What is a Player ID?
Nexum doesn't use email accounts. When you first open the app, it creates a private
Player ID (format XXXX-XXXX-XXXX-XXXX) on your device — that's your
account. No email, no password, no sign-up form.
What is my recovery code, and where do I find it?
Your recovery code is a 24-character code that lets you restore your account on a new phone. You can view it any time in the app under Profile → Settings → Account. Write it down or store it in a password manager — it's the only way to recover your progress if you lose your device.
How do I move to a new phone?
- Install Nexum on the new device.
- On the welcome screen, choose Recover Account and enter your recovery code.
- Your progress, streaks, and purchases come with you.
Free accounts can be linked on up to 2 devices; Premium supports up to 4.
I lost my recovery code and my old phone. Can you help?
Without the recovery code we usually cannot restore an account — we don't know your email, so there is nothing to verify you with. If you still have the old device, open the app there and copy the code from Settings. Otherwise contact support@languagenexum.app and we'll see what's possible.
What's free and what's Premium?
The free tier includes unlimited play — no hearts, no daily limits, no forced ads. Premium unlocks all languages, all game modes, advanced analytics, up to 4 devices, and family profiles (up to 5). Manage or cancel your subscription any time through Google Play; billing is handled by the store, not by us.
How do refunds work?
Subscriptions are billed by Google Play, so refunds follow Google Play's refund policy. If something went wrong on our side, email us and we'll help.
How do I export or delete my data?
Both are built into the app under Profile → Settings → Privacy — you can export everything we hold or delete your account entirely. You can also use the web forms: request my data · delete my account.
Which languages does Nexum support?
22 language options including Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Russian, Dutch, Polish, Swedish, Turkish, and Indonesian — some are in beta while we finish their content. Vocabulary is graded by CEFR level from A1 to C2.
Still stuck? Email support@languagenexum.app — include your Player ID (never your recovery code) so we can find your account.
