Register Your Licence

Tell us who holds this licence and which organisation it's for, so it can be activated.

Register your licence to start

Your key won't activate until you register it here. Enter the key together with your name and the email you'd like to use — that email becomes your sign-in for managing devices later, with no password to remember. Once you've registered, open The Grammar Index and enter the same key to unlock the full app.

Important — registration is permanent. Whoever registers this licence becomes its owner, and that cannot be undone or transferred to anyone else afterwards.
Buying on behalf of a school or team? Let the person who will look after the licence register it — they become its owner and manage the devices.

Already use the app? Registering doesn't deactivate anything — it just adds web device management. Lost your key? It's on your order confirmation, or ask whoever bought the licence. Still stuck? Email support@grammarindex.com.
