	On installation, the application creates a unique identifier in the form of an alphanumeric code (UID) based on information about your Windows operating system. The UID is built in such a way that the information used to create it cannot be re-established in any way. The UID is sent to our server when requesting software updates and is used to determine the number of active users (application popularity). In addition, the name of used localization is send to the server. This information is necessary in order to determine the language in which the server should return the list of updates. You can refuse to transmit this information by disabling the update checker plugin, but you will stop receiving updates in semi-automatic mode. 
	Additionally, app can send crash-reports in automatic (for alpha/beta-versions) and manual (release versions) modes. Crash-reports contains general information about PC's hardware, OS details, list of loaded modules (plugins), last actions log and crash stack trace.

	3.2. Authorization of Third Party Services
	Authorization of third party services is optional and is not required for the software to work. Third party services can be authorized using a username and password (Basic Authorization) or using OAuth, that allowing us to avoid working directly with usernames and passwords, replacing them with a user_id (unique user identifier) ​​and access_token (used to confirm authorization when sending requests to the service). In Basic Authorization mode, the application is forced to store credentials to re-use these to access the service in the future. To ensure data security, these credentials are stored in app in encrypted form. You can revoke authorization to third-party services at any time. This can be done both via the service itself or through the app:
	• For cloud storages (OneDrive, Dropbox, Yandex.Disk, etc.), simply remove cloud storage from the list using the remove command from the context menu.
	• For scrobblers, refer to the App Settings menu in "Settings \ Plugins \ Scrobbler" and click "Log off" for each service profile.

	All information received from third party services which the user has authorized through this software is only presented directly to the user and is NOT transmitted to our servers or servers of our partners, except of the servers of the third party services themselves. This software can store a local copy of the data received in order to reduce the number of requests to service. Data is only stored in the app settings folder in binary form (unreadable without special tools). Local copies of the data are deleted automatically upon revocation of authorization (see Section 3.5) or on deletion of this software completely using our uninstall tool.

	3.4. Required Permissions to Work with Third Party Services
	For this software to function correctly with third party services, the user must accept the following permissions when authorizing the service:
	• OneDrive: offline_access - increases the lifetime of the access_token (see Section 3.2), thereby reducing the number of user re-authorization requests. Files.Read - this permission is required in order to obtain a list of files (audio files) located in the user's cloud storage for further playback.
	• WebDAV: despite the fact that when using the WebDAV protocol services do not request specific permissions, the application actually gets full access to the cloud storage and this software works only with audio files and only in "read-only" mode.
