Meraydin: Merge Cargo ("the app") is made by Ilya Pavlov, an independent developer. This page says what the app stores on your device, what it sends to our server, to Google and to Amplitude, why, and how to get it removed. It is written to be read, not skimmed past.
The short version
- No account, no email, no password. The app makes up an anonymous identifier for you, and you type a short display name for the rankings.
- We store your games: the day's cargo, where you dropped each piece, which Broker deals you picked, and your score. That is what a leaderboard entry is.
- The app uses Google Firebase to count how many people play and to receive crash reports, and Amplitude to see how the game is played. It does not use the advertising identifier and does not track you across other apps or websites.
- No ads. We do not sell player data.
- Settings → YOUR DATA → DELETE erases everything we hold about you on our server, straight away.
On your device
The app keeps your settings, your best scores, your display name, a random identifier it generated on first launch, games that are waiting to be sent, and the names you have reported. Nothing on the device is read except what the app wrote itself. If you reinstall the app, a new identifier is generated and the old anonymous player is not linked to the new one.
On our server
When you play with a network connection, the app sends the following to api.meraydin.com:
- An anonymous player identifier, generated by the app. It is not derived from your device, your Apple ID, or any advertising identifier.
- Your display name, which you type when you first open the app and can change in Settings. It is shown on the rankings to everyone. It is 2 to 8 letters or digits and is checked against a list of words that are not allowed. If you do not choose one, the server picks a name for you. Other players can report a name they find offensive; see Reports.
- Your games: the date and seed of the cargo, the position and timing of every drop, the Broker deals you chose, the final score, and how long the game lasted. The server uses them to judge whether a score is one the game could plausibly produce.
- Which platform and app version you are on, and the dates on which you opened the app. We use this to count how many people play each day and to find bugs in a particular version.
The server sits behind Cloudflare, Inc., which routes traffic to it and, as any network provider does, sees your IP address while doing so. We do not store IP addresses with your player data.
Google Firebase
The app includes two Google services: Google Analytics for Firebase, which tells us how many people play and how often they come back, and Firebase Crashlytics, which tells us when and where the app crashes. They collect:
- an identifier for this installation of the app, generated on your device;
- how the app is used: when it is opened, how long a session lasts, which version you have;
- your device model, iOS version and language;
- an approximate location, at the level of a country or city, which Google works out from your IP address — the app never asks for or reads your location;
- when the app crashes, the technical details of the crash and the state of the device at that moment.
Firebase does not receive your display name, your games or your player identifier: the app sends nothing to Google that identifies you. Crash reports are kept for 90 days. Google processes this data for us under its own terms and privacy policy, policies.google.com/privacy, and may process it on servers outside your country.
Amplitude
The app sends how the game is played to Amplitude, Inc., a product analytics service, so we can see which parts work: when a game starts and ends, its score and length, how many pieces were dropped and merged, which Broker deals were offered and which one you took, which screens you open, and whether a score reached the server. With it go a random identifier the app makes for Amplitude, your anonymous player identifier from our server, the app version, your device model, iOS version and language, and an approximate location at the level of a country or city, which Amplitude works out from your IP address.
Amplitude never receives your display name. It stores this data in the United States and processes it for us under its own terms and privacy policy, amplitude.com/privacy. Because it is tied to your anonymous player, deleting your data in Settings deletes it at Amplitude too.
Reports
If a name on the rankings is offensive, you can report it from the Rankings screen. The name is hidden on your device at once. The server records which player reported which name, and when. We read reports, change names that break the rules, and can ban a player from the rankings. A name that several players report is replaced with a name picked by the server before anyone has read the reports. Reports are deleted when either player deletes their data.
What we do not collect
Your real name, email address, phone number, contacts, photos, precise location, the advertising identifier, or anything typed into other apps. The app shows no advertising. We do not sell player data, and we do not share it with anyone except the three service providers named on this page, Cloudflare, Google and Amplitude, for the purposes described here.
Why we keep it
To run the daily rankings and keep them fair, to keep offensive names off them, to fix bugs and crashes, and to look at aggregate numbers such as how many games were played on a given day or which deals get picked most. Where the law asks for a basis, ours is our legitimate interest in running a working, fair game. Runs stay on the server for as long as the rankings exist, because a leaderboard whose history is deleted stops being one — unless you delete them yourself.
Children
The app is a puzzle game for a general audience and is not directed at children under 13. It asks no one for personal information, has no chat, and has no purchases. The only thing a player types is the short display name described above. If you are a parent and want your child's data removed, use the button below on their device or email us.
Deleting your data
Settings → YOUR DATA → DELETE erases your anonymous player, every game you submitted, your launch history and the reports you made or received from the server straight away, drops you off every leaderboard, and asks Amplitude to delete what it holds about your player. It cannot be undone, and the app then treats the device as new.
Deleting the app removes everything stored on the device, but not what is already on the server, so use the button first if you want both gone. If you have already deleted the app, email [email protected] with the display name shown on your rankings row and we will remove it within 30 days and confirm by reply. You can also write to ask what we hold about you, to correct it, or to object to its use.
Analytics and crash data held by Google are not linked to your player, so they cannot be looked up by name; they expire on Google's schedule.
Changes
If the app ever adds a feature that changes what it collects, for instance signing in with Game Center to see friends, this page will be updated before that feature ships, and the date at the top will change.
