Chalke Rummy — Privacy Policy
Last updated: 30 September 2026
This privacy policy describes how the Chalke Rummy app and web game (“the app”) handle your information. The app is developed and published by Chalke Customs (“we”, “us”).
Information we collect
The app does not require an account and does not ask for your email address or contact details. It handles the following:
- Game data on your device. Your settings, your coins and the card backs and felts you own, and a bot game in progress are stored on your device only — we keep no copy of them.
- Online play. If you play online, the app creates a random player id for this install (or this browser) and sends it, with the display name you choose, to our game service. Your display name is shown to the other players at your table, and is screened for offensive language before it is accepted. Our servers keep the tables you sit at (the cards played, the scores, whose turn it is) so a game can continue if you reconnect. On iPhone and Android the app may ask the operating system to confirm it is a genuine copy of the app (App Attest or Play Integrity); that check sends no personal information. The app does not send push notifications.
- Purchases. Coin packs and Remove Ads are bought through the App Store or Google Play, which handle payment; we never see your payment details. The app keeps a record on your device of what was bought.
- Advertising data (iPhone, iPad and Android only). The app shows ads served by Google AdMob. AdMob may collect device identifiers (such as the advertising identifier, where you have allowed tracking), ad-interaction data, your IP address (from which a coarse location may be estimated) and diagnostic data to serve and measure ads. See Google's Privacy Policy and How Google uses advertising data. The web version shows no ads.
App Tracking Transparency
On iPhone and iPad the app asks your permission before tracking. If you choose “Ask App Not to Track”, your advertising identifier is not shared with AdMob and you see non-personalised ads. You can change this at any time in Settings > Privacy & Security > Tracking.
Advertising and consent
Where consent is required (such as the EEA and the UK), the app shows a consent form from Google's User Messaging Platform before any ad is requested. You can decline personalised ads and still play. Ads appear only in the lobbies and occasionally between hands against bots; never during a hand, and never at an online table. Remove Ads turns them off for good.
Children
The app is not directed at children and does not knowingly collect personal information from children.
Data retention and your rights
A game with no real players left in it is closed and removed from our servers within about an hour. A finished game is deleted about an hour after its last player leaves (so the table can deal a rematch until then), and never kept longer than 7 days. Your player id and display name are kept while you play online; to have them deleted, email us your display name and we will remove them. Data handled by Google (AdMob), Apple and Google Play is held under their own policies. You can reset your advertising identifier in your device's settings, and remove all local game data — your coins, card backs, felts and settings — by deleting the app (or clearing the site's data in your browser).
Changes to this policy
If we change how the app handles data, we will update this page and the "Last updated" date above.
