Privacy Policy

Who we are
CalculatorsOnline is a collection of free browser-based calculators operated by the CalculatorsOnline Editorial Team. This policy explains what information the site handles and the choices you have. Questions can be sent through the feedback form on the Contact page.
Calculator inputs and results
Calculations run in your browser. The values you enter and the results you get are not sent to a calculation server and are not stored by this website. A link you share contains the page address only, never your entered values.
Information saved on your device
The site can save your theme, preferred currency and number format, favorite calculators and recently used calculators in your browser's localStorage. It does not save calculation inputs or results. You can remove this data at any time with your browser's site-data controls.
Cookies and advertising
The site itself does not set tracking cookies. When advertising is enabled, ads may be served by Google AdSense. Google and its advertising partners use cookies and similar identifiers to serve ads, including ads based on your prior visits to this and other websites, and to measure ad performance and prevent fraud.
You can opt out of personalised advertising from Google at adssettings.google.com, and learn more about how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites. You can also opt out of many third-party vendors' personalised advertising at aboutads.info or, in Europe, youronlinechoices.com.
Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent through a consent management platform before personalised advertising cookies are used. You can change that choice at any time through the privacy settings control shown by that platform.
Analytics and server logs
This site does not currently run an analytics service. Like most web servers, the hosting provider may record technical information such as IP address, browser type, requested page and time of request in standard server logs, used to operate and secure the service. If an analytics service is added in future, this policy will be updated first.
Your rights
Depending on where you live, you may have rights to access, correct or delete personal information, to object to or restrict certain processing, and to withdraw consent. California residents have the right to know, delete and opt out of the sale or sharing of personal information. We do not sell personal information. To exercise a right, contact us using the details above; for personalised advertising choices, use the Google controls listed in the advertising section.
Children
The calculators are general-purpose tools and are not directed at children under 13 (or under 16 where local law requires). We do not knowingly collect personal information from children.
Third-party links
Pages may link to other websites. We are not responsible for their content or privacy practices; review their policies before sharing information.
Changes to this policy
We may update this policy as the site changes, for example when advertising or analytics services are added. The date at the top shows the latest revision.
