# Credit System

> Credit sources, consumption priority, and expiration rules

Credits are the universal currency on the Profy platform. Whether you're using AI conversations, generating images, synthesizing speech, or creating videos, all consumption is measured in credits. This page helps you understand how to earn credits, the deduction order, and expiration rules.

## Credit Sources

You can earn credits through the following methods.

<AccordionGroup>
  <Accordion title="Signup Bonus">
    After registering as a new user, the system automatically grants a signup bonus to your account. These credits are available immediately and help you quickly experience the platform's core features.

    <Tip>The exact amount of the signup bonus is configured by operations and may vary. Please refer to the actual amount credited to your account after registration.</Tip>
  </Accordion>

  <Accordion title="Subscription Plan Bonus">
    After purchasing a paid plan, the system grants you the plan's corresponding bonus credits in a lump sum. Annual plans also provide additional monthly bonus credits at each billing cycle.

    The bonus amount varies by plan. Please refer to the real-time display on the subscription page within the product for exact values.
  </Accordion>

  <Accordion title="Credit Top-Up Packs">
    You can purchase top-up packs at any time from the billing page to replenish credits on demand. Multiple denominations are available, and some include additional bonus credits.

    See [Credit Top-Up Packs](/en/documentation/billing/top-up) for details.
  </Accordion>

  <Accordion title="Referral Rewards">
    Invite friends to register using your unique referral link. When they complete the required action, both you and your friend receive credit rewards.

    See [Referral Rewards](/en/documentation/billing/referral-rewards) for details.
  </Accordion>

  <Accordion title="Gift Card Redemption">
    Earn credits by redeeming gift cards. You can purchase them from the gift card store or receive them through promotions and events.

    See [Gift Cards](/en/documentation/billing/gift-cards) for details.
  </Accordion>
</AccordionGroup>

## Consumption Priority

When you spend credits, the system deducts from different sources in a fixed priority order. Credits that are about to expire or have lower cost are consumed first, while purchased credits are used last.

<Steps>
  <Step title="Daily Bonus Credits">
    Credits from daily check-ins or event rewards are consumed first.
  </Step>

  <Step title="Signup Bonus Credits">
    The one-time bonus received upon registration.
  </Step>

  <Step title="Plan Bonus Credits">
    Bonus credits included with your subscription plan.
  </Step>

  <Step title="Referral Reward Credits">
    Credits earned from inviting friends.
  </Step>

  <Step title="Top-Up Bonus Credits">
    Additional credits bundled with top-up pack purchases.
  </Step>

  <Step title="Purchased Credits">
    Credits purchased directly through top-up packs — consumed last.
  </Step>
</Steps>

<Note>
  This deduction order means your purchased credits are always saved for last. Bonus and reward credits are consumed first.
</Note>

## Expiration Rules

Not all credits are permanent. Different sources follow different expiration policies:

| Credit Type       | Expires?          | Notes                                                          |
| ----------------- | ----------------- | -------------------------------------------------------------- |
| Signup Bonus      | Has expiration    | Unused balance is cleared after expiration                     |
| Plan Bonus        | Has expiration    | Typically tied to the subscription cycle                       |
| Referral Rewards  | Has expiration    | Expires based on the validity period set at issuance           |
| Top-Up Bonus      | Has expiration    | Bonus credits from top-up packs have an independent expiration |
| Purchased Credits | **Never expires** | Credits purchased directly through top-up packs are permanent  |

<Warning>
  Expired credits are not refundable. We recommend using them before they expire, or upgrading your plan to receive more bonus credits.
</Warning>

## Checking Your Balance

You can check your current credit balance at any time in the following locations:

* **Avatar dropdown menu**: Click your avatar in the top-right corner — your balance is displayed at the top of the menu.
* **Billing page**: Go to "Settings → Billing" to view balance details and recent consumption history.

<Tip>
  Your credit balance updates in real time. After each AI conversation or creative generation completes, the balance immediately reflects the latest deduction.

## FAQ

<AccordionGroup>
  <Accordion title="What is the relationship between credits and real money?">
    Credits are an internal consumption unit on the platform and do not have a fixed exchange rate with any currency. Different top-up packs are priced differently and may include varying bonus ratios.
  </Accordion>

  <Accordion title="What happens when my balance is insufficient?">
    When your balance is insufficient, you won't be able to initiate new AI conversations or creative generation requests. The system will prompt you to top up or upgrade your plan.
  </Accordion>

  <Accordion title="How are credits calculated for team users?">
    If you're a team member and currently using the "Team" billing subject, consumption is deducted from the team credit pool without affecting your personal credits. See [Team Billing](/en/documentation/team/team-billing) for details.
