Privacy Policy
Last updated: July 2025
Overview
This Privacy Policy explains how Smart-Calcs ("we", "us", or "our") collects, uses, and protects information when you visit smart-calcs.net (the "Service"). By using the Service, you agree to the practices described below.
Information We Collect
We do not require you to create an account or provide personal information to use our calculators. We collect anonymous usage data such as pages visited, time spent, and general location (country-level) through analytics. Some calculators store your inputs locally in your browser via localStorage — this data never leaves your device.
Cookies and Local Storage
We use localStorage to remember your calculator inputs and preferences between visits. We use cookies for analytics and to display relevant advertising. You can disable cookies in your browser settings, but some features may not function correctly.
Third-Party Advertising
We use Google AdSense to display ads on the Service. Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other internet sites.
Third-Party Privacy Policies
This Privacy Policy does not apply to advertisers or third-party websites. We advise you to consult the respective privacy policies of these third-party ad servers for more detailed information on their practices as well as for instructions about opting out of certain practices.
Children's Information
Our Service does not address anyone under the age of 13. We do not knowingly collect personal identifiable information from children under 13. If you are a parent or guardian and believe your child has provided us with information, please contact us so we can remove it.
Your Data Protection Rights
Under GDPR (EU) and CCPA (California), you have the right to access, correct, or delete your personal data. Since we do not collect personal data, most of these rights are not applicable. However, you can clear your localStorage data at any time by clearing your browser cache.
Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
