Full policy
How Copybook Club handles your data
Copybook Club is a Chinese handwriting worksheet generator and practice app for iPhone and iPad. This policy explains which information stays on your device, which records are synchronized through your private iCloud database, why the app does not use third-party analytics or advertising SDKs, what the developer receives when you send optional Bookshelf feedback or contact support, and how you can control or delete data.
Privacy foundations
Overview and responsible company
You can create Chinese handwriting worksheets, import text from supported files, extract or recognize Chinese characters, use HSK and themed Word Packs, read Bookshelf stories, practise in Ink Rush, export A4 PDFs, and practise with Apple Pencil without creating a separate Copybook Club account.
Worksheet generation and file processing are performed on your device. Copybook Club does not operate its own server for storing worksheet content.
When iCloud is available, Copybook Club automatically uses Apple CloudKit to synchronize saved worksheet records and selected learning and Ink Rush progress through the private iCloud database associated with your Apple ID. The app continues to provide its core features locally when iCloud is unavailable.
Copybook Club is provided by PM EXPERT COMPAMY DOO, Vuka Karadžića br. 5, 81000 Podgorica, Montenegro (“we”, “us”, or the “developer”). We are responsible for the Copybook Club data practices described in this policy.
Where data protection law requires a legal basis, we process information as necessary to provide the app features you request and perform our agreement with you; to pursue our legitimate interests in answering support requests, maintaining reasonable support records, protecting the app and support process, and preventing abuse; and to comply with legal obligations. Where a system permission is involved, you can manage it through the relevant iOS or iPadOS settings.
Information processed on your device
Depending on the features you use, the following information may be processed or stored locally:
- Chinese text that you enter, paste, select, or edit;
- PDFs, photos, images, and DOCX files that you choose to import;
- Chinese text extracted or recognized from imported files or selected images;
- selected Word Packs or Bookshelf words, pinyin, translations, and related worksheet options;
- worksheet settings, including mode, grid, font, character size, repeat count, pinyin, translation, stroke order, and trace or fade settings;
- generated and saved worksheets;
- Apple Pencil handwriting and saved filled practice;
- Ink Rush source preferences, Today’s 5, round results, character-memory and review state, reward eligibility, and related usage counters;
- app preferences, notification settings, learning progress, and purchase-access information.
During Ink Rush, the lines you draw are evaluated on your device. Release builds do not send raw stroke paths to an external analytics service or store them in CloudKit. Only the resulting progress records described below may leave the device through private CloudKit synchronization.
Some of this information is also synchronized through your private iCloud database when iCloud is available, as described in Section 3.
Private iCloud and CloudKit synchronization
Copybook Club uses Apple CloudKit and the private database associated with your iCloud account. Synchronization is enabled automatically when you are signed in to iCloud and the required iCloud services are available. The app does not provide a separate synchronization switch.
Copybook Club does not create a separate account for this feature and does not use CloudKit to request or receive your Apple ID, name, or email address.
Synchronized worksheet records may include:
- worksheet text, characters, words, or selected Word Pack content;
- worksheet mode and settings, including grid, pinyin, translation, font, and layout options;
- the worksheet creation date;
- a complete PDF containing Apple Pencil handwriting, when filled practice has been saved.
Private CloudKit progress records may also include app activity dates, time-zone information, Ink Drop transactions, level and sticker unlocks, app version, and an app-specific device identifier used to merge records across your devices.
Ink Rush synchronization may include internal character and word-context identifiers, review outcomes, correct and total stroke counts, scheduling and difficulty values, due dates, round identifiers and summaries, reward eligibility, and the internal word-context identifiers selected for Today’s 5. It does not include the raw lines you draw.
Your selected Ink Rush source settings, including the active HSK standard and sources you disable, remain on the device where you choose them and are not synchronized through CloudKit.
For a worksheet without saved handwriting, CloudKit stores the worksheet content and settings needed for the app to recreate the worksheet on another device. A clean exported PDF is not uploaded merely because you exported it.
When filled Apple Pencil practice is saved, the synchronized worksheet record may include the complete PDF containing the handwriting.
If you erase and draw again on an existing synchronized worksheet, the newly saved drawing is also synchronized. Copybook Club uses the latest saved drawing version across your synchronized devices.
