Privacy Policy
Last revised:
1. Scope and contact
Eyayoo Studio is the brand used by the individual developer providing these services ("we", "us"). This policy covers our Android and iOS applications and related website and support services that link to or refer to this policy. Store listings show Eyayoo Studio on Google Play and 捷 胡 on the App Store.
Contact us at [email protected] or through our HTTPS contact page. Please include the app name and platform. Features and data processing differ by app, version and platform; the sections below identify when each type applies.
2. On-device data and creative content
Applications save progress, practice results, preferences and, where provided, drawings and recordings in app storage to deliver their features. Full local records are different from the usage events sent to analytics services. The applications covered here do not provide an app-created account or developer-operated cloud synchronization of your progress or works.
In drawing apps with photo or voice features, the camera or microphone is requested when you use the relevant feature. Drawings and recordings are saved on the device. Saving to the photo library or sharing uses the system feature or receiving app you choose; those exported copies have their own storage and privacy controls. The feature does not automatically upload your entire photo library to us.
You can change camera, microphone and photo permissions in system settings. This can prevent the corresponding feature from working. Operating-system backup or device transfer can retain separate copies according to your device and account settings.
3. Usage analytics and choices
Our drawing and training apps use Google Analytics for Firebase to understand feature use and improve the apps. Depending on the app, events include screen and feature visits, level or practice activity, results and duration, and purchase or restore outcomes. The service also processes app-instance identifiers and device, app and network information. These records are not necessarily anonymous.
In updated apps that offer a separate usage-statistics choice, collection is off until you explicitly allow it. You can refuse or withdraw using that app’s privacy settings. Withdrawal stops subsequent collection on that Firebase analytics path and resets its local analytics data; it does not erase previously uploaded records or your local progress and purchased benefits. Older versions and apps without this control do not acquire the new setting merely because this policy has changed; they can have analytics enabled without that in-app switch.
Where linked analytics export is enabled, Google BigQuery holds event-level and user-level analysis copies, including available identifiers and collected usage or purchase events. These copies support analysis and improvement, not restoration of your local progress. They are managed separately from Analytics reports and retention settings.
Reading this policy, accepting the terms, downloading or continuing to use an app, or making a purchase does not authorize optional analytics. Analytics choices, system permissions, advertising choices and purchase-service processing are separate. If your version lacks a choice you need, contact us; this page cannot change the app’s SDK settings.
4. Advertising
In ad-supported app versions, including free training features, Google AdMob processes data such as IP address and approximate location inferred from it, ad and app interactions, diagnostics, and advertising or other identifiers to serve and measure ads and prevent fraud. Rewarded ads apply only where the app offers them. Apps or versions without ads do not use an advertising feature simply because they refer to this policy.
Where applicable, the advertising consent interface and an available advertising-privacy entry let you make or revisit ad choices. On iOS, the system tracking permission is another separate control. Declining tracking does not stop all necessary service processing. An ad-free purchase does not authorize analytics or eliminate transaction processing.
Where AdMob and Analytics are linked, eligible automatic or recommended events, including qualifying purchase events, can support advertising measurement or publisher first-party features subject to the applicable version, service settings and your choices. This does not mean every custom practice event is used for personalized advertising, or override a refusal of advertising consent.
5. Purchases and payment services
Apple App Store or Google Play handles payment through the store you use. The app and Unity IAP process product details, transaction receipts or tokens, purchase status and restoration results to deliver and verify purchased access. We do not ask you to enter payment-card details into our apps.
Unity IAP also has separate transaction-event processing, which can include purchase failures, installation or session identifiers, iOS vendor identifiers, and device, application and regional settings. Depending on the SDK version, technical device attributes can include system startup time and storage capacity. These data support purchasing and related service analysis. A Firebase analytics switch does not control this separate service. Necessary transaction processing does not itself authorize every optional analytical use.
6. Support, website and resource requests
If you email us, we receive your email address, message and any screenshots, recordings, attachments or optional reference you choose to send. We use them to answer your question or address the request, not as a marketing list. Send only what is needed. The website contact form currently prepares a message in your email client; opening a draft does not submit it or upload your device logs.
