Information processed

What the site may process

The generator may process the options you select on the page, such as scenario, region flavour, number of samples, and whether mild real-world messiness is enabled. These options are used to create synthetic output in the browser.

Hosting services may process standard technical logs such as IP address, browser details, requested URL, and timestamp. Google AdSense and consent-management services may also process cookies or similar technical information for advertising, measurement, and consent choices.

Advertising and cookies

Google AdSense advertising

Health Data Tools uses Google AdSense to display advertising. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.

Google's use of advertising cookies enables Google and its partners to serve ads based on visits to this site and other sites on the Internet. Depending on location and applicable consent choices, ads may be personalized, non-personalized, or otherwise limited.

Users can manage personalized advertising through Google Ads Settings. The generator does not intentionally send generated output or text entered into the browser-based tools to Google AdSense as an advertising parameter.

Your responsibility

Use synthetic data only

Users are responsible for ensuring they do not paste, upload, encode, or share real patient data through the tool. If real patient data is entered into a public web tool, URL, analytics event, support message, or advertising parameter, it may create privacy and compliance risks.
