What we collect, what we don't, and how your data is handled.
StatClinic (statclinic.net) is a free, browser-based statistics tool suite and educational resource for medical research, operated by Auronile. This policy explains, as plainly and accurately as we can, what happens to data when you use the site.
All statistical calculations on StatClinic (t-tests, ANOVA, regression, meta-analysis, and every other tool on the site) run as JavaScript directly in your web browser. When you type in values or upload a dataset to a calculator, that data is read and processed locally on your device to produce a result. It is not transmitted to any StatClinic server, and we have no backend that receives, stores, or has access to it.
This means we do not see, collect, or have any ability to store the clinical values, patient-level data, or research datasets you enter into a calculator. Closing the browser tab or reloading the page clears that data from memory (except for the calculation history described below, which is stored only on your own device).
To let you revisit recent results, StatClinic saves a short history (the test used, a summary of the result, and the date/time) in your browser's localStorage — a storage area built into your browser that is specific to your device and is never transmitted to us or anyone else. This history is capped at your last 20 calculations and can be cleared at any time by clearing your browser's site data for statclinic.net.
StatClinic uses Google Analytics (GA4) to understand overall traffic patterns — for example, which pages are visited and roughly how many people use the site. Google Analytics uses cookies and collects information such as your approximate location (derived from IP address), browser and device type, and pages visited. It does not have access to the data you enter into a calculator, since that never leaves your browser.
You can learn more about how Google uses this data at Google's Privacy Policy, and you can opt out of Google Analytics tracking across all websites using the Google Analytics Opt-out Browser Add-on.
This site has integrated the Google AdSense platform, which involves a script in our page code that identifies our site to Google's advertising systems. As of the date on this page, StatClinic may not yet be displaying live advertisements on every page — but because the AdSense script is present, Google and its advertising partners may already set cookies or use similar technologies to serve and measure ads, both now and as advertising is enabled more broadly across the site.
Once advertisements are active, Google and its partners may use cookies to serve ads based on your prior visits to this or other websites, and may collect data as described in Google's Advertising Technologies policy and How Google uses data in advertising. Where required by applicable law (for example, for visitors in the EEA, UK, or Switzerland), we will seek your consent before serving personalized ads, and you will be able to manage your ad personalization preferences at Google's Ad Settings.
Advertising on this site, whenever and wherever it appears, is served independently of the statistical calculators — enabling or disabling ads has no effect on how your calculation data is processed, since that data never reaches a server in the first place.
| Data | Collected? |
|---|---|
| Values/datasets you enter into a calculator | No — processed locally in your browser only |
| Calculation history (test name, summary, date) | Stored only in your own browser's localStorage; never sent to us |
| Account information / registration data | No — StatClinic does not require an account |
| Anonymous traffic/usage analytics (Google Analytics) | Yes |
| Advertising cookies (Google AdSense, once ads are live) | Yes, where and when ads are served, subject to consent requirements described above |
| Information you send us directly (e.g. a contact email) | Yes — only what you choose to include in that message |
Our blog links to external resources (for example, the Cochrane Handbook, PubMed Central, and similar research organizations) for further reading. These are independent websites with their own privacy practices, and this policy does not cover them.
StatClinic is intended for medical students, clinicians, and researchers, and is not directed at children under 13. We do not knowingly collect personal information from children.
We may update this policy as the site evolves — for example, when advertising is enabled more broadly, or if new features change how data is handled. The "Last updated" date below will reflect the most recent revision.
Questions about this policy or how your data is handled can be sent to support@statclinic.net, or via our Contact Us page.
