## Additional Information

### License Types

#### Time-Based License

A flexible license that provides a **pool of days** that you can allocate to any number of devices.\
You decide how to distribute the days across all your devices.

**Example:**\
A 30-day license can be split into 10 days for 3 different devices,\
or all 30 days can be applied to a single device.

#### Device-Based License

This is a lifetime license that allows access for a specific number of devices.\
Instead of counting days, this license counts the **number of devices** that can use it.

Commonly used for permanent device slots or lifetime subscriptions.

**Special note:**\
Device-based licenses with the **"Lifetime"** feature have a virtually unlimited expiration (99999 days),\
but are limited to the specific number of devices that can use them.
