Privacy Policy

Short version: our calculators run entirely in your browser. We don't ask for your email, we don't sell data, and we collect the minimum needed to keep the site running.
What we collect
- Calculator inputs stay on your device. Everything you type into a calculator is processed locally in your browser via JavaScript. It is never sent to our servers.
- Basic server logs. Our hosting provider logs standard technical data (IP address, pages requested, timestamps) for security and reliability. We don't use it to profile visitors.
- Analytics. We use Google Analytics (GA4) to understand which tools people use, so we know what to build next. Google Analytics collects usage data such as pages visited, approximate location, device and browser type, and sets cookies to distinguish visitors. We do not use it to identify individual visitors.
- Emails you send us. If you contact us, we keep your message to respond. We don't add you to any list — there is no list.
Advertising
This site is supported by advertising. We work with Google AdSense and other third-party advertising partners to display ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies (including the DoubleClick cookie) enables it and its partners to serve ads based on your browsing. You can opt out of personalised advertising at Google Ads Settings, and opt out of many third-party vendors' cookies at aboutads.info. Ad partners may collect data such as your IP address, browser type and pages visited to measure ad performance and prevent fraud, under their own privacy policies.
What we don't do
- No accounts, no email gates, no newsletters you didn't ask for.
- We don't sell, rent, or share personal information with data brokers.
- We don't run fingerprinting scripts ourselves; advertising cookies are described above, with opt-out links.
Cookies
We don't set first-party cookies ourselves. Two services we use do: Google Analytics sets cookies to measure site usage (for example, to distinguish new and returning visitors), and our advertising partners — including Google AdSense — set cookies to serve and measure ads, as described in the Advertising section above. You can block or delete cookies in your browser settings; the calculators will still work.
Children
This site is a general-audience reference. It is not directed at children under 13, and we don't knowingly collect their information.
Your rights & contact
To ask what data we hold about you, or to request deletion, email sanaullahx51@gmail.com. We'll respond within 30 days.
Changes
We'll update the effective date above when this policy changes, and note material changes here for 30 days.