Other worksheet content, such as its text and settings, cannot be edited in the app after the worksheet is created. Therefore, after creation, saved Apple Pencil handwriting is the worksheet content that may subsequently change and be synchronized again.
Synchronized records remain in the private iCloud area associated with your Apple ID. Copybook Club does not retrieve their contents into developer-controlled systems, does not copy them to Copybook Club servers, and does not use the contents of your private CloudKit records for advertising, analytics, or profiling.
If you are not signed in to iCloud, iCloud is turned off for Copybook Club, the network is unavailable, or the service is temporarily inaccessible, core worksheet, reading, practice, and Ink Rush features continue locally. Private synchronization resumes automatically when iCloud becomes available again.
Apple provides and operates the iCloud and CloudKit infrastructure. Apple’s handling of iCloud data is governed by Apple’s own terms, privacy policy, security practices, account settings, and storage controls.
Worksheets & files
File import and on-device processing
Copybook Club can extract or recognize Chinese text from PDFs, selected photos or images, and DOCX files. When you select an item, the app processes it on your device and places the resulting Chinese text into an editable field.
Imported source files are not uploaded to Copybook Club servers for processing. Copybook Club does not use a third-party OCR service for this feature.
Text extracted from an imported file may later form part of a worksheet record that you save and synchronize through CloudKit. The original imported PDF, photo, image, or DOCX file is not synchronized as part of the worksheet merely because you imported it.
Extraction or recognition results may contain errors. You can review and edit the resulting text before creating a worksheet.
Word Packs, Bookshelf, pinyin, and translations
Copybook Club includes built-in HSK and themed Word Packs. Word Pack content, pinyin, translations, selected words, and related worksheet settings are processed as part of worksheet creation.
Built-in translations do not use an external translation API. Selecting a Word Pack or enabling a translation does not send your activity to a Copybook Club content server.
Bookshelf stories and their built-in language content are provided within the app. Story choices, selected words, pinyin, and translations are processed on your device as you read and prepare worksheet content.
Choosing a story path or selecting a word does not by itself send that activity to the developer. Optional story-format feedback is a separate feature described in Section 10.
When you save a Word Pack worksheet, its selected words, pinyin, translations, and worksheet settings may form part of the worksheet record stored in your private iCloud database.
PDF generation and export
Copybook Club generates A4 PDF worksheets on your device. A PDF may include selected worksheet formatting, fonts, pinyin, translations, stroke order, tracing, fading, and a small “Made by Copybook Club” signature.
After export, you choose where to save, print, share, back up, or move the PDF using Apple system features or another app. Files placed outside Copybook Club are controlled by the destination, your device settings, and any storage or sharing service you select.
Exporting a clean worksheet PDF does not automatically add that exported file to CloudKit. CloudKit worksheet synchronization is described in Section 3.
Apple Pencil practice
On iPad, you can write on a generated worksheet using Apple Pencil. Your handwriting is processed on your device.
You can clear the practice layer without saving it, or save filled practice as part of the worksheet. The original clean worksheet remains separate and can be used again.
When filled practice is saved, the synchronized CloudKit record may include a complete PDF containing your handwriting. Copybook Club does not upload this PDF to its own server.
If you later erase the handwriting, draw again, and save the worksheet, the newly saved version is synchronized and becomes the latest saved drawing used across your devices.
If you separately export or share a filled worksheet, the resulting file is handled by the destination and system service you select.
Progress & device
Learning progress and reward data
Copybook Club records information needed to provide Daily Streak, Ink Drops, levels, sticker rewards, worksheet reward limits, Ink Rush review scheduling, Today’s 5, rewarded-round limits, and related progress features.
Progress records synchronized through your private iCloud database may include:
- the type of an eligible app activity and its date and time;
- the time zone associated with the activity;
- Ink Drop awards, including award type, amount, and date;
- unlocked level numbers and unlock dates;
- unlocked sticker identifiers, associated levels, and unlock dates;
- an app-specific device identifier and the app version needed to coordinate records between devices;
- Ink Rush memory events, including internal character and word-context identifiers, rating, stroke-result counts, scheduling values, due date, and review history;
- Ink Rush round records, including start and end times, round type, outcome, reward eligibility, written and recalled counts, accuracy components, and maximum combo;
- Today’s 5 records, including the day, creation time, and internal identifiers of the selected word contexts.
