Cookie Policy | CalculatorDrive

What Are Cookies?

Cookies are small text files stored on your device when you visit a website. Similar technologies — such as local storage, pixels, and SDK identifiers — can serve comparable purposes.

Cookies help websites remember settings, keep you signed in, understand usage, and — where permitted — show relevant advertising that helps fund free services like CalculatorDrive.

Why We Use Cookies

We use cookies and similar technologies to:

Keep the site secure and functioning correctly
Remember your language and optional login session
Understand which calculators are useful so we can improve them
Measure traffic and diagnose performance problems
Serve and measure advertising, where you have consented or where permitted by law
Show consent choices where required (for example, through Google's consent tools)

Types of Cookies We Use

1. Strictly necessary cookies

Required for core site functions — such as security, load balancing, session management, and CSRF protection. These cannot be switched off through our site without breaking basic functionality.

2. Functional cookies

Remember choices you make — for example, your preferred language — so you do not have to set them on every visit.

3. Analytics cookies

Help us understand how visitors use CalculatorDrive — such as which pages are visited and how users navigate the site. We use this information in aggregate to improve content and performance.

4. Advertising cookies

Used by us and our advertising partners to deliver ads, limit how often you see an ad, and measure ad performance. Where required, we ask for your consent before non-essential advertising cookies are used.

Third-Party Cookies & Partners

Some cookies are placed by trusted third-party services that help us operate CalculatorDrive. These partners may collect information about your visits to this and other websites. Common categories include:

Google Tag Manager / Google Analytics — Site measurement and event tracking loaded through our tag manager container
Google AdSense / Google ad services — Advertising delivery and measurement
Google Funding Choices — Consent management for ads and certain cookies in applicable regions
Cloudflare — Performance, security, and analytics related to content delivery

We do not control all cookies set by third parties. Each partner's use of data is governed by its own privacy policy. We encourage you to review:

How Long Cookies Last

Session cookies

Deleted when you close your browser — for example, cookies tied to a single browsing session.

Persistent cookies

Remain on your device until they expire or you delete them. Duration varies by purpose — from days to several years for some analytics or advertising cookies set by third parties.

Your Choices

You have several ways to manage cookies:
