Privacy policy

Your names stay on your computer

Random Group Generator splits a list of names into random groups on your own device: paste the names, choose how many teams or how many people per team, add keep-together or keep-apart rules, and copy, print or save the teams as CSV. That single job is everything the extension does, and all of it happens inside your browser. Nothing you type is uploaded — there is no server of ours for it to go to, and there is no account to create.

What stays on your device

  • The names you paste. They are the input of the split — often a class list. Unlike a one-shot tool, this extension keeps that list so you can come back to it: the names you are working with, and the lists you save, are written to the browser's own extension storage on this device. They are never uploaded.
  • The lists you save. Up to 50 saved lists live in that storage — for each one its name, the names on it, who is marked absent, and when it was created and last changed. They are yours, on this device, and they go nowhere else.
  • The teams on screen. Group results are computed in the open tab from your list and a seed every time you split. The finished teams themselves are not stored; the names, the split rule, the keep-together / keep-apart / pin constraints, the seed and the splitter version are, which is what lets the same split be redrawn.
  • What you copy or print. The teams are copied to the clipboard, printed, or written as a CSV on your own disk, on your click. None of that passes through anything of ours.

What the extension stores

The extension keeps two entries in the browser's own extension storage, on this device. Neither one ever leaves your device, because there is no server of ours for it to go to.

  • randomGroupGenerator.v1 — your lists, the current split, and your controls. This is the one object the extension writes. It holds the saved lists under the fields named above, the current state (names, absent names, the rule, the constraints, the seed and the splitter version), the controls you last used (cards / tables / columns, projector, leftover strategy, last rule), and a count of how many times you have exported. The team cards themselves are not in this object.
  • randomGroupGeneratorRatePrompt — whether we have already asked you to rate the extension: up to three timestamps of when the short rating line was shown, and, if you answered it or waved it away, the fact that you did. That record is the only reason the line can stop: it asks at most three times in a month, and never again once you have answered. It holds nothing about you or your lists.

Those two entries are everything the extension stores. There is no e-mail and no identifier of you or of your computer in either one. The names on a list are personal data of the people you grouped — they stay on this device, they are never synced, and if you would rather they did not stay, delete the list. The extension refuses a 51st saved list rather than dropping an older one. To delete everything, remove the extension: uninstalling deletes everything it stored.

The only pages this extension opens

  • The welcome page you see after installing is part of the extension itself. It is not a website, it carries no analytics and no counters of any kind, and nothing about your files reaches it.
  • An optional feedback form on removal. When you remove the extension, Chrome may open a short form in a new tab, if one has been set up for this version. Answering is entirely optional. The address carries no parameters and nothing from your work — no file names, no page counts, no settings. The form is a Google Form, hosted by Google LLC under Google's own privacy policy; we receive only what you choose to type into it.
  • The rating line inside the extension. After a finished job the extension may show a short row of five stars. Nothing opens until you click one, and a click never attaches anything from your work to the address. One, two or three stars open a private Google Form in a new tab, so you can tell us what went wrong — the same kind of form as above, hosted by Google LLC under Google's own privacy policy, and we receive only what you choose to type into it. Four or five stars open this extension's own reviews page in the Chrome Web Store, so you can leave a public review there; that page exists only once the extension is listed, and until then a click there opens nothing and the line tells you so.

Those are the only pages the extension opens, and the only route by which anything can reach anyone other than you.

Legal bases

Where the GDPR or UK GDPR applies, we handle data on the basis of your consent and to perform the feature you asked for — the names you paste is read only in order to split the teams you asked for, because that is the job you started. You can withdraw consent at any time by stopping the job or removing the extension.

Retention and deletion

  • The names you are working with: they stay in extension storage on this device until you replace them, clear them, or remove the extension. This is deliberate — it is what lets you close the tab and come back to the same list. They live inside randomGroupGenerator.v1.
  • Saved lists: until you delete them or remove the extension. The list holds at most 50; a further save is refused, and existing lists stay.
  • The teams on screen: they live only in the open tab and are recomputed from the stored names and seed each time.
  • The remembered controls (view, projector, leftover, last rule): until you change them or remove the extension. They live inside the same randomGroupGenerator.v1 object.
  • The rating record (randomGroupGeneratorRatePrompt): until you remove the extension. Answering the rating line or waving it away does not erase the record — that is what keeps the line from coming back.
  • CSV files you saved: yours, on your own disk, for as long as you keep them.
  • On our side: nothing. We never receive any of it.

Your rights

Depending on where you live, you have rights over your personal data:

  • GDPR / UK GDPR: access, rectification, erasure, restriction, portability, objection, withdrawing consent, and lodging a complaint with a supervisory authority (such as the ICO).
  • CCPA / CPRA (California): to know, access, delete and correct your data, and not to be discriminated against for exercising those rights. We do not sell or share your personal information.

Because everything stays on your own computer, you can exercise most of these yourself: your files are in front of you, your settings are the controls you last used, and removing the extension erases everything it stored. If you would still like to make a request or ask a question, write to us at the address below and we will answer.

Security

Your files are handled inside your browser by the extension's own code, in the same browser process as the page you are looking at. They are not sent to us, and there are no third-party processors: no cloud service, no analytics provider and no error-reporting service receives any part of them. Everything the extension needs to split the names and render the page is packaged inside the extension itself, so no code is fetched from the internet while it runs. Your files are protected by your own device and browser profile, the same way the rest of your documents are.

Children

Random Group Generator is intended for users 13 and older. We do not knowingly collect personal data from children.

What we do not do

  • No accounts, no sign-up, no subscription.
  • No advertising and no ad networks.
  • No analytics, no tracking, no profiles.
  • No history of the files you have processed.
  • We do not sell or share your data. We never receive it in the first place.
  • All features in this version are free; this extension does not offer purchases.

Limited Use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Changes to this policy

This policy takes effect on 3 September 2026. What changed: this is the first published version of this policy, written for the first release of the extension. If it changes, we will update the date at the bottom of this page, and the current version always lives here.