When you open our website or request online app resources, our hosting, source server and CDN services process requests and related technical information, such as IP address, requested URL, time, response status and client information, to deliver content, monitor performance and protect the service. Cloudflare participates in website delivery and associated access or performance processing. These records are separate from on-device app data. The website stores language and theme preferences locally in your browser.
7. Service providers and their policies
The following services apply to the functions described above, rather than all running in every app. Their policies explain their own processing, safeguards and available controls.
- Google Analytics for Firebase privacy information and Google’s privacy policy: app usage analytics; Google Cloud / BigQuery for linked analysis exports.
- AdMob privacy information: advertising and related diagnostics in ad-supported versions; Google’s privacy policy also covers relevant Google Play platform services on Android.
- Apple privacy policy and Google’s policy: store payments, account and platform records for the store you use.
- Unity privacy policy: Unity IAP purchasing and its related service data; this is distinct from optional Firebase usage statistics.
- Cloudflare privacy policy: website delivery, performance and security processing.
- Alibaba Cloud privacy policy: email infrastructure used for support correspondence; the terms applicable to the mailbox service also govern provider-held copies.
App and advertising services can process technical errors and diagnostic information as part of their operation. Service-related diagnostics are not the same as uploading all of your local app logs to us.
8. Data retention and deletion
How to send a request
To request deletion, use an available in-app contact channel, our website contact page, or email [email protected]. No app account, purchase or enabled analytics is required. The website contact page prepares an email draft; opening it does not send the request. Review and send it through your email service.
Please include the app name, platform (Android or iOS) and data category. Our support team will explain any further information needed to verify your authority or locate records for your specific request. Send only necessary information; do not send passwords, verification codes, payment-card numbers or full receipts.
We assess your authority, the relevant services and records that can be located under our control, then explain the available action and any retention requirement or limitation. For records processed on our behalf, handling may require us to instruct the provider. A single email does not automatically locate or erase every record held by a third party.
Local data on your device
Local progress, preferences, drawings and recordings remain in app storage until removed through an available app function or device data control. An email request cannot remotely erase files held only on your device. Where an app offers deletion of a work or recording, use that function for the selected item. Save or export anything you want to keep before deleting data.
- Android: system app settings distinguish clearing cache from clearing storage or app data. Clearing storage/data removes local app information; clearing cache alone is not a full-data deletion. Labels vary by device. An app’s downloaded-resource cache cleanup is also distinct from clearing local app records.
- iOS: Offload App keeps documents and data; Delete App removes the app and its related device data. Neither operation requests deletion of provider-held records. Review the device’s storage controls before proceeding.
- Separate copies: photos saved to the library, shared files, system/cloud backups and data on other devices need separate management through their respective services. Reinstalling or restoring a backup can bring data back.
Stopping analytics and requesting historical-data deletion
Where an app provides a usage-statistics setting, turning it off stops subsequent collection on that analytics path. This does not erase uploaded history, advertising data, purchase records or your local progress. Do not enable statistics just to make a privacy request.
Analytics records, linked BigQuery exports, advertising data, Firebase installation records, local progress, purchase rights and support email are distinct. Deletion in one service does not prove deletion in another, and an email address alone may not identify SDK records. Information needed to locate records may be lost after a reset or reinstall, may not be recoverable, and may not cover every historical record.
Retention, providers and necessary limits
Usage analytics follows the relevant service settings. Aggregated reports and BigQuery event-level or user-level exports are managed separately: resetting the app or expiry of Analytics retention does not automatically delete warehouse copies. Advertising, Firebase installation and Unity service records also require their own handling under the applicable purposes, settings and provider rules. There is no single retention period for all these data.
For support messages and attachments, we consider whether the issue is resolved, whether the request still needs handling and any legal recordkeeping obligation. Original messages and attachments are assessed separately from the minimum record needed to document a request and its outcome. Mailbox recovery, archives, synchronization and backups have separate controls and need separate checks.
Website and resource access logs follow the relevant host or CDN’s rotation and retention settings; they may not be identifiable by email address. Store accounts, transactions and fraud-prevention records are managed through Apple or Google and can be retained under store rules and applicable legal obligations. Deleting local app data or support correspondence does not itself cancel a purchase.
