Privacy Policy

Last updated: July 22, 2026

Overview

Dear Calculator provides free online calculators for everyday questions, planning, learning, and work. We aim to keep the calculators simple, fast, and respectful of user privacy.

Information processed by calculators

Calculations are designed to run directly in your browser where possible. Dear Calculator does not require an account to use the calculators and does not intentionally store your calculation inputs on our servers as part of normal calculator use.

Information we may collect

We may receive basic technical information such as pages visited, browser type, device type, approximate region, referring pages, and interaction events. If you contact us, we may receive the information you choose to send, such as your email address and message.

Analytics and advertising

Dear Calculator may use analytics and advertising services, including Google AdSense, to understand site usage and support the free availability of the calculators. Third-party vendors, including Google, may use cookies or similar technologies to serve ads based on a user's prior visits to Dear Calculator or other websites, measure ad performance, prevent fraud, and personalize or limit advertising where permitted.

Google uses advertising cookies to help serve ads. Users may opt out of personalized advertising through Google's ads settings. You can also learn more about how Google uses information from sites and apps that use its services at Google's public privacy resources.

Cookies

Cookies may be used for site functionality, analytics, security, and advertising. You can control cookies through your browser settings. For more detail, please review our Cookie Policy.

How information is used

Information may be used to operate the site, improve calculator quality, understand aggregate usage, protect the service from abuse, respond to messages, comply with legal obligations, and support advertising-funded access to free calculators.

Your choices

You can disable or delete cookies in your browser, use available privacy controls from advertising providers, and choose not to submit personal information through contact messages. Some site features or advertising controls may work differently if cookies are blocked.

Children's privacy

Dear Calculator is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children under 13.

We may update this Privacy Policy as the site grows, new calculators are added, or advertising and analytics tools change. The updated date above shows when the policy was last revised.
