Rummy Privacy Policy
Rummy is a free Android game: the Chilean card game Carioca, played on your own against a bot. It is funded by rewarded ads and optional coin purchases. This policy explains what data the app handles, where it is stored and what data the ad network that serves the ads and Google Play, which processes purchases, handle.
1. Who we are
Rummy is provided by MCBIT, based in Chile. For any privacy question, write to mcbit.app+rummy@gmail.com.
2. Summary
- Rummy does not ask you to sign up or sign in, and has no server of its own: we do not receive any of your data.
- Your settings, the match in progress, your lives, coins and power-ups are stored on your phone. We never receive them and cannot see them (section 3).
- Ads are served by Google AdMob and are shown only when you choose to watch one, in exchange for coins or a life. AdMob collects certain device data to show, measure and protect ads (section 4).
- If you buy coins, the payment is processed by Google Play under its privacy policy; we do not receive your payment details or any data about the purchase (section 5).
- You can delete all your data at any time by clearing the app's data or uninstalling it (section 7).
3. Data the app keeps
This data stays on your device, in the app's private storage:
| Data | What it is used for |
|---|---|
| Game settings: bot speed, hand order, card back, sound, music, vibration, optional rules and the last choice of match type, rounds and difficulty | Making the game work the way you set it up |
| The match in progress | Resuming the match where you left it |
| Lives and their refill clock | Knowing how many lives you have left and when the next one refills |
| Coins | Keeping your coin balance |
| Power-up stock | Knowing how many power-ups of each kind you can use |
- It is never sent to us: the app has no server of its own to send it to.
- It is not encrypted: it is only game choices and progress, with no personal data. It is kept in the app's private storage, which other apps cannot access.
- No backup: the app turns Android backup off. This data is not uploaded to Google's backup and does not move to another phone when you transfer your data: it exists only on the phone you play on.
- Permissions: the app asks for internet access, which it uses solely for ads and Google Play, and permission to make the phone vibrate. The Google SDKs it includes add the permissions they need: the advertising ID and Android's ad APIs (AdMob), the network state and keeping the device awake while ads load (AdMob), and Google Play billing (purchases).
4. Ads: data processed by Google AdMob
Rummy shows rewarded ads from Google AdMob (Google LLC and Google Ireland Limited). An ad is shown only when you choose to watch it to earn coins or a life. The Google Mobile Ads SDK built into the app automatically collects and shares with Google data such as:
- the Android advertising ID and other device and app identifiers;
- the IP address, from which an approximate location is derived (not precise GPS location);
- technical device information (model, operating system, language, network);
- ad interactions (ads viewed and tapped) and diagnostic and performance data.
Google uses this data to show ads, measure their performance, prevent fraud and, where you consent or the law allows, personalise ads to your interests. Google acts under its own policies: the Google Privacy Policy and how Google uses information from apps that use its services.
Your settings, match, lives, coins and power-ups are not shared with Google or advertisers.
Ad controls
- In any country you can reset or delete your advertising ID in Android Settings › Privacy › Ads. Without an ID, ads are no longer personalised.
- More information and controls at Google My Ad Center.
5. In-app purchases: Google Play
You can buy packs of 10, 30 and 100 coins through Google Play Billing. Google processes the payment under the Google Privacy Policy; we never receive your payment details.
- The app checks the purchase signature on your phone, with Google Play's public license key, to confirm the purchase is genuine.
- No server of ours is involved, and nothing about the purchase is sent to us.
6. Legal bases
Where the applicable law requires it (for example the GDPR in Europe), the legal basis is: performing the service you request, for the game data stored on your phone and for delivering the coins you buy; your consent, for personalised ads; and our legitimate interest in funding a free game, for non-personalised ads, their measurement and fraud prevention.
International transfers: Google may process advertising and purchase data on servers outside your country, including outside the European Economic Area, with the safeguards described in its policy (for example, the European Commission's standard contractual clauses).
7. Retention and deletion
- Game data stays on your phone until you delete it. To delete all of it, clear the app's data in Android Settings › Apps › Rummy › Storage or uninstall the app.
- Clearing the data, uninstalling the app or changing phones also loses your coins, lives and power-ups, and we cannot recover them.
- Data processed by Google AdMob and Google Play is retained under Google's policy.
8. Your rights
As we receive no data from you, we hold nothing we could show you, correct or delete: game data is only on your phone and you delete it yourself (section 7). For advertising and purchase data you can exercise your rights with Google through the links in sections 4 and 5. If you have questions, write to mcbit.app+rummy@gmail.com; you may also complain to the data protection authority in your country.
9. Children
Rummy is not directed at children under 13 (or the minimum age set by the law of your country) and does not knowingly collect children's data. If you believe a child has sent us data, write to us and we will delete it.
10. Security
Game data is stored in the device's private storage, which other apps cannot access. It is not encrypted because it contains no personal data. Final security also depends on your phone: use a screen lock.
11. Changes
If we change this policy, we will publish the new version on this page with its effective date.
