一、我们收集和处理的信息

1. 您主动创建的信息

为提供习惯记录和个人资料功能，本应用会在您的设备本地处理以下信息：

• 习惯与打卡数据：习惯名称、分类、提醒时间、目标频率、创建时间及打卡日期。
• 个人资料：您设置的昵称和个人描述。
• 头像图片：您主动通过相机拍摄或从相册选择的图片。

2. 设备权限产生的信息

当您主动使用更换头像功能时，本应用会根据您的选择请求相机或相册访问权限。所选头像会复制并保存在本应用的本地文件目录中。本应用不会将头像上传至服务器，也不会对图片内容进行识别、分析或用于其他目的。

3. 当前版本不会收集的信息

本应用当前不提供账号注册服务，不会主动收集您的真实姓名、手机号码、电子邮件地址、通讯录、精确位置、Android ID、广告标识符、IP 地址、应用使用分析数据或崩溃日志。

二、我们如何使用信息

本应用仅为实现以下本地功能而处理相关信息：

• 展示、创建和删除您的习惯，以及记录或取消打卡；
• 计算完成率、连续打卡天数和所选日期范围内的统计结果；
• 展示并保存您设置的昵称、个人描述和头像；
• 维护应用正常运行并响应您主动执行的操作。

我们不会将上述信息用于广告投放、用户画像、自动化决策或与本应用功能无关的营销活动。

三、信息的共享、转让与披露

本应用当前没有用户数据服务器，不会出售、交换、出租、上传或主动向第三方共享您的个人信息。

仅在以下法定情形下，信息可能被依法处理：

• 已获得您的明确同意；
• 根据适用法律法规、司法程序或有权机关的合法要求必须提供；
• 为保护您、其他用户或公众的人身和财产安全，在法律允许的范围内确有必要。

由于本应用的数据保存在您的设备中，如发生上述情形，通常需要由您本人或设备控制者依法提供相关数据。

四、信息的存储与安全

• 存储位置：习惯、打卡和个人资料均保存在您的设备本地，不会由我们进行跨境传输。
• 保存期限：数据会持续保留，直至您修改或删除相关内容、清除应用数据或卸载本应用。
• 设备备份：您的操作系统或设备厂商可能根据您启用的备份设置备份应用数据，该过程由相应平台提供商管理，并受其隐私政策约束。
• 安全提示：请妥善保管并锁定您的设备。设备遗失、被破解或由他人使用时，本地数据可能存在被访问的风险。

我们采取与本应用规模和数据处理方式相适应的措施保护信息安全，但任何电子存储方式都无法保证绝对安全。

五、您的权利

您可以通过本应用或设备系统设置行使以下权利：

• 在“我的”页面查看和修改昵称、个人描述及头像；
• 在习惯页面查看或删除习惯，并记录或取消打卡；
• 通过“恢复默认头像”删除本应用保存的自定义头像；
• 在设备系统设置中撤回相机或相册权限，撤回后仅影响对应的头像选择方式；
• 通过清除应用数据或卸载本应用删除全部本地数据。

本应用当前不提供账号体系，因此不存在账号注销事项。如您无法通过上述方式处理数据，可以通过本政策末尾的联系方式与我们联系。

六、设备权限与第三方服务

本应用使用 Flutter 提供的本地功能组件，包括图片选择、本地键值存储和应用目录访问组件。这些组件仅用于调用操作系统的相机或相册选择器、保存偏好设置和定位本地文件目录，不会因此将您的数据发送给组件提供方。

当前版本未集成广告、行为分析、社交登录、云存储或消息推送等第三方网络服务。未来如新增会处理个人信息的第三方服务，我们将更新本政策并依法履行告知或征得同意义务。

七、未成年人隐私

本应用主要面向具备完全民事行为能力的用户。未满 14 周岁的未成年人应在父母或其他监护人同意和指导下使用本应用。我们不会故意收集未成年人的个人信息。若监护人认为未成年人的信息被不当处理，请通过本政策末尾的联系方式联系我们，我们将在核实后及时处理。

八、隐私政策的变更

我们可能根据应用功能变化、法律法规要求或服务调整更新本隐私政策。发生重大变更时，我们将通过应用内提示、版本说明或其他合理方式告知您。更新后的政策将在标明的生效日期起生效。

九、联系我们

如您对本隐私政策有任何疑问、意见、投诉，或希望行使个人信息相关权利，可以通过以下方式联系我们。我们将在收到请求并核实必要信息后，在法律规定的期限内予以处理。

1. Information We Collect and Process

1.1 Information you create

To provide habit tracking and profile features, the App processes the following information locally on your device:

• Habit and check-in data: habit name, category, reminder time, target frequency, creation date, and check-in dates.
• Profile information: the display name and profile description you provide.
• Avatar image: an image you take with the camera or select from your photo library.

