Terms of service
Last updated 13 November 2026.
Agreement
These Terms of Service ("Terms") govern your access to and use of FlagDecker, the free browser card game available at flagdecker.com, including related features, content, and services (collectively, "FlagDecker"). These Terms are an agreement between you and the operator of FlagDecker. By accessing or using FlagDecker, you agree to these Terms. If you do not agree, do not use FlagDecker.
You must comply with these Terms and all applicable laws. If you use FlagDecker on behalf of another person or organization, you represent that you have authority to bind them to these Terms. These Terms include important disclaimers and limitations of liability. Please read them carefully.
These Terms apply to all users, whether you play as a guest or sign in. Certain features may have additional rules presented in the service, and those rules form part of these Terms. If there is a conflict, the additional rules for that feature control to the extent of the conflict.
The service
FlagDecker is a free browser-based card game. You can play as a guest without creating an account, and signing in is optional. FlagDecker includes gameplay features such as a global leaderboard, a rating for ranked play, private multiplayer rooms where a host creates a room and friends join with a code, display advertising from third-party partners, and analytics used to understand and improve the service.
FlagDecker is provided free of charge. We may add, change, limit, suspend, or discontinue features, content, or portions of FlagDecker at any time. Some features may require sign-in, may be unavailable to guests, or may depend on third-party services such as Google sign-in or advertising partners. We do not guarantee that any particular feature will remain available.
You are responsible for the equipment, browser, internet access, and other requirements needed to access FlagDecker. You are also responsible for any charges your internet or device provider may impose. FlagDecker is intended for personal, non-commercial use unless we expressly permit otherwise.
Eligibility
You must be at least 13 years old to create an account or use FlagDecker, including guest play. Guest play is not for children under 13. If you are under 13, do not use FlagDecker. If you are between 13 and the age of majority in your jurisdiction, you may use FlagDecker only with the involvement and permission of a parent or legal guardian.
By using FlagDecker, you represent that you meet these eligibility requirements and that you have the legal capacity to agree to these Terms or, if required, that a parent or legal guardian has agreed on your behalf. You must comply with any higher age requirements or restrictions that apply in your jurisdiction. We may take steps to restrict or terminate access if we believe you do not meet these requirements.
Accounts
Signing in is optional. If you choose to sign in, you do so using Google. Your use of Google sign-in is also subject to Google's terms and policies, and we do not control Google's services. We do not manage a separate password for your FlagDecker sign-in. You are responsible for maintaining the security of your Google account and for all activity that occurs through your FlagDecker account.
You may set a display name. Display names and other account details may be visible to other users, including on leaderboards, in private multiplayer rooms, and in other parts of FlagDecker. You must choose a display name that complies with these Terms and does not mislead, impersonate, harass, or infringe the rights of others. We may require you to change a display name, may remove or modify a display name, or may refuse or cancel access if a display name or account use violates these Terms.
You must provide accurate information as required by the sign-in process and keep your account information current. You must not create accounts or use sign-in methods to evade restrictions, manipulate rankings or ratings, impersonate others, or interfere with FlagDecker. You must promptly contact us if you believe your account has been accessed without authorization. We may suspend or terminate accounts as described in these Terms.
Guest play
You may play FlagDecker as a guest without creating an account or signing in. Guest play is subject to these Terms, including the eligibility requirements. Guest play is not for children under 13. Guests may have access to a more limited set of features than signed-in users, and some features, such as leaderboard participation, ranked ratings, or private multiplayer rooms, may require sign-in or may be unavailable or limited for guests.
Guest play may rely on temporary identifiers, local storage, or other limited mechanisms to support gameplay. Guest progress, preferences, display names, room participation, or other guest data may be lost, may not be recoverable, and may not transfer to a signed-in account. We do not guarantee that guest data will be preserved. You are responsible for any activity that occurs during your guest use.
If you stop using guest play, you may simply close FlagDecker. Because guest use may not be associated with an account, some requests to access, correct, or delete guest data may be limited. You may contact us using the contact details below if you have questions about guest play.
