Privacy policy

Still In My System ("we," "us," "this site") is a free calculator. We do not require an account, and we do not ask for your name, email address, or any health information to use the calculator. Everything you type into the calculator — the substance, amount, date, and time — is processed in your browser to draw the chart and table; we do not store it on a server or attach it to your identity.

Cookies and advertising

This site uses Google AdSense to display ads, and Google Analytics to understand which pages people visit. Both services may set cookies or use similar technologies in your browser, and Google may use this data, together with data from other sites you visit, to personalize the ads you see. You can view and manage your ad personalization settings, and you can read more about how Google uses information from sites that use its services. When you first visit, a banner asks you to accept or decline analytics and ad cookies; declining keeps Google Analytics and AdSense storage disabled in your browser. We also use Vercel Analytics, a privacy-focused, cookieless page-view tool, and we set one small functional cookie ("NEXT_LOCALE") to remember your chosen language between visits. adssettings.google.com / policies.google.com/technologies/partner-sites

What we don't do

We don't sell personal data. We don't ask for your name, email, or any account details to use the calculator, and there is no password or account to be breached. The analytics and advertising cookies described above are the only data collection on this site, and you can decline them from the cookie banner at any time. If that ever changes — for example, if we add an optional newsletter — we will update this page first and describe exactly what is collected and why.
