This Privacy Policy explains what information UseCalculator.net (“we”, “us”) collects when you use this website, how it is used and the choices you have. By using the site you agree to this policy.
Your calculations stay in your browser
All calculators run entirely in your web browser. The numbers you enter — such as income, loan amounts, weight or height — are not sent to our servers and are not stored by us. When you export a schedule as CSV or PDF, the file is created on your device.
Information stored on your device
We use your browser's local storage to remember a few preferences, such as your light or dark theme and the history of the calculator on the home page. This information never leaves your device. You can clear it at any time in your browser settings or with the clear button in the history panel.
Information collected automatically
Like most websites, our hosting provider and security services automatically receive standard technical information when you visit, such as your IP address, browser type, device type, the pages you request and the time of the request. This information is used to deliver the site, keep it secure and understand how it is used. We do not use it to identify you personally.
Cookies
Cookies are small text files stored by your browser. We do not need cookies for the calculators to work. Third-party services described below, such as advertising and analytics partners, may set their own cookies or use similar technologies.
Advertising
This site is supported by advertising and may use Google AdSense or other ad networks. These third-party vendors, including Google, use cookies 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 serve ads to you based on your visits to this and other sites on the internet.
You can opt out of personalized advertising from Google by visiting Google Ads Settings, and from many other vendors at aboutads.info. Learn more about how Google uses information from sites that use its services.
Analytics
We may use analytics services, such as Google Analytics, to understand how visitors use the site, for example which calculators are most popular. These services collect information such as pages visited and time spent on the site through cookies or similar technologies. The information is aggregated and is not used to identify you.
Links to other websites
Our pages may link to other websites, and ads may lead to third-party offers. We are not responsible for the privacy practices of those websites, so please read their privacy policies.
Children's privacy
This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.
Your rights
Depending on where you live, for example in the European Economic Area, the United Kingdom or California, you may have the right to access, correct or delete personal information and to object to or limit certain processing, including personalized advertising. Because we do not store the data you enter in the calculators, most requests relate to our advertising and analytics partners, whose opt-out tools are linked above. You can also contact us with any request.
Changes to this policy
We may update this Privacy Policy from time to time. The date at the top of the page shows when it was last changed.
