你的数据,我们怎么处理
生效日期:2026 年 11 月 9 日 · 版本 1(内测版)
Matcha 是一个住在你桌面上的 AI 伙伴。为了陪你聊天、记住你在意的事,它需要保存一些你的数据。这份政策用尽量直白的话说明:我们收集什么、为什么收集、交给谁处理、保存多久,以及你怎样导出和删除。本政策适用于 Matcha 桌面应用、网站 matcha-mini.com 以及登录服务。
1. 我们收集的信息
账号
- 用户名和密码。密码只以加密哈希的形式保存在登录服务(Logto,由我们自己运行)中,我们看不到明文。
- 你在应用里设置的昵称、时区和界面语言。
你在 Matcha 里产生的内容
- 对话和其中的消息。
- 你确认过的记忆、Matcha 提出的记忆建议,以及每条记忆来自哪段对话。
- 根据对话自动生成的摘要(每段对话、每个话题、每一天)。
- 任务、专注记录、重要的日子、Matcha 的休息状态,以及今日计划草稿。
- 用于查找相关记忆的“向量”。它由我们自己服务器上的模型计算,不会发送给任何第三方。
使用和运行记录
- 每天的消息数、计划草稿数和模型用量(token 数),用于每日使用上限。
- 操作记录:导出数据、删除对话或记忆、注销账号时,会记下发生了什么操作和时间,不含任何内容。
- 登录记录:登录服务会为每次登录和注册记录 IP 地址、设备和浏览器信息以及时间,用于安全防护。
- 服务器日志:每个请求的方法、路径、状态码、耗时和请求编号。日志里没有你的消息内容,也没有你的 IP 地址。
只保存在你电脑上的
- 登录凭证保存在 Windows 凭据管理器中。
- 应用的错误日志(client.log)保存在你的电脑上,不会自动上传。
我们不收集的
- 屏幕内容、键盘输入、通讯录和位置。
- 麦克风和摄像头。语音功能上线前,我们会先更新本政策。
- 网站不使用 Cookie,也不做任何访问统计,只在你的浏览器里记住语言选择。
2. 我们如何使用这些信息
- 生成 Matcha 的回复,提出记忆建议,整理对话摘要,拟今日计划草稿。
- 在之后的对话里找出相关的记忆,让 Matcha 记得你告诉过它的事。
- 执行每日使用上限,保障服务安全,排查故障。
我们不出售你的数据,不用于广告,也不用它训练模型。我们不会主动查看你的对话和记忆;只有在你请我们排查问题并同意时,或者法律要求时,才会接触相关数据。
3. 交给谁处理
- DigitalOcean(服务器托管,美国旧金山):上面说的所有服务器端数据都存储在这里。
- DeepSeek(深度求索,中国):生成回复、记忆建议、摘要和计划草稿时,相关的对话内容、记忆和你当天的安排会发送到 DeepSeek 的 API 进行处理。DeepSeek 按其 API 服务条款处理这些数据。
- Cloudflare:只为我们的域名提供解析(DNS),你的数据不经过 Cloudflare。
- Let's Encrypt:只用于签发 HTTPS 证书,不接触你的数据。
除此之外,我们不会把你的数据提供给其他人。
4. 存储地点和跨境传输
我们的服务器位于美国。生成回复等处理会把相关内容发送到位于中国的 DeepSeek。使用 Matcha 即表示你的数据会被传输到美国和中国处理。
5. 保存多久
- 你的账号和内容会一直保存,直到你删除它们或注销账号。
- 删除一条记忆或一段对话会立即生效。删除对话时,只来自这段对话的记忆和摘要也会一起删除。
- 注销账号会立即删除你在 Matcha 的全部数据,登录账号随后由后台任务删除,通常在几秒内完成,失败时会在一小时内反复重试。
- 我们每天备份一次数据库,备份保留 30 天。已删除的数据在到期前仍可能留在备份中;如果从备份恢复,我们会重新执行恢复后发生过的所有注销。
- 登录记录最多保留 30 天;注销账号后,你的登录记录会在一天内删除。
- 服务器日志按大小滚动删除,每个服务最多保留约 50 MB,通常是几天到几周。
- 注销后我们只保留两样东西:一个由登录编号计算出的哈希值,用来防止旧的登录凭证重新创建账号,它无法还原成你的用户名;以及一条不含任何内容的“账号已注销”记录。
6. 你的权利
- 查看和修改:在应用里随时查看、修改和删除你的记忆、对话、任务和日程。
- 导出:设置 → 你的数据 → 导出,会得到一个包含你全部数据的文件。用于查找记忆的向量可以由内容重新计算,所以不包含在内。
- 注销:设置 → 账号 → 注销账号,会删除你的全部数据和登录账号。
- 其他请求,比如更正信息或询问数据处理情况,请通过下方方式联系我们。
7. 安全
所有连接都使用 HTTPS 加密;每个人的数据在数据库层面相互隔离,一个账号无法读取另一个账号的数据;服务器只能用密钥登录。Matcha 目前处于内测阶段,服务可能中断,也可能因故障丢失数据,重要内容请定期导出备份。
8. 未成年人
Matcha 不面向 14 岁以下的儿童。如果你发现孩子在未经监护人同意的情况下使用了 Matcha,请联系我们,我们会删除相关账号和数据。
9. 政策变更
本政策可能随功能变化而更新,更新后会修改上方的生效日期。重要变更(例如新增数据收集或新的第三方)会在应用或网站上提前告知。
Privacy policy
How we handle your data
Effective 9 November 2026 · Version 1 (beta)
Matcha is an AI companion that lives on your desktop. To chat with you and remember what matters to you, it has to keep some of your data. This policy explains, as plainly as we can, what we collect, why, who processes it, how long we keep it, and how you can export and delete it. It covers the Matcha desktop app, the website matcha-mini.com and the sign-in service.
