Privacy policy: Twenty Eight Express
Last updated 21 October 2026
The short version
Twenty Eight Express has no server and no account. The phones at a table talk to each other directly, over Wi-Fi, Bluetooth or Google Nearby, and a hand of cards exists only on the phones playing it. Nothing about your game is sent to us, because there is nowhere for it to be sent.
The one thing that does leave your phone is what the advertising SDK collects. That section is marked below, and so is the one thing you can choose to send: a picture of a win, if you share it.
What is stored on your device
| What | Why |
|---|---|
| The name you registered | So the other phones can show who is who while a table gathers |
| Your bots' names and their memory dials | So the same bots are there next time you seat one |
| Your table settings | So a table opens the way you last set it |
| A table in progress | So the app can put you back at it if the phone is restarted or the app is killed |
| Bluetooth phones you chose to save | So a phone you joined once is called first the next time. Only a name and an address the platform gave; you can remove them |
All of it stays on the phone, and uninstalling the app removes it. There is no backup to a server, because there is no server.
What leaves your device
To the other phones at your table, and nowhere else: your registered name, the cards the game itself shows everybody, and the moves you make. That is the game being played. It goes over your local Wi-Fi, a direct Bluetooth link, or Google Nearby — never through us.
The host's phone holds the deal, because somebody has to judge a trick. Your own hand is sent only to your phone, and the trump stays face down — on every screen, unread by anybody — until a player asks for it.
To Google, for advertising — the game is free and shows ads:
- an advertising ID
- an approximate location, worked out by Google from your IP address
- device information, and which ads you saw or tapped
That is collected and used by Google AdMob, not by us; we never see it tied to you. Google's privacy policy and its partner terms describe what it does with it.
Sharing a win
When a game is won, the winning screen has a Share button. It makes a picture of that screen in the app's temporary storage and hands it, with a line of words and a link to the game's page in Google Play, to Android's share sheet. You choose where it goes — a message, a social network, nowhere. The app does not send it anywhere itself, does not ask for access to your files or contacts to do it, and never sees whom you picked. The picture is replaced the next time you share and is cleared by Android when it needs the room.
Consent, and how to change your mind
Where consent is required — the EEA, the UK, Switzerland, and the US states with their own rules — the app asks before any ad is requested, through Google's consent tool, and the advertising SDK is not started until you have answered. You can change your answer at any time: Settings → Privacy choices.
Permissions, and exactly what each is for
| Permission | What it is for | If you refuse |
|---|---|---|
| Nearby devices / Bluetooth (connect, scan, advertise) | Finding the phone next to you and holding the link to it | Bluetooth tables cannot be hosted or joined; Wi-Fi and Nearby still work |
| Location, on Android 11 and below only | The platform tied Bluetooth scanning to it on those versions. It is never read, never stored and never sent | Bluetooth discovery cannot run on those versions |
| Wi-Fi state, network state, multicast | Finding tables on the same network, and keeping the link alive when the network changes | Wi-Fi tables cannot be found |
| Internet | The local network, and the advertising SDK | The game still plays over Bluetooth |
| Notifications | The notice shown while a table is running | The table still runs, but Android is likelier to freeze it |
| Foreground service (connected device) | Keeping the table alive while you look at another app. Without it Android freezes the app and the table loses your seat within seconds | — |
| Wake lock | Keeping the link alive during a hand | — |
| Advertising ID | Merged in by the advertising SDK | — |
There is no camera, no microphone, no contacts, no files, no calendar and no precise location anywhere in this app.
Children
This game is not directed at children, though there is nothing in it to protect them from: twenty-eight is a trick-taking game with no stake of any kind. No boot, no chips, no betting, nothing to buy and nothing to cash out.
Your data rights
We hold nothing about you, so there is nothing for us to show you or delete. For what Google holds against your advertising ID, use your phone's advertising settings, where you can also reset or delete the ID.
Changes
If this policy changes, the date at the top changes with it.
