Operator and Purpose
tsumo is an independent Mahjong learning and play service operated under the tsumo name. For support, account, privacy, copyright, accessibility, or legal-notice questions, contact support@tsumo.io.
Play eight Mahjong modes, follow interactive tutorials, practice puzzles, and find local clubs. Rules references and a searchable glossary support learning.
Rules and Reference Checks
Rules references are checked against the app, interactive tutorials, and cited ruleset sources. They describe the app’s rules and identify regional or house-rule differences.
Quality, Updates, and Corrections
We update public content when the app behavior changes, a rules explanation becomes unclear, or a user reports a correction that can be verified. Important legal and privacy pages carry their own versioning and update process.
If you spot a rules issue, broken link, accessibility problem, club-listing mistake, or content correction, send the page URL, the issue, and any supporting context through Contact Us.
Advertising and User Trust
tsumo may use Google AdSense on public content pages that are suitable for advertising. Ads are not intended for private gameplay controls, account utilities, legal request forms, admin tools, or under-construction surfaces.
Privacy, cookie, and data-rights pages describe how advertising and optional analytics may process data, where consent controls apply, and how to contact us with privacy questions.
