Privacy Policy

1. Developer information

This Policy describes data processing in Alchemy: Create the World for iPhone and iPad (the “Game”). The developer and the person responsible for data processing (the controller) is:

Name

Ilya Manenkov

Country

Kazakhstan

Email

support@nexledger.pro

This address is used for support enquiries and requests relating to personal data.

The Game does not request a year of birth, determine the user's age or store an age group.

2. Data stored on the device

The main game does not require an account. The following data is created and stored only in the device's memory, in the app's data area:

• Game progress — discovered elements, recipes, completed quests and badges, remaining hints, favourites, current level.
• Settings — language, sound, haptics, reduced motion, the way elements are combined and other interface options.
• Installation record — a random installation identifier, the installation date and the number of launches. The identifier is generated by the Game itself on first launch and is not linked to an Apple Account, a device identifier or a tracking identifier.
• Feedback log — a copy of messages sent through “Share your opinion” (section 4).

This data is not transmitted to the developer as such: the Game does not upload the save file or sync it between devices. It may be included in device backups, which the user manages through iOS. The Game does not request an email address or phone number, and does not collect precise location, the address book, calendar data, photos or a list of installed apps. Microphone access is not requested; the camera and the Game Center friends list are covered in section 12.

3. Diagnostics and usage statistics

To find and fix errors, understand where players stop and improve balance, translations and performance, the Game sends technical information to the developer through the Sentry service (section 6). Sending starts after the save file is loaded at launch and runs in the background.

Crash and error reports. When an error occurs or the Game terminates unexpectedly, the following is transmitted: a description of the error and the place in the code where it occurred, the Game's version and build number, device model, iOS version, the Game's language, memory and display information, the game engine version, and the current level and a progress summary (the number of discovered elements, failed attempts and hints).

Statistics of in-game actions. During play, events are recorded with the same progress summary, the launch number, the number of days since installation and the session length:

• session start and end, load time, frame count and rendering stalls, illustration loading speed;
• attempts to combine elements — ingredient identifiers, the result and method (tap or drag), the number of misses and the time since the previous discovery;
• use of hints, level changes, claiming quest rewards;
• opened element cards, adding to favourites, enabling and disabling slots, changing settings;
• moving between screens of the Game and the time spent on them;
• the query entered in the element search and the number of results found.

All events are linked to the installation identifier described in section 2. The developer does not match it to a name, email address, Apple Account or device and cannot identify the user from it. The tracking identifier (IDFA) is not requested or used. The IP address is processed by Sentry's servers to receive the data and is not stored in events as a user attribute: transmission of information that could identify a person is disabled in the settings.

The element search is intended for element names. Please do not enter personal data in the search field or in error reports: this text is transmitted to the developer exactly as the user entered it.

4. Feedback and enquiries

“Share your opinion”. On an element card the user can send a message to the developer: choose the kind of message (bug, duplicate elements, idea, other) and write a comment. Together with the comment, the following is transmitted: the identifier of the element whose card the message was sent from, the current level, the Game's version, language and platform. The message is delivered to the developer through Sentry and is also written to the feedback log on the device. The comment text is written by the user; please do not include a name, contact details or other personal information in it. No reply is sent to such messages: use email for correspondence.

Email. When a user contacts support, the developer receives the sender's email address and information voluntarily included in the enquiry. This information is used to review the request and provide a response.

5. Purposes and legal bases

6. Data recipients

Crash reports, statistics of in-game actions and feedback from the Game are received and stored on the developer's behalf by the Sentry service of Functional Software, Inc. (USA), acting as a data processor:

• Sentry Privacy Policy
• Sentry Data Processing Addendum
• Sentry security measures

Sentry processes the data only to provide the service to the developer and does not use it for its own purposes. Only the developer has access to the data in Sentry.

The Game is distributed through the App Store. Apple may collect its own crash and app usage information in accordance with the iOS “Analytics & Improvements” settings and the Apple Privacy Policy; the developer sees this information only in aggregated form.

Online mode data is stored on the developer's server; sign-in is confirmed by Apple's Game Center, and the app's integrity by the Apple App Attest service. The nickname, avatar, rating and match history are visible to other players (section 12).

The developer does not sell user data, does not share it with third parties for their own purposes and does not integrate other analytics services.

7. International data transfers

Data sent to Sentry is received and stored on Sentry's servers in the European Union region (Germany). Functional Software, Inc. is registered in the United States and may access the data to maintain the service; the transfer is protected by Sentry's data processing addendum, which includes standard contractual clauses. The transfer and protection mechanisms used by Sentry are described in the data processing addendum.

Online mode data (section 12) is stored on the developer's server, which is located in Germany.

The developer is located in Kazakhstan and accesses the data in Sentry from there. Support correspondence is handled by the developer.

8. Data retention

• Game progress, settings, the installation record and the feedback log remain on the device until the Game and its data are deleted. Data may also be included in device backups, which the user manages through iOS.
• Crash reports, statistics and feedback in Sentry are retained for no more than 90 days from receipt and are then deleted automatically. The developer may keep aggregated figures (for example, the share of players reaching a certain number of discoveries) without installation identifiers.
• Support correspondence is retained for as long as necessary to resolve the enquiry and is deleted at the user's request.

