## License scope

Every key belongs to a Nosmai Console project, platform, and application
identity. Android verifies the signed package ID, iOS verifies the bundle
identifier, and Web verifies the configured origin.

A key that succeeds in Postman can still fail inside an app if the installed
application reports a different identity or platform. Create separate keys for
different platforms and application IDs.

## MAU pricing

Nosmai Effects pricing is based on monthly active users, not camera frames, API
calls, or effects applied. Current plan prices and included features are shown
on the [Effects pricing section](https://nosmai.com/effects/#pricing).

The exact counting window, overage handling, and commercial terms for a project
are defined by the active plan or agreement. Use Nosmai Console for the current
project status instead of hard-coding plan assumptions into the app.

## What users see

![Camera output and application action for each Nosmai license state](/images/docs/license-verification-states-v1.svg)

| License state | Camera output | Host application |
| --- | --- | --- |
| `VALID` | Normal output | Continues normally |
| `UNVERIFIED` | Watermark while verification is pending or temporarily unavailable | Remains alive |
| `INVALID` | Full-frame blur and watermark | Remains alive |
| `EXPIRED` | Full-frame blur and watermark | Remains alive |

The SDK does not intentionally crash the host application for these states and
does not show a system toast. Native `3.0.4` embeds an enforcement message in
the processed output for confirmed invalid or expired states. An expired
license asks the user to contact the administrator; `MAU_LIMIT_EXCEEDED` says
that the monthly usage limit was reached; other invalid states report that
Nosmai Effects is unavailable. The host app may add its own recovery UI, but it
must not promise access while the SDK is enforcing the state. Treat license
status as production state because it can visibly change preview, recording,
and processed output.

## Trial and production readiness

Use the trial to verify the complete integration on supported physical
devices. Before release, confirm the final signed app identity, active plan,
enabled features, and billing state. Monitor license callbacks and keep support
logs that exclude the full secret key.
