Operator review required. Reviewed 27 October 2026. This is not a legally final notice. Controller identity, contact, actual hosting and retention settings must be completed before publication. Effective date remains unconfirmed.
Cookies and local storage
Cookies are small values a browser may send with requests. Local storage stays in browser storage until cleared and is not automatically attached to requests. Similar storage must also be assessed by purpose.
The only necessary storage identified in this application’s live check is the local consent preference. Optional analytics stays off until permission. No marketing or advertising tags were identified in the application’s audited flows.
Consent and withdrawal
Accept, reject or manage optional cookies using the banner. Browsing, scrolling or closing preferences is not acceptance. You can use every calculator without permission.
Cookie settings in the footer lets you change your choice. Withdrawal disables future tracking, clears applicable first-party analytics cookies where feasible and reloads when the preference can be saved. With storage unavailable, the choice is respected in-memory for the current visit. Global Privacy Control keeps analytics off.
Inventory and review
The table below records a Chromium localhost inspection on 27 October 2026. No cookies or Google Analytics requests were seen before acceptance. After acceptance, the Google library, collection endpoint and two first-party GA cookies were observed. Production, other browsers and Google property settings must be checked before publication.
An unused sidebar component contains a seven-day sidebar_state cookie writer; it is not mounted in the audited pages and was not observed. It is not listed as active storage. No enquiry or advertising storage is claimed.
Browser controls and retention
Deleting the consent preference brings the prompt back. You can block cookies or clear site storage in your browser, but browser controls do not erase previously collected provider data. Cookie expiries and provider retention may differ.
Google Fonts makes requests without setting cookies in the observed check. Fonts are a third-party data-flow disclosure, not a reason to invent a cookie entry. New embeds, newsletters, ads or personalisation require an audit before use.
