2. Features of the Use of the Yandex Telemost Service

2.1. Telemost provides the User/Corporate Client with the functional capability to exchange information, send and receive messages, as well as audio, video materials, and images (hereinafter referred to as "Content") with other Users in private and group chats; to create pages intended for publishing Content for viewing by subscriber Users (hereinafter referred to as a "Channel"); and to organize, conduct, and participate in audio and video calls (hereinafter collectively referred to as "Video Calls") with other Users of the Service.

Full access to the Service's functionality is available to the User upon completing the registration process for a new Yandex Services user or by logging into the Service using a previously registered Yandex ID account. To complete the authorization process, the User must specify and confirm a valid phone number linked to their Yandex ID account. If the phone number changes, the User is obligated to promptly update this information via the Service interface and Yandex ID. Yandex reserves the right to verify the validity of the specified phone number by sending a notification requesting confirmation of the continued use of the previously indicated number.

The User is provided with the ability to manage their visibility (searchability) to other Users based on their linked phone number.

When using the Service, information about the User's date of birth, if specified and not hidden in their account, becomes accessible to other Users whose contacts are listed in the User's phone book.

2.2. Telemost enables the User to invoke and utilize third-party software products (bots, chats) and/or interact with third-party organizations (hereinafter referred to as "Partners"), including for the purpose of the User paying for goods, works, or services offered by the Partner.

The User's interaction with Partners and/or their software products is carried out independently by the User (without Yandex's participation); Yandex is not a party to the legal relationships established between Users and Yandex Partners.

The procedures and conditions for processing Users' personal information transmitted by Users to Partners during the use of software products or the purchase of goods, works, or services from the Partner are determined solely by the Partners.

For quality control purposes, including verifying the fact and conditions of interaction between the User and the Partner within the scope of Service usage, as well as regarding the User's payment for the Partner's goods, works, or services; or to comply with legislative requirements, Yandex may retain records of interactions between Users and Partners via relevant Service functions. Access by Yandex and its engaged parties to such interaction history is permitted for the aforementioned purposes, upon request by the interacting parties, and in cases stipulated by law.

If the Service's functionality is used within other Yandex services and products, as well as within third-party services and products, the procedures for processing Users' personal information within the Service may differ. Specific conditions for processing personal information when the Service's functionality is integrated into another service or product must be communicated to the User within the terms of use of the respective service or product.

2.3. Authorized Users utilizing a Yandex ID account acknowledge and agree that, when using the Service, their Yandex ID account name, profile image (avatar), and public display name (previously specified during registration or in Yandex ID settings) will be displayed and accessible to other Users.

Channel Administrators are obligated to adhere to the General Conditions when publishing Content on the Channel. Each Channel Administrator bears responsibility for the Channel's content.

2.5. When publishing Content not intended for viewing by individuals below a certain age established by applicable legislation, the Channel Administrator must mark the Channel or the specific Content with an age restriction notice, or otherwise indicate such viewing restrictions. If the Administrator fails to take these actions, Yandex reserves the right (but is not obligated) to independently place the corresponding age restriction notice if necessary. Yandex bears no responsibility for the accuracy of age restrictions set by the User regarding Content viewing.

2.6. Yandex reserves the right, without prior notice and at its sole discretion, to delete Channel Content or the entire Channel, including in cases where the Content violates applicable legislation, these Terms, or the General Conditions. Yandex may also restrict the Channel Administrator's access to the Service (or to specific Service functions, if technologically feasible) or fully block the User's account upon identifying non-compliance with these Terms, the General Conditions, and/or violations of other regulatory documents. Yandex further reserves the right to apply other measures against the User to ensure compliance with legislation or to protect the rights and legitimate interests of third parties.

2.7. Users may submit complaints regarding Channel content and/or the actions of a Channel Administrator by using the dedicated interface tool within the Channel or via the feedback form at: https://yandex.ru/promo/messenger/feedback.

2.8. Users may initiate Video Calls with other Users within private and group chats using the Service interface.

2.9. Users can also organize Video Calls outside of chats in a video conference format (Video Call Initiator). The Video Call Initiator is entitled to add other Users to participate in such Video Call by copying the individual Video Call URL generated by the Program (the "Video Call Address") in the Program interface and transferring it to persons who can access the Video Call by clicking on the received Video Call Address (the "Participant").

