Privacy Introduction

Rounding Solver ("we," "us," or "our") operates the website www.roundingsolver.com (the "Site"). We respect your privacy and are committed to being transparent about how we collect, use, and share information when you visit or interact with our Site.

Our goal is to provide a comprehensive, accurate rounding calculator while keeping data collection to the minimum necessary to run and improve the service. This Privacy Policy explains what information we gather, why we gather it, and what your rights are.

By using the Site you agree to the practices described in this policy. If you do not agree, please do not use the Site.

Information Collection

We collect information in the following ways when you visit our Site or use our services:

  • Automatically collected information: When you visit the Site, certain technical data is collected automatically through cookies and analytics tools. This includes your IP address (in anonymized form), browser type and version, device type, operating system, referring URL, pages viewed, time spent on pages, and approximate geographic location (country or city level). See Cookies and Analytics below for details.
  • Voluntarily submitted information: If you use our contact form, you choose to provide your name, email address, subject, and message. We use this information only to respond to your inquiry.
  • Cookies and advertising data: Cookies set by us and by third-party advertising and analytics partners may collect information about your browsing behavior. See Cookies and Analytics and Advertising and Google AdSense for full details.

We do not require you to create an account, and we do not collect passwords, payment information, or other sensitive personal data.

Client-Side Calculator Processing

Our rounding calculator runs entirely within your web browser using JavaScript. All calculator inputs, numbers, calculations, and results are processed locally on your device. This means the numerical data you enter into the calculator is never sent to our servers.

We designed the calculator this way on purpose: privacy by design is a core principle of Rounding Solver.

Cookies and Analytics

What are cookies?

Cookies are small text files that websites place on your device (computer, phone, or tablet) when you visit them. They are widely used to make websites work more efficiently, to remember your preferences, and to provide reporting information.

Types of cookies we use

We use or may use the following categories of cookies:

  • Essential cookies: These are necessary for the Site to function properly (for example, remembering your language preference across the 19 languages we support). They cannot be switched off.
  • Preference cookies: These remember choices you make (such as your preferred rounding mode or number format) so we can provide a more personalized experience.
  • Analytics cookies: These help us understand how visitors use the Site—which pages are visited most, how long users stay, and where they come from—so we can improve our content and tools.
  • Advertising cookies: These are set by our advertising partners (including Google AdSense) to build a profile of your interests and show you relevant ads on this and other websites. See Advertising and Google AdSense for details.

Google Analytics 4

We use Google Analytics 4 (GA4), a web analytics service provided by Google LLC. GA4 uses cookies and similar technologies to collect and analyze information about how the Site is used. The data collected typically includes:

  • Your IP address (anonymized / truncated before storage)
  • Browser type and version
  • Device type and operating system
  • Pages viewed and time spent on each page
  • Approximate geographic location (country or city level)
  • Referral source (how you arrived at the Site)

This information is processed in aggregate to help us understand traffic patterns and improve the Site. Google may also use this data in accordance with its own privacy policy. You can learn more about how Google uses data from partner sites at https://policies.google.com/technologies/partner-sites.

How to control or delete cookies

Most web browsers allow you to manage cookies through their settings. You can typically:

  • View which cookies are stored and delete them individually or all at once.
  • Block third-party cookies.
  • Block cookies from specific sites.
  • Block all cookies.
  • Delete all cookies when you close your browser.

Please note that blocking or deleting cookies may affect the functionality of the Site and your experience. For instructions specific to your browser, visit your browser's help or support page.

You may also opt out of Google Analytics tracking by installing the Google Analytics Opt-Out Browser Add-on.

Advertising and Google AdSense

We use Google AdSense to display advertisements on the Site. Google AdSense is an advertising service provided by Google LLC.

  • Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this website or other websites.
  • Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this Site and/or other sites on the Internet.
  • Advertising cookies may be used to provide personalized advertising tailored to your interests, or to serve non-personalized ads based on the content of the page you are viewing.

Your choices:

  • You may opt out of personalized advertising by Google by visiting Google Ads Settings.
  • You may opt out of third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info.

For more information on how Google collects and processes data, please visit How Google uses data when you use our partners' sites or apps.

Please note that we do not control the cookies set by third-party advertisers and are not responsible for their privacy practices. We encourage you to review the privacy policies of any third-party ad networks.

If you are visiting from the European Economic Area (EEA), the United Kingdom, or Switzerland, we display a cookie consent banner when you first arrive on the Site. This banner asks for your consent before we set any non-essential cookies, including those used for analytics and personalized advertising.

  • You may choose to accept or decline specific categories of cookies.
  • If you decline personalized advertising cookies, you will still see ads, but they will not be tailored to your interests.
  • You can withdraw your consent at any time by clearing your cookies and revisiting the Site, or by adjusting your preferences through the cookie consent banner when it reappears.

We rely on your consent as the legal basis for processing data through non-essential cookies in these regions, in accordance with the General Data Protection Regulation (GDPR) and related laws.

Contact Information

If you contact us via our contact form or by email at roundingsolver@gmail.com, the information you voluntarily submit—your name, email address, subject, and message—will be used solely to respond to your inquiry or feedback.

We do not use contact form submissions for marketing purposes, and we do not add your email address to any mailing list.

Data Sharing

We do not sell your personal information to any third party.

However, our advertising and analytics partners—including Google (through Google AdSense and Google Analytics 4)—may collect data through cookies and similar technologies as described in the Cookies and Analytics and Advertising and Google AdSense sections above. This data collection is governed by the privacy policies of those partners.

We may also share limited information with trusted service providers who help us operate the Site (for example, our hosting provider or contact form processor), provided they agree to keep the information confidential and use it only to provide services on our behalf.

We may disclose information if required to do so by law or in response to a valid legal request (for example, a court order or government investigation).
