Billing tab, with your plan, usage limits, and credit packs

**1. Open Account → Billing**

Sign in and open the **Billing** tab.

**2. Read your plan and usage**

Billing shows the current plan and how close you are to word, collection, pack, and credit limits. Compare tiers in [Plans and limits](/help/account/plans-and-limits.md).

**3. Upgrade, manage, or cancel**

Free accounts can upgrade to Learner or Courses. Paid accounts use **Manage Billing** for the Stripe portal, or cancel at period end. See [Upgrade, downgrade, or switch plans](/help/account/change-your-plan.md).

**4. AI credits**

**1 AI credit covers one delivered AI prompt.** Monthly included credits reset each month and do not roll over. Purchased credits do not expire. See [How credits work](/help/account/how-credits-work.md) and [Which games use AI credits](/help/using-the-app/which-games-use-ai-credits.md).

> [!NOTE]

> Stripe handles checkout, payment methods, invoices, and cancellation. Vocab Monster does not store full card numbers or CVCs.
