English: Your diet profile and health-related preferences are stored on your device by default. We do not sell personal data. If you turn on optional features such as online search or cloud AI, only the food-related text needed for nutrition analysis is sent, and only when you use those features. You can edit or delete entries in the app at any time; email us for other privacy requests.

中文：饮食档案与健康相关偏好默认保存在你的设备本机；我们不会出售个人数据。若你主动开启联网搜索或云端 AI 等可选功能，仅在你使用时发送与营养分析相关的食物文本。你可随时在 App 内修改或删除条目；其他隐私诉求请发邮件联系我们。

English: Pure Fuel combines ingredient knowledge, public nutrition databases, dietary guidelines, and similar trusted references, with on-device or optional AI to synthesize guidance. This does not guarantee completeness or correctness for every person or situation—individual health conditions, data gaps, and model limits all matter. Use it as everyday reference only, not as medical diagnosis or treatment.

中文：Pure Fuel 会综合食材知识、公开营养数据库、膳食指南等可靠参考资料，并由本地或可选 AI 辅助归纳评价。受个体差异、数据缺口与模型能力等限制，我们无法保证对每一个人都完全准确或详尽，仅供日常饮食参考，不能替代医疗诊断或治疗。

答：不会。首次问卷会自动写入档案，后续在“我的”中可继续修改。
