Privacy policy
What happens to the information you enter and the reports you download.
Your salary details
The calculators work in your browser. They do not send the salary figures you enter to our server, and you do not need an account. A saved comparison stays in the open page until you refresh or leave.
PDF and image reports are made in your browser. They are saved wherever your browser normally puts downloads.
Visiting the website
Your browser contacts the website’s host to load pages, fonts and images. The host may record connection details such as your IP address and the time of a request. Hosting-specific retention details have not yet been published; contact us if you need this information.
Email enquiries
For website or privacy questions, email [email protected]. Your email provider handles the message, and we receive the information you send. Please do not include sensitive financial records or login details.