The app-specific device identifier is not your Apple ID and is not intended to identify you by name. Copybook Club does not use private CloudKit progress records for advertising, analytics, or behavioral profiling.
Local notifications
Copybook Club may offer optional practice reminders and free-usage reset reminders. These are local notifications scheduled on your device.
Copybook Club v1.3 registers with Apple Push Notification service so CloudKit can notify the app about private iCloud changes and synchronize them more promptly. The developer does not receive or store the resulting APNs token through Copybook Club systems.
Copybook Club does not operate remote marketing push-notification campaigns in v1.3.
You can manage notification permission through iOS or iPadOS settings and through controls provided in the app where available.
Feedback & support
Optional Bookshelf feedback
After a Bookshelf story, Copybook Club may invite you to answer a voluntary question about whether you liked the story format. If you choose to respond, the app sends your yes-or-no answer to the app’s public Apple CloudKit database so that we can evaluate the format and improve Bookshelf.
The submitted record contains the story identifier, your yes-or-no response, the app version, the app-interface language, and CloudKit’s record-creation date. Copybook Club does not add your name, email address, Apple ID, account ID, device ID, advertising ID, free text, worksheet content, imported files, handwriting, selected story path, collected words, or support messages to this record.
This feedback is separate from the worksheet and progress records stored in your private iCloud database. The developer can access submitted feedback records in the public CloudKit database. Access is controlled through CloudKit security roles. Apple may process technical, account, or record metadata needed to operate CloudKit under Apple’s own terms and privacy policy. For these reasons, we describe the response by the fields we collect rather than promising absolute anonymity.
Individual feedback records are retained for up to 12 months. After that period, we delete the individual records and may retain aggregated totals that are not reasonably linked to a particular response or app installation.
Sending feedback is optional. If you do not answer, the app and Bookshelf remain available in the same way. Feedback is not used for advertising, profiling, or decisions about you.
Bug reports and support emails
If you contact us by email or use the app’s Report a Bug option, we receive the information you choose to include.
The Report a Bug option opens an email addressed to support@copybookclub.app . The message body contains text that you enter.
Copybook Club does not automatically attach your worksheets, imported documents, handwriting, screenshots, recordings, diagnostic files, or recognized text to the email. You may choose to add relevant information yourself.
We use support correspondence to understand and answer your request, investigate problems, maintain reasonable support records, and protect the integrity of the app and support process.
Apple & external services
App Store purchases and reviews
Subscriptions and one-time purchases are processed by Apple through the App Store and StoreKit.
Copybook Club does not receive or store your payment card number or bank details. StoreKit provides the information needed for the app to determine whether Pro access is available and to restore eligible purchases.
Billing, renewals, cancellation, purchase history, and refund requests are managed through your Apple account and Apple’s App Store systems.
If Copybook Club displays Apple’s standard review request, any review you submit is sent to the App Store and is governed by Apple’s systems and policies.
Data sharing and external services
We do not sell personal data and do not use worksheet content or learning progress for advertising.
Copybook Club v1.3 does not include third-party analytics, advertising, or crash-reporting SDKs and does not send app-use or Ink Rush events to an external analytics service. It also does not use third-party OCR, translation, or subscription-management SDKs.
Information may be processed by another service in the following situations:
- Apple provides CloudKit and iCloud storage for synchronized worksheet and progress records;
- Apple provides CloudKit infrastructure for optional Bookshelf feedback in the public database;
- Apple processes App Store purchases, subscriptions, restores, refunds, and reviews;
- your email provider and our email provider process support correspondence;
- an app, printer, cloud-storage provider, or recipient you select processes a file that you export or share.
Those services process information under their own terms, privacy policies, and account settings. Depending on your location and the services involved, information processed through Apple services or sent to support may be processed in Montenegro, the United States, or other countries. You can review Apple’s Privacy Policy . Where applicable law requires safeguards for an international transfer, we use the safeguards required by that law.
