Cookies and storage
Cookie policy
Updated 21 October 2026. The calculators work without analytics cookies or an account.
Privacy choice
The browser storage key ci-privacy-v1 remembers whether you accepted or rejected analytics for up to 180 days. It stores the choice and its expiry, not calculation amounts. The session storage key ci-analytics-rejected also remembers rejection in the current browser tab to prevent a failed storage update from restoring an old acceptance. If browser storage is unavailable, your choice may need to be made again on a later visit.
Optional Google Analytics
Google Analytics is blocked until you accept it. If accepted, cookies such as _ga and _ga_E7VR5ZY0KR can distinguish visits and support site usage statistics. Analytics cookies are configured to last up to 90 days. Advertising storage and personalisation remain disabled.
Change your choice
Use to accept or reject analytics. Rejecting disables analytics and removes accessible analytics cookies on this domain. You can also delete cookies and site storage in your browser. Calculations do not depend on accepting analytics.
