Cookie Policy
Last updated October 31, 2026
Classeem doesn't run a tracking or advertising cookie stack. Below are the cookies and browser storage Classeem's own code uses, grouped by what they're for. Most appear only if you use the feature named. Services we embed or run on can set their own; see “Set by other services”.
Signing in (needed for accounts)
Keeps a My Classeem account holder signed in between visits. Only present if you create an account.
Until you log out, delete your account, or it expires.
A one-time security value set when you request a sign-in link, used to finish signing in securely in the same browser. Only present if you start signing in.
Removed once sign-in completes, or when it expires.
Classroom workspace (needed to take part; limited beta)
Keeps a student signed in to their class after joining with the class code and their own student code. It holds a signed reference to the student's class and code, not their name.
Up to 120 days, or until the student signs out on that device. A new student code from the teacher stops it working.
Lets a student who joined a live quiz keep playing as the same player.
6 hours.
When a student opens a Classeem page from a class assignment: the assignment's id and that page's address, so a finished game round, a print or a download on that page is reported to the teacher's assignment.
Cleared when you close the browser tab.
In a lesson a student opens from their class: which step they were on, so a reload or a locked phone returns to the same step.
Until your browser storage is cleared.
Features you use on this device
For signed-out visitors only: when the account invitation after a print, PDF or finished game was last shown, dismissed or clicked, so it appears at most once a visit and once a day, stays away for 14 days after "Not now" and stops after three. Never used to claim you already have an account, and nothing here is ever sent to us.
Until your browser storage is cleared (the per-tab flag: until you close the tab).
Only if you click an invitation: what you asked for (keep this setup, a class link, or a lesson with this sheet), the page it was on and, for a setup, the tool's settings only (never names, answers or typed text), so your account can finish it when you are back on that page. Not sent anywhere until you are signed in on that page; removed as soon as it is used.
Removed once used; ignored after 2 days.
Only if you press "Save as class list" in a classroom tool: the class lists you saved (list names and student names), any keep-apart / keep-together / front-seat rules, the jobs rotation week, and the last few groupings you showed or printed, so the name picker, wheel, groups, seating chart and jobs tools are ready next time. Never sent to us, never added to your account. Remove one list with "Forget list" or all of them with "Forget all lists on this device".
Until you forget the list or clear your browser storage.
Only if you press "Save result" in the Reading Fluency Check: the results you chose to keep (an optional student label, the passage, date, words correct per minute and accuracy), so you can compare checks over time. Never sent to us, never added to your account. Delete one result or all of them on the tool page.
Until you delete the results or clear your browser storage.
Only if you tick "Keep this timetable on this device" in the class timetable: its title, class name, period labels and subjects, so the Today board is ready next time. Never sent to us. Untick the box or press "Forget it" to remove it.
Until you forget it or clear your browser storage.
In games only: remembers which rounds you just played (as opaque content ids — never words, answers, or scores) so a replay doesn't repeat them. Stays in your browser and is never sent to us.
Cleared when you close the browser tab.
Daily practice in the math fact games: progress for up to six practice buddies on this device, told apart by an animal, never a name. Never sent to us.
Until every practice buddy is removed or you clear your browser storage.
On Spanish pages, after you choose: whether numbers use a decimal comma or a decimal point.
Until you change it or clear your browser storage.
In the Arabic counting-money game: the currency you picked.
Until you change it or clear your browser storage.
On the My Classeem page: the role you picked (teacher, tutor, parent or homeschool), so the page stays tailored while you look around.
Cleared when you close the browser tab.
For signed-in accounts without a role: how many times the role question was shown and whether you chose "Not now", so it stops appearing.
Until your browser storage is cleared.
For signed-in accounts: that the save invitation on that page was dismissed, so it doesn't come back in this tab.
Cleared when you close the browser tab.
Analytics
Aggregate, privacy-safe pageview and event measurement. Never receives worksheet content or account data. Not set when a visit starts on a student page, or arrives through a class link or a class assignment.
Up to 2 years, or until cleared in your browser.
When you arrive through a teacher's class link: that link's code, so the visit's opens, starts, finishes, prints and downloads count toward the link's totals (never who). It also keeps Google Analytics from loading in that tab.
Cleared when you close the browser tab.
Notes that the site you came from has already been counted in our own analytics for this visit, so it is counted once.
Cleared when you close the browser tab.
Only in the browsers of the people who run Classeem: a switch that leaves those browsers out of our own analytics.
Until switched back or cleared.
Built but switched off (not set today)
A choice about advertising tags. Classeem shows no ads and loads no ad tags, so this is not set.
Not set while the feature is off.
Teacher settings for AI photo review. AI features are switched off, so these are not set.
Not set while the feature is off.
Short sign-in steps for school learning platforms (LTI) and Google Classroom. Both connections are switched off, so these are not set.
Not set while the feature is off.
Remembered "Not now" on the teacher beta invitation. The beta is closed to new applications and the invitation is no longer shown, so this is not set any more; a choice stored earlier stays until you clear your browser storage.
Until your browser storage is cleared.
Set by other services
When a Classroom lesson shows a YouTube video (youtube-nocookie.com), YouTube may store data in the browser under Google's privacy policy. If our host, Vercel, asks a browser to pass a security check, Vercel sets its own cookie for that. A few features also write a test entry (such as classeem:probe) and remove it at once, to check that browser storage works.
What we don't do
- No third-party advertising or cross-site tracking cookies
- No fingerprinting
- Nothing you type into a worksheet, calculator, or game tool is ever stored in a cookie
Your choices
Every core Classeem tool works with cookies and storage fully blocked or cleared — an account and its sign-in cookie are opt-in. Joining a class or a live quiz needs its cookie. You can clear cookies and site storage at any time from your browser's settings. See the Privacy Policy for the full picture of what an account stores, and Account settings for email preferences and account deletion.