Control & rights
Worksheet deletion and data retention
When you delete a worksheet, it is immediately hidden on the device where the deletion was made. If the worksheet contains saved Apple Pencil handwriting, the local drawing file is permanently erased from that device at that time.
Copybook Club creates a small deletion marker so that other devices signed in to the same Apple ID can also stop displaying the worksheet.
A deletion marker may contain the worksheet identifier, deletion date, and an app-specific device identifier. It does not contain the worksheet text, settings, PDF, or handwriting.
The original worksheet record already stored in your private iCloud database is not physically erased when you delete the worksheet in the app. It becomes inactive and stops appearing across synchronized devices, but it continues to remain in your private iCloud storage.
Deletion markers and inactive worksheet records are not removed automatically. Retaining these records allows a device that synchronizes later to reliably learn that the worksheet was deleted and must remain hidden.
Copybook Club does not retrieve these private iCloud records into developer-controlled systems, does not copy them to its own servers, and does not provide an in-app control for permanently erasing them from CloudKit.
To permanently remove Copybook Club’s synchronized worksheet and progress data from iCloud, use Apple’s system iCloud storage management controls. Apple explains that third-party app data can be viewed and deleted through iCloud storage management . The precise menu wording may depend on your device and operating system version.
Deleting Copybook Club from a device does not by itself delete its synchronized data from iCloud. That data remains in your private iCloud storage until you remove it through Apple’s iCloud storage management controls.
Files that you exported, shared, printed, or saved outside Copybook Club are not deleted when you delete a worksheet inside the app. You must manage those copies in the app, folder, cloud service, recipient account, or physical location where you placed them.
Support emails are retained only for as long as reasonably necessary to answer a request, investigate an issue, maintain appropriate support records, protect the support process, or meet legal obligations. The period depends on the nature of the request and any continuing legal or security need.
Individual Bookshelf feedback records are retained for up to 12 months. We may then retain only aggregated response totals that are not reasonably linked to a particular response or app installation. Because Copybook Club does not add an account ID or direct contact identifier to a response, we generally cannot identify and delete one person’s record from an email request alone.
Your choices and privacy rights
You decide which text, files, and photos to import; which extracted or recognized text to keep or edit; which worksheet options to use; whether to save Apple Pencil practice; and where to send exported files.
You can delete worksheets through the controls provided in the app. The effect of worksheet deletion on local and synchronized data is described in Section 14.
Copybook Club does not provide a separate in-app synchronization switch. You can manage iCloud for Copybook Club and remove the app’s synchronized data through Apple’s system iCloud settings. When iCloud is unavailable, the app continues to work locally. Synchronization resumes automatically when iCloud becomes available again.
You can manage notification permission in iOS or iPadOS, restore eligible purchases through the app, and manage subscriptions through your Apple account.
Depending on the law that applies where you live, you may have rights to request access to, correction of, deletion of, restriction of, or portability of personal information; to object to certain processing; to withdraw consent where processing is based on consent; and to lodge a complaint with a competent data protection authority.
These rights are most directly relevant to identifiable information the developer actually receives, such as support correspondence. Bookshelf feedback is not linked by the app to an account or direct contact identifier, so we generally cannot associate an individual feedback record with a support email from you. Copybook Club cannot retrieve worksheet or progress contents that remain only on your device or in your private iCloud database. Use the in-app and Apple system controls described above to manage that information.
To make a privacy request about information we hold, email support@copybookclub.app . We may need enough information to understand the request and reasonably verify that it relates to you. We will respond in accordance with applicable law.
You can choose not to contact support. When contacting us, avoid including information that is not needed to understand your request.
Children’s privacy
Copybook Club is not specifically directed to children. It does not require a Copybook Club account, ask for a child’s name or age, display advertising, or use third-party analytics or advertising SDKs. Copybook Club does not build named child profiles.
If you believe a child has sent personal information to us through a support email or bug report, contact us so we can review the message and delete the information where appropriate.
Changes to this Privacy Policy
We may update this policy when Copybook Club changes or when clarification is needed. When the policy changes, the Last updated date at the top of the page will be revised.
Material changes relating to accounts, analytics, advertising, external processing, cloud storage, remote notifications, or other significant data practices will be reflected in this policy when those practices are introduced.
