What we collect

• Your analysis stays with you. The figures you enter are stored in your own browser only. They are not sent to our servers, and we cannot see them.
• Feedback you send us. If you submit the feedback form, we store the rating, comments and any email address you provide, so we can improve the tool and reply if you asked us to.
• Your choices. Your cookie decision and your acceptance of the Terms & Conditions are stored in your browser so you are not asked repeatedly.

Cookies and advertising

This site shows advertising (Google AdSense) to keep the tool free. Advertising cookies, and Google's measurement of ad views and clicks, are only enabled after you accept cookies in the banner. If you decline, the analysis works exactly the same — you simply won't see ads. You can change your choice at any time via "Cookie preferences" in the footer.

Google and its partners may use cookies to serve ads based on your visits to this and other sites. You can opt out of personalised advertising in Google's Ads Settings.

Retention and your rights

Feedback submissions are kept for as long as they are useful for improving the tool. You may ask us to correct or delete a feedback submission, including anything containing your email address, by contacting us through the feedback form.
