Privacy & support
Questions, feedback, privacy requests, or payment support? Email hello@mahjonglobby.com. Please don’t send passwords, card details, or other sensitive information.
Playing and reconnecting
Solo games and preferences are saved in your browser. Multiplayer tables store nicknames, hands, moves, scores, and a random player identifier on our server so people can play together and reconnect. A first-party cookie identifies your player; connection timestamps let us detect disconnections and temporarily provide a bot. Clearing this cookie may prevent you from reclaiming your seat.
Anyone with a table link can view its public activity. Other players’ concealed hands are not included in spectator views. Treat invite links as shareable access links, and use a nickname you are comfortable showing to other players. Multiplayer records currently remain stored until removed by the operator.
Anonymous gameplay measurement
We measure approximate active playtime using a separate random first-party browser cookie. Our usage records are not linked to your nickname or game account and do not contain IP addresses, table codes, hands, or tile choices.
Measurements include a 15-second time bucket, active seconds, and solo or multiplayer mode. Only visible, focused gameplay counts; counting pauses after five minutes without interaction. Duplicate intervals are capped. Offline periods and blocked requests may not be measured. This feature does not create session recordings or advertising profiles.
The private dashboard shows 30 days of aggregates in America/New_York. Usage records older than 90 calendar days are deleted when the owner loads the dashboard, rather than on a fixed daily schedule.
Exclusion applies to this browser’s previous records and future activity. Set it separately on each device. Clearing cookies creates a new identifier and may prevent us from associating previous records with you.
Hosting and website analytics
Cloudflare hosts the site and database. Infrastructure and website analytics services may process request information, including network addresses and browser information, separately from our gameplay measurement. See Cloudflare’s privacy policy.
Feedback and email
Feedback is stored privately with your message, optional contact details, game mode, and submission time until removed by the operator. A daily keyed digest of your network address helps limit spam; raw IP addresses are not stored in feedback records. Email correspondence is also used to respond to support requests.
Optional financial support
Mahjong Lobby is free to play. Any contribution offered through the support panel is optional, one-time support—not a subscription or a purchase of future Pro access. When Stripe checkout is available, Stripe handles payment information on its own page; do not send card details to us. For payment questions or refund requests, email hello@mahjonglobby.com with your receipt reference. See Stripe’s privacy policy.
Privacy requests
Contact hello@mahjonglobby.com to ask about access, correction, or deletion. Include only enough context to locate the relevant feedback or game. Some browser-only records cannot be identified after cookies are cleared. Payment or operational records may need to be retained where required.
