Classlings keeps only what schools need to run their classes, keeps its database in London, and never sells information, shows adverts or uses pupils’ information for anything else.
For pupils
Your teacher gives you a code to sign in. Classlings keeps your name, your class, your points and your Classling so you can play and see how you’re doing. Only you, your teacher and some staff at your school can see them. If your class is trying Kit’s island, your quickest time goes on your class’s board, with your first name and the first letter of your surname, for your class to see. We never show you adverts or share your information with anyone to sell you things. If you have a question, ask your teacher.
Who we are. Classlings (formerly ClassSlate) is run by Harry Bell, a sole trader. Contact: hello@classlings.com. ICO registration number: ZC278172.
Our role. For pupils’ information, the school decides what’s used and why. The school is the controller, and Classlings works for it as a processor, following its instructions. Teachers who use Classlings with a class confirm that their school has agreed. For teachers’ own accounts, Classlings is the controller.
What we collect
| Who | What | Why |
|---|---|---|
| Teachers and school staff | Email address and password (the password is held by our sign-in provider and can’t be read by us), school, role, invites, when you joined and last signed in, and how long each tool is used each day | To run your account and your school’s shared features, keep the service secure, and plan capacity |
| Pupils: signing in | Name, class and a sign-in code. The code is kept locked (encrypted) so teachers can reprint login cards. When a pupil signs in, we note the time and the kind of browser, such as “Chrome on a Chromebook” | So each pupil can sign in to their own Classling, and teachers can see who’s logged in |
| Pupils in the Classling Cup | Points given or taken away, the reason, who gave them and when; Showdown results, wins, levels, badges, mystery boxes and their Classling’s looks | The class’s points game, and the record of points over the school year |
| Pupils in Maths Practice | Topics, answers, time taken, levels and badges | Practice, and progress views for the teacher |
| Pupils in Reading | Books set and chosen, progress, answers, reflections and messages with their teacher | Reading practice and feedback |
| Pupils trying Kit’s island | Their quickest time to pick all the flowers, and when they set it | The class’s board of quickest times, while the game is tested |
| Pupils in Break Tracker | Toilet and drink breaks, with times | Knowing who is out of the room |
| A school’s pupil list, if the school uses one | Names (including legal and preferred names), year group and a school reference number | So staff can share classes across the school |
| Anyone who uses Report a problem | Your message, your email address and account, the page you were on and your browser | To reply and fix the problem |
We don’t collect pupils’ email addresses, photos, home addresses or contact details. The register photo reader reads a photo of your register on your own computer to pick out the names; the photo is never uploaded or kept.
Why we’re allowed to use it
- Pupils’ information: we use it only on the school’s instructions, to provide Classlings to the school. The school’s own reason applies, usually its public task of educating pupils.
- Teachers’ accounts: to provide the service you signed up for (a contract with you).
- Security, fixing problems and usage figures: our legitimate interest in keeping Classlings safe and running well.
Who helps us
| Company | What it does | Where your information is |
|---|---|---|
| Supabase | The database and sign-in | London, UK (support staff in the USA and Singapore) |
| Netlify | Serves the website; teachers’ requests to the database pass through it; keeps Report a problem messages | USA, served worldwide (data bridge) |
| Resend | Sends emails: invites, confirming your email address, password resets | USA; emails sent from Ireland (data bridge) |
| Cloudflare Turnstile | Checks that sign-ins and sign-ups come from a person, not a bot | USA and worldwide (data bridge) |
| jsDelivr | Delivers the register photo reader’s text-reading tool, only when you use it | UK company, delivered worldwide (USA and EU networks) |
| Google Fonts | Fonts on a few older pages | USA and worldwide (data bridge) |
These companies see the internet address of the computer using Classlings. Where information goes outside the UK, it’s protected by the UK–US “data bridge”, which Netlify, Cloudflare, Google and Resend have signed up to, or by contract clauses approved by the UK Information Commissioner, which Supabase and Resend use. Countries in the EU are already treated by UK law as protecting information properly.
Who can see it
- A teacher sees their own classes. Pupils see only their own Classling and work, apart from Kit’s island’s class board.
- In a class trying Kit’s island, the pupils and their teacher see the class’s board: the ten quickest times to pick all the flowers, each with the pupil’s first name and the first letter of their surname.
- If a teacher shares a class with their school, other staff there can see its register, reprint its login cards and see some results, such as Maths progress. Points and Break Tracker stay with the class’s own teacher.
- Staff at a school can see the school’s staff list (email addresses and roles) and, if the school uses one, its pupil list.
- A school’s owner and leaders can see Reading for every pupil in the school.
- A pupil’s sign-in code shows their name, class, points and Classling before they sign in. Treat codes like passwords.
- Harry Bell, who runs Classlings, can reach the database to keep it working and secure. The admin page shows teachers’ email addresses, sign-in dates and usage, not pupils’ names or work.
How long we keep it
- Your account and classes: while you use Classlings. Email hello@classlings.com and we’ll delete your account and your classes, including your pupils’ points history, within 30 days.
- Accounts not used for 2 years: we email you, then delete them.
- Pupils’ sign-in records (when, and which kind of browser): deleted 90 days after the sign-in ends.
- Kit’s island’s times: deleted when the test of the game ends, or sooner with the pupil’s account.
- Report a problem messages: deleted after 12 months.
- Usage figures: deleted after 2 years.
Cookies and device storage
- Classlings sets no cookies and uses no adverts, tracking or analytics.
- Signing in keeps a sign-in token on the device, which the site needs to work. The site also remembers settings on the device, such as sounds and the class you last had open.
- Points or breaks recorded while the internet is down wait on that computer, with pupils’ names, until they can be sent.
- “Save a copy” in the points record downloads a spreadsheet of names and totals to your computer. Look after that copy as your school asks.
Your rights
You can ask to see, correct or delete your information, or object to how it’s used. For a pupil’s information, ask the school first; we’ll help the school respond. Contact hello@classlings.com. You can also complain to the Information Commissioner’s Office at ico.org.uk.
