Coral Garden is a family-friendly puzzle game, developed by Duong Hoang Son and published on the App Store by Song Long Game Joint Stock Company (Song Long Game JSC), which is the seller shown on the App Store. We care about players' privacy. This policy explains what the game does and does not do with information.
Coral Garden does not ask for, collect, store on our servers or share any personal information. There are no accounts, no logins, no chat, and no way to type a name: nicknames are picked from a fixed list of sea-animal names.
To find levels that are too hard or too long, the game sends anonymous gameplay statistics to our own server (erp-x.com): when a level is started, won (stars and time), lost (how much of the picture was finished), restarted or left, and when a revive or a helper is used, together with the game version and whether the device is Android or iOS. These records are tied only to a random code the game creates when it is first opened. The code is not linked to the device, its advertising identifier, the player or any account, and it changes if the app is reinstalled.
The statistics contain no names, no photos, no pictures the player made, no contacts and no location. Our server does not store IP addresses. The statistics are used only by us, to improve the game; they are never sold, shared or used for advertising or profiling. Records are deleted after 13 months. A parent can stop the statistics at any time by deleting the app, which also deletes its code. Nothing in them identifies a child, and they are used only to support the internal operation of the game, as the U.S. COPPA rule allows.
This version of the game contains no advertising and no third-party analytics or tracking tools (the gameplay statistics above go only to our own server), and it does not use the device's advertising identifier. If a future version adds advertising, we will update this policy and the store privacy labels before that version is released.
When the game starts, it downloads a small file from our website (erp-x.com) to see whether a newer version is required and which optional features (such as friend challenges) are switched on. This request contains no personal information and no player data; like any web request, it reveals the device's IP address to our web server, which we do not use to identify players.
Game progress (unlocked levels, stars, achievements, settings) and levels the player creates are saved only on the device. They are never sent to us (only what is described in the sections above and below is). Deleting the app deletes this data.
If a player chooses a picture to turn into a level, the picture is processed on the device only. It is never uploaded or shared.
The easiest way to challenge a friend is a code of four sea pictures (for example crab, pearl, shell, castle) that the friend taps into their game. To make the code work, the game sends our server (studio.erp-x.com) the challenge itself: the level number (or the player's own drawn picture), the finishing time and stars, the progress over time for the "ghost" race, and a nickname from the fixed list. Nothing else is sent - no install code, no device information - and the server does not keep IP addresses. Each code and its challenge are deleted after 7 days. Pictures made from a photo are never sent: they cannot be shared with a code.
When a friend finishes a challenge from a code, their game tells our server, sending the code and the random install code described under "Anonymous gameplay statistics" (so that each friend counts once). The challenger's game later asks how many friends finished it, to give the challenger a few in-game helpers as thanks. These records are deleted together with the code after 7 days.
We sometimes post gift codes (for example on our Facebook page or Zalo group). When a player types one into the game, the game sends our server (studio.erp-x.com) the code and the random install code, so that each code can be used once per installation; the server answers with the in-game helpers the code gives. Nothing else is sent, and the server does not keep IP addresses. These records are kept only as long as the gift code exists.
The game can show buttons that open our Facebook page or Zalo group in the browser or in those apps. The game sends nothing to them. Facebook and Zalo are separate services with their own privacy policies.
After finishing a level, a player can show a QR code or copy a challenge link for a friend. The link only holds the level number (or the player's own picture), the finishing time and stars, and a nickname from the fixed list. It is made on the device and shared only by the people using it; we do not receive it. The challenge page on our website (erp-x.com) reads the code in the visitor's browser and stores nothing. The game reads the clipboard only when the player taps "Paste" to accept a challenge, and only to find a challenge link there.
Because we do not collect personal information from anyone, we do not knowingly collect personal information from children under 13 (or the equivalent minimum age in their country). We follow the U.S. Children's Online Privacy Protection Act (COPPA).
If we ever change how the game handles information, we will update this page and the date above before the change takes effect.
