Fortress:Card is an online strategy board game (web application) published and operated by DSE Deep System Entertainment. By opening Fortress:Card, starting a game, using the tutorial, playing against bots or other players, or otherwise using the service, you agree to these Terms on your own behalf and confirm that you have read, understood, and accepted them.
If you do not agree to these Terms in their entirety, you must not access or use Fortress:Card.
The Privacy Policy is incorporated into these Terms by reference. In case of conflict between these Terms and the Privacy Policy regarding data processing, the Privacy Policy governs data matters and these Terms govern service use.
DSE Deep System Entertainment (DSE) publishes and operates Fortress:Card, including the web client, online game services (solo and multiplayer sessions, matchmaking, rankings), tutorial, and related features.
DSE Deep System Entertainment does not guarantee that Fortress:Card or its online services will remain available forever. Availability may change without prior notice except where applicable law requires otherwise.
2. Description of the service
Fortress:Card is a digital adaptation of a secret-role city-building card game. The service currently includes or may include:
- Solo play against AI opponents.
- Online multiplayer sessions (when enabled).
- An interactive tutorial.
- Local player profile (display name, ELO rating, cosmetic preferences).
- In-game journal, character guide, and turn-order tools.
- Future features such as accounts, shop, ranked seasons, or cosmetics may be added without prior notice.
- An internet connection is required for online play and server-synchronised features.
- Beta or experimental features may appear without notice and may be changed or removed at any time.
3. What you accept when using Fortress:Card
- You are at least 13 years old (or the minimum digital consent age in your country, if higher) and legally allowed to use Fortress:Card; you will not permit children under 13 to use the service on your device.
- Game data (moves, display name, session identifiers, ELO, and related metadata) may be transmitted to and processed on servers operated by DSE Deep System Entertainment in France to run matches, rankings, and anti-abuse measures.
- Fortress:Card is provided on an “as is” and “as available” basis; DSE Deep System Entertainment does not warrant uninterrupted, error-free, or permanent availability.
- Rankings, ELO, cosmetics, and other in-game rewards have no cash value unless DSE Deep System Entertainment states otherwise in writing.
- DSE Deep System Entertainment may apply rate limits, moderation, technical restrictions, and required updates without prior notice where permitted by law.
4. Eligibility and your responsibilities
You represent that your use of Fortress:Card complies with applicable law in every jurisdiction from which you access the service.
If you are between 13 and 17 years old (or the age of digital consent in your country, if higher), you confirm that you have permission from a parent or legal guardian, or that applicable law permits you to use online services at your age without separate parental consent.
- You are responsible for all activity on your device and for the display name and behaviour associated with your play.
- You must not harass, threaten, defame, or abuse other players through in-game names, chat (when available), or any other channel linked to Fortress:Card.
- You must not cheat, exploit bugs, use unauthorised automation, reverse-engineer the clients or servers, or interfere with fair play.
- You must not impersonate DSE Deep System Entertainment staff or other users.
- Commercial use of Fortress:Card (reselling access, operating a paid service on top of Fortress:Card, or bulk automated access) requires prior written authorisation from DSE Deep System Entertainment.
5. Accounts, guest access, and player data
- When you click Enter on the welcome screen, Fortress:Card automatically creates a guest account on our servers with a system-generated display name (format User##xxxx, where # is a digit and x is a letter or digit). Guest accounts are linked to your session and originating IP address for abuse prevention.
- Guest account data is retained on our servers until you delete the account or we remove it under these Terms. You may request deletion by email once our support address is published; until then, contact us through the channels listed in Section 13.
- Guest accounts are not eligible for ranked ELO or competitive leaderboards when those features launch. Only registered accounts with a username and password may participate in ranked play.
- You may upgrade a guest account to a registered account at any time from the Account screen by choosing a unique username (3–16 characters, letters and numbers only, case-sensitive; cannot start with "User", which is reserved for guest accounts) and a password.
- Registered accounts store a password hash on our servers; we never store plain-text passwords.
- Each account is assigned an internal persistent identifier (UUID) for technical operations and future service evolution. This identifier is not displayed in the game interface.
- Fortress:Card may also store gameplay preferences such as your one-time tutorial choice, session identifiers, and your IP address when you connect (for abuse prevention). See the Privacy Policy for details.
- You are responsible for your device security. DSE Deep System Entertainment is not obligated to restore access if you lose your session and have not created a registered account.
6. Fair play and sanctions
DSE Deep System Entertainment may investigate suspected violations and take action including warnings, match invalidation, ELO adjustment, temporary restrictions, or permanent bans from online features.
Sanctions may be applied without prior notice where necessary to protect the service or other users, subject to applicable law.

Fortress:Card is an original digital implementation published by DSE Deep System Entertainment. It is not affiliated with, endorsed by, or sponsored by any third-party board-game publisher unless expressly stated.
