Privacy Policy

Last updated: August 28, 2026

Discount Calculator ("we," "us," or "our") operates onlinediscountcalculator.com (the "Site"). This Privacy Policy explains what information we collect when you use the Site, how it's used, and the choices available to you. By using the Site, you agree to the collection and use of information in accordance with this policy.

Calculator Data

The discount calculator runs entirely in your browser. Any prices, percentages, or amounts you enter are processed locally on your device and are never transmitted to, or stored on, our servers. We have no record of what you calculate.

Information We Collect

Beyond calculator inputs, we collect information in two limited ways:

• Log data. Like most websites, our hosting provider automatically records standard technical details for every visit — such as IP address, browser type, device type, referring page, pages viewed, and the date and time of access. This data is used only for security, troubleshooting, and understanding aggregate traffic, and is not linked to your calculator activity.
• Analytics and advertising data. Third-party services described below (Google Analytics and Google AdSense) may collect additional data via cookies, as explained in their respective sections.

We do not require an account to use the Site, and we do not knowingly collect names, email addresses, or payment information unless you voluntarily provide them — for example, by emailing us through our Contact page.

Cookies and Local Storage

We use your browser's local storage — not a cookie — to remember your light/dark theme preference. This stays on your device, is never sent to us, and can be cleared at any time through your browser settings.

Separately, the third-party services below use cookies to enable analytics and advertising. Most browsers let you block or delete cookies, or browse in private mode, though doing so may affect how ads and analytics behave (it will not affect the calculator itself, which needs no cookies to work).

Google Analytics

We use Google Analytics to understand how visitors use the Site — for example, which pages are popular and how people arrive here — so we can improve it. Google Analytics uses cookies and similar technologies to collect information such as your approximate location, device and browser type, and on-site behavior. This data is aggregated and does not identify you personally. You can learn more about how Google collects and processes this data at How Google uses information from sites that use our services, and you can opt out of Google Analytics tracking across all websites using the Google Analytics Opt-out Browser Add-on.

Google AdSense & Advertising

We may display advertisements served by Google AdSense to support the cost of running the Site. Google, as a third-party vendor, uses cookies (including the DoubleClick DART cookie) to serve ads based on your prior visits to this Site and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this Site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info. For more detail on how Google uses data when you use partner sites or apps, see Google's Advertising Policy.

Third-Party Links

The Site may contain links to other websites, including retailer or coupon sites referenced in examples. We are not responsible for the content or privacy practices of any third-party site. We encourage you to review the privacy policy of any site you visit.

Children's Privacy

The Site is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can remove it.

Your Rights and Choices

Depending on where you live, you may have rights under laws such as the GDPR or the CCPA to access, correct, or delete personal information we hold about you, or to object to certain processing. Because we do not maintain accounts or store calculator inputs, we generally hold very little personal data tied to individual visitors — most of what exists sits with our analytics and advertising providers, and can be managed through the opt-out links above. For any request related to this Site, reach out via our Contact page.

Data Security

We take reasonable technical measures to protect the limited data we handle, including serving the Site exclusively over HTTPS. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. The "Last updated" date at the top of this page reflects the most recent revision. We encourage you to review this page periodically.
