麻雀競技場 (“the Service”, “we”, “us”) is a free, personal mahjong scorekeeping tool operated by an individual. This Privacy Policy explains what personal data we collect, how we use and share it, and the rights you have. By using the Service you agree to this policy.
We use personal data to:
The Service lets you enter a name for a player who does not have an account. You enter that name on their behalf, and it is visible only to you and the other players in that room. Please enter only what is appropriate, and do not enter another person’s information that you have no reasonable basis to use.
We do not sell your personal data. We share it only with the service providers that help us run the Service:
These providers may store and process data on servers located outside Hong Kong, including in the United States. We may also disclose data where required by law.
We use essential cookies to keep you signed in — the Service cannot work without them — and analytics cookies set by PostHog to measure usage. You can block or delete cookies in your browser settings, but parts of the Service, including sign-in, may stop working.
We keep your account and game records for as long as your account exists. When you ask us to delete your account, we remove your personal data from our active systems; residual copies may persist for a short time in backups or provider logs before they expire.
Under the Hong Kong Personal Data (Privacy) Ordinance you may request access to or correction of your personal data, and you may ask us to delete your account and associated data. Email us at support@topwealtharena.com and we will respond within a reasonable time. We may need to verify your identity before acting on a request.
Please note that deleting your account may also remove games you hosted, which can affect the records other players kept of those games.
The Service is not intended for anyone under 16. If you are under 16, you may use it only with the consent and supervision of a parent or guardian. If we learn that we hold the personal data of a child under 16 without such consent, we will delete it.
We protect your data with access controls — including row-level security and server-side-only writes — and rely on the security of our service providers. No online service can be completely secure, so we provide the Service “as is”.
We may update this Privacy Policy from time to time. The “Last updated” date above shows the current version, and we will highlight significant changes in the app or on this page.
For any question or request about your privacy, email us at support@topwealtharena.com.