1.2 Information associated with device permissions

When you choose to change your avatar, the App requests camera or photo library access based on your selection. The selected image is copied to and stored in the App's local directory. The App does not upload the image to a server, analyze or identify its contents, or use it for any other purpose.

1.3 Information the current version does not collect

The App currently does not offer account registration and does not actively collect your legal name, phone number, email address, contacts, precise location, Android ID, advertising identifier, IP address, usage analytics, or crash logs.

2. How We Use Information

The App processes information only to provide the following local features:

• Displaying, creating, and deleting habits, and recording or canceling check-ins;
• Calculating completion rates, check-in streaks, and statistics for a selected date range;
• Displaying and saving your display name, profile description, and avatar; and
• Maintaining normal operation of the App and responding to actions you initiate.

We do not use this information for advertising, profiling, automated decision-making, or marketing unrelated to the App's features.

3. Sharing, Transfer, and Disclosure

The App currently has no user-data server. We do not sell, exchange, rent, upload, or actively share your personal information with third parties.

Information may be processed as required by law only in the following circumstances:

• We have obtained your explicit consent;
• Disclosure is required by applicable laws, legal proceedings, or a lawful request from a competent authority; or
• It is necessary, within the scope permitted by law, to protect the personal or property safety of you, other users, or the public.

Because App data is stored on your device, in these circumstances the relevant data would generally need to be provided by you or the person who controls the device.

4. Storage and Security

• Storage location: habits, check-ins, and profile information are stored locally on your device and are not transferred across borders by us.
• Retention: data remains stored until you modify or delete it, clear the App's data, or uninstall the App.
• Device backups: your operating system or device manufacturer may back up App data according to settings you enable. Such backups are managed by the relevant platform provider and governed by its privacy policy.
• Security notice: please protect and lock your device. Local data may be accessed if your device is lost, compromised, or used by another person.

We use measures appropriate to the scale of the App and its data-processing methods to protect information. However, no electronic storage method can guarantee absolute security.

5. Your Rights

You can exercise the following rights through the App or your device settings:

• View and edit your display name, profile description, and avatar on the Profile page;
• View or delete habits and record or cancel check-ins on the Habits page;
• Delete the custom avatar stored by the App by selecting “Restore Default Avatar”;
• Withdraw camera or photo library permission in your device settings; doing so affects only the corresponding avatar selection method; and
• Delete all local data by clearing the App's data or uninstalling the App.

The App currently has no account system, so account deletion is not applicable. If you cannot manage your data through the methods above, contact us using the details at the end of this policy.

6. Device Permissions and Third-Party Services

The App uses local Flutter components for image selection, local key-value storage, and access to the App directory. These components are used only to invoke the operating system's camera or photo picker, save preferences, and locate local file directories. They do not cause your data to be sent to the component providers.

The current version does not integrate third-party network services for advertising, behavioral analytics, social sign-in, cloud storage, or push notifications. If a future version adds a third-party service that processes personal information, we will update this policy and provide notice or obtain consent as required by law.

7. Children's Privacy

The App is primarily intended for users with full legal capacity. Children under the age of 14 should use the App only with the consent and guidance of a parent or other legal guardian. We do not knowingly collect children's personal information. If a guardian believes that a child's information has been handled improperly, please contact us using the details at the end of this policy. We will investigate and take appropriate action promptly.

8. Changes to This Privacy Policy

We may update this Privacy Policy to reflect changes to App features, legal requirements, or services. If a material change is made, we will notify you through an in-app notice, release notes, or another reasonable method. The updated policy takes effect on the effective date shown above.

9. Contact Us

If you have questions, comments, or complaints about this Privacy Policy, or wish to exercise your privacy rights, contact us using the details below. After receiving your request and verifying any information reasonably necessary, we will respond within the period required by applicable law.