Leaderboard and ratings
FlagDecker includes a global leaderboard and a rating for ranked play. Leaderboard positions and ratings are gameplay features intended to reflect participation and performance in FlagDecker. They may be visible to other users, including alongside your display name. Ratings and leaderboard positions may change as you play and as other users play. We do not disclose the internal formulas, calculations, thresholds, or other details used to determine ratings or leaderboard positions.
You must not manipulate, exploit, or attempt to manipulate the leaderboard or ratings. Prohibited conduct includes cheating, using unauthorized tools, colluding with others, win trading, creating or using multiple accounts to affect rankings or ratings, abusing bugs, or otherwise interfering with fair play. We may investigate suspected manipulation and may adjust, remove, reset, or recalculate ratings or leaderboard entries, with or without notice, to protect the integrity of FlagDecker.
Leaderboard and rating information is provided for gameplay and informational purposes only. We do not guarantee that any rating, rank, or leaderboard position is accurate, complete, or available at any particular time. We may correct errors, remove entries, or change how leaderboard and rating features work. You may not use leaderboard or rating data for commercial purposes or in a way that violates these Terms.
Multiplayer rooms
FlagDecker includes private multiplayer rooms. A host creates a room, and friends join with a code. Room codes are intended to allow invited participants to join a private room. You are responsible for sharing room codes only with people you trust. Room codes are not a secure way to share confidential information, and you should not post them publicly or share them with anyone who should not join the room. We do not guarantee that a room will remain private or that only intended participants will join.
The host may control certain room settings and may be able to start, close, or manage the room, depending on the features available. Hosts and participants must comply with these Terms, including the acceptable use and fair play rules. You must not use multiplayer rooms to harass, discriminate unlawfully, impersonate, distribute prohibited content, or interfere with other users. We may close rooms, remove participants, or restrict multiplayer access if we believe there is a violation, risk, or operational need.
Multiplayer rooms depend on the availability of FlagDecker and related services. We may change room features, impose limits, or discontinue multiplayer rooms. We are not responsible for the conduct of hosts or participants, and you use multiplayer features at your own risk. Do not share personal, confidential, or sensitive information in rooms.
User content
FlagDecker may allow you to submit or display content, such as a display name, room names or identifiers, messages, or other materials, depending on the features available ("User Content"). You retain ownership of your User Content. By submitting or displaying User Content on or through FlagDecker, you grant the operator of FlagDecker a worldwide, non-exclusive, royalty-free, transferable, and sublicensable license to host, store, reproduce, display, modify, adapt, publish, and distribute your User Content as necessary to operate, provide, promote, and improve FlagDecker, and to comply with law and enforce these Terms.
You represent and warrant that you have all rights necessary to submit your User Content and to grant the license above, and that your User Content does not violate these Terms, infringe any third-party rights, or violate any law. You are solely responsible for your User Content. We do not endorse User Content and are not responsible for it. We may, but are not obligated to, monitor, review, or remove User Content. We may remove or modify User Content if we believe it violates these Terms or creates risk.
User Content may be visible to others. Do not submit personal, confidential, or sensitive information that you do not want to be seen, stored, or shared. If you believe User Content violates your rights or these Terms, contact us using the contact details below. We may provide tools to report or block content or users, but we do not guarantee that all violations will be detected or removed.
Acceptable use
You must use FlagDecker lawfully and respectfully. You agree not to:
- violate any applicable law, regulation, or third-party right;
- use FlagDecker if you are under 13 or otherwise do not meet the eligibility requirements;
- harass, threaten, bully, defame, or discriminate against any person or group;

This list is not exhaustive. We may determine whether conduct violates these Terms and may take action as described in these Terms. We may remove content, restrict features, suspend or terminate access, or report conduct to appropriate authorities if required or appropriate.
Cheating and fair play
FlagDecker is intended to be played fairly. You must not cheat, exploit, or interfere with gameplay, other users, or the operation of FlagDecker. Prohibited conduct includes using unauthorized software, bots, scripts, automation, modified clients, or third-party tools; exploiting bugs, glitches, or errors; manipulating game outcomes; colluding with other users; win trading; intentionally disconnecting or interfering with matches; and using multiple accounts or other methods to manipulate ratings, leaderboards, or matchmaking.
