Back to Stone Collection MythPrivacy Policy
Version 2.0 · In effect from November 2, 2026
Last Myth Studios makes Stone Collection Myth, a puzzle adventure for all ages on Android, iPhone and iPad. This policy covers the game. Our website and other games follow the studio policy at lastmythstudios.com/privacy. Questions: hello@lastmythstudios.com.
Levels, stars, scores, crystals, achievements, settings, language and the name chosen for the Hall Board are saved on the device. So is a local record of how each level went (tries, time, hints). We don't receive any of it. The exceptions are in sections 4 and 10: players who join the Hall Board send their nickname and ranking numbers, and achievements and scores also go to Game Center or Google Play Games when the player is signed in.
Options → "Erase progress" deletes the progress and the local record (settings stay) and takes the player off the Hall Board. Uninstalling the game deletes everything.
When "Game stats" is on in Options (it starts on), the game sends our server how the levels were played:
• which level and puzzle, the result (won, lost, left or restarted), stars, score, moves, time played, hints and undos used, and the try number;
• how long each session lasted, how far the story has gone, and whether story scenes were watched or skipped;
• the game version, the language and the system (Android or iOS).
These events carry a random code that the game creates on this installation (for example, i-7F3KQ2…), so we can see how a player progresses over time. The code is not the device ID or the advertising ID, other apps can't see it, and it disappears when the game is uninstalled.
We use these stats only to balance the difficulty of the levels and to improve the game. They are not used for advertising, for profiles, or to follow anyone across other apps or websites.
Turning "Game stats" off stops the sending right away, deletes whatever was still waiting on the device and throws the code away. If it is turned on again, the game makes a new code with no link to the old one. "Erase progress" also replaces the code.
Without an internet connection, the stats wait on the device for at most 30 days (up to 1,000 events) and are sent later.
The Hall Board is the game's ranking, with boards for level progress, stars, achievements, points and one for each free-play game. It starts off: only players who choose a nickname and tap "Join the Board" are on it. The nickname window appears the first time a player opens the Board, and "Cancel" keeps the player off it.
The game suggests a nickname (such as "FrostRunner"), and the player can replace it with one they type, with 2 to 20 letters or numbers. The game asks players not to use their real name, and our server rejects swear words and long runs of numbers, such as a phone number. There are no messages or any other way for players to talk to each other.
Tapping another player's nickname lets you report or block it. A report sends us the reported nickname, the reason (optional, written by the person reporting), the board and position, the game version and the system. It reaches the studio team by email, and we review it and remove offensive nicknames or nicknames with personal details from the Board. Blocking hides the nickname on that device only and can be undone.
Players on the Board send our server: that nickname, a random code just for the Board (different from the stats code), the levels won, stars, points, number of achievements, the records for each free-play game (level, stars, the game's own measure and time), the game version, the language and the system. This happens after wins and when the Board is opened.
Other players see only the nickname, the position and those numbers. The code, the language and the system are never shown to anyone.
"Leave the Board", on the Board screen, deletes right away everything the Board kept for that player and replaces the code. "Erase progress" does the same (without internet, the leaving is noted and happens on the next connection). Players who send nothing for 24 months are taken off the Board automatically.
The Board doesn't depend on the game stats: a player can be on the Board with stats turned off, and the other way round.
Name, email, phone number, address, photos, voice, contacts, location, date of birth, the advertising ID (IDFA or Android advertising ID) or hardware IDs (such as the Android ID, IDFV, IMEI or serial number). There is no chat. Of what is typed in the game, only the nickname of players who join the Board and the reason given in a report reach us. The only thing one player can see of another is the Hall Board nickname and their numbers, and only if that player joined the Board.
Like every internet connection, our server sees the IP address that sends the stats or the Board scores. We use it only in memory to stop abuse (a limit of sends per minute) and we don't store it.
The game currently has no ads. Future versions may include ads; if that happens, we will update these terms and the privacy policy and ask you to review and accept the new version in the game before continuing.
