Domino Privacy Policy
Last updated: October 27, 2026
Domino is a tile game made by MightyS. This page explains, for this game only, what leaves your device, what the game server keeps and why. It applies to the apps and to the web version at domino.mightys.dev.
1. Overview
- Domino needs no email, phone number or password. The first time you go online it creates an anonymous account for your device.
- Domino never sells your data. Ads are optional: you see one only when you choose to watch a video or turn on the ad banner. Tracking across other apps happens only if you allow it.
- When there are not enough people online, some seats are filled by computer players. They play by the same rules and are dealt tiles the same way.
- The name you type in your profile and the photo you choose stay on your device. They are never sent to the server or to other players.
2. What leaves your device, and why
| When | What is sent | To whom | Why |
|---|---|---|---|
| When you play online, open the home screen or use Friends | A random device identifier made by the game, and your IP address as part of the connection | The MightyS game server (domino.mightys.dev) | To sign in to your anonymous account, to keep your coins, level and record, and to seat you at a table |
| During an online match | Your moves, the preset reactions you send, and the table you joined | The MightyS game server | To play the match and settle it. Reactions are chosen from a fixed list, never free text |
| When you report or mute another player | The seat you chose and the reason you picked | The MightyS game server | To keep tables respectful |
| When the game opens, when you finish a match, when you open a friend's link and when you share the game | A short anonymous signal: that it happened, the kind of match (practice or online, two or four seats) and the result. No name, no account id | TelemetryDeck | To count how many people play and how many matches are played, without knowing who you are |
| Only when you choose to watch an ad video or turn on the ad banner | Your device's advertising identifier (only if you allow tracking), your IP address, device and app information, and how you interacted with the ad. In the EEA, the UK and Switzerland you are asked for consent first. | Google AdMob | To show the ad and give you the coins it pays, and to measure and limit ads. Ads are personalised only with your consent. |
| When you share the game or invite a friend | The link, through your device's own share sheet | The app you choose to send it with | You chose to send it |
| When you open a link (Privacy, Terms, Contact) | The link opens in your browser | That website | You chose to open it |
The web version. It keeps the same few things in your browser's own storage (your device identifier, your name, your settings) and talks to the same server. Clearing your browser data makes you a new player, which is why the game offers a transfer code (see section 5).
3. What the game server keeps
- Your anonymous account: the device identifier and an automatically generated player name, which is what other players see at a table.
- Your coins, level and XP, the record of matches played and won in each format, league points, your weekly board results and your daily missions.
- Your friends list and requests, the players you muted, and reports you filed.
- Your invitation code and who invited you, if anyone did.
- A hidden skill rating used to seat you with fair opponents.
- A transfer code, stored only as a one way hash, while one is active. It works once and expires after 24 hours.
- Daily totals of matches played (no names): how many matches, in which format, and how many seats were filled by computer players.
The game server does not keep your email, phone number, contact list, precise location, photos or advertising identifier. If you choose an ad, the advertising identifier goes only to Google AdMob as described above, never to our server.
4. Third-party services
| Service | What it receives | Its policy |
|---|---|---|
| Google AdMob (Google Mobile Ads) | Only if you choose an ad: the advertising identifier (if you allow tracking), IP address, device and app information, and ad interactions | policies.google.com/technologies/partner-sites |
| TelemetryDeck | The anonymous signals listed above, with a random identifier that is not linked to your account | telemetrydeck.com/privacy |
| Hetzner Online GmbH (server hosting) | Everything the game server receives, as the company that rents the server. It does not use it for its own purposes | hetzner.com/legal/privacy-policy |
5. Your rights (GDPR, UK GDPR, CCPA)
You can delete your data yourself, inside the game. Open Settings and scroll to the end: Delete my account removes your account, coins, record, friends and name from the server and from this device. This cannot be undone, and it is refused while you sit at a table with coins in play.
To keep your coins and level on a new phone, open Settings, then Move to a new phone on the old one to get a one time code, and enter it on the new one. The code works once, expires after 24 hours, and the old phone stops being your account when it is used. Anyone who holds an active code can move your account to their device, so keep it private.
You also have the right to access, correct, port, restrict and object, to withdraw consent, and to complain to your data protection authority. You can change your ad consent at any time in the game under Settings, Privacy choices (shown where the law requires it), and on iPhone under Settings, Privacy & Security, Tracking. For any question write to contact@mightys.dev; we answer within 30 days. We do not sell personal information.
6. Children
Domino is not directed at children under 13 (16 in the EEA). We do not knowingly collect personal data from children. Other players can send you only preset reactions, not free text.
7. Retention
- Account data is kept while the account exists and is deleted when you delete the account.
- Reports filed about a player are kept as a moderation record, even after that player deletes their account, so that complaints cannot be erased by deleting the account.
- Server logs that carry an IP address are kept for a short operational period only.
- TelemetryDeck keeps anonymous signals under its own policy.
8. Security
Every connection uses encrypted HTTPS or WSS. A transfer code is stored only as a hash.
9. Changes
If Domino starts sending anything new, this page is updated before that version is released and the date at the top changes.
