CnX Player for Windows 5.0

What stays on your PC. Your library stays on your PC: the folders you add, the list of videos, thumbnails, playlists, favourites, watch history and resume points. CnX Player doesn't upload your videos and doesn't need an account.

Optional diagnostics. CnX Player can send crash and usage reports that help us fix crashes and playback problems.

• The default depends on the Windows country or region. First-run setup shows "Share diagnostic data" switched on, except in the European Economic Area, the United Kingdom and Switzerland, where it starts off and nothing is sent until you turn it on. CnX Player goes by the country or region set in Windows; it never looks up your location to decide. If Windows has no country set, the switch starts off. Skipping setup, or upgrading from an earlier version, follows the same rule, and a switch you turned off stays off.
• You can change it any time in Settings › General › Privacy › Send anonymous diagnostics. The change applies at once, without restarting the app.

When diagnostics are on, CnX Player sends:

• Crash and error reports: the type of error, its numeric error code (shown in hexadecimal), a cleaned-up error message, the name of the operation that failed, and where in CnX Player's code it happened. When an error has an underlying cause, the report also includes that error's type, cleaned-up message and code stack, with limits on their length. If the player takes too long to shut down, the report says whether its quit command was accepted, was still pending, was cancelled or was not sent, or gives the type of its failure; whether the source was local or a network stream; and whether hardware decoding was last observed active, inactive or unknown. It includes the shutdown wait limit and one later report saying whether the forced shutdown completed, left the player running until the app exited, failed, or had not settled within a further 30 seconds, and how long that took (up to that limit). A counter that restarts with the app pairs these two reports within the same launch. The later report may not be sent if the app has already exited. These shutdown details contain no video path or title; error messages and code stacks pass through the same redaction as other diagnostics.
• A short report after a crash or freeze, the next time you open the app: how long the app ran, which screen was open, whether a video was playing (its video format, whether it was HDR, and whether hardware decoding was used), and the error code Windows recorded, with the name and version of the program component that failed.
• Playback problems: the type of error, the video codec, the file extension (for example "mkv"), and whether the video came from a network stream.
• Casting results: the casting technology (for example Chromecast, Roku or DLNA), a Chromecast's model name (for example "Chromecast Ultra"; never the name you gave your TV), the video's format (codec, container, HDR type, and a range for its resolution and frame rate), how the app converted the video for the TV, and whether connecting and playing worked, with the reason when they didn't.
• Library health: the kind of each library folder (for example your Videos folder or a removable drive), how it was added, a range for the number of videos in it (not the exact number), and the results of library maintenance.
• Microsoft Store purchases: which product, and whether a purchase or restore succeeded. Payment details are handled by Microsoft and never reach us.
• App and device details: the app version, the Windows version, the processor type (x64 or Arm64), the graphics adapter's model, memory and driver version, and a random code that changes every time the app starts.

What it never sends: file names, folder names, video titles, subtitles, what you watch or when, the contents of your library, or your name, email address or account details. Before a report leaves your PC, CnX Player removes file paths (a file becomes only its extension and a short one-way code that tells two files apart without naming them), shortens any web address to the site's name only (for example example.com), and removes email addresses, passwords, sign-in tokens and IP addresses from the report.

Where it goes. Reports are sent over an encrypted connection to Microsoft Azure Application Insights, a Microsoft service that stores them for us in the United States. When the app connects, Microsoft's service uses your internet (IP) address to estimate an approximate location (country, region and city). It doesn't keep the full address: an IPv4 address isn't stored at all, and an IPv6 address is stored only as its first part, which identifies an internet provider's network, not your device.

How long. Diagnostic reports in the Azure store are deleted automatically after 90 days. Pathwin Software Pvt. Ltd. also deletes downloaded reports, exports and backup copies within 90 days of the original report. Exporting a report does not restart that period.

No persistent app identifier. CnX Player sends no device ID and no advertising ID, and has no account. Reports from one launch share a random code that changes the next time the app starts.

How we use it. Only to find and fix problems in CnX Player. We do not sell diagnostics or use them for advertising. Access is limited to authorised company management and development personnel who investigate app problems. Microsoft processes the reports for us as our service provider.

Your choices and requests. Turn diagnostics off in Settings at any time; nothing more is sent from then on. Reports carry no name or account, so we usually cannot find the reports from one person. For a question or request, contact support@cnxplayer.com.

Casting. To find TVs and streaming devices, CnX Player searches your local network and talks to the devices directly. When you cast, the video goes from your PC to the device over your own network; it does not pass through our servers. Chromecast and Google TV devices load a CnX Player receiver web page hosted on GitHub Pages. The receiver does not send analytics. GitHub records visitor IP addresses for hosting security, as described in the GitHub Privacy Statement. Loading that page is separate from the video stream on your local network. The CnX Receiver channel for Roku comes from the Roku Channel Store, and Roku's privacy policy covers your Roku device.

Microsoft Store. Purchases, licences and app ratings go through the Microsoft Store, under the Microsoft Privacy Statement. Microsoft handles payment details; they do not reach Pathwin Software Pvt. Ltd.

Google Analytics is used on the website as described below; it is not part of the Windows 5.0 app.
