隐私政策

我们是谁

Chuyện Nhỏ 由 ERPCons & LPC 运营，是通过本网站处理的个人数据的控制方。个人数据相关联系：contact@lpc.vn。

我们的原则

• On-device processing: the free tools do not upload your files to a server.
• 最少化：只处理运营和防止滥用所必需的数据。
• Accounts are optional: the tools need no name, email or phone number. We only learn your email when you choose to sign in.
• No third-party analytics, advertising or tracking tools. The only cookie is the sign-in session cookie, set only when you sign in.

我们处理的数据及目的

• 工具打开次数：工具名称和时间，用于统计总使用次数。只保存汇总计数，不与用户关联。
• IP 地址：使用密钥进行单向哈希处理，仅用于限制自动提交，约 1 小时后自动删除。
• 反馈、建议内容：仅在你勾选同意并点击“提交”后接收，用于审核和改进工具。回执编号仅以哈希形式保存。
• Web 服务器的技术日志（IP 地址、浏览器类型、访问的页面）：仅用于系统运营和安全，在必要的短时间内保存。

If you have an account

• Email: to sign in, to send confirmation codes when you create an account or forget the password, and for account emails (Pro ending soon, saved items about to be deleted). Never used for advertising.
• Password: only a one-way hash is stored (scrypt, with a salt per account); nobody, administrators included, can read the original password back.
• Sign-in session: the cn_session cookie (HttpOnly, used only to keep you signed in); the server keeps a hash of the session with when it was created and last used.
• Display name and whether to credit you on published suggestions, only if you fill them in.
• Suggestions sent while signed in are linked to your account so you can follow their status and add sources.
• Pro plan: start date, end date and the history of grants and withdrawals.

AI assistant and storage (Pro)

This applies only when you use the Pro plan and turn these features on yourself:

• The AI key you enter is passed straight to the assistant server (GoClaw) that we operate and stored there encrypted. The Chuyện Nhỏ database keeps only the provider type, model and status, never the key.
• Conversations, tool results you attach for a source check and images you attach are sent to the AI provider you chose (for example OpenAI, Google, Anthropic, OpenRouter) and may be processed abroad under their policies. Chat history is kept on the assistant server so you can reopen it.
• So the assistant can remember context, the assistant server may summarise finished conversations with an AI model we configure, not with your key.
• Attached images are stored briefly on the Chuyện Nhỏ server so the assistant server can download them once; the temporary copy is deleted right after sending, at the latest after 7 days.
• Source-check history: the tool, the time and the state of the suggestion draft. Questions are not stored.
• Saved items: figures you choose to save in some tools, and your favourite tools.

保存在你设备上的数据

部分工具会把数据直接保存在你的浏览器中以便再次使用：最近使用的工具、浅色/深色模式、家庭日历、笔记、简历草稿、记忆卡片。这些数据不会发送给我们；你可以在工具内直接删除，或在浏览器设置中清除网站数据。

与第三方共享

我们不出售个人数据，也不为广告目的共享个人数据。仅在法律要求时，我们才会向有管辖权的国家机关提供数据。

When you use the AI assistant, content is sent to the AI provider you chose, with your key. How that provider handles the data is governed by the terms between you and them.

唯有“录音转文字”工具使用浏览器自带的语音识别服务。音频由浏览器发送给该浏览器的提供商（例如 Chrome 对应 Google），可能依其政策在境外处理，且不经过我们的服务器。

保存期限

• IP 地址的哈希值：约 1 小时。
• 使用次数：以汇总统计形式保存，不含个人数据。
• 反馈、建议：在审核和跟进所需的时间内保存，或保存至你要求删除为止。
• Account: until you delete it. A sign-in session expires after 30 days without use (staff accounts: 12 hours).
• Saved items: while you have Pro; after Pro ends they stay read-only for 90 days and are then deleted, with an email at least 7 days before.
• Images attached for the AI assistant: deleted right after sending, at the latest after 7 days.
• Emails we send you: the content (including confirmation codes) is removed from the queue as soon as it is sent; only the recipient, the type of email and the delivery status are kept.

你的权利

根据《个人数据保护法》，你有权：

• 知悉自己个人数据的处理情况。
• 给予同意或撤回同意。
• 查看、更正、要求删除或限制处理数据。
• 依法投诉、举报、提起诉讼。
• 要求有管辖权的机关保护你的个人数据权利。

如何行使权利

Send your request to contact@lpc.vn. If you have an account, you can view it, change your display name and delete it yourself on the Account page. For feedback sent without signing in, include the receipt code so we can find the right content.

我们会在 2 个工作日内确认收到请求，并在法律规定的期限内处理，最迟不超过 20 天。

Deleting your account

You can delete your account on the Account page by typing your email again. We delete your email, sessions, Pro plan, saved items, source-check history, suggestion drafts, and your AI assistant and AI key on the assistant server.

Suggestions you already sent are kept because they may have been published, but they are no longer linked to you. We keep only a record that a deletion happened, by account id and without the email.

儿童

Chuyện Nhỏ does not collect information to identify children. Children who want to send feedback or create an account need the consent of a parent or guardian, as required by law.

安全

本网站通过 HTTPS 加密连接运行。接收的数据会尽量最少化，并在可能时进行哈希处理。没有任何系统是绝对安全的；如发生影响个人数据的事件，我们将依法进行通报。

政策变更

政策变更时，我们会更新页面顶部的日期，并就重要变更在网站上发布公告。
