APP SUPPORT
先查看常见问题；仍需帮助时，可通过支持邮箱联系牙历。
请在 iPhone 设置中允许牙历访问麦克风和语音识别，并确认设备已下载对应语言。语音识别和预约字段解析在兼容设备上本地完成。
请确认网络连接后重试，并在保存前核对识别结果。不要在普通邮件中发送真实患者照片或完整病历。
请确认当前设备登录的是原购买 Apple 账户，然后在牙历设置中选择“恢复购买”。恢复购买不会恢复本机预约数据。
若 Face ID 也无法使用，只能清除 App 本机数据后重新初始化。备份密码无法找回，请妥善保存。
请提供牙历版本、iOS 版本和问题发生步骤，不要发送患者姓名、预约照片、牙位或病历内容。
Allow microphone and speech-recognition access in iPhone Settings and make sure the required language is available on the device.
Check your connection and try again. Review every result before saving. Do not email real patient images or complete medical records.
Sign in with the Apple account used for the original purchase, then choose Restore Purchases in Dental Calendar Settings. This restores entitlements, not local appointment data.
If Face ID is also unavailable, local app data must be cleared before setup can begin again. Encrypted-backup passwords cannot be recovered.
Include the app version, iOS version, and steps to reproduce. Do not send patient names, appointment images, tooth details, or medical records.