Where a provider processes data independently, its privacy-request channel also applies. For Unity’s independent processing, this can include [email protected]. See service providers and their policies for the relevant channels, and the Terms of Service for purchase information.
We explain records that cannot be located or removed and any applicable retention requirement. We cannot promise immediate removal of all copies or one fixed completion deadline across services. Receiving a request or a provider acknowledgment is not proof that deletion is complete. Stopping future collection, deleting local data and handling previously uploaded records remain separate actions.
9. Your requests and rights
Depending on applicable law, you may have rights to access, correct or delete data, restrict or object to processing, request portability, withdraw consent, or complain to the appropriate supervisory authority.
To exercise a right or ask about your data, follow Data retention and deletion above. It explains how to contact us, the minimum information needed, applicable verification and the separate handling of local data and provider-held records.
10. Security, international processing and children
We use HTTPS for website and network service connections where provided, and limit the information requested to the purpose of the interaction. No network or storage method offers absolute security. Service providers may process data outside your country; linked BigQuery analysis data can be held in the United States. Applicable provider terms and legal safeguards govern these transfers.
Our apps have different audiences, including drawing experiences intended for children. Parents and guardians should review the particular app’s store information, supervise purchases and sharing, and manage device permissions. A single age threshold does not describe every app or jurisdiction. If you believe a child’s information was processed inappropriately, contact us with the app and relevant circumstances so we can assess the applicable requirements and available action.
11. Policy updates
Revisions are shown with the date on this page. For material changes, notice or a new choice is provided where applicable law requires it. A policy update does not automatically turn on optional data collection. The Terms of Service describe service use and purchasing; they do not replace privacy choices.
