Purchase Notes
1. What You Are Buying
When you purchase Mask, you are buying a one-time app license that unlocks app functionality.
2. What Is Not Included
A Mask purchase does not include:
- API call credits from any model platform
- Subscription fees for any model platform
- Token/request billing charged by third-party providers
3. Cost Structure (Important)
Your total cost typically has two parts:
- App license fee (one-time purchase)
- Model usage fees (billed by third-party providers)
4. Why Billing Is Separated
Mask is a client application and does not operate third-party model infrastructure. Because you can freely choose providers, API usage is billed by the provider you use.
5. Refund and Support Scope
- App-license-related refunds follow the official policy of your purchase channel.
- Third-party API fee refunds must be requested from the provider directly. Mask cannot process those refunds on your behalf.
6. Recommendations Before Purchase
- Check whether your target model platform is reliably accessible in your region.
- Test model quality with a small budget before long-term usage.
- Watch provider announcements for pricing, rate limit, and free-tier changes.
7. Common Misunderstandings
Misunderstanding A: Buying the app means unlimited model usage
No. Model usage always depends on your own API account quota and billing status.
Misunderstanding B: Funding a model account unlocks app features
No. Model account billing and app licensing are separate systems.
