Your game
stays yours

This covers the My Mahj Lab app for iPhone, iPad, and Android, and the My Mahj Lab games here on the website: the Daily Mahj Puzzle, Learn to Play, Quick Practice, Play a Full Game, playing with friends, groups, and the Glossary.

• There is no account and no sign in. My Mahj Lab never needs your name, email, or location. You only share a name or an email if you choose to, in the ways listed below.
• Your progress, your streak and badges, your tile style, any hands you type in, and your settings are saved only on your own device. They are never sent to me or to anyone else, unless you join a group, sit down at a table with friends, or finish the Game of the Day (see winning hands below).
• Groups are your choice. If you start or join a group, the name you type (a first name or nickname is perfect) and your results for the Daily Mahj Puzzle and the Game of the Day are saved on this website so your group can see them on its scoreboard. Only people with your group's code can see them. Tap Leave this group any time to take your name off the scoreboard, or email me and I'll delete it for you.
• The top players boards are your choice. If you add your name to a board, that name, your result (moves or points, turns, and time), and how many days in a row you've played are shown to everyone on that day's board and on the weekly leaderboard, and the top players of each week and each tournament week are shown on the website. You can take your name off any day's board, and on My Mahj Lab you can turn off adding your name on its own.
• Winning hands: when you finish the Game of the Day, your result (won, lost, or wall game) is saved on this website with no name, along with the tiles of your winning hand if you won. That's what lets you see the day's winning hands once you've played. Players who have finished that day's game can see which hands won and how many people won with each one. If your name is on the board, they can also tap your name to see the tiles you won with. People who haven't played that day can't see any of it.
• If you challenge a friend, the name you type and your result are saved with your challenge link. Anyone with the link can see them, along with the names and results of the friends who took the challenge.
• The Daily Mahj Puzzle email is your choice. If you ask for it, I receive your first name and email. They're kept privately on this website and with Resend, the company that sends the emails. I use them only to send the puzzle each morning, and news about new printables and classes if you check that box. Every email has an unsubscribe link, and I never sell or share your email.
• Tournaments are your choice. To play in one, you sign up with a name and your email, and I email you a code to confirm it's you. Your name, your tournament points, how long each tournament game took, and the hands you won with are shown to everyone on the tournament board (a day's hands only to people who have played that day's tournament game, or once the day is over). Your email is kept privately on this website and with Resend, the company that sends my emails, and is never shown on the website. I use it to send your code, to email you about the tournament (like when it starts and who won), and to send the winner their prize. The phone or computer you sign up on is linked to your sign-up so your games count, and every email has an unsubscribe link. You can leave a tournament any time on the Tournament page, or email me and I'll delete your sign-up.
• Playing with friends is your choice too. When you make or join a table, the name you type is shown to the other players at that table, and the game you're playing is kept on this website while you play. That's what lets everyone play from their own phone, and it's how each player sees only their own tiles. Only people with your table's code can join. There is no chat, so the other players only ever see your name and your moves. Tables are deleted on their own when everyone leaves, or two days after they were made.
• My Mahj Lab has no ads and no tracking. Here on the website, I count how many people play each game, using a random number your browser makes up. There are no names and no cookies, and I can't tell who anyone is. The app doesn't count anything.
• If you turn on the daily puzzle reminder in the app, your phone schedules it on its own. Nothing is sent anywhere.
• When you tap Share, your phone's share sheet opens and you choose where your result goes. When you copy a share code for your group, it stays on your clipboard until you paste it.
• Links to this website open in your phone's browser, where the website part of this page applies.
• Deleting the app deletes everything it saved on your device. If you were in a group, leave the group first to take your name off its scoreboard, or email me and I'll do it.

My Mahj Lab is made for players of all ages, including families who play together. It never needs anyone's real name, email, or location. If kids join a group, a table with friends, or a top players board, a nickname works just as well as a name. The Daily Mahj Puzzle email is meant for grown-ups.

If any of this ever changes, I'll update this page before it happens and change the date at the bottom.
