Privacy Policy
Last updated October 3, 2026
This policy explains what CalcSolverPro, operated by Hindustan Prime, collects when you use the site.
What stays on your device
Everything you type into a calculator is processed in your browser and is not sent to our servers. We store one item in your browser’s local storage: your light/dark theme choice. It never leaves your device.
What we do not collect
- We do not have accounts, logins or sign-up forms.
- We do not ask for names, ages or any personal details to use a calculator.
- We do not knowingly collect information from children.
Server logs
Like any website, our hosting infrastructure may record standard request data — IP address, time, requested page, browser type — in server logs for security and reliability. These logs are not used to build profiles of individual visitors.
Analytics
We use Google Analytics 4 to understand, in aggregate, which pages are visited and how the site performs. It may set cookies and receives standard technical data such as pages viewed, approximate location derived from the IP address, browser and device type. We do not send what you type into a calculator, and we do not enable Google signals or advertising personalisation features.
For visitors in the European Economic Area, the United Kingdom and Switzerland, analytics storage is switched off by default under Google Consent Mode. You can also block analytics with your browser settings, or a tracking-protection extension. Google’s own policy is at policies.google.com/technologies/partner-sites.
Advertising
The site currently shows no advertising. If that changes, this page will be updated first to name the provider, what is collected and how to opt out.
If you email us, we use your address and message only to reply and to fix any problem you report.
