Catastrochess is a chess game with cats. This page explains what data the game uses, what for, and how you can delete it. In short: offline, the game only sends a technical report when it crashes; ads are shown by Google AdMob; and online mode keeps on a server only what is needed to play with other people.
Playing offline
Playing against the computer, two players on one phone, the daily puzzle, daily missions, lessons, the gallery, the wardrobe, the shop and the settings all work without internet. Your settings, your cookies and what you buy with them, your achievements, your streaks, your missions, the lessons you finished, the players you reported and an unfinished game are kept only on your phone and are deleted when you uninstall the game.
Reminders
If you allow it, the game schedules a daily notification on your phone to remind you of the puzzle and your streak. It is scheduled and shown on the phone itself: nothing is sent to any server. You can turn it off in Android's notification settings.
Crash reports
If the game closes because of an error or freezes, it sends a report to Firebase Crashlytics, a Google service, so we can find and fix the problem. The report contains the technical log of the error, the phone model, the Android version, the game version and a randomly generated installation ID that cannot tell who you are. To work out how often the game runs without crashing, it also notes when it is opened. It does not include your name, your email, your location or anything you do in your games. Google keeps reports for 90 days.
Ads
The game shows Google AdMob ads, a Google service, at these moments and no others:
- When a game ends (not after a puzzle or a lesson), a full-screen ad. Never before or during a game.
- When you ask for it: in the shop, an ad to earn cookies, and during a game, an ad for 3 more hints.
To show them, AdMob uses the phone's advertising ID and technical device data, and may use them to choose the ad. If you live in the European Economic Area, the United Kingdom or Switzerland, the game asks for your consent first, and you can change it at any time in Settings › Game › Ad privacy. You can reset or turn off the advertising ID in your phone's Google settings. Ads are limited to content suitable for all audiences. More information: how Google uses data in advertising.
Purchases
You can buy cookie packs with real money. Payment is handled by Google Play: the game never sees or stores your payment details. When you buy, Google Play gives the game a signed receipt with the product, the date, the order number, a purchase code and an anonymous code for your online account (a hashed digest of its ID, not your name or email). The game keeps that receipt in your online account (a guest account is made if you have none) so it can give your cookies back on another phone if you sign in with your Google account. Only you can read your receipts.
Playing online
Opening "Play online" creates an anonymous guest account without asking for any data. If you want, you can link it to your Google account to keep your profile when you change phones. Online mode stores this data in Firebase, a Google service:
| Data | What for | Who sees it |
|---|---|---|
| A randomly generated account ID | Knowing which profile is yours. | No one sees it in the game. |
| The name you choose in the game | Showing it to your opponents, your friends and on the leaderboard. | All players. |
| Your wins, losses, draws and points | Showing your record and your place on the leaderboard. | All players. |
| Your friend code | Letting other players add you. | Only people you give the code to. |
| Your friends list and pending challenges | Challenging your friends. | You; each friend sees they have you added. |
| When you were last online | Showing your friends whether you are online. | Your friends. |
| The moves of your online games, clock times and each player's name | Letting both players see the same game. | Your opponent. |
| The cats you dressed in the wardrobe | Letting your opponent see your cats in the game. | Your opponent. |
| The last gesture you sent in each game ("Meow!", "Good game!"…) | Letting your opponent see it. | Your opponent. |
| The last written message you sent in each game | Letting your opponent read it. Each player chooses in Settings whether to see the chat and whether rude words are covered. | Your opponent. |
| The last voice message you sent in each game (up to 5 seconds, recorded only while you hold the button) | Letting your opponent hear it. It is deleted when you leave the game. The game uses the microphone only while you hold the button, and you can turn voice messages off in Settings. | Your opponent. |
| The designs you saved in the wardrobe | Giving them back on another phone. | Only you. |
| The receipts of the cookie packs you bought (see Purchases) | Giving your cookies back on another phone. | Only you. |
| Names you report: the reported player's ID and name, your ID and the date | Reviewing offensive names. | Only us. |
| Your Google email, only if you link your Google account | Signing in with Google. It is kept by Firebase's sign-in service. | No one in the game. |
App check. To protect online mode from modified versions of the game, when you connect the game asks Google Play to confirm that it is the original version installed from Google Play on a real device (Firebase App Check with the Play Integrity API). Google processes technical device and app data for this; we only learn whether the check passed.
Names, chat and reports. Online games have short written messages and voice messages; both can be turned off in Settings, and a blocked player's are never shown or played. Offensive names are filtered, and you can tap a name on the leaderboard or in your friends list to report it: you will stop seeing their name and challenges, and we will review it. We may replace an offensive name with a neutral one.
Apart from the ads described above, the game uses no tracking tools, and it does not sell or share data with anyone beyond Google as the provider of the server, crash reports, app checks, ads, updates and payments. Data travels encrypted over the internet.
How long data is kept
As long as you have an online account. Deleting it removes your profile (with your purchase receipts: cookies already on your phone stay), your code, your friendships, your challenges, your leaderboard place and your sign-in account, and your name is replaced by "Deleted player" in the games you played. Reports are deleted once we finish reviewing them.
How to delete your account and data
In the game: Play online → Delete my account, and confirm. You can also ask without the game, as explained in Delete your account (in Spanish; write to us in English if you prefer).
Children
The game's content is suitable for all ages, but the game is not directed at children under 13 and does not knowingly collect personal data from them. Online mode has written and voice messages between the two players of a game, which can be turned off in Settings. If you are a parent or guardian and believe a child has created an account, you can delete it as explained above or write to us.
Changes and contact
If this policy changes, this page and its date will be updated. For any question about your data, write to melendezyamil390@gmail.com.