隐私政策
最近修订:
1. 适用范围与联系
Eyayoo Studio 是提供相关服务的个人开发者使用的品牌（下称“我们”）。本政策适用于由我们提供并链接或引用本政策的 Android、iOS 应用及相关网站和客服服务。Google Play 的开发者展示名称为 Eyayoo Studio，App Store 为“捷 胡”。
您可以发送邮件至 [email protected]，或访问 HTTPS 联系页面。请注明应用名称与平台。功能和数据处理因应用、版本及平台而异；下文分别说明适用情形。
2. 设备数据与创作内容
应用在设备的应用存储中保存进度、练习结果、偏好，以及在提供相应功能时保存绘画和录音，用于实现相关功能。完整本地记录与发送给分析服务的使用事件不同。这里涵盖的应用不提供应用自建账号，也不提供由开发者运营的进度或作品云同步。
在带有拍照或语音功能的绘画应用中，使用对应功能时会请求相机或麦克风权限。绘画与录音保存在设备上。保存到相册或分享时，由您选择的系统功能或接收应用处理；导出的副本有其独立的存储和隐私控制。这些功能不会自动将整个相册上传给我们。
您可在系统设置中调整相机、麦克风和照片权限；这可能使对应功能无法使用。操作系统备份或设备迁移可能按您的设备及账号设置另行保留副本。
3. 使用统计与选择
我们的绘画和训练应用使用 Google Analytics for Firebase 了解功能使用情况并改进应用。事件因应用而异，包括页面与功能访问、关卡或练习活动、结果与用时，以及购买或恢复结果。该服务也处理应用实例标识和设备、应用、网络信息。这些记录不一定是匿名数据。
在提供独立“使用统计”选择的更新应用中，统计在您明确允许前保持关闭。您可通过该应用的隐私设置拒绝或撤回。撤回会停止这条 Firebase 统计链的后续收集，并重置本机分析数据；不会删除已经上传的记录，也不会删除本地进度和已购权益。旧版本及没有该控制的应用不会因本政策更新而自动获得新设置；这些版本可能没有应用内开关但已启用统计。
在启用关联分析导出的服务中，Google BigQuery 保存事件级与用户级分析副本，包括可用标识及已收集的使用或购买事件。这些副本用于分析和改进，不用于恢复本地进度；它们与 Analytics 报告及保留设置分别管理。
阅读本政策、接受条款、下载或继续使用应用、购买付费功能，都不构成对可选统计的授权。统计选择、系统权限、广告选择和购买服务处理是分别独立的。如果您的版本缺少所需选择，请联系我们；网页本身不能改变应用的 SDK 设置。
4. 广告
在含广告的应用版本中（包括免费训练功能），Google AdMob 处理 IP 地址及由此推导的大致位置、广告与应用交互、诊断，以及广告或其他标识，用于提供和衡量广告、防范欺诈。奖励广告仅适用于实际提供该功能的场景。不含广告的应用或版本不会因引用本政策而新增广告功能。
适用时，广告同意界面及可用的广告隐私入口让您作出或重新调整广告选择。iOS 的系统跟踪权限是另一项独立控制；拒绝跟踪不表示所有必要服务处理停止。购买免广告权益不构成统计授权，也不会停止交易处理。
在 AdMob 与 Analytics 已关联时，符合条件的自动或推荐事件（包括符合条件的购买事件）可在适用版本、服务设置及用户选择允许的范围内支持广告衡量或发布商第一方功能。这不表示所有自定义练习事件都用于个性化广告，也不能覆盖拒绝广告同意的选择。
5. 购买与支付服务
Apple App Store 或 Google Play 按您使用的商店处理付款。应用及 Unity IAP 处理商品信息、交易票据或令牌、购买状态与恢复结果，以提供并核验已购权限。我们不要求您在应用内向我们输入银行卡信息。
Unity IAP 还有独立的交易事件处理，涉及购买失败、安装或会话标识、iOS 供应商标识，以及设备、应用和地区设置。因 SDK 版本不同，技术设备属性可包括系统启动时间和存储容量。这些数据用于购买及相关服务分析。Firebase 统计开关不控制这一独立服务；必要交易处理本身不构成对所有可选分析用途的授权。
6. 客服、网站与资源请求
您向我们发送邮件时，我们收到您的邮箱地址、正文，以及您主动发送的截图、录音、附件或可选参考信息。这些信息用于回复问题或处理请求，不用作推广名单。请仅提供必要资料。网站联系表单目前在您的邮件客户端准备邮件；打开草稿不等于提交，也不会上传设备日志。
您打开网站或请求应用在线资源时，托管、源站和 CDN 服务处理请求及相关技术信息，例如 IP 地址、请求网址、时间、响应状态和客户端信息，用于提供内容、监测性能与保护服务。Cloudflare 参与网站分发及相关访问或性能处理。这些记录与设备内应用资料不同。网站在浏览器本地保存语言和主题偏好。
7. 服务提供方及隐私政策
下列服务对应上述具体功能，并非在每款应用中全部运行。其隐私政策说明各自的数据处理、保护措施与可用控制。
- Google Analytics for Firebase 隐私说明及 Google 隐私政策：应用使用分析；Google Cloud / BigQuery 用于已关联的分析导出。
- AdMob 隐私说明：含广告版本的广告及相关诊断；Android 上相关 Google Play 平台服务也适用 Google 隐私政策。
