Hosting and links
The hosting provider may process IP addresses and request information to deliver and secure the website. See Cloudflare's privacy policy. Following an external link takes you to that provider, whose privacy policy applies. Future affiliate links may use the partner's tracking after you click; none are active now.
Owner and contact enquiries
This website is owned by Lexcroft.com. For website, business or privacy enquiries, use our contact form.
The contact form opens on Google Forms, an external service. The supplied form asks for your name, email and address, and includes phone number and comments fields. Information you choose to submit is sent to Google and the form owner to handle your enquiry. It is separate from our calculators. Read the notices shown on the form and Google’s privacy policy before submitting. Avoid including payment details, passwords, account credentials or other sensitive information.
We use enquiry information to review and respond to the enquiry, rather than to run your mobile account or provide personalised plan advice. No personal information is requested by the calculators.
