LabPages publishes science results pages, often for school classes. We measure how the site is used for one purpose: to make LabPages work better for the people who read and write these pages. That means knowing which pages and features are used, how quickly pages load on the devices people have, and where things go wrong.

What we never do

• No advertising. Nothing collected here is used to show anyone ads, to target ads, or to build an advertising profile. We do not sell or rent data, and we turn advertising features off in everything we send to Google (see below).
• No profiles of students. Readers are only ever counted, and the counts cannot be tied to a person. Students and others who sign in to view a page shared with them are never sent to Google.
• No cookies or browser storage for measurement, and no Google code runs in the pages.
• Nothing you type is recorded. We count that the search box or the sample picker was used, never what was searched for or chosen. The query part of the address is never sent.

Readers of a page

When someone opens a published page, these are counted per page and per day:

• Views, and whether the reader stayed engaged for at least 10 seconds, with time on the page in broad bands.
• Which tabs of the page are opened, which downloads (CSV, image) are used, and how often search and the sample picker are used.
• How long the page took to be ready, in bands (within 1, 2, 4, 8, 16 or 30 seconds, or longer).
• The kind of device, judged only from the screen width (phone, tablet or desktop), and the browser family (for example Chrome or Safari).
• How many script errors happened, by kind (at most five per view). Never the error text.
• The country, worked out by our network provider (Cloudflare) from the connection. Never the city or anything finer.
• The website that linked to the page, by domain name only (for example classroom.google.com).

No IP address is stored. To tell visits apart for one day, the server mixes the connection address, the browser type and the page with a random key that is kept only in memory and replaced every night at midnight UTC. Nothing links a reader's visits across days or across pages.

The people who manage a page (its owner, collaborators and admins) are not counted when they look at it. Only daily totals are kept, and only for 13 months.

Teachers and admins

When you use LabPages to make and manage pages (on this site, through Claude, or with an upload key), each action is written to an audit log: what was done, when, by which account, to which page, and whether it worked. Admins can read it, and it is kept for 24 months.

To understand how the tools are used, a summary of each action goes to Google Analytics: only the kind of action (for example "publish" or "share link created"), where it came from (web, Claude or the upload key), whether it worked, and your role. It is sent under a stable random code made from your account by a secret key on our server, so the same author can be followed over time, but Google never receives your name, username, email, page titles or anything you wrote. Students and other viewers are never sent.

Google Analytics

Forwarding to Google Analytics is on for this site. Everything goes from our server to Google's; nothing from Google runs in your browser.

• Readers: when a page's author has analytics on, the counts above are sent as events with the page address, title and version, plus a random daily number that cannot identify anyone.
• Authors: the action summaries described above.
• Every message tells Google that consent for advertising use and ad personalization is denied. No IP address, user id, browser string or free text is sent.
• Pages for school classes are never sent to Google, and neither is anyone who is signed in only to view a page.

Your choice

If your browser sends Global Privacy Control or Do Not Track, nothing about your visit is sent to Google and no daily visitor number is made for you. The page still adds one to its plain counts. Page authors can turn analytics off for any page, and the site admin can turn Google Analytics off for the whole site.

Who can see the numbers

A page's owner, its collaborators and the site admins see that page's counts. Admins also see site-wide totals. No one, including us, can see what a particular reader did.
