一句話總結：SideBell 不蒐集、不上傳、不分享你的任何資料。呼叫透過藍牙在你自己的兩台裝置之間直接傳送，不經過任何伺服器；App 沒有帳號系統、沒有分析工具、沒有廣告。
我們蒐集哪些資料
沒有。SideBell 沒有帳號系統、沒有自建伺服器、沒有第三方分析工具。你在 App 內產生的所有內容都只存在你自己的裝置上：
- 呼叫項目（名稱、順序）：儲存於患者端裝置本機。
- 角色設定與使用紀錄（選擇了患者端或照顧者端、是否已閱讀免責聲明）：儲存於各自裝置本機。
- 呼叫紀錄：只存在照顧者端當次執行的記憶體中，App 關閉即消失，不寫入任何檔案。
呼叫怎麼傳送
兩台裝置以藍牙低功耗（BLE）直接連線。呼叫內容不經過網際網路、不經過開發者的伺服器（我們沒有伺服器），也不經過任何第三方。這也是 SideBell 在斷網、停電環境下仍能運作的原因。
支持開發者（App 內購買）
App 內的「支持開發者」為選用的一次性小額贊助，不解鎖任何功能。購買流程由 Apple App Store 處理，開發者不會、也無法取得你的付款資訊。
我們使用 RevenueCat 驗證購買。它會收到交易紀錄與一組隨機產生的匿名識別碼；本 App 不會傳送你的姓名、電子郵件、Apple ID 或任何可識別個人身分的資訊給它。「曾經支持過」這個狀態只記在你的裝置本機，不向任何伺服器查詢。
權限用途
- 藍牙：這是 App 的核心功能，用於在患者端與照顧者端之間傳送呼叫。不用於定位、不用於掃描周遭裝置做任何其他用途。
- 通知：僅在照顧者端請求，用於在 App 位於背景時把呼叫顯示在鎖定畫面。全部是本機通知，不經過推播伺服器。
我們不做的事
- 不要求註冊或登入帳號。
- 不將任何資料傳送到開發者的伺服器（我們沒有伺服器）。
- 不使用任何第三方分析 SDK。
- 不顯示廣告、不進行任何形式的追蹤（不跳 ATT、不使用 IDFA）。
- 不販售你的資料。
資料刪除
所有資料都在你的裝置上。刪除 App 即一併刪除全部內容，不需要另外提出申請——我們手上本來就沒有你的任何資料。
兒童
本 App 適合一般使用者，不刻意蒐集任何年齡層的個人資料。
政策變更
若未來調整資料使用方式，本政策會隨之更新，並於此頁標註更新日期。

English
In one sentence: SideBell does not collect, upload, or share any of your data. Calls travel directly between your own two devices over Bluetooth and never pass through a server. There is no account system, no analytics, and no advertising.
What we collect
Nothing. SideBell has no account system, no server of our own, and no third-party analytics. Everything you create stays on your own devices:
- Call items (names, order): stored locally on the patient's device.
- Role and setup state (whether this device is the patient or caregiver side, whether the notice has been acknowledged): stored locally on each device.
- Received calls: held only in memory on the caregiver's device for the current session; they disappear when the app closes and are never written to a file.
How calls are delivered
The two devices connect directly over Bluetooth Low Energy. Call content never travels over the internet, never reaches a developer-run server (we don't have one), and never passes through any third party. This is also why SideBell keeps working without Wi-Fi or during a power cut.
Supporting the developer (in-app purchases)
The "Support the developer" option is an optional one-time tip that unlocks nothing. Purchases are handled entirely by the Apple App Store; the developer does not and cannot receive your payment details.
We use RevenueCat to validate purchases. It receives the transaction record and a randomly generated anonymous identifier. The app does not send your name, email address, Apple ID, or any personally identifying information to it. The "has supported" state is stored only on your device and is never queried from a server.
Permissions
- Bluetooth: the core function — delivering calls between the patient and caregiver devices. It is not used for location or for scanning nearby devices for any other purpose.
- Notifications: requested on the caregiver side only, so calls arriving while the app is in the background can appear on the lock screen. These are local notifications and do not involve a push server.
What we don't do
- No sign-up or login required.
- No sending data to any developer-run server (we don't have one).
- No third-party analytics SDKs.
- No ads and no tracking of any kind (no ATT prompt, no IDFA).
- We do not sell your data.
Deleting your data
All data lives on your devices. Deleting the app removes everything — no request needed, because we never had any of it.
Children
This app is for a general audience and does not knowingly collect personal data from anyone.
Changes to this policy
If we change how data is used, this policy will be updated and the date above revised.
