Privacy Policy — TsuiuChat
Last updated: 26 July 2026
TsuiuChat is built around a simple idea: your AI conversations should stay yours. This app has no user accounts and no backend server operated by the developer. Here is exactly what that means.
What stays on your device
Your conversations, custom characters, imported documents, and settings are stored only in the app's local storage on your iPhone. The developer cannot see, access, or receive any of this data — there is no server to send it to.
By default, chat content is excluded from iCloud backup. You can turn this on in Settings if you want your conversations backed up to your own iCloud.
Third-party services this app connects to
- Model downloads — the AI models that run on your device are downloaded directly from Hugging Face (or a regional mirror) the first time you use them. This is a one-way file download, not a data upload.
- Web search (optional, user-triggered) — when you use the search feature, your device queries public sources (news publishers, Wikipedia, DuckDuckGo/Bing/Baidu, Open-Meteo) directly. We do not operate a proxy and do not see your queries.
- Self-hosted / cloud model bridge (optional, user-configured) — if you connect the app to your own Ollama/LM Studio server or to a cloud AI provider using your own API key, your messages go directly between your device and that endpoint. We have no visibility into that traffic.
- In-app purchase — the one-time Pro purchase is processed entirely by Apple through StoreKit. We never see your payment information.
Data we collect ourselves
None. This app has no analytics SDK and no first-party tracking of any kind. Crash and performance diagnostics are recorded locally through Apple MetricKit and are never uploaded automatically.
If you choose to send a problem report, it includes only what you wrote plus basic diagnostics (app version, device model, OS version, recent debug log). It never contains your conversations, and it is sent only when you tap send.
Children
This app is rated 13+ and is not directed at children.
Content you create
Any character, story, or conversation you write stays on your device. If you delete the app, that data is gone — there is nothing on a server to also delete.
Changes
If this policy changes, the updated version will be posted at this same URL with a new "Last updated" date.

隱私權政策 — TsuiuChat
最後更新:2026 年 7 月 26 日
TsuiuChat 建立在一個簡單的想法上:你的 AI 對話應該屬於你自己。這個 App 沒有使用者帳號, 開發者也沒有任何後端伺服器。以下具體說明這代表什麼。
留在你裝置上的資料
你的對話、自訂角色、匯入的文件與設定,只儲存在你 iPhone 上 App 的本機儲存空間。開發者無法查看、 存取或接收這些資料——因為沒有任何伺服器可以送去。
對話內容預設不納入 iCloud 備份。若你希望對話備份到自己的 iCloud,可以在設定中開啟。
App 會連線的第三方服務
- 模型下載——在你的裝置上運行的 AI 模型,會在第一次使用時直接從 Hugging Face (或區域鏡像)下載。這是單向的檔案下載,不是資料上傳。
- 網路搜尋(選用,由你主動觸發)——使用搜尋功能時,你的裝置直接向公開來源查詢 (新聞媒體、Wikipedia、DuckDuckGo/Bing/Baidu、Open-Meteo)。我們沒有中介伺服器,也看不到你的查詢。
- 自架 / 雲端模型橋接(選用,由你自行設定)——若你選擇連接自己的 Ollama/LM Studio 伺服器,或用自己的 API Key 連接雲端 AI 供應商,你的訊息是在你的裝置與該端點之間直接傳輸, 我們無從得知這些流量。
- App 內購買——一次性買斷的 Pro 購買,全程由 Apple 透過 StoreKit 處理, 我們不會看到你的付款資訊。
我們自己收集的資料
沒有。這個 App 沒有分析 SDK,也沒有任何第一方追蹤。當機與效能診斷透過 Apple MetricKit 記錄在本機, 不會自動上傳。
若你主動送出問題回報,內容只包含你填寫的描述加上基本診斷資訊(App 版本、裝置型號、系統版本、 最近的除錯紀錄),不含你的對話內容,而且只有在你按下送出時才會寄出。
兒童
本 App 分級為 13+,並非以兒童為對象。
你創作的內容
你寫的任何角色、故事或對話都留在你的裝置上。刪除 App 就等於刪除這些資料——伺服器上沒有另一份副本 需要處理。
政策變更
若本政策有所變更,更新版本會發佈在同一個網址,並標示新的「最後更新」日期。