You must not attempt to discover, access, or use internal game data, formulas, rating calculations, score thresholds, or other non-public information, except as expressly permitted by us. You must not abuse reporting or moderation systems, including by submitting false reports or encouraging others to do so. You must not encourage or help others to violate these fair play rules.
We may investigate suspected cheating or unfair play and may take action to protect FlagDecker. Actions may include warnings, content or feature removal, rating or leaderboard adjustments, removal from leaderboards, suspension, or termination of access. We may use automated and manual methods to detect and address cheating. We do not disclose all detection methods or enforcement details. Our decisions are intended to protect the integrity of the game, and we may take action even if we cannot identify every participant or every instance of misconduct.
Virtual items
FlagDecker may include virtual cards, gold, and similar items or features. Virtual items are gameplay elements only. They have no real-money value and cannot be bought, sold, traded for real money, or cashed out. They are not property, currency, or financial instruments. You do not own virtual items; you receive a limited, revocable, non-transferable, and non-exclusive license to use them within FlagDecker as part of your use of the service, subject to these Terms.
Virtual items may be changed, removed, reset, or made unavailable at any time, including as part of game updates, balancing, maintenance, enforcement, or feature changes. We do not guarantee that any virtual item will remain available or retain any particular characteristic. Because FlagDecker is free to use and virtual items have no real-money value, you are not entitled to any refund, compensation, or exchange for virtual items, except where required by applicable law.
You must not attempt to buy, sell, trade, transfer, or cash out virtual items outside FlagDecker, or use virtual items for any commercial purpose. You must not use third-party services to obtain, modify, or transfer virtual items. Any attempt to do so may result in loss of virtual items and other action under these Terms.
Intellectual property
FlagDecker and its content, features, software, code, graphics, artwork, designs, text, logos, trademarks, service marks, and other materials are owned by the operator of FlagDecker or its licensors and are protected by intellectual property and other laws. These Terms do not grant you ownership of FlagDecker or its content. You receive a limited, revocable, non-exclusive, non-transferable, and non-sublicensable license to access and use FlagDecker for personal, non-commercial use, subject to these Terms.
You must not copy, reproduce, modify, adapt, translate, create derivative works from, distribute, publicly display, publicly perform, reverse engineer, decompile, disassemble, scrape, or otherwise exploit FlagDecker or its content except as expressly permitted by law or by us in writing. You must not remove or alter any copyright, trademark, or other proprietary notices. The FlagDecker name and logo, and related names and logos, are trademarks or service marks of the operator of FlagDecker or its licensors. You may not use them without prior written permission.
If you provide feedback, suggestions, or ideas about FlagDecker, you grant us a worldwide, perpetual, irrevocable, royalty-free, transferable, and sublicensable license to use, modify, and incorporate that feedback without compensation or attribution to you. If you believe content on FlagDecker infringes your intellectual property rights, contact us using the contact details below so we can review the matter.
Advertising
FlagDecker displays advertising from third-party partners to support the free service. We do not control third-party advertisements, and we do not endorse the products, services, or content they promote. Your interactions with advertisers, including any purchases or promotions, are solely between you and the advertiser. You should review the advertiser's terms and policies before engaging with them.
Third-party advertising partners may use cookies, local storage, device identifiers, or similar technologies to deliver and measure advertisements and to provide related services. These partners may collect information about your use of FlagDecker and other websites or services, subject to their own privacy policies and applicable law. We do not name specific advertising vendors in these Terms and do not control how third-party partners handle information. You may have choices through your browser, device, or the partners' own tools.
Advertising may affect the availability or appearance of some features, and ad blocking or similar tools may affect your experience. We are not responsible for third-party advertisements or for any loss or damage arising from your dealings with advertisers. Questions about a specific advertisement should be directed to the advertiser.
