What is DM Value?
DM Value is an independently operated, unofficial fan-made browser tool for deck preparation and test play. It combines deck building, shared-URL deck import, searchable Japanese card information, two-sided solo testing, and an Experimental Beta online table. See How It Works for the complete flow.
Can I read about the service without an account?
Yes. The home overview, About, How It Works, FAQ, Known Limitations, Privacy Policy, Terms, Contact, and Disclaimer pages are public. Google Sign-In is required only when you enter account-linked application features such as saving decks or joining authenticated online rooms.
Does DM Value distribute or retrieve official card images?
No. Core screens use original text-based proxy faces and do not automatically fetch official card artwork from a publisher or third-party site. Product names, card names, rules text, artwork, and other third-party materials remain the property of their respective owners. Read the Disclaimer for the project's full notice.
What happens to images selected in Local Asset Mode?
The browser reads and processes the files you select on your device. Matched images are stored in browser-local storage for the current browser profile and are not uploaded to DM Value servers. You can remove them through Settings; clearing site data may remove them as well. More detail is available in the Privacy Policy.
Does the simulator automatically enforce every card rule?
No. DM Value provides table operations and selected workflows, but it is not an official rules source or tournament judge. Some card-specific effects, unusual interactions, and recovery steps require manual resolution. The current boundaries are documented on the Known Limitations page.
How stable is online play?
Online play is an Experimental Beta / Test Stage feature. Players may need to coordinate through chat, resolve some effects manually, or recover after a connection interruption. Deck building and two-sided Solo Play are the more stable core of the Public Beta.
Does DM Value support mobile browsers?
A desktop browser is recommended. Mobile is not officially supported, and the application may require horizontal scrolling or a larger screen for the duel table and deck tools. The public information pages remain available on mobile so visitors can review the service and its policies.
Where may advertising appear?
DM Value may use Google AdSense only after Google approves the site and the required technical and consent setup is complete. Advertising is not placed inside the duel table or beside gameplay controls. Ordinary information or lobby pages may be considered separately, with ads clearly distinguishable from navigation and application actions.
How can I report a problem or rights concern?
Use the Contact page for technical support, privacy requests, abuse reports, or rights-holder notices. Include the affected page or feature and enough detail to investigate, but do not send passwords, authentication tokens, or unnecessary identity documents.
