Privacy policy

The tools

The figures you type into our tools are worked out in your own browser. They are not sent to us or stored.

Deadline reminders

If you sign up for reminders, we store your email address and which reminders you asked for. We use it only to send those reminders. You can unsubscribe at any time using the link in any email, or by contacting us, and we will delete your details.

Cookies and adverts

We may show adverts from Google AdSense, which uses cookies to show relevant ads and measure them. Where the law requires it, we ask for your consent first. You can manage Google ad personalisation at adssettings.google.com.

Analytics

We may use privacy-friendly analytics to count visits. This does not identify you personally.

Contact form

If you use our contact form, we store your name, email address and message so we can reply. We delete them once your query is dealt with, unless we need to keep them to fix an error on the site.

Your rights

Under UK GDPR you can ask to see, correct or delete the data we hold about you. Contact us and we’ll respond within one month. You can also complain to the Information Commissioner’s Office.