Any Participant is also entitled to copy the Video Call Address and transfer it to persons who can access the Video Call. A Video Call Participant is entitled to access the Video Call:

(a) by following the Video Call Address;

(b) by making a telephone call to the number specified in the Telemost interface using the Video Call extension number. The functionality of connecting to a Video Call via a telephone call may not be available to all categories of Users. The telecom operator may charge the User for such a telephone call in accordance with the terms and tariffs of telecom services. When connecting via telephone, the level of data transfer security may be lower than when using a standard Internet connection.

2.10. The Video Call Initiator is its administrator (hereinafter referred to as the "Administrator"). The Administrator may have access to functionality such as turning off the microphone and/or video transmission of other Participants, pausing the Recording, and other functionalities provided by Telemost. The Administrator may appoint other Participants as Administrators. The Administrator may have the functionality to download data about Participants, which may include the Participant's public display name and email address, the date and time the Participant joined the Video Call, and the date and time the Participant left the Video Call. Administrators shall be solely responsible for checking and admitting Participants who have connected by telephone or via the Internet without proper identification.

2.11. Telemost, on certain operating systems, provides the User with the functionality to demonstrate the screen of their device to other Participants during a Video Call. By activating the device screen sharing mode, the User acknowledges that the Participants will be able to view the information displayed in the active window of the User's device screen at the time of the screen sharing, and also agrees that as a result of the screen sharing, confidential information available to the Participants at the time of the User's screen sharing may be disclosed to the Participants.

2.12. Depending on the operating system used, Telemost may provide the Administrator and Participants with the ability to write and read messages in the Video Call chat.

2.13. Telemost may provide the User with the ability to record a Video Call (hereinafter referred to as the "Recording"). A corresponding notification about the Recording will be displayed in the Telemost interface. By starting to use Telemost, the User confirms and agrees that Recording may be carried out. The Administrator can set a restriction on Recording by the Participants. After the Recording is completed, a copy of it, as well as the history of Users' interactions in Telemost, can be saved both on the User's device and on the Disk of the Video Call Initiator. If there is no space on the Initiator's Disk to store a copy of the Recording, Yandex will send a corresponding notification to the Initiator. Yandex stores a copy of the Recording for 3 calendar days, giving the Initiator the opportunity to clear space on Yandex Disk to save the Recording. After the expiration of this period, the copy of the Recording may be deleted. The User undertakes to use the Recording in accordance with applicable law and shall be solely responsible to third parties for possible violations of third parties' rights related to the implementation of the Recording, its storage on the User's device and its use, including, but not limited to, possible violations of legislation on personal data, on private life and use of images of citizens, copyright, rights to means of identification and other intellectual property objects.

Yandex is not responsible for the User's implementation of the Recording and its subsequent use.

2.14. Telemost may provide the User with the ability to schedule Video Calls by creating an event using the Yandex.Calendar functionality. When creating such an event in Telemost and/or Yandex.Calendar, a field may be provided for specifying a link to the Video Call. The User shall independently set the privacy settings for the information specified in the event fields in Yandex.Calendar and determine the circle of people to whom this information may be available. Yandex is not responsible for such information or for third parties' access to such information.

2.15. Telemost may provide Corporate Clients with the ability to conduct and/or connect to a live video broadcast of a Video Call for viewers, occurring in real time (hereinafter referred to as the "Live Stream"). A Live Stream can be conducted simultaneously by several co-hosts who have access to the corresponding functionality through Telemost.

The Live Stream Initiator can independently configure the ability to connect to it only for the organization's employees in Yandex 360 or for any Users who have the URL of such a Live Stream.

During the Live Stream, Users may be able to interact in the Live Stream chat. After the end of the Live Stream, the chat can be saved on the device of the Live Stream co-hosts.

By participating in the Live Stream as a viewer or co-host, the User shall comply with applicable laws and be solely responsible to third parties for possible violations of third parties' rights related to the implementation of the Live Stream, its storage on the User's device and its use, including, but not limited to, possible violations of legislation on personal data, on private life and use of images of citizens, copyright, rights to means of identification and other intellectual property items.

Yandex is not liable for the User's implementation of the Live Stream and its subsequent use. A Corporate Client is not entitled to conduct several Live Streams simultaneously.

2.16. Telemost may provide the User with functionality that allows Video Call participants to receive a short text summary of what was discussed by the participants during the Video Call (hereinafter referred to as the "AI Summary") to their email address.
