Cookie Policy

Last updated: August 2026

This Cookie Policy explains how CalcLumen uses cookies and similar technologies, and how you can control them. It should be read together with our Privacy Policy.

What cookies are

Cookies are small text files that a website stores in your browser. They let a site remember information between visits, such as your preferences, and help site owners and advertisers understand how a site is used. Some technologies, like localStorage, do a similar job of storing data in your browser without being cookies in the strict sense.

Categories of cookies we use

• Essential. These are needed for the site to function and to remember basic choices, such as whether you have responded to our cookie notice. The site cannot work properly without them.
• Analytics. These help us understand which pages are popular and how the site performs, so we can improve it. They collect aggregate usage information.
• Advertising. These are set by our advertising partner to display ads and, where permitted, to make them more relevant to you and to measure ad performance.

What CalcLumen stores itself

CalcLumenitself does not set advertising or tracking cookies. To remember small preferences such as your favorite calculators, we store a little data in your browser’s localStorage. This is not a cookie, it never leaves your device, and it is not used to track you. You can clear it at any time from your browser settings.

Google AdSense and analytics cookies

We use Google AdSense to display ads. Google and its partners set cookies to serve and measure ads, and in some cases to personalize them based on your browsing. We may also use analytics services that set cookies or similar identifiers to measure traffic. These third parties process data under their own policies.

How to manage or disable cookies

You are in control of cookies. You can:

• Change your choice on our cookie notice, or use your browser settings to block or delete cookies. All major browsers (Chrome, Firefox, Safari, Edge) let you manage cookies in their privacy settings.
• Opt out of personalized advertising through Google Ads Settings and aboutads.info.
• Note that blocking essential cookies may affect how parts of the site work.

Consent

When you first visit CalcLumen, we show a cookie notice so you can accept all cookies or reject non-essential ones. Your choice is remembered on your device. You can change it later by clearing your browser storage, which will make the notice appear again.
