The contractual relationship between Chessivity and users continues to be governed by these Terms of Use unless mandatory provisions provide otherwise.

1.5. Deviating terms of users shall apply only if Chessivity has expressly agreed to their applicability in text form.

2. Incorporation of the Terms of Use and Contract Language

2.1. A user agreement between Chessivity and the user is concluded when the user registers a user account and agrees to these Terms of Use.

2.2. To the extent that functions of the Platform can be used without registration, the relevant provisions of these Terms of Use shall apply upon use of the respective function.

2.3. The authoritative contract language is German.

2.4. Chessivity may provide translations of these Terms of Use, in particular in English. Such translations are provided for ease of understanding. In the event of inconsistencies between different language versions, the German version shall prevail.

3.1. Chessivity is a digital platform in the field of chess. The Platform may in particular provide functions for profiles, posts, comments, images and other media, social interactions, direct messages and group chats, training and activity tracking, calendars, challenges, collections and libraries, statistics, chess-related training and analysis functions, notifications, gamified elements and connections to external chess platforms.

3.2. The specific range of functions may change on an ongoing basis. Individual functions may be added, further developed, restricted, temporarily deactivated or discontinued. Section 22 applies in particular to such changes.

3.3. Chessivity does not owe any specific sporting, chess-related, training-related or economic outcome. Content, statistics, calendar functions, training evaluations, challenges, recommendations, translations and other displays serve in particular to inform, organise, motivate, entertain and support users.

3.4. Where automatically generated translations, recommendations, classifications or comparable functions are provided, they may be incomplete or inaccurate. Users should independently verify important information.

3.5. Chessivity is not a chess server platform for officially rated games unless such a function is expressly offered. Chessivity assumes no responsibility for ratings, rankings, decisions or measures taken by external chess platforms.

4. Registration, User Account and Minimum Age

4.1. The creation of a user account is required for certain functions of the Platform.

4.2. Users must provide accurate, current and complete information during registration to the extent such information is requested. Required changes must be updated in the user account.

4.4. Persons between the ages of 14 and 18 may use the Platform only to the extent they are entitled to do so under the laws applicable to them. Where the consent of a legal representative is required for the use of an individual function or the conclusion of a legal transaction, such consent must be obtained.

4.5. Deviating or stricter privacy, security and usage settings may apply to users who are minors. This may in particular concern the visibility of profiles and content, interaction options, notifications and individual gamified functions.

4.6. Chessivity may request confirmation of age and may suspend or delete user accounts if there are specific indications that a person does not meet the age requirements. Comprehensive identity or age verification shall take place only where legally required or objectively justified in an individual case.

4.7. Users are responsible for keeping their login credentials confidential and protecting their user accounts against unauthorised access. User accounts may not be shared with third parties.

4.8. Chessivity may refuse registration or restrict, suspend or delete a user account if there are legitimate reasons to do so, in particular in the event of false information, misuse, security risks or violations of these Terms of Use.

5. Login, External Chess Accounts and Third-Party Services

5.1. The Platform may provide different registration and login methods, in particular registration by email and password as well as login or linking through third-party services such as Lichess, Google or other supported providers.

5.2. Users may link, enter or manage only external accounts that belong to them or that they are authorised to use.

6.2. Stricter default settings may apply to users who are minors. In particular, their profiles, content and activities may be visible only to a restricted audience by default.

6.3. To the extent that privacy settings are provided, users may restrict certain profile information, activities or content. The specific scope depends on the functions available at the relevant time.

6.4. Publicly visible content may be viewed, shared, quoted, copied, stored or archived by third parties or indexed by search engines. Chessivity cannot fully prevent such content from continuing to exist outside Chessivity’s sphere of influence after it has subsequently been deleted.

6.5. Even where private or restricted settings are used, it cannot be ruled out that other persons have previously viewed, stored or otherwise perceived content.

6.6. Users should not publish confidential, sensitive or purely private information if they do not want other persons to see such information.

7. User Content

7.1. Users may create, upload, publish, comment on, share or otherwise provide content on the Platform, in particular text, images, other media, chess positions, games, training activities, calendar content, direct messages, comments, profile information, links and other posts ( “User Content”).

7.2. Users retain ownership of the rights to their User Content to the extent such rights belong to them.

7.3. Users are responsible for their User Content. They warrant that they hold all required rights and that their User Content does not violate any laws, third-party rights or these Terms of Use.

7.4. In particular, users may not provide content that is unlawful, insulting, defamatory, discriminatory, hateful, threatening, harassing, pornographic, glorifies violence, extremist, fraudulent, misleading, spam-like or otherwise abusive.

7.5. Content that infringes copyright, trademark rights, personality rights, data protection rights, trade secrets or other third-party rights is also prohibited.

8. Rights of Use to User Content

8.1. By uploading, creating or publishing User Content, users grant Chessivity a non-exclusive, worldwide, royalty-free and, to the extent required, transferable and sublicensable right to use such User Content for the operation, provision, display, technical processing, safeguarding, moderation and further development of the Platform.