Availability
FlagDecker is provided on an "as available" basis. We aim to keep FlagDecker available, but we do not guarantee that it will be uninterrupted, timely, secure, or error-free. FlagDecker may be unavailable due to maintenance, updates, technical issues, outages, attacks, or other events. Some features depend on third-party services, including Google sign-in, third-party advertising partners, analytics providers, and may be affected by those services.
We may change, suspend, or discontinue any part of FlagDecker at any time, with or without notice. We may also impose limits on use or storage. We are not liable for any unavailability, delay, or failure of FlagDecker or any feature, to the maximum extent permitted by law. You are responsible for maintaining any information you need and for using FlagDecker in a manner that does not rely on continuous availability.
Disclaimers
To the maximum extent permitted by applicable law, FlagDecker and all content, features, and services are provided "as is" and "as available" without warranties of any kind, whether express, implied, statutory, or otherwise. We disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, and any warranties arising from course of dealing or usage of trade.
We do not warrant that FlagDecker will be accurate, reliable, complete, secure, uninterrupted, error-free, or free of viruses or other harmful components. We do not warrant that defects will be corrected or that FlagDecker will meet your requirements or expectations. You use FlagDecker at your own risk. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you. In that case, the exclusions apply to the fullest extent permitted by law.
Limitation of liability
To the maximum extent permitted by applicable law, the operator of FlagDecker and its licensors, service providers, and partners will not be liable for any indirect, incidental, special, consequential, punitive, or exemplary damages, or for any loss of data, profits, revenue, goodwill, or business opportunity, arising out of or relating to your use of or inability to use FlagDecker, even if advised of the possibility of such damages.
To the maximum extent permitted by applicable law, the total liability of the operator of FlagDecker and its licensors, service providers, and partners for any claim arising out of or relating to these Terms or FlagDecker will not exceed the maximum amount permitted by law. Because FlagDecker is free to use, you acknowledge that this limitation is reasonable and reflects the nature of the service. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law.
Termination
We may suspend, restrict, or terminate your access to FlagDecker, with or without notice, if we reasonably believe you have violated these Terms, created risk for FlagDecker or others, infringed rights, engaged in cheating or unfair play, or if required for legal, operational, or security reasons. We may also remove or modify content, reset or adjust ratings or leaderboard entries, or take other action we consider appropriate.
You may stop using FlagDecker at any time. If you have an account, you may request account deletion as described below. Termination does not automatically entitle you to any refund, compensation, or restoration of data, ratings, leaderboard positions, or virtual items. We are not obligated to provide notice before taking action if we believe immediate action is necessary.
Sections of these Terms that by their nature should survive termination will survive, including provisions concerning intellectual property, disclaimers, limitation of liability, account deletion, and contact. Termination of your access does not waive any rights or remedies available to us.
Account deletion
If you have a FlagDecker account, you may request deletion of your account by using the contact page at https://flagdecker.com/contact/ or by emailing support@flagdecker.com. We may need to verify your request, including by confirming control of the associated Google account, before processing it. Please provide enough information for us to identify your account.
Subject to applicable law and our legitimate needs, we will delete or anonymize account information associated with your account. We may retain certain information for legal, security, fraud prevention, backup, dispute resolution, or enforcement purposes, and for as long as necessary for those purposes. Deleting your account may remove or anonymize your display name, leaderboard entries, ratings, or other account-related data, and may prevent you from accessing features that require sign-in.
Account deletion does not automatically delete information held by third parties, including Google, third-party advertising partners, or analytics providers, and does not delete content that other users may have copied or stored. Guest data may not be associated with an account and may not be recoverable or deletable through account deletion. You may stop using guest play at any time. Questions about deletion can be sent to the contact page or support email above.
Changes
We may update these Terms from time to time. When we make changes, we will post the updated Terms on or through FlagDecker and indicate the effective date. Changes are effective when posted unless we state otherwise. Your continued use of FlagDecker after changes become effective means you accept the updated Terms. If you do not agree to the updated Terms, you must stop using FlagDecker.
For material changes, we may provide additional notice where appropriate. You are responsible for reviewing these Terms periodically. We may also change, suspend, or discontinue features as described in these Terms. No change to these Terms will apply retroactively unless required by law or expressly stated.
