Privacy policy
StackItSmart is a fully static site with no accounts and no server-side database. This page describes, plainly, what that means for your data.
Last updated 2026-07-07.
What we don't collect
There are no user accounts, no sign-in, no saved cycles or profiles, and no forms on this site that ask for your name, email, or any other personal information. StackItSmart cannot see who you are, and does not build a profile of you.
What's stored in your browser
The site stores a small number of values in your browser’s local storage, on your device only. They are never transmitted to StackItSmart or any third party:
- Age confirmation — whether you've confirmed you're 21 or older, so the age gate doesn't reappear on every visit.
- Theme preference — whether you've chosen light or dark mode.
- Banner dismissal — whether you've closed the site announcement banner.
You can clear these at any time through your browser’s settings (clearing site data or local storage for stackitsmart.com); doing so simply resets the age gate, theme, and banner to their defaults.
Analytics
StackItSmart uses Google Analytics (GA4) to understand aggregate traffic — for example, which pages are read and roughly how visitors arrive at the site. Google Analytics sets its own cookies (typically named _ga and _ga_*) and collects information such as your approximate location (derived from IP address, which Google truncates), device and browser type, pages viewed, and session duration. This data is processed by Google under its own privacy policy.
StackItSmart does not use Google Analytics for advertising, remarketing, or cross-site ad personalization, and does not otherwise sell or share personal information with third parties. We do not run any other advertising or behavioral-tracking scripts. If that changes, this policy will be updated first to describe what is collected and why.
Interaction checker and search
The compound search and the interaction checker run entirely in your browser. The compounds you select are never sent to a server, logged, or stored anywhere outside your current browser tab.
Hosting and server logs
Like virtually any website, StackItSmart is served through a hosting provider that may record standard technical logs as part of normal operation — for example, IP address, browser type, and pages requested — for security and reliability purposes. StackItSmart does not use these logs to identify individual visitors or to build profiles.
Children's privacy
StackItSmart is age-gated to adults 21 and older and is not directed at children. We do not knowingly collect information from anyone under 18.
Third-party links
Citations on this site link to PubMed, DOI resolvers, and external publisher or journal pages. Those sites are operated independently and have their own privacy practices, which this policy does not cover.
Your choices
There are no accounts, so there is nothing to delete and no data export to request. To reset the local values described in §2, clear your browser’s site data for stackitsmart.com.
To opt out of Google Analytics specifically, you can install the Google Analytics Opt-out Browser Add-on, use your browser’s tracking-protection or cookie-blocking settings, or use an ad- and script-blocking extension.
Changes to this policy
This policy may be updated as the site evolves; the “last updated” date above reflects the most recent revision.
