  • No “free key generators” – Avoid websites offering free Nine license keys. These are often scams, may contain malware, or lead to account bans.
  • Lost key recovery – If you lose a manually purchased key, contact Nine Support via their official website with your order details. Keys purchased via Google Play are automatically restored when you sign in.
  • Lifetime license – Nine traditionally offers a one‑time purchase (not subscription) for the full version. Be cautious of any subscription requests.