1. What we collect
Account
- Username and password. The password is stored only as a hash in the sign-in service (Logto, which we run ourselves); we never see it in plain text.
- The nickname, time zone and interface language you set in the app.
What you create in Matcha
- Conversations and their messages.
- Memories you confirmed, memory suggestions Matcha made, and which conversation each memory came from.
- Summaries generated from your conversations (per conversation, per topic, per day).
- Tasks, focus sessions, important dates, Matcha's rest state and daily plan drafts.
- "Vectors" used to find relevant memories. They are computed by a model on our own server and never sent to a third party.
Usage and operation records
- Daily counts of messages, plan drafts and model usage (tokens), for the daily limits.
- Activity records: when you export data, delete a conversation or memory, or delete your account, we record what happened and when, without any content.
- Sign-in records: the sign-in service records the IP address, device and browser, and time of each sign-in and sign-up, for security.
- Server logs: method, path, status, duration and request id of each request. They contain neither your messages nor your IP address.
Kept only on your computer
- Your sign-in credential, in Windows Credential Manager.
- The app's error log (client.log); it is never uploaded automatically.
What we don't collect
- Screen content, keystrokes, contacts or location.
- Microphone or camera. We will update this policy before voice features launch.
- The website uses no cookies and no analytics; it only remembers your language choice in your browser.
2. How we use it
- To generate Matcha's replies, suggest memories, summarise conversations and draft daily plans.
- To find relevant memories in later conversations, so Matcha remembers what you told it.
- To enforce daily limits, keep the service secure and fix problems.
We don't sell your data, use it for advertising or train models on it. We don't look at your conversations or memories; we access related data only when you ask us to investigate a problem and agree, or when the law requires it.
3. Who processes it
- DigitalOcean (server hosting, San Francisco, USA): stores all the server-side data above.
- DeepSeek (China): to generate replies, memory suggestions, summaries and plan drafts, the relevant conversation content, memories and your plans for the day are sent to DeepSeek's API. DeepSeek processes them under its API terms.
- Cloudflare: provides DNS for our domain only; your data does not pass through Cloudflare.
- Let's Encrypt: issues our HTTPS certificates; it never sees your data.
We don't share your data with anyone else.
4. Where data is stored, and transfers
Our servers are in the United States. Generating replies sends the relevant content to DeepSeek in China. By using Matcha you agree that your data is transferred to and processed in the United States and China.
5. How long we keep it
- Your account and content are kept until you delete them or your account.
- Deleting a memory or conversation takes effect immediately. Deleting a conversation also deletes the memories and summaries that came only from it.
- Deleting your account removes all your Matcha data at once; your sign-in account is then deleted by a background task, usually within seconds, retried for up to an hour if it fails.
- We back up the database daily and keep backups for 30 days. Deleted data may remain in backups until they expire; if we restore a backup, we re-apply every account deletion made since.
- Sign-in records are kept for at most 30 days; after you delete your account, your sign-in records are removed within a day.
- Server logs rotate by size, up to about 50 MB per service, typically days to weeks.
- After deletion we keep only two things: a hash computed from your sign-in id, so old credentials cannot recreate the account (it cannot be turned back into your username), and one "account deleted" record with no content.
6. Your rights
- View and change: view, edit and delete your memories, conversations, tasks and dates in the app at any time.
- Export: Settings → Your data → Export gives you one file with all your data. Vectors used to find memories can be recomputed from the content, so they are left out.
- Delete: Settings → Account → Delete account removes all your data and your sign-in account.
- For anything else, such as correcting information or asking how your data is processed, contact us below.
7. Security
All connections use HTTPS; each person's data is isolated in the database itself, so one account cannot read another's; our servers accept key-based logins only. Matcha is in beta: the service may be interrupted and data may be lost through a fault, so please export what matters to you from time to time.
8. Children
Matcha is not meant for children under 14. If you find that a child used Matcha without a guardian's consent, contact us and we will delete the account and its data.
9. Changes
This policy may change as Matcha changes; we update the effective date when it does. Important changes, such as collecting new data or a new third party, are announced in the app or on the website in advance.
10. Contact
Matcha is run by an individual developer. For any privacy question or request, e-mail privacy@matcha-mini.com.
