UK SORA Population Calculator

Who we are

Leaping Wing Ltd is the controller of the personal data collected by this calculator. You can reach us through our contact page.

What we collect

• Your name, email address and company, which you enter before using the calculator.
• The date and time you registered.

The KML/KMZ files you load and the results you calculate are processed entirely in your browser. They are not uploaded to us or stored by us. Your details are also kept in your browser's local storage, so you are not asked again on the same device.

Why we use it

• To give you access to the calculator and keep a record of who uses it. Our lawful basis is our legitimate interest in providing a free tool and understanding who it serves.
• To follow up with you by email about your SORA work and how we could help. Our lawful basis is our legitimate interest in responding to people who have used our tools. We will ask before sending you any regular marketing, and you can opt out of any contact at any time by replying to us or using our contact page.

Where it is kept and for how long

Your details are stored on our website hosting provider's servers (Hostinger), in a location that is not publicly accessible. We keep them for up to 24 months after you last use the calculator, or until you ask us to delete them. We do not sell or share your details with anyone else.

Other services the calculator uses

To draw the map and run, your browser loads map tiles from OpenStreetMap and software libraries from public content delivery networks (cdnjs, jsDelivr). These services receive your IP address as part of normal web requests, under their own privacy policies. They do not receive your name, email or company.

Your rights

You can ask to see, correct or delete your personal data, object to how we use it, or opt out of contact, by contacting us. If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office at ico.org.uk.
