifiable data |
Your rights (UK GDPR)
Since we do not collect or store personal data through the calculator, there is no personal data to access, correct, or delete.
If you have questions about how your data is handled, please contact us at privacy@electricvspetrol.co.uk.
