Cookie Policy

Last updated: April 22, 2026

In plain English

We set a small number of essential cookies for security and administration. Optional advertising services load only after advertising consent; the analytics preference is reserved for a future consent-aware service and currently loads no external collector.

1. What cookies we set

The list below is exhaustive for the main CalculatorZone domain. Third-party widgets (if any) may set their own cookies — follow the links in section 3 to manage those.

Cookie	Provider	Category	Duration	Purpose
__cf_bm	Cloudflare	Essential	30 minutes (rolling)	Bot-management token used by our CDN to distinguish humans from automated bots.
cf_clearance	Cloudflare	Essential	Up to 1 year	Records that your browser has passed a challenge; prevents repeated security checks.
admin-token	CalculatorZone	Essential	Session	HttpOnly + Secure session cookie set only when an administrator signs in at /admin/login. Not set for public visitors.
__gads, __gpi, IDE, NID, ANID, CONSENT	Google AdSense / DoubleClick	Advertising	Up to 2 years	Ad frequency capping, contextual/interest-based ad selection, ad measurement. Set only after you accept advertising cookies.

Essential

Strictly necessary for the site to work (CDN security, administrator sessions). Cannot be switched off.

Analytics

Reserved for a future consent-aware analytics service. No external analytics collector or analytics cookie is currently enabled.

Advertising

Optional. Google AdSense cookies are never set until you click "Accept advertising" on our cookie banner.

2. What we don't do

We do not load the optional advertising service before advertising consent, and no external analytics collector is currently configured.
We do not store calculator inputs, results, or personal financial data in cookies. All calculations run entirely in your browser.
We do not share cookie data with data brokers.

3. Managing cookies

You can change your cookie choices at any time using the control below, or by clearing cookieConsent in your browser storage (it lives in localStorage, not a cookie). You can also manage cookies at the browser level:

4. Legal basis

Under UK GDPR and the Privacy and Electronic Communications Regulations (PECR), we rely on:

Legitimate interests for essential cookies (CDN security, administrator sessions).
Your consent for analytics and advertising cookies — collected via our cookie banner and stored in your browser until you withdraw it.

You can withdraw consent at any time. Withdrawing consent does not affect the lawfulness of processing before withdrawal. You have the right to complain to the UK Information Commissioner's Office.
