Frequently asked常见问题

Where is my data? Everything stays on your device. There are no accounts and no cloud sync. To move your history to another device, use Settings → Export Data and import the file on the other device.我的数据在哪里？一切都保存在你的设备上。没有账户，也没有云端同步。若要把记录迁移到另一台设备，请使用“设置 → 导出数据”，再在另一台设备上导入该文件。

Where does the substance data come from? It's merged from nine sources — TripSit, PsychonautWiki, FDA DailyMed, Erowid, DrugBank, PubChem/Wikidata, drug.community, peer-reviewed literature, and a hand-curated overlay — and bundled in the app. Every field shows its source, and you can reorder which sources you trust first in Settings → Sources.物质数据来自哪里？由九个来源逐字段合并——TripSit、PsychonautWiki、FDA DailyMed、Erowid、DrugBank、PubChem/Wikidata、drug.community、同行评审文献，以及人工校订层——并内置于 App。每个字段都标注来源，你也可在“设置 → 来源”中调整优先信任的顺序。

Is the interaction checker medical advice? No. It shows known interactions to inform you, but should never replace professional medical advice.相互作用检查算医疗建议吗？不算。它显示已知的相互作用以供参考，但绝不应替代专业的医疗意见。

Troubleshooting故障排查

• Live Activity not showing? Check that you've enabled it in Settings and that Background App Refresh is on for Piru.实时活动没有显示？请确认已在“设置”中启用，并为 Piru 开启“后台 App 刷新”。
• Substance data looks outdated? Open Settings → check for a database update (if you've enabled updates).物质数据看起来过时？打开“设置”→ 检查数据库更新（前提是你已启用更新）。
• Hit a crash? Tell us your iOS version and what you were doing when it happened — it helps a lot.遇到崩溃？请告诉我们你的 iOS 版本以及崩溃时正在进行的操作——这对我们排查很有帮助。

Disclaimer免责声明

Piru is a reference and a record, not a doctor. It tells you what is known about a substance, and what you've logged — it can't tell you what is safe for you. Always consult a qualified healthcare professional for medical advice.Piru 是一部参考、一份记录，而非医生。它告诉你某种物质的已知信息，以及你所记录的内容——但无法判断什么对你是安全的。请始终就医疗问题咨询合格的专业医疗人员。
