1. Introduction
This Privacy Policy explains how QuickToolkit (“we”, “us”, or “the site”) handles information when you visit our website and use any of our free online calculators. By using QuickToolkit you agree to the practices described below.
2. Information We Collect
QuickToolkit calculators run entirely in your browser. The values you enter (such as your date of birth, weight, marks, or loan amount) are processed on your own device and are not sent to or stored on our servers.
We may collect limited, non-personal information automatically, including:
- Standard web-server logs (IP address, browser type, operating system, referring URL, pages visited, and time stamps).
- Anonymous usage analytics (such as which tools are used most often) to help us improve the site.
- Cookies and similar technologies set by our advertising partners (see section 4).
3. Cookies
A cookie is a small text file stored on your device by your browser. QuickToolkit and our partners use cookies for the following purposes:
- Functional cookies – to remember basic preferences such as your chosen unit (e.g., cm vs. ft/in on the BMI calculator).
- Analytics cookies – to understand aggregate traffic patterns so we can improve the site.
- Advertising cookies – set by Google and other partners to deliver and measure ads (see section 4).
You can block or delete cookies through your browser settings at any time. Doing so may affect the display of ads but will not affect the functioning of the calculators themselves.
4. Google AdSense & Third-Party Advertising
QuickToolkit uses Google AdSense to display advertisements. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to show ads based on your visits to our site and/or other sites on the Internet.
You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of third-party vendor use of cookies for personalised advertising by visiting aboutads.info.
Third-party vendors, including Google, use cookies to serve ads based on a user's previous visits to our website. Google's use of the DoubleClick DART cookie enables it and its partners to serve ads to our users based on their visit to QuickToolkit and/or other sites on the Internet.
5. How We Use Information
We use the non-personal information collected to:
- Operate, maintain, and improve QuickToolkit.
- Monitor aggregate usage patterns and fix bugs.
- Display relevant advertising through Google AdSense.
- Protect the site from abuse, fraud, and security threats.
We do not sell, rent, or trade any information you provide.
6. Data Retention
Because calculator inputs never leave your device, there is nothing for us to retain about the calculations you perform. Server logs and analytics data are retained for a limited period needed for the purposes described above and then discarded.
7. Children's Privacy
QuickToolkit does not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will promptly remove it.
8. Changes to This Policy
We may update this Privacy Policy from time to time. The “Last updated” date at the top of the page will reflect the most recent revision. We encourage you to review this policy periodically.
