# 数据与会员

## 数据保存在哪里？

Daak 不要求注册独立账号。你创建的账单、账户、预算、计划等个人记账资料保存在设备本地；iCloud 可用时，会通过你自己的 iCloud 自动同步。

| 状态                  | 数据保存与同步方式                                               |
| ------------------- | ------------------------------------------------------- |
| **未开启或无法使用 iCloud** | 资料只保存在当前设备                                              |
| **开启 iCloud**       | 私人资料保存到当前 Apple ID 的 iCloud 私有数据库，并同步到使用同一 Apple ID 的设备 |
| **使用共享功能**          | 只有主动共享的账本、账户或存钱计划及其关联资料，会通过 iCloud 提供给受邀成员              |

{% hint style="warning" %}
资料只保存在当前设备时，更换设备或删除 App 前应先创建备份。
{% endhint %}

Daak 没有独立的记账资料服务器，不会把你的账单、账户或计划保存到 Daak 自建账号中。市场价格等在线内容会从 Daak 的数据服务获取，但不会包含你的个人记账资料。

需要了解同步、共享和备份操作时，请查看 [iCloud 与共享](/zh-cn/shu-ju-yu-gong-xiang/sync-and-sharing.md)和[导入、导出与迁移](/zh-cn/shu-ju-yu-gong-xiang/backup-and-import.md)。

## 会员与哪个账户关联？

会员购买和恢复由 Apple App Store 管理，会员资格绑定购买时使用的 **App Store Apple ID**，不是绑定某台设备，也不绑定 Daak 记账资料。

更换设备或重新安装后，请登录购买会员时使用的 App Store Apple ID，再在会员页面点击 **恢复购买**。

| 账户                     | 用途             |
| ---------------------- | -------------- |
| **iCloud Apple ID**    | 保存、同步和共享个人记账资料 |
| **App Store Apple ID** | 购买、续订和恢复会员资格   |

{% hint style="info" %}
两个 Apple ID 可以不是同一个账号。数据没有出现时检查 iCloud 账号；会员没有恢复时检查 App Store 账号。
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.daak2.com/zh-cn/bang-zhu/data-and-membership.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