Any ads shown to children would come only from ad networks allowed by the app stores' family rules, without personalized ads.
There are no in-game purchases, coins to buy or loot boxes. If the game is sold for a price, the app store handles the payment under its own rules, and we never receive payment details.
On phones and tablets the game can schedule a few local reminders (three at most, never at night), only if the player says yes when the game asks and the system allows it. They are created on the device itself, and no data leaves it for this. They can be turned off in Options or in the system settings.
The game can open the store pages of other Last Myth Studios games and these legal pages. Those buttons work only after being pressed and held for 3 seconds, so a young child doesn't leave the game by accident. Outside the game, the policy of that website or store applies.
Google Play and the App Store handle downloads and updates under their own policies. The store may show its own rating request; we don't see who rated.
If the device is signed in to Game Center (iPhone and iPad) or Google Play Games (Android), the system may show its own sign-in banner, and the game sends that service the achievements earned and the scores for its leaderboards (such as the furthest level reached and the total stars). The service shows them on the player's own profile and leaderboards, under its own privacy policy and the visibility the player chose there. The game doesn't send the Hall Board name to those services, and we don't receive or store the player's Apple or Google account data. Without signing in, nothing is sent to those services.
The game is made with the Unity engine. Unity Technologies may receive basic technical information about the device, such as the model, the system version and the graphics chip, under its own privacy policy. We don't receive it.
Stone Collection Myth is made for everyone, including children, so it collects as little as it can: no account, no contact details, no ads, no chat, stats that can be turned off at any time, and an optional ranking where nicknames are filtered and can be reported.
In the United States (COPPA), the game collects only the random codes described above, used solely to support the internal operation of the game (understanding and improving its levels and keeping each player's line on the Hall Board). The Board nickname is chosen by the player, and the game tells players not to use their real name; nicknames with personal details are removed from the Board when we see them or receive a report. We don't use this data to contact anyone, to build profiles or to show ads.
In Brazil (LGPD, art. 14, and the ECA Digital, Law 15.211/2025), in the European Union (GDPR) and in the United Kingdom (Age Appropriate Design Code), we process the stats and the Hall Board in the best interest of children, on the basis of our legitimate interest in making a game that is fair and fun, and we offer a simple way to stop both. The Board is only turned on when the player chooses to join.
Parents and guardians can turn the stats off in Options and take the player off the Board at any time and can write to hello@lastmythstudios.com to ask what we hold or to have it deleted.
The stats and the Board scores travel over an encrypted connection (HTTPS) to our server, hosted by Vercel, and are stored in our database at Supabase, in tables that only our server can access (from the Board, other players receive only the nickname, the position and the numbers). These providers act on our instructions and may process data in the United States and the European Union, with standard contractual safeguards. We don't share data with advertisers or data brokers.
We keep the stats for up to 24 months and then delete them. Board scores stay while the player is on the Board and are deleted after 24 months without a send.
In the game: turn "Game stats" off in Options to stop the sending and throw the code away; "Leave the Board" deletes the Board nickname and numbers on our server right away; "Erase progress" deletes the progress on the device and also takes the player off the Board; uninstalling deletes everything on the device.
To see or delete stats that were already sent, write to hello@lastmythstudios.com with the stats code shown in Options → Privacy Policy. Since we don't know who the players are, the code is the only way to find their data. Once stats are turned off, the old code is no longer linked to the device, and its data is deleted when the 24 months are up. To take someone off the Board without the game, write with the name and position shown on the Board.
You can ask for access, correction, export or deletion, or object to the use of the data. In Brazil you can also contact the ANPD; in the EU and the UK, your data protection authority.
The game never talks to the database directly. Only our server can, with a key that stays on the server. Every event and every score is checked and limited in size (impossible scores are refused), and we keep only what is needed to improve the game and run the Board.
Each version has a number and a date, shown at the top. If a change affects how data is used (for example, if ads are added), we will publish the new version here first, and the game will show it and ask for it to be accepted before play continues. Small fixes, such as a typo or a new contact address, are published here without a new acceptance.
