Cookie Policy

1. What are cookies?

Cookies are small text files stored on your device when you visit a website. They allow the site to recognise your device and store certain information about your preferences or past actions.

We also use similar technologies such as local storage and, where applicable, small scripts for analytics or performance monitoring.

2. Why we use cookies and similar technologies

We use cookies and similar technologies on calclk.com and associated sub-domains (the "Platform") for the following purposes:

• Strictly necessary – to provide core functionality such as security, session management, load balancing, and remembering that you have seen key notices.
• Preferences – to remember settings such as your chosen language or low-bandwidth mode.
• Analytics – to understand, in aggregate, how users find and use the Platform so that we can improve calculators, content and performance.

We may use third-party advertising cookies (for example, Google AdSense) to display and serve relevant advertisements. These cookies allow advertising partners to measure ad performance and display ads that are more relevant to your interests.

You can opt out of personalised advertising via Google Ads Settings or by using aboutads.info.

3. Types of cookies we use

3.1 Strictly necessary cookies

These cookies are essential for the Platform to work properly. Without them, some services may not function. For example:

• session identifiers used to maintain your login state (if accounts are enabled);
• security cookies used to prevent abuse or unauthorised access;
• cookies or storage flags to remember your cookie-consent choices.

Because they are essential, these cookies cannot easily be disabled without affecting basic functionality.

3.2 Preference cookies

These remember choices you make, such as:

• preferred language;
• whether you have enabled a low-bandwidth or accessibility mode;
• UI settings (for example, collapsed/expanded views).

Disabling these may reduce your experience but should not prevent basic use of calculators.

3.3 Analytics cookies / similar technologies

We may use privacy-respecting analytics tools to collect aggregated information about how the Platform is used, such as which calculators or pages are visited and how often, approximate device and browser types, and anonymised or pseudonymised usage statistics.

We configure analytics so that they do not track individual behaviour across unrelated sites and do not collect more data than necessary.

3.4 Advertising cookies

If we serve advertisements through Google AdSense or similar networks, advertising cookies may be set on your device. These cookies allow the advertising network to:

• measure ad impressions and click-through rates;
• display ads based on your visit history and interests;
• limit the number of times you see the same ad.

You can manage or disable advertising cookies through your browser settings or via the opt-out links provided in Section 2 above.

5. Local storage and similar browser technologies

Some functionality (for example, saving draft calculator inputs or dashboard figures on your device) may use local storage or similar browser-side storage instead of cookies. This data generally stays on your device and is not automatically transmitted to us unless you choose to sync or create an account.

You can typically clear local storage through your browser settings.

6. Managing your cookie and tracking preferences

You have several options to manage cookies and similar technologies:

• Browser settings – most browsers allow you to block or delete cookies and to manage site-specific permissions.
• In-Platform controls – where required by law, we display a cookie banner or settings panel that lets you accept or reject non-essential cookies (for example, analytics).
• Do Not Track / privacy signals – where technically feasible, we aim to treat recognised browser privacy signals as an opt-out from non-essential tracking.

If you block or delete cookies, some features of the Platform may not function as intended, but core calculators should still work.

7. Cookies set by third parties

We may embed content or tools from third parties (for example, video players or embedded charts). These third parties may set their own cookies, which we do not control. You should review their separate cookie or privacy policies for details.

We aim to avoid or minimise third-party tracking technologies and will review integrations regularly.

8. Updates to this Cookie Policy

We may update this Cookie Policy from time to time, for example to reflect changes in technologies, legal requirements or our use of cookies.

When we make material changes, we will update the "Last updated" date above and, where appropriate, show an updated cookie banner or notice.
