Help & FAQ

Getting started

Which one do I need — Chuck or Chuck jnr?

Chuck is for high-school teachers with several classes and subject-specific marks. Chuck jnr is for junior-school (K–6) teachers with one class across every subject. They're separate apps with separate licences.

How do I install it?

Open the app from its page (Chuck · Chuck jnr), then:

  • Chrome or Edge (Windows, Mac, Chromebook): click the install icon at the right of the address bar, or the ⋮ menu → Install.
  • Safari on a Mac: File → Add to Dock.

It then opens from its own icon and works offline. You can also find this in the app under ⚙️ Settings → App & updates.

Does it work on iPads or phones?

It's designed for laptops and desktops (Windows, Mac and Chromebook). It will open on an iPad, but some features (like automatic backup folders) aren't available there.

My school laptop won't let me install apps.

Installing from the browser doesn't need administrator rights on most school laptops. If it's blocked, you can simply keep the app's page as a bookmark — it still works offline once it's been opened.

Your data

Where is my data kept? Can you see it?

Everything you enter is stored in your browser on your own computer. It's never sent to us — we can't see it, and there's no account. The website only delivers the app itself.

How do I back up?

In ⚙️ Settings → Backup & restore, choose an automatic backup folder — ideally one that syncs to OneDrive, Google Drive or iCloud. The app then saves a backup there after every change, plus a dated daily copy. In Safari, use Download backup regularly instead.

How do I move to a new computer?

On the old computer, download a backup (or use your backup folder). On the new one, open the app, activate your licence, then ⚙️ Settings → Restore from a backup.

What happens to my data if I clear my browser?

Clearing "site data" for the app removes it from that browser — which is exactly why automatic backups matter. Restore from your latest backup and you're back where you were.

Is it OK to store student information in it?

The app keeps student information on your device only, and you can add a passcode to encrypt it. As with any tool, follow your school's and system's privacy policies — see our privacy policy.

Licences & buying

What does the free trial include?

Everything you need to enter your classes, marks, roll and notes — with no time limit. A licence unlocks the dashboards, printable reports and exports, and removes the trial notice.

How do I get my licence after buying?

It's emailed to you straight after payment, with a one-click Activate link. It's also shown on the page you return to after paying.

I've lost my licence email.

Have it sent again — enter the email you bought with.

Can I use my licence on more than one computer?

Yes — a single-teacher licence is for you, on your own devices (for example a school laptop and a home computer). Please don't share it with colleagues; your name appears in the app and on printouts.

Do I pay again for updates?

No. Your licence covers every update to the version you bought. A future major new version may be offered as an optional, discounted upgrade.

What's your refund policy?

If it's not right for you, email [support@your-domain] within 30 days of purchase for a full refund — no questions asked.

Can my school pay by invoice?

Yes — see school licences to buy online or request a quote and pay by purchase order.

Still stuck?

Email [support@your-domain] — we're teachers too, and we'll get back to you.
