Unique user key - concatenates a type of user authentication and an auto-generated user ID in the authentication service.
Example: firebase\_jfqmTeaifwPNuOwIofHHdhY89Po1
where firebase means that the user is authorized with Firebase authentication type and jfqmTeaifwPNuOwIofHHdhY89Po1 is an auto-generated unique user ID in the Firebase service.
| | Description | string | (optional) Additional user information | | Auth method | string | User authentication method (e.g. pango, firebase, etc) | | Registration date | timestamp | Date and time of user registration on the Platform | | Project | string | Project ID for this user (is chosen by the project owner) | | Status | boolean | Users status: 0 - active, 1 - blocked | | License | number | License ID for the current user (license limits the number of devices and is chosen from the predefined list). | | Traffic limit | number | The per-day or per-month traffic limit for the current user (bytes) | | Extref | string | (optional) additional description | | Country | string | Approximate user country | | Auth profile | string | Public profile of the user. It is received from the response of the authentication service. | | Activated devices | number | Number of activated devices | Device data includes the following parameters: | **Property Name** | **Type** | **Description** | | ----------------- | --------- | ------------------------------------------------------------------------------------------- | | ID | number | Device ID. The Platform generates a unique Device ID. | | Device ID | string | A unique device identifier, auto-generated by SDK. It is different from the real device ID. | | Registration date | timestamp | Date and time of the device registration on the Platform | | Name | string | Factory name of the device | | Type | string | android, ios, etc. | | User Name | string | auto-generated user ID of this device | | Status | boolean | Device status: 0 - is active, 1 - is blocked | Data is preserved for **12 months,** if not deleted by project managers through the platform management console, and has any activity. ## VPN session statistic For each user session, the following data is collected: | **Property Name** | **Type** | **Description** | | ----------------- | --------- | ----------------------------------------------------------------------------------------------------- | | Session ID | string | A unique auto-generated session identifier (e.g a3f727d261640aa65cc3c89a47080c2b) | | Device ID | integer | A unique auto-generated device identifier | | Carried ID | string | A unique auto-generated identifier | | User ID | string | A unique auto-generated identifier | | Start time | timestamp | When has the session started? (e.g 9999-12-31 23:59:59.999999 UTC) | | End time | timestamp | When has this session stopped? (e.g 9999-12-31 23:59:59.999999 UTC) | | RX | integer | Amount of traffic received (bytes) | | TX | integer | Amount of traffic transmitted (bytes) | | Server ID | integer | VPN-node ID for the current session on a particular device (is valid until the session is terminated) | | Internal IP | string | Internal session IP. It is **different** **from the real** device **IP**. | Data is preserved for **12 months.** ## SDK events SDK sends various events to the platform. This data is used for quality connection monitoring and issue investigation. Data is preserved for **3 months.** Full events parameters are described in the following document: {% content-ref url="/pages/-M6fZUk0Z2ZDvkJjXFBE" %} [What analytic data is collected by your SDK?](/paas/faq/general/what-analytic-data-collect-your-sdk.md) {% endcontent-ref %}
