These terms govern the use of the CoViewer extension. By installing and using it, you accept them. If you do not agree, do not use the extension.
The extension synchronizes the playback of a video between several people and adds a chat and reactions. It does not host, store, modify or rebroadcast any video content, and it does not bypass any protection.
Each participant watches the video from their own subscription, on the broadcast service of their choice. The extension gives no access to any content you would not already be allowed to watch. You are responsible for respecting the terms of your broadcaster.
CoViewer and BoxBoxd are independent products. They are not affiliated with, authorised by, endorsed by, sponsored by or in any way officially connected to the Formula One group of companies, including Formula One World Championship Limited and Formula One Licensing BV, the Fédération Internationale de l'Automobile, any competing team, driver or event organiser, or any of the broadcast and streaming services the extension runs on.
All names, marks, logos and images referenced in the product or on this site are the property of their respective owners. Any such reference is descriptive and nominative only, used to indicate compatibility or context, and does not imply any endorsement, partnership or association. Formula 1, F1, FIA, Grand Prix and related names are trademarks of their respective owners.
The extension does not host, store, decrypt, modify, bypass or rebroadcast any video content. Each participant watches through their own subscription on the broadcast service of their choice, and remains responsible for complying with that service's terms.
To post a rating you use your BoxBoxd account. You are responsible for the activity on your account. You can join a party as a guest, without an account, with a simple display name.
A party is shared by link, so strangers may be in it. You agree not to:
For moderation, each member can block another member or report a message. The host of a party can remove a member, who can then no longer rejoin that party. We may restrict access to the service in case of abuse.
The extension, its code and its brand remain our property. You receive a personal, non exclusive right to use it, nothing more.
The service is provided as is, with no guarantee of continuous availability or perfect sync. Playback depends on your broadcaster, your network and your browser. To the extent permitted by law, we are not liable for losses related to the use or unavailability of the extension.
You can stop at any time by uninstalling the extension. We may suspend access for a user who breaks these terms.
These terms are governed by French law. Any dispute falls under the competent courts, absent an amicable agreement.