- Apple 隐私政策及 Google 隐私政策：您使用的商店所处理的支付、账号和平台记录。
- Unity 隐私政策：Unity IAP 购买及其相关服务数据，与可选的 Firebase 使用统计分开。
- Cloudflare 隐私政策：网站分发、性能与安全处理。
- 阿里云隐私政策：客服邮件使用的邮箱基础设施；服务方保存的副本也受邮箱服务适用条款管理。
应用及广告服务会在运行中处理技术错误与诊断信息。服务相关诊断也不等于将您全部本地应用日志上传给我们。
8. 数据保留与删除
如何提出请求
您可通过应用内可用的联系渠道、官网联系页，或发送邮件至 [email protected] 申请删除资料。申请无需应用账号、购买或开启统计。官网联系页会准备邮件草稿；打开草稿不等于提交申请，请通过您的邮件服务检查并发送。
请注明应用名称、平台（Android 或 iOS）及数据类别。客服会按具体请求说明核验您的权限或定位记录所需的进一步信息。请仅提供必要资料，不要发送密码、验证码、银行卡号或完整票据。
我们会评估您的申请权限、相关服务及能定位的可控记录，再说明可执行的处理、保留要求或限制。服务方代我们处理的记录，可能需要由我们向其提出指示。一封邮件不会自动定位或清除所有第三方持有的记录。
设备上的本地资料
本地进度、偏好、绘画和录音保存在应用存储中，直到您通过应用提供的功能或设备的数据管理操作移除。邮件请求无法远程删除仅保存在您设备上的文件。应用若提供删除作品或录音功能，可针对选定项目使用该功能。删除前，请保存或导出需要保留的资料。
- Android：系统应用设置区分清除缓存与清除存储空间/应用数据。清除存储或数据会移除本地应用资料；仅清缓存不等于删除全部数据。具体名称因设备而异。应用内的下载资源缓存清理也不同于清除本地应用记录。
- iOS：“卸载 App”（Offload App）会保留文稿与数据；“删除 App”（Delete App）会移除应用及其相关设备数据。这两种操作都不是向服务方提交删除请求。操作前请查看设备存储管理中的说明。
- 独立副本：保存到相册的照片、已分享文件、系统或云备份及其他设备上的资料，需要通过对应服务分别管理。重装或恢复备份可能重新带回数据。
停止统计与申请删除历史资料
应用提供使用统计设置时，关闭统计会停止相应分析链的后续收集。这不会删除已上传历史、广告资料、购买记录或本地进度。请勿仅为提出隐私请求而开启统计。
Analytics 记录、关联 BigQuery 导出、广告资料、Firebase 安装记录、本地进度、购买权益和客服邮件分别处理。在一个服务中删除不证明另一个服务也已删除；仅凭邮箱地址也不一定能定位 SDK 记录。重置或重装可能使定位记录所需的信息丢失且无法恢复，现有信息也可能无法覆盖全部历史记录。
保留规则、服务方与必要限制
使用统计按相关服务设置保存。汇总报告和 BigQuery 事件级或用户级导出分别管理：重置应用或 Analytics 中的保留期届满，不会自动删除分析仓库副本。广告资料、Firebase 安装记录和 Unity 服务记录也需按各自适用的用途、设置及服务方规则处理。这些资料没有一个共用的统一保存期限。
判断客服邮件与附件的保留需要时，我们考虑问题是否已解决、是否仍需处理请求，以及是否存在法定记录义务。原邮件和附件与证明申请及处理结果所需的最小记录分别评估。邮箱恢复、归档、同步和备份有各自的控制方式，需要分别检查。
网站及资源访问日志按相应托管或 CDN 的轮换和保留设置管理，可能无法通过邮箱地址定位。商店账号、交易和防欺诈记录通过 Apple 或 Google 管理，也可能依商店规则及适用法律义务保留。删除应用本地资料或客服邮件本身不会取消购买。
服务方独立处理的资料也适用其自身隐私请求渠道。Unity 独立处理的资料可涉及 [email protected]。相关渠道见服务提供方及隐私政策，购买说明见服务条款。
无法定位或移除的记录，以及适用的保留要求，我们会说明情况。我们无法承诺立即移除全部副本，或为所有服务设定同一个删除完成期限。收到申请或服务方受理回执不代表删除已经完成。停止后续收集、删除本地资料和处理已上传记录仍是分别独立的操作。
9. 您的请求与权利
依适用法律，您可能享有访问、更正或删除资料、限制或反对处理、请求可携带、撤回同意，以及向适当监管机关投诉等权利。
如需行使权利或询问您的资料，请参阅上文数据保留与删除，了解联系方式、所需最少信息、适用的核验，以及本地资料和服务方记录的分别处理方式。
10. 安全、跨境处理与儿童使用
网站及提供的网络服务连接使用 HTTPS，并围绕交互目的限制所请求的信息。任何网络或存储方式都无法保证绝对安全。服务方可能在您所在国家或地区以外处理数据；关联的 BigQuery 分析数据可保存在美国。这些传输受适用服务方条款及法律保障要求约束。
我们的应用面向不同人群，包括供儿童使用的绘画体验。家长或监护人应查看具体应用的商店说明，监督购买和分享，并管理设备权限。一个固定年龄门槛不能代表所有应用和地区。如果您认为儿童信息被不当处理，请告知应用及相关情况，以便我们评估适用要求及可采取的措施。
11. 政策更新
本页面通过修订日期标明更新。对于重大变更，按适用法律要求作出通知或提供新的选择。政策更新不会自动开启可选数据收集。服务条款说明服务使用与购买规则，不替代隐私选择。