8.2. This right of use includes in particular the right to store, reproduce, technically process, format, compress, translate, make publicly available and display User Content, to display it in feeds, profiles, search functions, previews, notifications, direct messages, group chats and other Platform functions, and to process it for security, moderation and abuse-prevention purposes.

8.3. Where User Content is published publicly, it may be viewed, shared, forwarded, quoted, commented on or otherwise used by other users within the Platform and its functions where the functions available at the relevant time permit this.

8.4. Publicly published User Content may also be used to present and promote the Platform, in particular through links, previews or the display of public posts in Platform-related communication channels. Any further use of identifiable User Content for independent advertising campaigns shall take place only where legally permissible and, where required, subject to separate consent.

8.5. The grant of rights is limited to the extent required or appropriate for the stated purposes.

8.6. Following deletion of a user account or individual User Content, the grant of rights generally ends unless continued use is required for technical, legal, security-related, documentation-related or legitimate Platform-related reasons. Anonymised or effectively aggregated content and data may continue to be used.

9. Images, Media and Technical Processing

9.1. Users may upload or publish only images, media and other files for which they hold the required rights or for which they have sufficient permission to use them.

9.2. In particular, users may not upload images or media that infringe personality rights, copyright, trademark rights, data protection rights or other third-party rights.

9.3. For the operation of the Platform, Chessivity may technically process uploaded images and other media. This includes in particular storage, hosting, resizing, cropping, compression, format conversion, the creation of thumbnails, caching and technical delivery.

9.4. Chessivity may use automated or manual checks of images, media and other content, in particular to detect prohibited, unlawful or abusive content. Such checks do not create an obligation on the part of Chessivity to review all content in advance and do not release users from their own responsibility.

9.5. If Chessivity is subject to claims by third parties due to content provided by a user, the user shall indemnify Chessivity against justified claims in accordance with statutory provisions and to the extent legally permissible, provided that the user is responsible for the infringement.

10. Calendar and Calendar Subscription Links

10.1. The Platform may provide calendar functions for the creation, storage, display and organisation of chess-related or other usage-related events.

10.2. Where Chessivity provides calendar subscription links or comparable technical sharing links, users are responsible for keeping such links confidential.

10.3. Persons who obtain access to such a link may view the calendar information made available through it without logging in to Chessivity, subject to the technical functionality provided at the relevant time.

10.4. Where the Platform provides the relevant option, users may revoke or regenerate such a link. After a link has been shared, Chessivity cannot fully prevent calendar information previously retrieved through it from remaining stored outside the Platform.

10.5. Chessivity assumes no responsibility for the functionality of external calendar applications or for the sharing of a calendar subscription link initiated by users.

11. Direct Messages and Group Chats

11.1. The Platform may provide 1:1 direct messaging and group chats with rich text, inline chess moves, shared-post embeds, reactions, replies, forwards and comparable messaging functions.

11.2. Messages sent through these functions constitute User Content within the meaning of Section 7. The rules on prohibited content, rights of use, moderation and reporting apply accordingly.

11.3. Messages from users who are not connected to the recipient may arrive as a message request. The recipient may accept, decline or message-block the sender. Declining a request hides the conversation without necessarily blocking the sender from the profile or feed.

11.4.Users may use a separate message-only block that stops messaging without necessarily hiding the other person's profile or posts. Chessivity does not guarantee that a blocked party will be informed of the block.

11.5. Direct messaging on Chessivity is not end-to-end encrypted and does not provide guaranteed confidentiality. Users should not use it for highly sensitive information. Other participants may copy, forward, store or otherwise use message content outside Chessivity.

11.6. Chessivity does not guarantee instant delivery, permanent availability, read receipts or uninterrupted realtime updates for messages.

11.7. Group chats may provide roles, invitations by handle, invite links, @mentions, pinned messages and group avatars. Users are responsible for keeping invite links confidential, comparable to calendar subscription links under Section 10. Depending on the link settings, persons with access may join a group without logging in to Chessivity.

11.8. Users may edit their own messages only within the time window provided on the Platform and delete their own messages only within the deletion window provided on the Platform. Chessivity may remove messages or suspend conversations for moderation reasons outside those windows.

11.9. Users may report individual messages or conversations. Chessivity may review reported threads and take appropriate moderation measures.

11.10. Unsolicited mass messages, spam and abusive use of messaging functions are prohibited, in particular pursuant to Sections 13 and 15.

11.11. Chessivity may send service or announcement messages from official platform accounts, such as @chessivity.

12. Notifications

12.1. Chessivity may provide usage-related notifications within the Platform or, where envisaged, by email, push notifications or comparable channels.

• m) systematically extract, copy or exploit content or data from the Platform or use such content or data for competing services without Chessivity’s consent;
• n) link or manage external accounts belonging to third parties without authorisation;
• o) use the Platform for illegal betting, fraud, manipulation, cheating services, account trading or comparable abusive purposes.
