Privacy policy

Lab Dossier is an informational website with browser-based lab tools. This site does not require an account and does not ask visitors to submit personal information to use a lab file, reference page, or tool.

Browser-local tool data

Tools on this site — like the hypothesis builder and lab report builder — run entirely in your browser. Any text typed into a tool stays on your own device and is not sent to or stored on our servers unless a future version of a specific tool says otherwise on that tool's page.

Advertising, analytics, and cookies

This site may show advertising served by Google and its partners, and may use Google Analytics to understand which pages are useful. These services can use cookies and similar technologies to serve ads based on prior visits to this and other websites, and to measure site traffic. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites on the internet.

You can opt out of personalized advertising by visiting Google's Ads Settings, or opt out of a participating vendor's use of cookies for personalized advertising by visiting www.aboutads.info/choices.

Children's privacy

This site is written for use in classrooms and by families, often with students present, but it does not knowingly collect personal information directly from children. Tools run locally in the browser and do not ask for a name, email address, or other personal details to work.

External links

Lab files and reference pages sometimes link to outside sources, like government agencies or safety organizations, for further reading. Those sites operate under their own privacy practices, which we do not control.

Changes to this policy

This policy may be updated as the site's tools or advertising setup changes. Check back here for the current version.
