兩端目前透過 TestFlight 私下測試。若遇到問題，請使用 TestFlight 的 Beta Feedback，我們會在同一個管道回覆。
回報問題
- 在手機上開啟 TestFlight。
- 選擇「兩端」，點「傳送 Beta 意見」。
- 描述問題，並附上截圖（如果方便）。
請盡量附上：
- 手機型號與 iOS 版本
- App 版本與建置編號（設定頁最下方）
- 發生前的操作步驟，以及是否每次都重現
- 當下使用的是 Wi-Fi 還是行動網路
帳號與資料
- 刪除帳號：設定 → 資料與隱私 →「刪除帳號與所有資料」。此操作無法復原；你送出的訊息與附件會從雲端移除。
- 清除本機暫存：設定 → 資料與隱私 →「清除這台手機的離線快取」。雲端訊息不受影響。
- 換手機：用同一個信箱登入即可取回帳號與聊天室。
目前的功能限制
- 尚未提供背景推播：App 在背景或鎖屏時，不會收到新訊息或來電通知。
- 僅提供語音通話，沒有視訊。
- 目前沒有端對端加密；傳輸使用 TLS，雲端服務管理者在技術上仍可能存取內容。
- 跨國通話品質（加拿大 ↔ 中國大陸）尚未完成實測。
隱私
我們收集與處理資料的方式，請見隱私權政策。

Between is currently distributed privately through TestFlight. If you run into a problem, use TestFlight's Beta Feedback and we will reply through the same channel.
Report a problem
- Open TestFlight on your phone.
- Select Between and tap "Send Beta Feedback".
- Describe the issue and attach a screenshot if you can.
Please include the phone model, iOS version, app version and build number, the steps that led to the issue, whether it reproduces every time, and whether you were on Wi-Fi or cellular.
Account and data
- Delete account: Settings → Data & Privacy → "Delete account and all data". This cannot be undone; messages and attachments you sent are removed from the cloud.
- Clear local cache: Settings → Data & Privacy → "Clear this phone's offline cache". Cloud messages are unaffected.
- New phone: sign in with the same email to restore your account and rooms.
Current limitations
- No background push yet: new messages and incoming calls do not arrive while the app is in the background or the phone is locked.
- Voice calls only; there is no video.
- No end-to-end encryption yet. Transport uses TLS, and the cloud service operator could technically access content.
- Cross-border call quality (Canada ↔ mainland China) has not been fully tested.
