Privacy Policy

SmartCalc keeps data collection to a minimum. This page explains what limited information is collected when you visit and how it is used.

Overview

SmartCalc is a collection of free online calculators. We keep data collection to a minimum: there are no user accounts, and the calculators themselves do not send your inputs to us. This policy explains what limited information is collected when you visit the site and how it is used.

Calculator Inputs

The numbers and values you enter into any calculator are processed entirely in your browser to produce the result shown on screen. They are not transmitted to our servers, saved to your account (there are no accounts), or shared with third parties. Closing or reloading the page clears them.

Information Collected Automatically

Like most websites, SmartCalc and its service providers automatically receive standard technical information when you visit, which may include:

• Your device's IP address and approximate location (typically city or region level).
• Browser type, operating system, and screen size.
• Pages visited, referring URLs, and time spent on the site.

This information is used in aggregate to understand traffic patterns and improve the site.

Cookies and Analytics

SmartCalc uses Google Analytics to measure aggregate site usage. Google Analytics sets cookies to distinguish visitors and sessions. We do not use this data to identify individual users.

You can opt out of Google Analytics with the Google Analytics Opt-out Browser Add-on, or by blocking cookies in your browser settings.

Advertising

SmartCalc displays ads through Google AdSense. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this and other websites. Third-party vendors, including Google, use cookies to serve ads based on someone's prior visits.

You can manage ad personalization in Google Ad Settings. For more information on how Google uses data from sites that use its services, see Google's Privacy & Terms. To learn more about interest-based advertising or to opt out of participating vendors, visit aboutads.info/choices or youronlinechoices.eu.

Local Storage

Some calculators or site preferences (such as your choice of measurement units) may use your browser's local storage to remember settings between visits. This data stays on your device and is not sent to us.

Third-Party Services

The site loads resources from third parties whose own privacy policies apply, including Google Fonts (web fonts), Google Analytics, and Google AdSense. We do not control how these providers process data.

Your Choices and Rights

Depending on where you live, you may have rights under laws such as the EU/UK GDPR or the California Consumer Privacy Act (CCPA), including the right to access, correct, or delete personal information and to opt out of the "sale" or "sharing" of personal information for targeted advertising.

• You can block or delete cookies through your browser settings.
• You can opt out of analytics and personalized advertising using the links above.
• You can contact us at contact@smartcalculations.app to make a privacy request.

Because SmartCalc does not maintain accounts or a customer database, most personal data associated with your visit is held by Google as described above, and requests concerning that data may need to be directed to Google.

Children's Privacy

SmartCalc is not directed to children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us and we will address it.

Data Retention and Security

We do not store your calculator inputs or maintain a personal database. Aggregate analytics data is retained by Google according to its own retention settings. While we take reasonable measures to keep the site secure, no method of transmission over the internet is completely secure.

International Visitors

SmartCalc is operated as a static website and can be accessed worldwide. Analytics and advertising data may be processed on servers located in other countries, including the United States.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes take effect when posted on this page, and the "Last updated" date below will reflect the revision.
