Applies to: the WeChat mini-game and Android and iOS editions of WordCrate: Word Sort Puzzle (英语单词收纳盒). Last updated: November 9, 2026.
The game is provided by makemori (森造). For privacy questions or requests, contact [email protected]. Information handling differs between platforms; please read the sections for the edition you use.
This policy does not cover development or playtesting tools, editions on other platforms, or browsing the makemori website alone. The website privacy notice explains information handling when you visit this page or the website.
A quick look at each edition
- WeChat mini-game: includes advertising, sharing and limited usage statistics, as explained below.
- Android and iOS: currently have no ads or in-app purchases and do not send gameplay data to analytics services. Core play works offline.
- Settings and learning records: stay on the device you use. We currently provide no cloud saves or cross-device syncing.
Visiting webpages or emailing support also involves the relevant services, as explained under “Websites, support email and recipients” below.
Settings and learning records on your device
The game uses local storage to remember your choices, continue progress and organise review:
- Settings and guidance: sound, music, volume, vibration preferences, interface language, meaning assistance, automatic pronunciation, hints and tutorial completion. Availability depends on the platform.
- Learning and game progress: main-level progress, completion records, learned words, practice answers and results, familiarity, review dates and counts, unfinished reviews, important-word marks, word-cabinet achievements and word-search records.
- Helpers: item balances and claims, ad or share unlocks and their expiry, daily share counts, and records that prevent duplicate rewards or recover interrupted operations.
These records stay in the mini-game or app storage on your current device. The game has no developer-operated player account or cloud-save service and does not automatically upload a complete save or individual answers to us. The WeChat edition separately sends the limited usage statistics described below. Local learning records do not mean that WeChat itself processes no usage information.
The game reads information such as system language, screen dimensions and safe areas to choose a language, lay out the interface and adapt to the device. Listening exercises play audio supplied by the game; they do not record your microphone.
WeChat login, advertising, sharing and statistics
Platform login. At startup, the WeChat edition obtains a temporary login code from WeChat. We do not use it to create our own player account, save it, send it to our own server or use it in usage statistics. The game does not actively read your WeChat account identifiers (OpenID or UnionID), nickname, avatar, phone number or contacts. WeChat’s own handling needed to run mini-games remains subject to its platform policies.
Advertising. The WeChat edition uses WeChat rewarded video, interstitial and banner ads. Some helpers let you choose to watch an ad; the game checks whether viewing was completed before deciding whether to grant the reward. Interstitials and banners can also appear on relevant screens or between levels, so not every ad starts from a reward button.
WeChat advertising services handle loading, display, clicks, measurement and security checks. This may involve device and network information, platform identifiers and ad interactions. The game does not actively read your advertising identifier to display ads or attach complete learning saves to ad calls. See the Weixin Privacy Protection Guidelines and WeChat’s privacy and advertising settings for platform data use, personalised advertising and available controls.
Sharing. You can choose to share a game card through WeChat. WeChat handles the recipients and sharing action you choose; the game does not read chats or your friend list. It may keep local share counts and helper unlocks. Starting a share does not tell us that a message has been read.
WeChat platform statistics. The WeChat edition sends limited game-usage statistics to WeChat. Examples include startup, error categories, sharing actions, and selected gameplay and rewarded-ad activity. We use these statistics to understand feature use, find problems and improve the game. The information sent is limited to predefined categories, counts or ranges. It excludes login credentials, platform account identifiers, contact details, individual answers, text you enter yourself and detailed technical error information. For these WeChat statistics, the game does not create an extra ID for you or for each time you play.
WeChat receives these statistics and may process them with account, device and service information it holds under its own policies. WeChat’s policies govern retention and privacy controls for its records.
Analytics managed by makemori. In WeChat versions where our analytics is enabled, we send limited gameplay records to a service we manage to understand how players use the game and improve levels and features. These records include level progress, review completion, use of features such as word search and the Word Pond, and use of rewarded ads and in-game rewards. The records include the game version, the time of the activity and a randomly generated installation ID that lets us group gameplay from the same installation. We process this information only as needed to understand and improve the game experience.
WeChat needs network access to open the mini-game, obtain game packages, show ads, share and provide platform services. Levels, vocabulary and audio are supplied with the current game; it does not use our cloud-save or online level-update services.
Differences in the Android and iOS editions
The current Android and iOS editions have no advertising, in-app purchases or social sharing, do not send gameplay data to analytics services, and have no game account or cloud saves. The WeChat advertising, login and analytics practices above do not apply to these editions. Game content and audio are supplied with the app, and core play works offline.
