To enable us to monitor the impact of the calculator and improve its operation we would like to automatically gather some basic anonymous information when you use the calculator. This information would include a random identification of your device and what functions you used. Your IP address and some basic information about your device or browser (for example; version and operating system) is also recorded when this feedback is sent. This data is completely anonymous and contains none of your inputs into the calculator (no scores or any similar data is recorded) and is held securely by Queen’s University Belfast in the United Kingdom for the purposes described above only. Consent to us gathering this data is entirely optional, makes no difference to the operation of the calculator, and can be withdrawn at any time. If you have any questions you can email n.lois@qub.ac.uk
