Ouk Chaktrang (អុកចត្រង្គ) — Khmer Chess
Ouk Chaktrang is a free game. It is paid for by advertising. This page explains what the game does with information, in plain language.
You can play the whole game — against the computer, puzzles, lessons, and two players on one phone — without signing in and without an account.
What stays on your phone
These never leave your device. They are stored by the app and removed when you uninstall it.
- The name you choose for yourself, and your chosen avatar piece and colour.
- A picture you import as an avatar, if you choose one. It is resized and saved on your phone. The original is not kept, and the picture is never uploaded anywhere.
- Your settings — language, theme, board, sound, and so on.
- Your own win and loss record.
If you sign in with Apple or Google
Signing in is optional, and only needed if you want your profile to follow you to another device. If you do sign in, Google Firebase gives the game an account identifier, and Apple or Google shares your name and email address with that account (with Sign in with Apple you may choose to hide your email). The game stores your display name, your avatar choice and your record against the account, so it can be restored later. The game never sees or stores your password.
If you play online against other people
Online play sends information through the game's own server so the two phones can see each other's moves. This server runs on Cloudflare.
| What | Why |
|---|---|
| A random player identifier created by the app | So the other phone knows which seat is which. It is not your name, your email or your phone. |
| Your display name | Shown to the person you are playing. A copy is kept if someone adds you as a friend. |
| The moves of the game while it is being played | To pass each move to the other player. |
| The result when a game ends — who won, how it ended, how many moves, and when | For your game history and ratings. |
| Chat messages you send | Passed to the other players. Messages are filtered for offensive words and deleted after 24 hours. |
Blocking and reporting
You can block any player from their player card; the list of people you block stays on your phone. If you report a player, the game sends their name, player identifier and up to their last five chat messages to the developer, who reviews reports and may remove players who break the rules. Reports are kept for moderation for up to 12 months.
Advertising
The game shows a banner advertisement, supplied by Google AdMob. To do this, Google may use your device's advertising identifier and information about ads you were shown. Google's own handling of that information is described in How Google uses information from sites or apps that use our services.
Where the law requires it, you are asked to choose before any personalised advertising is used, and on iPhone and iPad the system also asks whether the app may track you. You can say no. The game works exactly the same either way — you will still see advertisements, but they will be less specific to you.
You can change these choices later in your device settings, and on iPhone and iPad under Settings → Privacy & Security → Tracking.
What the game does not do
- It has no analytics and no crash reporting.
- It does not ask for your phone number or contacts, and it only receives your email address if you choose to sign in.
- It does not upload your photos.
- It does not sell anything, and it does not sell information about you.
Children
The game is suitable for all ages and is not directed at children under 13. It does not knowingly collect information from children.
Removing your information
Uninstalling the app removes everything kept on your phone. If you signed in, you can delete your account and the online profile, friends list and records held against it from inside the app: Profile → Delete account. You can also write to the address below and ask — see how to delete your account.