Online mode data, including the results of past weeks, is kept for as long as the account exists and is erased when the account is deleted (section 12). The progress of the main game is not uploaded to the server, except for information about discoveries and the list of completed levels used by online mode.

9. Managing your data

Data on the device

Removed together with the Game when its data is deleted through iOS. On reinstallation a new installation identifier is created; earlier diagnostic data is not linked to it.

Diagnostics and statistics

The Game has no separate switch for this: sending technical information is necessary to maintain it. A request to delete data linked to an installation can be sent to the support address. Sending can be stopped completely by deleting the Game.

Feedback from the Game

Messages are sent only when the user chooses to. The copy on the device is removed together with the Game's data; deletion of a message held by the developer is available on request to the support address, stating the date and content of the message.

Online mode account

Turned off and deleted inside the Game: gear → Game Center (section 12).

10. User rights

Depending on applicable law, users may have rights to information about processing and a copy of their data, rectification, erasure, restriction of processing, objection to processing based on legitimate interest, data portability and a complaint to a data protection authority.

Requests can be sent to support@nexledger.pro. A response will be provided within 30 days.

Users delete the online mode account themselves inside the Game (section 12); on request to the support address the developer will do it for them — the player code is needed to find the account. Diagnostic data is not linked to the account, and the developer cannot locate it by name or email address. Data in Sentry is linked only to a random installation identifier; to find it, information that singles out the installation is needed — for example, the date and content of feedback sent from the Game, or the exact time of a crash.

• Local data: removed when the Game and its data are deleted from the device. Backups are managed separately through iOS.
• Diagnostic data and feedback: deletion requests are sent to the support address; the developer deletes the data located in Sentry.
• Support correspondence: deletion requests can be sent to the support email address.

11. Links to third-party resources

Element descriptions may include links to information sources, and the Game's menu includes links to this website. These open only when the user follows a link and confirms it. Data processing on third-party websites is governed by their respective privacy policies.

12. Online mode and account

Online mode is the duel against other players, the rating, friends and challenges. It runs on the developer's server. The main game and the training duel with the coach work without an account and send none of the data listed below.

Sign-in. Online mode signs in with Game Center, an Apple service. The Game does not ask for a password, an email address or a phone number. You can turn Game Center off inside the Game: gear → Game Center → Turn Off Game Center. The rating, friends and challenges are then unavailable until you turn it on again.

What the server receives and keeps:

• your Game Center player identifier, which is valid only for this developer's games and is never shown to other players;
• your Game Center display name (nickname);
• the avatar you picked in the Game from a fixed set;
• your player code: eight characters other players can use to find and add you;
• your rating, wins, losses and draws, and the results of past weeks;
• your match history: level, outcome, number of rounds, what each player merged;
• information about your discoveries in the main game by level (their number and marks of the recipes discovered), your best combo and the list of levels you have completed;
• your friends list: the players you follow in the Game, and which of your Game Center friends also play, the latter only if you allowed it in the iOS prompt;
• the “Do not accept challenges” setting;
• service information about the account: the date it was created and the time of the last sign-in, the Game's version and language, and marks of the developer's letters you have read and the rewards claimed from them;
• app integrity check data (Apple App Attest): the identifier and public key created on the device for this check, the signature counter, the time the key was created and last used, the result of the last check and the link between the key and the account.

The server's technical log contains no player identifiers.

Why. Only to run the mode: to find an opponent, play the match, calculate the rating, show friends and deliver a challenge. This data is not sold, not shared for advertising and not used for tracking.

App integrity check. To protect the rating from fake clients and forged progress, the device confirms through the Apple App Attest service that a request was sent by the genuine, unmodified Game. A key is created on the device for this; the server keeps its identifier, public part and signature counter and uses them to verify the signature when progress is synchronised and an opponent is searched for. The key belongs to the installation of the Game on the device, not to a person. It is not an advertising identifier: it is not used for tracking or advertising.

What other players see. Your nickname, avatar, player code, place and rating, number of discoveries, win statistics, recent matches and whether you are online now. They do not see your Game Center identifier. The Game has no chat or messages between players.

Camera. It is used only by the friend QR scanner, and only after you open it. The image is processed on the device, is not stored and is not sent anywhere. You can also add a friend without the camera, by nickname or code.

Where the data is stored. The online mode server is located in Germany (section 7).

Retention. The data is kept for as long as the account exists. The rating resets every week; the results of past weeks are kept for as long as the account exists and are deleted together with it.

Deleting the account. You can delete the account inside the Game:

1. gear in the top right corner → Game Center — the Game Center window opens;
2. Delete account → turn on “I understand” → Delete forever.

Second path: Rating tab → your avatar → the gear beside the Game Center line → Delete account. Deletion is unavailable only while a duel is being played.

Deleted at once and for good: the server profile, rating and place, weekly results, rating history, your friends list and other players' subscriptions to you, the player code and its card. Your opponents' match history keeps only the result itself, the outcome and the match figures, with no name and no link to you. The result of the integrity check and the link between the App Attest key and the account are deleted together with the account; the key itself (identifier, public part and counter) remains on the server with no link to the account.

Deletion does not affect the progress of the main game on your device or your Game Center account, which belongs to Apple and is managed in iOS Settings. After deletion the Game does not sign in again by itself; if you turn Game Center on again, a new account is created from scratch.

If you cannot delete the account from the Game, write to support@nexledger.pro and include your player code.
