Who we are
Super Simple Calculator is operated by Nexar Web Services, which is responsible for personal information processed through this website. Privacy questions can be sent using the route described on our contact page.
Calculator entries
Our generated calculators run in your browser. Ordinary figures entered into them are not submitted to our server or saved in an account. Please do not put sensitive personal information into free-text fields or send it when reporting an issue.
Technical information
Our hosting and security services may process an IP address, browser and device information, requested pages, referral information and security events. This is used to deliver the site, diagnose faults, prevent abuse and maintain security. Server and security logs are kept only as long as reasonably necessary for those purposes.
Cookies and local storage
Necessary local storage remembers your light or dark display preference and your cookie choice. Optional analytics or advertising storage is used only where enabled and, where the law requires it, after consent. Choose “Accept all” or “Reject optional” in the cookie notice. You can clear the choice in your browser and choose again.
Google advertising
We may use Google AdSense to fund the website. Third-party vendors, including Google, use cookies to serve ads based on a visitor's previous visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on visits to this site and/or other sites on the internet.
You can opt out of personalised advertising through Google Ads Settings. You can also learn how Google uses information from sites that use its services on Google's partner sites information page. Other advertising vendors, if introduced, will be identified here with an appropriate opt-out route.
Analytics
We may use Google Analytics to understand aggregated site use, such as popular pages, broad device type and approximate location. Analytics data helps identify errors and improve navigation. Optional analytics storage is subject to the cookie choice where consent is required.
Legal bases and sharing
Depending on the activity, processing is based on consent, our legitimate interests in operating and securing the site, or steps taken in response to an enquiry. Information may be processed by hosting, security, analytics and advertising providers that help us operate the service. We do not sell personal information. Some providers may process information outside the UK using applicable transfer safeguards.
Your rights
Depending on where you live, you may have rights to request access, correction, deletion, restriction, objection or portability, and to withdraw consent. You may also complain to the UK Information Commissioner's Office. Contact us with enough information to identify the relevant interaction, but do not send identity documents unless requested through a secure route.
External websites and changes
Other websites have their own privacy practices. We may update this policy when the site, its providers or legal requirements change; the date above shows the latest revision.