The native editions do not request contacts, camera, microphone, precise location or photo-library permissions, or require a name, phone number or identity document. Android retains Internet permission; this does not itself upload saves or device information. Opening policy webpages, downloading store updates or sending support email involves the relevant network and platform services.
Websites, support email and recipients
Opening a policy or support page connects your browser to the website. Delivery and security services may process IP addresses, visit times and browser information. This site uses Cloudflare, and the public website also uses Google Analytics. See the website privacy notice, Cloudflare privacy policy and Google privacy policy for details and controls. Disabled game analytics does not mean a website visit has no website analytics.
If you email support, we receive your address, message and any attachments you choose to include. We use them to reply, investigate problems and handle privacy requests. Device model, system or WeChat version, current level and screenshots can help, but you choose what to provide. Hide personal details first and do not send passwords, verification codes or identity documents. Support is optional and does not enable ongoing collection of device information or learning progress.
WeChat and its advertising and reporting services receive the relevant information needed for the WeChat edition; email providers deliver and manage correspondence; website providers handle page visits. App stores, operating systems and device-backup services you enable operate under their own policies. The current native game does not integrate advertising or analytics services to transmit player data to them. We do not sell or rent players’ personal information or use support messages for advertising. We limit access to support information to what is needed to handle the request and may disclose information we actually hold when legally required.
Retention, backups and security
Local saves remain until reset, cleared or replaced. We have no cloud copy and cannot remotely retrieve or restore them. Progress transfer between devices is not guaranteed. The current Android edition does not enable app cloud backup or device-transfer backup; manufacturer and operating-system behaviour may vary. iOS system backups and WeChat storage retention depend on their platforms and your settings.
Local storage relies on platform or operating-system access controls, without an additional save-file encryption layer or in-game password. Protect access to your device with a device lock. Native game policy links use HTTPS without attaching progress or player identifiers; the current Android edition blocks unencrypted network connections. Ordinary email is not guaranteed to be end-to-end encrypted, and no storage or transmission method guarantees absolute security.
We keep support correspondence only as needed to answer and resolve requests and meet necessary legal obligations. We delete the relevant information we hold when it is no longer needed or a verified deletion request can be fulfilled. If we must legally retain some information, we explain why. WeChat advertising and reporting, website, email and backup providers retain their records under their own rules; clearing local saves does not delete records they independently hold.
Access, correction, deletion and withdrawal
You can change preferences in Settings and use “Reset learning progress” to clear learning records such as main progress and reviews. This cannot be undone. It preserves non-learning records such as sound and meaning-assistance settings, item balances and claims, and daily share counts; it does not clear all data.
For fuller local-data removal, Android provides system “Clear storage”. On iOS, use “Delete App”; offloading while keeping data does not have the same effect. For WeChat, use its mini-game data or storage-management controls. Removing a game from recently used entries alone does not guarantee save deletion. Platform interfaces and options can change; contact us if you cannot find the relevant controls. Clearing storage can permanently remove learning progress and item unlocks. Manage system backups separately.
There is no developer-operated game account to close. Clearing local saves affects the saves on your device. WeChat manages the records it holds independently. You can use the contact method below to request deletion of analytics records or support correspondence held by makemori.
To access, correct, copy or delete information we hold about you, or withdraw consent for processing that relies on it, email [email protected] and describe the information and request. You may use “WordCrate privacy request” as the subject. You can contact us with any subject and without installing the game. We may ask for information we need to verify your request. Please do not send identity documents unprompted.
You can choose not to use optional sharing or ad rewards and manage available platform choices in WeChat’s privacy and advertising settings. The current WeChat edition has no in-game option to turn off usage statistics. Skipping rewarded ads or changing platform advertising settings should not be taken to mean that the game-usage statistics described here are turned off. These choices do not erase existing platform records. Stopping play stops new statistics generated by further gameplay.
Withdrawal does not affect earlier lawful processing or necessary legal retention. Reading this policy does not authorise future data uses. Where applicable, you may also request a restriction, object to processing or complain to the relevant authority.
Children and young players
We do not ask children for their names, contact details or identity documents. Users under 14 should use the game with a guardian’s guidance and any necessary consent. WeChat’s rules for minors and advertising apply separately. The WeChat edition includes the advertising and usage reporting described above; guardians should review those practices and manage available platform controls. Guardians can manage local data and contact us about support information a child submitted. If we learn that we hold information about a child that we should not retain, we take appropriate steps such as deletion.
Changes and contact
If we introduce accounts, cloud sync or new advertising services, or change how we handle analytics or other information, we will update this policy and provide applicable notice and necessary consent options. The date above identifies the current policy version.
