For the Cardhouse Android app · Last updated 5 September 2026
Cardhouse has no accounts and no sign-up. It never asks for your name, email, phone number, contacts, photos, location or payment details, and there is no server holding a profile of you. What follows is the full account of the little that does leave your phone, and why.
Your name, portrait, chips and match history live on your phone and are never uploaded. Cardhouse sends anonymous gameplay statistics and crash reports to Google Firebase so we can tell which games people finish and what is broken, and it shows ads through Google AdMob. Nothing is sold to anyone. Deleting the app deletes everything it kept.
All of the following is stored in the app's own private storage on your device. It is not transmitted anywhere, it is not backed up to us, and no one else can read it:
Uninstalling Cardhouse removes all of it. You can also clear match history at any time from Settings → Clear History inside the app.
Cardhouse uses Google Analytics for Firebase and Firebase Crashlytics. Both are operated by Google, and neither receives your name, your portrait or anything you typed into the app.
The app records a short, fixed list of events so we can see which games get finished and which get abandoned halfway through. These are the events, in full:
| Event | What it carries |
|---|---|
| app_open | Nothing beyond the fact that the app was opened |
| match_started | Game, ruleset, difficulty |
| match_completed | Game, ruleset, difficulty, number of rounds, how long it took, how it ended, won or lost |
| match_abandoned | Game, and which round you left on |
| rules_opened / hint_used | Which game |
| daily_bonus_claimed / _doubled | Which day of the streak |
| ad_requested / _shown / _failed | Ad format and where in the app it appeared |
| review_prompt_shown | Nothing further |
There is no event that carries text you entered, and none that identifies you by anything other than the random installation identifier described below.
Firebase attaches its own technical information to those events, which we do not choose and cannot see individually: a randomly generated app instance ID (specific to this installation, not to you, and reset when you uninstall or clear app data), device model, operating system version, app version, language, and an approximate country derived from your IP address. Firebase does not give us your IP address itself.
When the app crashes, Crashlytics sends the stack trace, the device model and OS version, and the state of the app at the moment it failed — for example, which screen you were on. This is what makes a bug fixable rather than a rumour.
Cardhouse shows ads through Google AdMob: a small banner at the top of a game table, a full-screen ad after a match has finished, and optional videos you choose to watch in exchange for chips. Ads are never shown during a hand.
To serve them, the AdMob SDK uses your device's advertising ID, records ad interactions such as views and taps, and infers approximate location from your IP address. Google's own handling of this is described in How Google uses information from sites or apps that use our services.
The chips in Cardhouse are a score. They cannot be purchased, cannot be exchanged for money or anything of value, and cannot be cashed out. Cardhouse takes no payments of any kind and holds no payment information. The games that stake chips simulate gambling; no real gambling takes place and nothing you do in the app can cost you money.
Cardhouse is not directed to children under 13, and we do not knowingly collect information from them. Because some games stake chips on chance, the app is rated for teens and older, and it is not enrolled in Google Play's families programme.
We do not sell your data, and we do not share it with anyone beyond the two Google services named above. There is no advertising network besides AdMob, no analytics provider besides Firebase, no data broker and no third-party SDK gathering anything in the background. The only circumstance in which we would disclose information is if we were legally required to.
Depending on where you live, you may have the right to access, correct or delete information held about you. In practice, most of what Cardhouse holds is already on your own device and under your own control: uninstalling the app erases it, and doing so also disconnects the analytics identifier tied to that installation. For anything else, write to us at the address below and we will act on it.
If this policy changes in a way that affects what is collected, the date at the top of this page changes with it and the updated version is published here before the change ships in an app update.
