This Privacy Policy describes how 1OnlineCalculator.com (“we,” “us,” or “our”), operated by Asher Paul and accessible at www.1onlinecalculator.com, collects, uses, and shares information when you visit our website.

By using this website, you consent to the data practices described in this policy. If you do not agree with the terms of this policy, please do not access the site.

1. Information We Collect

We do not require you to create an account or provide any personal information to use our calculators. However, certain information may be collected automatically:

• Log data: When you visit our site, our hosting provider may automatically log your IP address, browser type, referring and exit pages, and the date and time of your visit.
• Cookies: We and our advertising partners use cookies and similar tracking technologies to improve user experience and serve relevant advertisements. See the Cookies section below for full details.
• Calculator inputs: Numbers you enter into our calculators are processed locally in your browser and are not transmitted to or stored on our servers. Your financial data never leaves your device.

2. Google AdSense & Third-Party Advertising

This website uses Google AdSense to display advertisements. Google AdSense is an advertising service provided by Google LLC. When you visit our site, Google may use cookies and web beacons 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 based on your visits to our site and other sites on the internet.
• Google AdSense uses the DoubleClick cookie to serve more relevant ads across the web and to limit the number of times a particular ad is shown to you.
• You may opt out of personalised advertising by visiting Google My Ad Center or Google Ads Settings.
• You can also opt out of a third-party vendor’s use of cookies by visiting the Network Advertising Initiative opt-out page.

3. Google Analytics

We use Google Analytics to analyse how visitors use our site. Google Analytics collects information such as which pages you visit, how long you spend on each page, and how you navigated to the site. This data is aggregated and anonymised — it does not personally identify you.

Google Analytics uses cookies to collect this data. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

4. Cookies

Cookies are small text files stored on your device by your browser. We use cookies for the following purposes:

• Analytics: Google Analytics cookies help us understand how visitors interact with our site (pages visited, time on site, etc.). These cookies do not personally identify you.
• Advertising: Google AdSense places cookies to personalise the ads you see on our site and measure ad performance.
• Functionality: Some cookies may be used to remember your preferences on return visits.

You can control and manage cookies through your browser settings. Most browsers allow you to refuse cookies, delete existing cookies, or be notified when new cookies are set. Please note that disabling advertising cookies does not mean you will not see ads — you may continue to see non-personalised advertisements.
